CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to and is a continuation of U.S.
patent application Ser. No. 15/480,914 titled "System for Connecting
Implement to Mobile Machinery," filed Apr. 6, 2017, which claims the
benefit of U.S. Provisional Patent Application No. 62/390,693 titled
"Laterally adjustable 3-point hitch attachment device" filed Apr. 7, 2016
and U.S. Provisional Patent Application No. 62/496,424 titled "Laterally
adjustable three-point hitch implement apparatus," filed Oct. 18, 2016,
the contents of which are incorporated herein by reference in their
entirety.
BACKGROUND
[0002] Mobile machinery such as agricultural tractors, bulldozers, track
tractors, skip loaders, all-terrain vehicles and earth grading tractors,
generally referred to as a "tractor," typically are provided with a
suitable power plant, a source of fluid under pressure and or a source of
electric current. The fluid pressure source includes suitable valve
control means. The tractors typically include an implement mounting
system known as a three-point hitch. The three-point hitch includes a
pair of opposed spaced apart lateral bottom-link arms located at the rear
of the tractor body or frame rotatably connected to the tractor with ball
joints which are affixed to the frame or body of the tractor at a
selected distance of typically 12 to 30 inches above the ground and
extend on each side of a center draw bar. The free distal ends of the
arms typically include a ball rotatable in a socket with an axial hole
extending there through.
[0003] A third arm, called a top-link arm, is also rotatably connected
with a ball joint to the tractor frame at a point about 30 to 60 inches
above ground and centered above the bottom-link arms. The free distal end
of the top-link arm is fitted with a rotatable ball with an axial hole
extending there through for connecting to a center point on an implement
in alignment with studs. Free ends of the two bottom-link arms and the
top-link arm provide three-points of attachment to implements and
therefore is referred to as a three-point hitch. The length of top-link
arm is generally adjustable by means of a built in turn-buckle assembly.
This provides for manual leveling of the attached implement. The top-link
arm turn buckle assembly can be replaced with a hydraulic cylinder for
quick controlled manual or automated adjustments of the length of the
top-link arm resulting in adjustments of the attached three-point
implement.
[0004] The bottom-link arms are connected to a lift-link arm to provide a
means for lifting such as a suitable power lift mechanism, for example
one or more hydraulic cylinders. This provides the capability to raise
and lower the two bottom-link arms and thus the implement which is
connected to the three-point hitch. Because the free ends of all three
arms are connected to the tractor with ball joint type connections, all
three arms may freely pivot to the left and the right any time the
three-point hitch has the implement raised off the ground. On older
tractors, an additional bar called a stabilizer arm is provided, if
desired, and is connected to one of the first two bottom-link arms and to
a fixed point on the tractor. On newer tractors, two stabilizer arms are
provided, one for each bottom-link arm and they are also connected to a
fixed point on the tractor. The stabilizer arms allow the bottom-link
arms to still be raised and lowered by hydraulic means, but the implement
is held stable with reference to the horizontal plane, and cannot swing
to and fro as before.
[0005] The attached implement can include a transversely extending tool
bar or frame member having laterally spaced apart studs extending from
the front tractor-facing side of the implement for removable attachment
to the sockets held within the distal ends of the bottom-link arms. In
addition to the bottom-link arm attachment hardware means is an upper
attachment hardware means for the attachment of the top-link arm.
[0006] A three-point hitch is standard equipment on most agricultural and
earth grading tractors. The use of a three-point hitch provides lifting,
lowering and tilting mechanisms to attached agricultural implements, such
as agricultural implements. The tractor three-point hitch allows the
attached tool or implement to be raised and lowered, tilted horizontally
and tilted vertically, all such movements and adjustments provided by
hydraulically activated cylinders or manual crank screw devices. Front
three-point hitches, while available, are less common than rear
three-point hitches on agricultural tractors.
[0007] The three-point hitch provides for a quick attachment of various
implements needed on a tractor. In addition, when the implement is in the
raised or lowered position, lateral movement of the three-point
bottom-link arms is freely available. To limit lateral movement of the
implement in the raised or lowered position, the user can add a
stabilizer arm comprising a longitudinal member having a selected
adjustable length attachable to a swing arm attachment point on the
tractor body or frame with the opposing end attaching to the same
implement stud as the adjacent swing arm to limit lateral movement of the
bottom-link arms. Many tractor brands are now factory supplied with
three-point hitch bottom-link stabilizer arms. Controlled lateral
movement of an attached implement is not provided with a three-point
hitch.
[0008] Earth-moving equipment in the construction and farming field has
rapidly changed for the better in recent years with the introduction of
Global Positioning Systems (GPS) and laser guidance systems. Current GPS
guidance systems for earth-moving and agricultural tractors generally are
designed to auto-steer the tractor. Much of the guidance involves
steering the tractor in a straight line to form a straight road or
straight row of crops. Since most agricultural and earth grading tractors
are steered by the front end of the tractor, the rear end mounted
three-point hitch attached implement may not align in a straight line
with the front steered end of the tractor. This misalignment would
normally occur while the tractor is turning 180 degrees around at the end
of the crop row and then joining onto the next crop row in the other
direction. This misalignment would also occur while the tractor is in the
middle of the crop field and the tractor veered slightly off line of the
crop straight line forcing the tractor operator to correct the steering
of the tractor. This steering correction of the tractor can also shift
the rear end of the tractor in the opposite direction of the steering
correction causing the rear three-point connected implement to also veer
off course of the straight crop row and possibly damage the crops while
cultivating the field or misalign the crops while planting. Lasers have
come into play in the earth-moving and agricultural field mostly by
controlling grade leveling implements on the tractor in an up and down
motion for achieving a level or sloped grade.
[0009] Conventional laterally moving implement toolbars pivot on four
parallel supporting arms extending out from the front of the supporting
frame. Short sized supporting arms provide limited lateral movement of
the toolbar section of the implement. The short lateral movement is
exacerbated by the positioning of the tool mounting bar being too close
to the frame structure that mounts to the tractor three-point hitch.
Mounting brackets further decrease the tool mounting bar clearance to the
frame structure. Pivoting-support-arms pivot in either direction limiting
the length of the lateral movement to much less than the length of the
pivoting-support-arms. The weight that these pivoting-support-arms can
support on the toolbar with heavy implements is dependent on the strength
of the pivot arms and their pivot joints. The pivot joints need to
sustain a tremendous weight load when handling a heavy implement as they
pivot side to side. This weight load is compounded and increased if the
pivoting-support-arms are increased in length.
[0010] Two-point hitch configurations present a different set of
limitations for use of lateral connection devices. The three-point hitch
invention differs from a two-point hitch in the mounting ability by
utilizing the advantage of the top-link arm attachment to the tractor
frame, the improved locations for the sleeves that provide the sliding
housings, a more versatile and stable two tier stacked movable implement
attachment section compared to the one movable toolbar and a more stable
and functional two or more tiered stacked movable implement attachment
section compared to the one movable implement attachment section.
[0011] Several patents teach methods of steering and controlling tractor
mounted implement attachment systems to two-point and three-point hitch
systems. U.S. Pat. No. 3,208,535 by Fischer teaches an automatic steering
system for implements; U.S. Pat. No. 7,530,405 by Kollath et al. teaches
a quick coupler mechanism, U.S. Pat. No. 4,019,753 by Kestel teaches an
adjustable three-point tractor hitch; U.S. Pat. No. 4,463,811 by Winter
teaches an implement with a laterally movable frame structure with
limited lateral movement; and U.S. Pat. No. 5,931,234 by Trowbridge
teaches a retractable three-point hitch mounted, vertically and laterally
adjustable toolbar. U.S. Pat. No. 4,930,581 by Fleischer teaches a
guidance control device for agricultural implements using a hydraulic
cylinder to pivot the implement frame and implement to the left or to the
right to correct lateral position with respect to the tractor and the
previously processed rows. U.S. Pat. No. 3,208,535 by Fischer teaches an
automatic steering device and a plant stem sensor.
[0012] Existing systems for pulling or pushing implements suffer from a
significant disadvantage, particularly that the implement can go off
course, particularly during turns. This can result in destroyed crops,
inadequate application or over application of chemicals used for crops,
unplowed soil, and other deleterious effects. These problems can occur
even when the mobile machinery, such as a tractor, is on course.
[0013] Therefore, there is a need for a system that can allow an implement
to be pushed or pulled that helps maintain the implement on track, even
when the mobile machinery used for pulling or pushing the implement is
off track.
SUMMARY
[0014] A system according to the present invention that satisfies this
need includes a connecting apparatus suitable for connecting an implement
to a three-point hitch of mobile machinery, such as a tractor. The
connecting apparatus comprises a first framework disposed in a first
plane and comprising at least two parallel, vertically spaced-apart,
laterally extending rails. Three attachments are supported by the first
framework for attachment to the three-point hitch. The slidable second
framework is generally in the plane of the first framework and is mounted
on the rails to slide laterally along the rails. At least two connectors,
and typically three connectors, are supported by the slidable second
framework for connecting the slidable second framework to an implement
that can be pulled or pushed by the mobile machinery. At least one
driver, and for a robust apparatus, two drivers, are connected to the
first framework and connected to the second framework for driving the
slidable framework laterally back and forth along the rails.
[0015] In use of the apparatus, the position of the implement relative to
the mobile machinery is changed by the action of the driver, the driver
laterally moving the second framework.
[0016] Typically, the first framework comprises an upper cross beam and a
lower cross beam, each cross beam substantially parallel to the rails. In
a preferred version the first framework comprises at least two rails, at
least two vertically extending studs, the upper cross beam, and the lower
cross beam. The upper cross beam can support one of the attachments and
the lower cross beam can support two of the attachments, typically in a
triangular configuration.
[0017] The driver can be at least one hydraulic cylinder or at least one
electric linear actuator.
[0018] When a cylinder is used as part of the driver, the cylinder can be
provided with a stop for limiting lateral movement of the second
framework. The driver can be manually or automatically controlled. The
manual control can be a lever or the like. Also a switch can be provided
for switching between manual and automatic control.
[0019] Preferably there is a guidance system for automatically controlling
the driver to position the slidable second framework in a predetermined
pathway. The guidance system can comprise a GPS receiver, an underground
(buried) or above ground guidance wire, or a position signal receiver for
receiving a laser signal. The guidance system can comprise at least one
GPS positioning receiver mounted on the second framework for receiving
signals from the satellites or ground mounted base relay station to
determine the position of the slidable second framework, and a controller
for receiving position signals from the position signal receiver, the
controller adapted to control the driver to position the slidable second
framework in the predetermined pathway. The GPS guidance system utilizes
data input into a data input monitor to set the predetermined coordinates
of the mobile machinery and the connecting apparatus. GPS guidance can
control the mobile machinery steering in addition to the connecting
apparatus position. GPS positioning of the connecting apparatus in
conjunction with GPS steering of the mobile machinery is an advantage
over GPS steering of the mobile machinery alone while attempting to guide
an attached implement along a predetermined pathway. In a guidance wire
application, the guidance system can comprise at least one sensor mounted
on the second framework for receiving signals from the guidance wire. The
apparatus can comprise a position signal receiver supported by the
slidable second framework for determining the position of the slidable
second framework, and a controller for receiving position signals from
the position signal receiver, the controller adapted to control the
driver to position the slidable second framework in the predetermined
pathway. The guidance system can comprise at least one laser position
receiver for receiving a laser signal from a rotating vertical laser
transmitter, and a controller for processing position signals from the
position signal receiver, the controller adapted to control the driver to
position the slidable second framework in the predetermined pathway. In a
laser guidance application, generally there is no need for data entry
into a data entry monitor. The position of the laser receiver on the
connecting apparatus can position the connecting apparatus and steer the
tractor if tractor steering is preferred.
[0020] The second framework can comprise at least one sleeve for sliding
on at least one rail, and typically multiple sleeves for sliding on
multiple rails.
[0021] To power the driver, the apparatus can include a power receptacle
for receiving power from the mobile machinery, which can be electric
power or hydraulic fluid power.
[0022] For implements that have more than three places for connection,
there can be more than three connectors, such as four or more connectors.
[0023] To assist an operator of the mobile machinery, the apparatus can
include a light fixture and at least one camera.
[0024] In a preferred version of the invention, for robustness, the first
framework comprises four rails, and the second framework comprises four
lateral substantially parallel sleeves connected at their ends by end
posts, each sleeve slidable on one of the rails.
[0025] It is preferred that there be positioning indicia on the upper
cross beam of the first framework for positioning the second framework
relative to the first framework. This same type of positioning indicia
can be used on the lower cross beam of the first framework. Also, there
can be positioning indicia on one or more of the sleeves for adjusting
the position of any connector supported by the sleeve.
[0026] Preferably the apparatus includes a sensor for sensing the position
of the second framework relative to the first framework. This can be
combined with an alert generator that generates an alert, such as a sound
or flashing light, when the sensor senses that the second framework
slides beyond a predetermined position.
[0027] Preferably the apparatus includes a plumb gauge and a level gauge
for correctly adjusting the attitude and positioning of the implement.
[0028] Preferably at least one connector is laterally adjustable on the
second framework. Also preferably at least one connector is vertically
adjustable on the second framework.
[0029] Additionally, the apparatus can include a connection guidance
system for connecting the apparatus to the implement, the connection
guidance system comprising a sensor on at least one, and preferably at
least two, connectors for sensing the position of the implement. With the
connection guidance system, the system can include a method for
connecting the apparatus to the implement, where the implement has
hitches for connector with the connectors. The method comprises placing
the implement and apparatus approximate to each other, determine the
alignment of the connectors and the hitches, and adjusting the alignment
by sliding the second framework relative to the first framework.
[0030] The invention also includes a system where the mobile machinery,
the apparatus described above, and an implement are connected together,
with the apparatus attached to the mobile machinery via the three-point
hitch on the mobile machinery, and the implement attached to the slidable
second framework with at least two connectors.
[0031] The system can also include a pair of support stands for supporting
the apparatus when the apparatus is otherwise not well supported, such as
not being attached to all three points of a three point hitch, each stand
comprising pins for engaging corresponding holes in the vertical studs of
the first framework. Clips can be used for holding the pins in their
engagement position.
[0032] Multiple connection apparatus of the present invention can be daisy
chained together such as having a central apparatus attached to the
mobile machinery, and having an additional pair of the apparatus, each
one of the pair pivotally and removably attached to the sides of the
central apparatus. Each of the pair can be modified from the central
apparatus such as for the driver location and driver connection between
the first and second framework. Each of the outer pair is typically
designed to carry lighter duty implements than the central apparatus.
[0033] A system according the present invention comprises: [0034] a)
mobile machinery having a three-point hitch; [0035] b) the connection
apparatus attached to the mobile machinery with the three attachments;
and [0036] c) an implement attached to the slidable second framework with
at least two connectors.
[0037] In a method of using the system there are the following steps:
[0038] a) placing the implement and apparatus proximate to each other;
[0039] b) determining the alignment of the connectors and the hitches;
and [0040] c) adjusting the alignment by sliding the second framework
relative to the first framework.
[0041] In a method for changing the position of an implement pulled or
pushed by with mobile machinery, the mobile machinery having a
three-point hitch, there are the steps of: [0042] a) attaching the
connection apparatus to the three-point hitch of the mobile machinery
with the three attachments; [0043] b) attaching the implement to the
slidable second framework with the connectors; and [0044] c) changing the
lateral position of the implement relative to the mobile machinery with
the driver.
[0045] According to the invention, a method of attaching an implement to
mobile machinery comprises the steps of: [0046] a) attaching the
connecting apparatus to the mobile machinery with the attachments; [0047]
b) aligning the connectors of the slidable second framework with the
implement by moving the second framework relative to the first framework;
and [0048] c) connecting the connectors to the implement.

[0297] FIG. 1a shows the positions of a front and rear three-point hitch
as they are combined with a tractor 38 in the prior art. This side view
shows a Carry-All implement 300 mounted to the front and rear three-point
hitches of a tractor 38. Shown are the three points of attachment of a
three-point hitch to the Carry-All implement 300 using two bottom-link
attachment arms 318 and a top-link attachment arm 324. Two bottom link
attachment arms 318 (see FIG. 2) are generally positioned on the same
horizontal plane unless an application of use requires otherwise. Lift
link arms 330 are visible on the front three-point hitch while not being
visible on the rear three-point hitch being hidden by the larger rear
tires. In many farming and excavating instances a rear three-point hitch
is used by itself without a front three-point hitch being attached to the
tractor 38. Using a combined front and rear three-point hitch can
increase the efficiency of the farming or excavation application if used
properly.
[0298] FIG. 1b shows schematically a system according to the present
invention comprising a first connecting apparatus 40 attached to the
front and rear three-point hitches of a tractor in addition with the
Carry-All implement 300 mounted to the first connecting apparatus 40 at
front and rear locations. The connection apparatus 40 mounts first to the
three-point hitch of the tractor and the Carry-All implement 300 next
mounts to the connection apparatus 40.
[0299] FIG. 1c shows a close-up side view showing a tractor with the
connection apparatus 40 mounted to the rear three-point hitch of a
tractor with the prior art Carry-All implement 300 mounted to the
connection apparatus showing top-link arm 324 attaching to the
rigid-frame top-link attachment 66, and the bottom link arms 318
attaching to the rigid-frame bottom-link connection points 68 of the
connection apparatus 40. Sliding frame bottom-link quick hitch hook and
stop bar 136 attaches the lower portion of the Carry-All implement 300 to
the sliding-frame 46 and sliding-frame top-link hook and stop bar 130
attaches the upper portion of the Carry-All implement 300 to the
sliding-frame 46. The sliding frame can be guided with a system using a
buried guidance wire 141 utilizing a signal generator 143 to activate the
guidance wire 141.
[0300] FIG. 2 shows the prior art implement 300, that includes a top
attachment receiver 312 which usually comprises a pair of spaced apart
aligned projections or flanges centrally disposed and having a hole there
through for receiving a distal end 326 of the top-link arm 324 which is
releasably held thereto by a pin or bolt 310. The distal end 326 can
comprise a socket. The opposing end 322 of the top-link arm 324 also
comprises a distal ball socket for attachment to the tractor top-link
attachment location with similar spaced apart projections and retaining
pin or bolt. The implement 300 typically includes a transversely
extending tool bar or frame member having laterally spaced apart studs
314 extending from the tractor-facing side of the implement frame for
removable attachment to the bottom-link arm 320 sockets held within the
distal ends of the bottom-link arms 318. In the alternative, laterally
spaced apart studs 314 are replaced with two flanges with axial centered
holes 195 (see FIG. 24) with a pin therein for connection to the
bottom-link arms 318. The distal end 326 of the top-link arm 324 and
distal ends 320 of the two bottom-link arms 318 contain within sockets
having rotatable balls including apertures extending there-through for
insertion of pins for connecting these three ends to fixed points on the
implement. The top-link arm 324 includes a turn-buckle assembly with
threaded rods and a threaded hollow cylinder which can be rotated to
lengthen or shorten the overall length of the top-link arm 324.
[0301] FIGS. 3 shows prior art lift-link arms 330 connect at lift-link
arms connection to bottom-link arms 332 that cause the bottom-link arms
318 to rotate upward and downward pivoting the proximate ends of the
bottom-link arms on a spindle and raising the distal end of the
bottom-link arms 320 and the implement attached thereto. The top-link arm
324, in turn, causes the upright portion of the carry-all implement 300
to maintain general uprightness or verticality. Consequently, the
horizontal portion of the implement remains generally horizontal
throughout the upward and downward motion of the carry-all implement 300
(see FIG. 2). Because the bottom-link arms 318 points of attachment to
the tractor under-carriage location 316 are also ball and socket
arrangements, the implement is free to move laterally a fixed distance
providing "play" for with respect to the tractor. In some situations,
this freedom of movement is desirable, and in other situations,
undesirable. As in the case of this present invention, the freedom of
movement situation is undesirable, additional stabilizer arms are
connected, one to each of the bottom-link arms. One end of the stabilizer
arms connected approximately half way down the length of each bottom-link
arm 338, the other end is connected to a fixed point on the tractor
under-carriage location 334 which is coaxial with the two bottom-link arm
connections to the tractor under carriage at location 316. This allows
full up and down movement of the implement but removes any random lateral
motion of the implement. The stabilizer arms 336 may be a turn-buckle
assembly with threaded rods and a threaded hollow cylinder which can be
rotated to lengthen or shorten the overall length of the stabilizer arm.
In the alternative, the stabilizer arms may be a rigid arm with an
adjustable threaded screw device located at the bottom-link arm location
338. Another alternative to the above stated stabilizer arms is one or
two stabilizer arms connected to a rigid point on the tractor and the
other end connected crossways to one or both of the bottom-link
connection pins 314 (see FIG. 2) to the implement.
[0302] Bottom-link arms 318 support the weight of the implement. Lift-link
arms 330 attach between the bottom-link arms 318 and tractor hydraulic
actuated lift arms at connection point 328. The adjustable top-link arm
324 attaches to the tractor mounted top-link bracket 340 with a removable
pin or bolt thru the top-link arm distal end 322, which can have a
mounted rotatable ball, while the opposed distal end 326 of the top-link
arm has a rotatable ball and attaches to a top-link attachment plate 312
on the implement as shown in FIG. 2. A Power Take-Off shaft (PTO) (not
shown) can be disposed centered on the rear of the tractor through the
PTO pathway 98 in a plane between the height of the top-link attachment
plates 340 on the tractor and the bottom-link attachments 316 to the
tractor.
[0303] FIG. 5 and FIG. 6 show the tractor-facing side of the laterally
adjustable three-point hitch implement attachment, of a first version of
the invention, comprising a rigidly-mounted base frame 45 (also referred
to as a first framework), and a slidably-mounted frame 46 (also referred
to as a second framework). The rigidly-mounted base frame 45 is
configured for connection to the bottom-link arms 318 and top-link arm
324 of mobile machinery, such as the tractor 38 (see FIG. 1a).
Connections from the tractor to the rigidly-mounted base frame 45 occur
at the top link attachment 66 and at the two bottom-link attachment 68.
The rigidly-mounted base frame 45, also referred to as the first frame,
has at least two parallel, vertically spaced apart, laterally extending
rails. In the version shown in FIG. 5 and FIG. 6, the first frame 45
comprises four tiered horizontal longitudinal frame member rails 48, 49,
50, 51, which can be solid or hollow and any suitable shape in
cross-section, rigidly connected at the ends to at least two vertical
support members, also referred to as studs, and capable of being
removably secured to the three-point hitch of the tractor. Preferably in
the design of the rigidly-mounted base frame there are at least two upper
and two lower horizontal frame members providing an opening of sufficient
size between the upper and lower horizontal frame members to accommodate
a Power Take Off "PTO" driveline if required for the attached implement.
The PTO opening arraignment is shown in FIG. 7 using a double driver
configuration allowing for the space needed for the PTO driveline to
connect to an implement. FIG. 5 and FIG. 6 show three upper and three
lower horizontal frame members for the rigidly-mounted base frame showing
the rigidly-mounted base frame with six horizontal longitudinal aligned
frame members, wherein frame member 47 (also referred to as upper cross
beam), 48 and 49 are in an upper position and frame members 50, 51, 52
(member 52 is also referred to as lower cross beam), are in a lower
positions, and four vertical frame members. Frame members 53 and 54, also
referred to as studs, are positioned to one side of the rigidly-mounted
base frame and frame members 55 and 56 are positioned to the opposing
side of the rigidly-mounted base frame. Members 53, 54, 55, and 56 are
also referred to as studs. Members 48, 49, 50, and 51 are also referred
to as rails. The laterally adjustable three-point hitch implement
attachment apparatus 40 has square shaped horizontal sliding-frame
members 57,58,59,60 (also referred to as sleeves) and square shaped
horizontal rigid-frame members 47,48,49,50,51,52 oriented in a diamond
shape with all sides placed at forty-five degree angles as compared to a
horizontal plane. By square shaped this is with regard to a vertical
cross section and preferably they are oriented with a corner facing
upwardly.
[0304] The slidable-mounted frame 46 comprises at least two horizontal
longitudinally aligned hollow frame member tubes securely and sturdily
connected at the ends with at least two vertical frame members forming a
generally rectangular sturdy frame that is transversely and
slidably-mounted on at least two horizontal longitudinal frame members,
bars or rails of the rigidly-mounted base frame 45 enabling the
slidable-mounted frame 46 to travel transversely, also referred to as
laterally, across from one side to the other side of the rigidly-mounted
base frame 45. FIG. 5 shows two upper and two lower horizontal hollow
frame members for the slidably-mounted frame, wherein frame members 57
and 58 are in the upper positions and frame members 59 and 60 are in the
lower positions. They slide on the rails of the base frame 45. Shown in
FIG. 5 are four vertical frame members, two vertical frame members 61 and
62 are positioned to one side and frame members 63 and 64 are positioned
to the opposing side. Frame members 61-64 are also referred to as posts.
Four hollow horizontal slidable-mounted frame members as opposed to two
hollow horizontal slidable-mounted frame members can provide a greater
load carrying capacity of the connecting apparatus.
[0305] The upper horizontal rigidly-mounted base frame members 48 and 49
pass thru the upper slidable-mounted frame members 57 and 58. The lower
horizontal rigidly-mounted base frame members 50 and 51 pass thru the
lower slidable-mounted frame members 59 and 60. The slidable-mounted
frame 46 is free to laterally move with respect to the rigidly-mounted
base frame 45. All six rigidly-mounted base frame members and all four
slidable-mounted frame members are typically vertically coplanar. While
FIG. 5 and subsequent figures show a frame made from longitudinal members
having a rectangular or square cross-section, it is contemplated that
longitudinal members may be formed having a cylindrical cross-sectional
area such as pipes or solid rods (see FIG. 39b). FIG. 5 and subsequent
figures show the square frame members turned in a diagonal horizontal
position representing a diamond shape, the connecting apparatus would
also work in a similar fashion with the frame members turned in the
square position with the bottom and top of the frame members situated in
a horizontal squared position (see FIG. 39a) as opposed to a forty-five
degree diamond slanted position when compared to a horizontal plane.
[0306] As depicted in subsequent drawings, (see FIGS. 13, 14, 15, 16) a
lighter more economical version of the connecting apparatus 40 as
depicted in FIG. 5 can be configured with only two hollow horizontal
frame members included in the slidably-mounted frame 46 and only four
horizontal frame members included in the rigidly-mounted base frame 45.
(see FIGS. 13, 14, 15, 16) In addition to the connecting apparatus as
depicted in FIG. 5, a larger stronger version of the connecting apparatus
can be configured by increasing the number of horizontal frame members
included in the slidably-mounted frame to six or more (not shown) and
increasing number of horizontal frame members in the rigidly-mounted
frame to eight or more. (not shown) Also in addition to adding horizontal
and vertical frame members to gain more strength and weight carrying
capacity of the connecting apparatus, using a stronger or greater
diameter and thickness of the metal used in all of the frame members will
achieve a greater weigh carrying and working capacity. For great weight
carrying and working capacity of the connecting apparatus, all of the
rigidly-mounted base frame horizontal frame members can be constructed of
solid steel bars.
[0307] FIG. 6 shows a single location of top-link attachment plate 66 and
two locations of bottom-link attachment plates 68 located on the
rigidly-mounted frame 45, which are for attachment to the tractor
top-link and bottom-link points, respectively, of the three-point hitch.
Four horizontal sliding-frame members or sleeves are shown. Pushing or
pulling means such as a hydraulic actuator and cylinder, electric
actuator and cylinder, pneumatic actuator and cylinder, other positioning
devices, chain, cable, belt or combinations thereof are provided for
moving the slidable-mounted frame 46 laterally and parallel to the
rigidly-mounted frame 45.
[0308] For example, a single hydraulic driver 80 is mounted for the
lateral adjustments of the sliding-frame 46. The hydraulic driver 80
provides lateral movement of the slidably-mounted frame 46 across the
rigidly-mounted base frame 45. The slidably-mounted frame 46 is free to
slide laterally with respect to the base frame 45. The left-right
movement and position of slidably-mounted frame 46 is changed by at least
one hydraulic driver 80 comprising a housing 82 and a piston 83, or
optionally more than one driver, such as two hydraulic drivers 80 (see
FIG. 7). Typically, the driver has an internal stop for limiting the
lateral movement of the slidably-mounted frame 46. The hydraulic driver
is connected between the rigidly-mounted base frame 45 and the
slidably-mounted frame 46. The cylinder housing 82 of the hydraulic
driver 80 is removably attached at one end to a bracket 90 with a pin and
clip and the bracket 90 is connected to bracket 92b which is connected to
the rigidly-mounted base frame 45 at vertical frame member 56. The piston
83 of the hydraulic driver 80 is removably attached to a bracket 89 with
a pin and clip and the bracket 89 is connected to a bracket 94b which is
connected to the slidably-mounted frame 46 at the vertical frame member
61. In this configuration, when the piston 83 of the hydraulic driver 80
moves out of the housing 82, the slidably-mounted frame 46 is caused to
slide away from the bracket 90 of the rigidly-mounted base frame 45. When
the piston 83 of the hydraulic driver 80 moves back into housing 82, the
slidably-mounted frame 46 is caused to move closer to the bracket 90 of
the rigidly-mounted base frame 45. The hydraulic cylinder housing 82 has
two hydraulic flexible lines 85 attached which in turn can be attached to
a tractor manual hydraulic control valve 236 and the automated hydraulic
control valve 238. The driver 80 can be operated manually or
automatically.
[0309] The single hydraulic cylinder 80 is mounted in a centered location
between the top and bottom of the sliding-frame 46 for lateral adjustment
of the sliding-frame 46. The single hydraulic cylinder centered design
can be used when a Power Take Off "PTO" driveline is not required for the
implement that is attached to the connection apparatus as this centered
single hydraulic cylinder position would obstruct the pathway 98 of a PTO
driveline (see FIG. 7) as it is connected between the tractor PTO shaft
and the implement to be attached to the connection apparatus.
[0310] The driver typically has static loading capacity, meaning that when
the driver stops and reaches a predetermined adjustment point, the driver
essentially locks in place and can support a load that is either pulling
or pushing on the driver. Typically, in an agricultural tractor
application, the tractor hydraulic system control valves and hydraulic
cylinders are valved for a static loading capacity. Typical electric
linear actuators that are screw or gear driven generally have a static
loading capacity or an electro-mechanical brake added to provide improved
static loading capacity.
[0311] Preferably hydraulic drivers are used as compared to electric,
sprocket and chain drives, pneumatic drives and electro-magnetic drives.
Hydraulic actuators are rugged and suited for high-force applications.
They can produce forces 25 times greater than pneumatic cylinders of
equal size. They also operate in pressures of up to 4,000 psi.
[0312] Electric motor actuator drives are weak and usually expensive
compared to hydraulic cylinder movement applications. Electrical
actuators can be used, because they have fewer component parts and can
provide precision-control positioning. An example of the range of
accuracy is +/-0.0003 in. and a repeatability of less than 0.00004 in.
Their setups are scalable for any purpose or force requirement, and are
quiet, smooth, and repeatable. The initial unit cost of an electrical
actuator is higher than that of pneumatic and hydraulic actuators.
[0313] Sprocket and chain drives can be used, but they have slack between
the parts causing less precise movement when compared to a hydraulic
cylinder positioning system.
[0314] Pneumatic cylinder drives can be used but they have limited
position control Electro-magnetic actuators such as linear motor
actuators, although possible in this application, generally do not
possess sufficient force capacity for linear movement. Linear motor
actuators do have the advantage of being able to be sealed very easily
against moisture and corrosion allowing for a long service life. As
technology advances, electro-magnetic actuators may be a preferred choice
in many applications. Mechanical actuator means only of controlling the
driver may be useful in a limited number of applications using mobile
machinery.
[0315] Manual operational control of the hydraulic or electric driver can
be preferred in some applications while using the connecting apparatus. A
switch switching between manual and automatic control of the driver can
be provided along with a manual control valve or switch. One instance
when manual control of the driver may be utilized is when then mobile
machine operator is attaching or removing implements from the connecting
apparatus. The manually operated valve or switch would provide manual
lateral positioning of the connecting apparatus slidable frame for hookup
of an implement. Another instance where manual operation of the driver
may be utilized is when the mobile machine operator has no automatic
guidance system setup for use or the mobile machine operator simply
prefers the manual operation of the driver in certain applications.
[0316] Also shown in FIG. 6 is the rear face of the double wrap-around
bracket clamps 78, which are used for the opposing implement side
connection.
[0317] Attachment plates 66 are mounted on the tractor facing side of the
rigidly-mounted base frame 45 top horizontal frame member 47 for
connection of the top-link arm 324 (see FIG. 1c) to the tractor top-link
attachment brackets 340 (see FIG. 3). Two attachment plates 68 are
mounted on the tractor facing side of the rigidly-mounted base frame 45
bottom horizontal frame member 52 for hookup of the tractor bottom-link
arms 318 (see FIG. 3) to the connecting apparatus. Top-link attachment
plates 66 includes two vertical parallel plates or flanges defining a
bracket with coaxial aligned thorough holes projecting outward or upward
from the surface of the rigidly-mounted base frame top horizontal member
47 which provides for connecting a top-link arm 324 (see FIG. 1b) to the
tractor. Bottom-link attachment plates 68 include two vertical parallel
plates or flanges defining a bracket with coaxial aligned thorough holes
projecting outward or outward and upward from the surface of the
rigidly-mounted base frame bottom horizontal member 52 which provides for
connecting the two bottom-link arms 318 (see FIG. 3) of the tractor to
the rigidly-mounted base frame 45.
[0318] At least four grease fittings 74 for each horizontal frame member
of the slidable-mounted frame 46 are provided to lubricate the sliding
action of the slidable-mounted frame 46 upon the rigidly mounted frame
45. Optimally, sixteen or more grease fittings are provided for each
horizontal frame member of the slidably-mounted frame 46 for complete
coverage of lubricant between the two frames. Grease fittings 74 are
shown mounted on the slidable-mounted frame 46 screwed into threaded
holes or fittings on all sliding horizontal frame members of the
sliding-frame 46.
[0319] Shown in FIG. 6 are viewable rigid-frame alignment marks 70, also
referred to as positioning indicia, located on the upper rigid-frame
horizontal frame member 47 marking the edge of the sliding-frame when the
sliding-frame is centered on the rigid frame, the rigid-frame alignment
marks 70 located on the lower rigid-frame horizontal frame member 52
marking the edge of the sliding-frame when the sliding-frame is centered
on the rigid frame. A rigid-frame alignment mark 72, also referred to as
positioning indicia, is located on the lower rigid-frame horizontal frame
member 52 for marking the center of the sliding-frame when the
sliding-frame is centered on the rigid-frame. This allows centering of
the slidable frame. For the upper rigid-frame horizontal frame member 47,
the rigid-frame top-link attachment plates 66 serves as a center mark.
The hydraulic cylinder 80 length and rigidly-mounted frame section 45
width can be altered depending on the length of lateral movement required
of the sliding-frame section 46.
[0320] FIG. 6 shows the hydraulic lines 85 connected between the hydraulic
driver 80 and both the manual hydraulic control valve 236 and the
automatic hydraulic control valve 238. FIG. 7 show hydraulic lines 87
connected between a hydraulic flow divider 88 and both the manual
hydraulic control valve 236 and the automatic hydraulic control valve
238. FIG. 6 and FIG. 7 show hydraulic lines 87a connected between the
manual hydraulic control valve 236 and a hydraulic valve selector switch
240. Hydraulic lines 87b are connected between the automatic hydraulic
control valve 238 and the hydraulic valve selector switch 240. Hydraulic
lines 87c are connected between the hydraulic valve selector switch 240
and the hydraulic pump 81. Hydraulic power receptacle 242 comprising dual
quick connect couplers serve as the hydraulic power receptacle and
connect and disconnect means for the hydraulic lines when attaching or
removing the first connecting apparatus 40 from the tractor three-point
hitch.
[0321] With reference to FIG. 7, a laser receiver and a GPS antenna and
receiver module 110e is also shown mounted on the top bar 100a. A choice
can be made as to which receiver and controller is used depending on the
application. Both receivers normally are not used at the same time. A GPS
controller can be required to be matched to the GPS antenna and receiver
module 110e; likewise, a laser controller can be required to be matched
to the laser receiver 110. Each receiver receives a signal from a
transmitter and then relays a signal that can be digital or analog or
other to the controller 150 through signal wire 110d or 110f. A data
entry monitor 150b can be provided if required to enter data to the
controller such as in the case of the GPS controller. Data wire 150c is
connected from the data entry monitor 150b to the controller 150. (see
FIGS. 6 and 7) The controller 150 sends a signal 150a to the automatic
hydraulic control valve 238. (see FIGS. 6 and 7) In the instance where an
electric actuator is used for the driver 80, FIG. 4b shows the
configuration of the electrical components for the operation of the
driver 80.
[0322] FIG. 7 shows a double hydraulic cylinder providing lateral movement
of the slidably-mounted frame 46 across the rigidly-mounted base frame
45. The double hydraulic cylinder design can be used when a Power Take
Off ("PTO") driveline is required for the implement that is attached to
the connection apparatus, as this double hydraulic cylinder design
normally does not obstruct the pathway of a PTO driveline as it is
connected between the tractor PTO shaft and the implement to be attached
to the connection apparatus. In addition, heavy loads that may be mounted
on the connection apparatus can benefit from the double hydraulic
cylinder design by spreading out the push-pull force of the hydraulic
cylinders to two locations of the sliding-frame 46 instead of one
location. The slidably-mounted frame 46 is free to slide laterally with
respect to the base frame 45.
[0323] The left-right movement and position of slidably-mounted frame 46
is controlled by two hydraulic drivers 80. Each hydraulic driver is
connected between the rigidly-mounted base frame 45 and the second
slidably-mounted frame 46. The housing 82 (see FIG. 6) of the top
hydraulic cylinder 80 is connected at one end to the bracket 90 which is
connected to brackets 92a which are connected to the rigidly-mounted base
frame 45 at vertical frame member 56. The piston 83 of the top hydraulic
driver 80 is connected at one end to the bracket 89 which is connected to
bracket 94a which is connected to the slidably-mounted frame 46 at
vertical frame member 61. The housing 82 of the bottom hydraulic driver
80 is connected at one end to the bracket 90 which is connected to
bracket 92c which is connected to the rigidly-mounted base frame 45 at
vertical frame member 56. The piston 83 of the bottom hydraulic driver 80
is connected at one end to the bracket 89 which is connected to bracket
94c which is connected to the slidably-mounted frame 46 at vertical frame
member 61. In this double hydraulic driver configuration, when the
pistons 83 of the hydraulic drivers 80 moves out of hydraulic housing,
the slidably-mounted frame 46 is caused to slide away from the bracket 90
of the base frame 45. When the pistons 83 of the hydraulic driver 80
moves back into the housings 82, slidably-mounted frame 46 is caused to
move closer to brackets 90 of the base frame 45. In the double hydraulic
cylinder configuration, the hydraulic fluid flow divider 88 is utilized
to provide even distribution of hydraulic fluid to each hydraulic driver
80, causing both hydraulic drivers 80 to be synchronized with each other
while moving in parallel to provide the lateral movement of the
slidably-mounted frame 46 with respect to the rigidly-mounted base frame
45. Hydraulic lines 86 are disposed between each hydraulic cylinder 80
and the hydraulic fluid flow divider 88 for even fluid distribution to
the hydraulic cylinders 80 while hydraulic lines 87 are disposed between
the hydraulic fluid flow divider 88 and the hydraulic control valve
normally equipped on a tractor carrying the connecting apparatus. The
double hydraulic cylinder configuration can be helpful in moving the
slidably-mounted frame 46 when the implement to be carried by the
connecting apparatus is of the larger and heavier nature.
[0324] With reference to FIGS. 7 and 8, a top-bar first bar 100a is
rigidly attached to the slidably-mounted frame section 46 with attachment
legs 101. The top-bar first bar 100a supports (i) a laterally adjustably
positioned laser receiver 110 or a GPS antenna and receiver module 110e
provided with an adjustable holding bracket 108 for supporting a GPS or a
laser guidance system, (ii) an LED light fixture 118, and (iii) mounted
camera housing 112 comprising two cameras 114 and 116 focused rearwardly
and downwardly, respectively, being mounted on a slidable bar 104 for
lateral adjustment. The separate viewing cameras 114 and 116 are enclosed
in the camera housing 112. Top-bar 100a has a top-bar plate 100c for the
mounting of the GPS antenna and receiver module 110e with dual antennas
(see FIG. 11). The slidably-mounted frame 46 horizontal frame members and
the top-bar first bar 100a have indicia markings, also referred to as
positioning indicia, laid down in inches or millimeters thereon, to
provide useful adjustment marks. Laser receiver 110 has a left alignment
indicator 110a, center alignment indicator 110b and a right alignment
indicator 110c. The top-bar first bar 100a extends laterally beyond the
slidable frame 46 as is needed. A position-sensor 151 is attached to
the-top-bar mounting leg 101. A position-sensor bar 151a is attached to
the rigid-frame horizontal frame member 47 with position-sensor bar
attachment brackets 152, with position sensor electrical wires 152a
extending from position sensor bar 151a.
[0325] With reference to FIG. 7, optionally the position signal receiver
110 or 110e, such as a GPS or laser signal receiver, supported by the
slidable second framework, can determine the position of slidable second
framework, and can provide a position signal through signal wires 110d or
110f the controller 150. The controller 150 is adapted to control the
driver 80 for keeping the implement on track via the controller output
signal 150a to the automated hydraulic valve that controls the driver 80.
A suitable programmed controller 150 that can provide output signals can
be obtained from by Trimble of Sunnyvale, Calif. for either the laser or
GPS system.
[0326] FIG. 8 is a perspective view of the implement-facing side of the
connecting apparatus 40. The slidably-mounted frame 46 provides
connection means for most three-point hitch implements in the
agricultural and earth excavating fields, such as bed shapers, seed
planters, plant transplanters, cultivators, weeders, sprayers, rippers,
box scrapers and the like. The slidably-mounted frame 46 is fitted with
two double-frame member wrap around bracket clamps 78, which are mounted
to the slidably-mounted horizontal frame sleeves 59 and 60. Sliding-frame
bottom-link mounting arms 132 attach to two double wrap-around bracket
clamps 78 which protrude out towards the implement to be attached.
Sliding-frame bottom-link quick-hitch slip-on housing 135, as described
in U.S. Pat. No. 7,059,419, attach and secure over the sliding-frame
bottom-link mounting arms 132. (see FIG. 23) The bottom-link attachment
points are normally spaced between 20 and 36 inches apart in a centered
location on the slidably-mounted frame 46 and located near the horizontal
plane of sliding-frame member 60. The slidably-mounted frame 46 is also
fitted with a top-link quick hitch attachment point attached to the
double wrap-around bracket clamp 78 which is mounted to slidably-mounted
horizontal frame members 57 and 58. The top-link quick hitch attachment
point is normally horizontally centered between left and right on the
slidably-mounted frame 46 and adjustably located near or between the
horizontal planes of sliding-frame members 57 and 58. The two
sliding-frame bottom-link attachment hooks 136 and latching mechanism 139
combined with the sliding-frame top-link hook 130 provides for quick and
easy attachment of a three-point hitch implement such as the carry-all
300 (see FIG. 2) and serve as connectors.
[0327] The rigid-frame alignment marks 70 are located on the top
rigid-frame horizontal frame member 47 marking the edge of the
sliding-frame when the sliding-frame is centered on the rigid frame. The
rigid-frame alignment mark 72 located on the top rigid-frame horizontal
frame member 47 marks the center of the sliding-frame when the
sliding-frame is centered on the rigid frame. Rigid-frame alignment marks
70 located on the bottom rigid-frame horizontal frame member 52 mark the
edge of the sliding-frame when the sliding-frame is centered on the rigid
frame. The rigid-frame alignment mark 72 located on the bottom
rigid-frame horizontal frame member 52 marks the center of the
sliding-frame when the sliding-frame is centered on the rigid frame.
[0328] With reference to FIGS. 14 and 23, there is shown the sliding-frame
bottom-link mounting arms 132 and rotatable ball joints 134 that are
normally located on the end of a tractor's bottom-link arms 318. (see
FIG. 1c) Serving as the bottom connector on the sliding frame is a
quick-hitch slip on housing 135 as described in U.S. Pat. No. 7,059,419.
Connector 135 securely mounts over the sliding-frame bottom-link mounting
arms 132. The sliding-frame bottom-link quick hitch slip on housing 135
and latching mechanism 139 allow for a quick hookup and release of the
implement from the tractor bottom-link arms. Direct hookup of
sliding-frame bottom-link mounting arms 132 (see FIG. 14) to the
implement is a more cumbersome hookup procedure as compared to the quick
hitch style of implement hookup, although this direct sliding-frame
bottom-link mounting arm 132 hookup may provide a more secure and tighter
fit to the implement in very precise method of use applications. The
quick hitch slip on housing 135, U.S. Pat. No. 7,059,419 includes a hook
means 136 open at the top and a manually or spring operated latch 139 as
shown in a close up view (see FIG. 23). This close-up view shows the slip
on housing slips over the sliding-frame bottom-link mounting arm 132 and
is then held in place by a pin which enters the slip on housing 135 and
then extends through the rotatable socket and ball with axial hole of arm
132. Additional securing and adjustment screws are located around the
slip on housing 135 for fine adjustments and a tight level fit.
[0329] With reference to FIG. 8, the top-link quick hitch attachment
comprises a top-link channel back spacer 119 to vertically align the
top-link quick hitch attachment points with the sliding-frame bottom-link
quick hitch attachment points 136. An additional top-link bracket spacer
121 is attached between the double wrap around bracket clamp 78 and the
top-link channel back spacer 119 to provide access to the double
wrap-around bracket clamp 78 mounting bolts. Attached to the top-link
channel back spacer 119 is an adjustable mounting channel 122. Bolted
into the adjustable mounting channel 122 is a sliding-frame top-link hook
and stop bar 130 top-link channel side spacers 120 inserted and bolted
through. The sliding-frame top-link hook 130 generally is deeper and
longer than the sliding-frame bottom-link quick-hitch hook and stop bar
136, the sliding-frame top-link hook 130 does not generally perform
lifting functions of the attached implements, the sliding-frame top-link
hook 130 hooks under and then up to catch the top-link hookup connection
on the implement 312 (see FIG. 2) and holds the implement in place and
allows the adjustment of tilting forward and backwards performed by the
tractor mounted top-link arm 324. (see FIG. 1c) Top-link arm 324 is
mounted to the tractor at location 340 (see FIG. 3) and to the connecting
apparatus, and in many applications can be a double action hydraulic
cylinder performing tilting adjustments for the attached implement.
[0330] FIG. 9 is a perspective view of the implement facing side of the
connecting apparatus, showing the sliding-frame bottom-link housing 138
attached to the adjustable mounting channel 122 which traverses the four
horizontal frame members 57, 58, 59, 60 of the sliding-frame 46. The
adjustable mounting channel 122 attaches to two double wrap-around
bracket clamps 78 of the sliding-frame 46. The adjustable mounting
channel 122 in this configuration can provide additional bottom-link
higher or lower adjustments and added strength to the sliding-frame 46
while allowing space for an implement PTO driveline to pass through the
connecting apparatus from the implement being carried to the tractor PTO
shaft. A sliding-frame bottom-link quick-hitch bolt-on housing 138 can be
provided in place of the sliding-frame bottom-link quick-hitch slip-on
housing 135, U.S. Pat. No. 7,059,419. The sliding-frame bottom-link
quick-hitch bolt-on housing 138 can be a more stable attachment for the
bottom-link connection point to the implement of the connecting apparatus
as compared to the sliding-frame bottom-link quick-hitch slip-on housing
135. In the alternative for connecting an implement to the connecting
apparatus, the sliding-frame bottom-link mounting arm and ball socket,
bolt-on 133, as shown in FIG. 20, can be used in place of the
sliding-frame bottom-link quick-hitch bolt-on housing 138 to provide a
more stable attachment of the implement to the connecting apparatus. The
position-sensor 151 sliding-frame mounted is attached to a top-bar
mounting leg 101.
[0331] The position-sensor bar 151a is rigid-frame mounted, and is
attached to the top rigid-frame horizontal frame member 47 with
position-sensor bar attachment brackets 152. Position sensor electrical
wires 152b and the position sensor bar electrical wires 152a extend from
both position sensor 151 and position sensor bar 151a to provide the
conductors for the position sensor signal 151b and the position sensor
bar signal 151c. Optionally a wireless connection can be used. The
position sensor 151 and the position sensor bar 151a can send a visual
screen signal 153e for an operator's viewable positioning screen 153d for
the tractor operator to view the position of the slidable-frame 46
position as related to the rigid-frame 45 position while looking forward
and away from the rear three-point hitch mounted connecting apparatus.
This allows the tractor operator to reposition the rigid-frame 45 by
repositioning the tractor using the tractors steering if the tractor is
diverging from the prescribed path. Auto-steering of the tractor can also
be utilized by configuring the position sensor 151 and the position
sensor bar 151a with an automated auto-steer controller 153 utilizing an
auto-steer controller signal 153a sent to the auto-steer device 153b to
control the steering of the tractor. The auto-steer controller can be
equipped with an auto-steer controller on-off switch 153c to allow the
tractor operator to manually steer the tractor when necessary.
[0332] In the instance the auto-steer function is utilized, and in the
instance the tractor is to be steered in a straight line only by the
auto-steer function, mounting the connecting apparatus on the rear
three-point hitch of a front wheel steered tractor is sufficient to keep
the tractor in a straight line. In the instance a front wheel steered
tractor is required to auto-steer in a path that is not a straight line
such as turns, the connecting apparatus 40 can be mounted on the front of
the tractor for precise steering along a predetermined path. In this
instance the present apparatus 40 can be mounted on the front three-point
hitch of the tractor and another apparatus 40 can be mounted on the rear
three-point hitch of the tractor depending on the application and
implements being used. In the alternative to mounting the apparatus 40 on
the front of a front wheel steered tractor in a situation where the
predetermined path follows turns and the apparatus 40 is required to be
mounted on the rear three-point hitch of the tractor, a separate auto
steer device can be mounted on the front of the tractor to achieve
sufficient auto-steering results in a predetermined path following turns.
[0333] Optionally for mobile machinery equipped with an auto-steering
system 153 and 153b, such as those provided by Trimble of Sunnyvale,
Calif., the position sensor 151 sensing the position of the second
framework relative to the first framework, can use the auto-steer system
for automatically adjusting the position of the mobile machinery based on
the sensed position of the second framework relative to the first
framework. Current auto-steering devices work by either controlling the
hydraulic fluid of the mobile machinery hydraulic steering system or
controlling the mechanical steering wheel of the mobile machinery.
[0334] FIG. 10 is a perspective view of the implement facing side of the
connecting apparatus 40, showing the adjustable mounting channel 122
attached to the double wrap around bracket clamp 78 comprising a two
horizontal frame member channel mounting configuration of the
sliding-frame for the bottom-link connections to the implement. This
configuration expands the pathway 98 for a PTO driveline as compared to
FIG. 9. Grease fittings, also referred to as great joints 74, are shown.
Two viewable gauges level measurement 146 are secured to a gauge mounting
plate 145 mounted on the top and at each end of the rigid-frame top
horizontal frame member 47, and situated to be viewed from the rear of
the tractor such as from the tractor seat area allowing the tractor
operator to view and adjust the connecting apparatus accordingly. Two
viewable gauges plumb measurement 147 are mounted on the side, near the
top of each rigid-frame vertical frame member 53 and 56. One auto-sensor
gauge level measurement 148 is mounted on one of the gauge mounting
plates 145 situated on the rigid-frame horizontal frame member 47. One
auto-sensor gauge plumb measurement 149 is mounted on the side, near the
top of rigid-frame vertical frame member 53. The auto-sensor devices can
automate the level and plumb positions of the connecting apparatus
utilizing the tractor installed hydraulic positioning of the tractors
three-point hitch. This automated leveling and plumbing of the connecting
apparatus requires the tractor three-point hitch to accommodate
controlled hydraulic cylinders at the top-link arm 324 and on at least
one of the bottom-link arms 318.
[0335] A bottom-bar 140 is mounted on the bottom of the slidable-mounted
frame 46 and below the sliding-frame bottom-link 138, and below a double
wrap-around bracket clamp 78 being securely fastened to the
slidable-mounted frame 46 with bottom-bar mounting legs 142. Bottom-bar
sensor or cameras 144 are securely mounted to the underside of the
bottom-bar 140, in the case of sensors, for the detection of electronic
signals transmitted from an underground buried cable in which the
slidable-mounted frame 46 adjusts laterally to follow the path of the
signal transmitted from the underground buried cable. In the case of
cameras, recognition computer software can be used to detect the position
of crops or other items like line markers or shapes to adjust the
slidably-mounted frame 46 in position. Bottom-bar signal wire 144a can
transmit the signal to controller 150 (see FIG. 6) utilizing the same
configuration of controller and related equipment as shown in FIG. 6.
Bottom-bar 140 is extendable horizontally past the ends of the
rigidly-mounted frame 45 to accommodate a particular purpose and also be
repositioned if needed on a higher plane on the slidable-mounted frame
46.
[0336] FIG. 11 is a perspective view of the implement facing side of the
connecting apparatus, showing a four-point implement connection design in
a double-link top-link configuration 155 of the sliding-frame 46 as it
connects to a four-point bracketed implement. Two sliding-frame
bottom-link quick hitch attachments with bolt-on housings 138 and two
sliding-frame top-link hook and stop bar 130 (see FIG. 12) attachments
are shown. The sliding-frame 46 bottom-link quick-hitch bolt-on housings
138 are attached to the adjustable mounting channel 122 which traverses
four horizontal frame members 57, 58, 59, 60 of the sliding-frame 46. The

the horizontal frame members are sliding members 57 and 60 and the
remaining two horizontal frame members are support members 156 and 158 in
a diamond position to accommodate the double wrap-around bracket clamps
78. In the case of a slightly reduced weight load on the connecting
apparatus, four horizontal sliding-frame members may not be needed.
Consequently, two horizontal sliding-frame members which slide on the
rigidly-mounted base frame 45 horizontal members are provided, while two
additional sliding-frame horizontal members do not contact the
rigidly-mounted base frame and thus are utilized as support members only.
Stand mounting holes 164 are positioned between the upper and lowers
rigid-mounted base frame members. Implement positioning sensors or
cameras 154 are mounted to the implement facing side bottom-links and the
implement facing side top link. Implement positioning sensors or cameras
154 can be utilized and wired to controller 150 (see FIG. 6) for
assisting in the connection of the implements to the connecting apparatus
by adjusting the position of the sliding-frame to align the first
connection apparatus 40 implement facing side bottom and top links with
the implement bottom and top link attachment pins or hardware.
[0339] FIG. 14 is a perspective view showing the connecting apparatus of
FIG. 13, showing the two sliding-mounted frame bottom-link connections as
sliding-frame bottom-link mounting arm and ball sockets 132 without the
bottom-link quick-hitch slip-on housing.
[0340] FIG. 15 is a perspective view showing the connecting apparatus of
FIG. 14, showing the two sliding-frame bottom-link connections as
bottom-link mounting arm and ball sockets extended length 137 without the
sliding-frame bottom-link quick-hitch slip-on housings 135 attached
thereon. Shown is a four-point implement connection design in the
double-link top-link configuration 155. Sliding-frame bottom-link

second connecting apparatus 41 in a more compact-design as compared to
the previously disclosed upright-design 40 wherein the top and bottom
rigidly-mounted horizontal frame members 47 and 52 as depicted in FIG. 5
are moved forward and level with the adjoining rigidly-mounted horizontal
frame members 48 and 51. The new forwardly mounted rigidly-mounted frame
members are numbered 172 for the top member and 174 for the bottom member
for the purpose of this compact-design 41 as shown in FIG. 17 and FIG.
18. Rigid-frame top-link attachment 66 is attached to rigidly-mounted
frame member 172 and two rigid-frame member bottom-link attachments 68
are connected to rigidly-mounted frame member 174. The compact-design 41
of the connecting apparatus has shortened rigid-frame vertical studs 180,
182, 184, 186 with two forward mounted rigid-frame vertical members 176
and 178. Four rigid-frame braces 188 between forward mounted horizontal
frame member 172 and rigid-mounted frame member 48 are shown. Two of the
four rigid-frame braces 188 between forward mounted horizontal frame
member 174 and rigid-mounted frame member 51 are shown. Rigid-frame
braces 188 can be installed on these two members to mirror the frame
braces for the top forward horizontal rigid-frame bar 172. The
compact-design 41 of the connecting apparatus provides a lower elevation
plane of the implement facing side sliding-frame bottom-link connections
136 and the sliding-frame top-link 130 connection as compared to the
upright-design 40 of the connecting apparatus. The compact-design 41
disposes the rigidly-mounted frame top-link attachment 66 on or near the
same horizontal plane as the sliding-frame top-link connection 130 and
also disposes the rigidly-mounted frame bottom-link attachment 68 on or
near the same horizontal plane as the sliding-frame bottom-link
connection 136, allowing for the attachment of lower elevated implement
bottom-link connection points 314 and top-link connections 312 when
compared to the upright-design 40 of the connecting apparatus. The
compact-design 41 can be utilized on smaller tractors with lighter
weighted implements to be carried and used.
[0343] FIG. 18 is a perspective view showing the connecting apparatus of
FIG. 17 with a stand 165 attached to the outer vertical rigid frame

[0344] FIG. 19 is a close-up perspective view of the implement-facing side
of the sliding-frame bottom-link quick-hitch style connection point in a
bolt-on configuration to the adjustable mounting channel 122. Instead of
a sliding-frame bottom-link quick-hitch slip-on housing 135 (see FIG. 8),
a sliding-frame bottom-link quick-hitch bolt-on connector is used, the
connector comprising a housing 138 with latch and lever 139, mounted to
the adjustable mounting channel 122. The connector includes a hook and
stop bar 136. Channel mounting bolt and nut 128 attaches the
sliding-frame quick-hitch bolt-on housing 138 with the bolt passing

[0345] FIG. 19a shows attachment support bases 75 in place of triple wrap
around bracket clamps 79. Attachment support bases 75 are attached to the
sliding frame horizontal frame members in a manner such as welding them
in place with weld connections 73 shown on one section of the bracket to
be duplicated on the remaining sections of the bracket where the bracket
intersects the horizontal frame members of the sliding frame 46.
Attachment support bases 75 can replace the triple wrap around bracket
clamps 79 and also can replace double wrap around bracket clamps 78 (see
FIG. 10) and single wrap around bracket clamps 76 (see FIG. 16).
Currently many of the agricultural implement bottom link and top link
positions are being standardized to simplify quick hitch hookup
arrangements as built into many quick hitch adapters which mount on the
tractors three-point hitches. This standardization eliminates the need to
adjust the bottom link and top link positions on an apparatus such as the
connecting apparatus 40. In the above stated case of standardization,
attachment support bases 75 would be appropriate to mount to the
connecting apparatus and attached in a fixedly attachment such as metal
welding.
[0346] FIG. 20 is a close-up perspective view of the implement-facing side

[0350] FIG. 24 is a perspective view of an Carry-All implement 300 with a
four-point hitch connection point configuration comprising two
bottom-link connection points 195 and two top-link connection points 192.
Although four-point connections of implements to agricultural or
excavating tractors are not commonly in use, using the connecting
apparatus to carry a four-point attached implement can have a positive
effect on the stability of the implement as the implement is attached and
carried by the sliding frame of the connecting apparatus. The connecting
apparatus being attached to the agricultural or excavation tractor in a
three-point attachment configuration preserves the three-point mounting
advantages of the four-point attached implement. The four-point implement
attachment to the connecting apparatus creates a secure attachment to the
connecting apparatus wherein the implement is a rigidly mounted extension
of the three point attached connecting apparatus.
[0351] FIG. 25 is a perspective view of FIG. 24 that comprises a fifth

configuration for sturdy slidable support between the sliding frame
member 206 and the rigid frame member 204. In this design with bearing
cages 216 installed, the clearance between the outside of the rigid-frame
horizontal frame member 204 and the inside of the hollow sliding-frame
horizontal frame member 206 is approximately 1/4 inch around each of the
four sides.
[0362] FIG. 36 is a close up side view of the sliding-frame horizontal
member sized for sliding plate or bearing clearance 206 slidably-attached
to and surrounding the rigid-frame horizontal member 204 with a roller
cage double raceway ninety degree V style with ball bearings 218 between
the sliding and rigid frames. Shown is the weld seam 210 on the
sliding-frame horizontal member sized for sliding plate or bearing
clearance 206 and the weld seam 208 on the rigid-frame horizontal member
204. Grease joints 74 are shown and inserted into a threaded hole in to
the sliding-frame horizontal member sized for sliding plate or bearing
clearance 206, bearing cap collar 220 fixedly attaches to sliding-frame
member 206 securing roller cage double raceway ninety degree V style with
ball bearings 218 in position. Shown are the roller cage double raceway
ninety degree V style with ball bearings 218 forming a ninety degree
configuration for sturdy slidable support between the sliding frame
member 206 and the rigid frame member 204. In this design with bearing
cages 216 installed, the clearance between the outside of the rigid-frame
horizontal frame member 204 and the inside of the hollow sliding-frame
horizontal frame member 206 is approximately 1/4 inch around each of the
four sides.
[0363] FIG. 37 and FIG. 37c show needle bearing cages 216 mounted to the
interior of sliding-frame horizontal frame sleeves 57,58,59,60 (see FIG.
5). The bottom 50% of the needle bearing cages 216 are normally installed
in the sliding-frame horizontal frame sleeves 57,58,59,60. The top and
the side tops of the sliding-frame horizontal frame sleeves 57,58,59,60
are shown without needle bearing cages 216 installed as to view the
bottom portion of the sliding-frame horizontal frame sleeves 57,58,59,60
as the needle bearing cages 216 are installed. A rigid-frame horizontal
frame rails 48,49,50,51 (see FIG. 5) slide inside of the bearing cages
216 as they are installed in the sliding-frame horizontal frame sleeves
57,58,59,60. The bearing cages 216 length can be measured and installed
half way in from each side of the end of the sliding-frame horizontal
frame member 57,58,59,60. The bearing cages 216 butt to each other in a
tight position in the center of the sliding frame member showing the
bearing cage edges 222, and also butt tightly against the bearing cap
collars 220 attached to each end of the sliding-frame horizontal frame
sleeves 57,58,59,60. Fitting the bearing cages 216 in each side of the
sliding-frame horizontal frame sleeves 57,58,59,60 and measuring, cutting
and installing the bearing cages 216 in half way across the sliding-frame
horizontal frame sleeves 57,58,59,60 allows the connecting apparatus
bearing cages 216 to be replaced without disassembling the rigid mounted
frame section 45 from the slidably-mounted frame section 46. The
slidably-mounted frame section 46 moves all the way to one side of the
rigid mounted frame section 45 to remove the bearing cages 216 from the
opposing side of the sliding-frame horizontal frame sleeves 57,58,59,60
consequently, installing the bearing cages 216 in the same manner.
[0364] FIG. 37a is a perspective view of sliding plates 214 mounted to the
interior of sliding-frame horizontal frame member 57,58,59,60 (see FIG.
5). All four sides of the sliding plates 214 are normally installed in
the sliding-frame horizontal frame member 57,58,59,60.
[0365] FIG. 37b is a perspective view of ball bearing cages and bearings
218 mounted to the interior of sliding-frame horizontal frame member
57,58,59,60 (see FIG. 5). All four sides of the ball bearing cages 218
are normally installed in the sliding-frame horizontal frame member
57,58,59,60.
[0366] FIG. 37c shows a bearing cap collar 220 that holds the needle
bearings cages 216 in place. The bearing cap collar 220 fits snug around
the rigid-frame horizontal frame member 48,49,50,51 (see FIG. 5). The
inside diameter of the bearing cap collar 220 is smaller in diameter than
the sliding-frame horizontal frame member 57,58,59,60 inside diameter to
prevent the needle bearings cages 216 from slipping out of the
sliding-frame horizontal frame member 57,58,59,60. The bearing cap collar
220 is fixedly attached to the sliding-frame horizontal frame member
57,58,59,60 and moves in harmony with said frame member. The thickness of
the bearing cap collar 220 is approximately the combined thickness of the
needle bearing cages 218 and the thickness of one of the sliding-frame
horizontal frame member 57,58,59,60. The bearing cap also can be used
with the versions of FIGS. 37a and 37b.
[0367] FIG. 38 is a perspective view of the tractor facing side of the
connecting apparatus 40 showing the rigidly-mounted frame 45 two
bottom-link attachments 69 in a single vertical plate and stud
configuration that would attach to the tractor bottom-link arms 318 (see
FIG. 1c).
[0368] FIG. 39a is a perspective view of a third connecting apparatus 42
comprising the sliding-frame horizontal frame members and rigid-frame
horizontal frame members in a square shape and installed in a square
position with horizontal and vertical as compared to a horizontal plane.
Top-link attachment 66 shown with brackets matching to the square
horizontal frame member 47 and bottom-link attachments 69 shown with
brackets matching to the square horizontal frame member 52.
[0369] FIG. 39b is a perspective view of a fourth connecting apparatus 43
comprising the sliding-frame horizontal frame members and rigid-frame
horizontal frame members in a round shape. Top-link attachment 66 shown
with brackets matching to the round horizontal frame member 47 and
bottom-link attachments 69 shown with brackets matching to the round
horizontal frame member 52.
[0370] FIG. 39c shows independently controlled wing sections 221 that
attach to the left and right side edges of the rigidly-mounted base frame
45 of the connecting apparatus 40. The wing sections 221 comprise their
own rigidly-mounted base frame 45 and their own slidably-mounted frame
46. All three slidably-mounted frames 46 move independently of each
other. The wing sections 221 can be utilized for carrying lighter duty
implements such as weeders, sprayers, cutters and the like. The wing
sections 221 attach to the three-point attached first connecting
apparatus 40 using a hinge. A piano style hinge 230 can be a suitable
preferred attachment device to utilize for the attachment and pivoting
action of the wing section 221 as connected to the three-point attached
first connecting apparatus 40 left and right side edges. Attachment
hardware 224 and 226 allows for a push pull means such as a hydraulic
cylinder 228 to be mounted on the first connecting apparatus 40 and on
each wing section 221 at the joining corners at the top and bottom of the
three rigidly mounted frame sections 45. Each wing section 221 pivoting
action can be controlled separately apart from the opposing wing section
allowing for individual control of the wing sections. Two hydraulic
cylinders 228 for each wing section 221 can work in tandem using a
hydraulic fluid flow divider 232 between the hydraulic cylinders 228 and
the tractor mounted hydraulic control valve 234. For control of the
slidably mounted frames 46 on each wing sections 221, the wing section
driver 80 can attach directly between the rigidly mounted first frame 45
and the slidably mounted frame 46 using the attachment bracket 89 to the
driver 80 piston arm and the attachment bracket 90 to the driver 80
cylinder housing. The mounted position of the driver 80 on the wing
section differs from the mounting position of the driver 80 on the first
connecting apparatus 40. This difference is the result of the offset
positioning of the wing section 221 slidably-mounted frame 46 as mounted
on the rigidly mounted first frame 45.
[0371] Shown are hydraulic fluid lines 84 from the hydraulic control valve
234 leading to a hydraulic power pump 81, and showing the hydraulic fluid
lines 86 from the hydraulic cylinder 228 to the hydraulic flow divider 88
and showing the hydraulic fluid lines 87 from the hydraulic flow divider
88 to the hydraulic control valve 234.
[0372] For hydraulic or electrically powered devices for driving the
second framework of each wing section 221, such as a hydraulic or
electrically powered cylinder, or for locally pumped fluid, a power
receptacle can be provided on the first framework 45 of the first
connecting apparatus 40, or alternatively on the mobile machinery. The
power receptacle can receive hydraulic fluid or electrical power such as
DC or AC power. For hydraulic or electrically powered devices for driving
the second framework of the first connecting apparatus 40, such as a
hydraulic or electrically powered cylinder, or for locally pumped fluid,
a power receptacle can be provided on the mobile machinery. The power
receptacle can receive power such as hydraulic fluid or DC or AC power.
[0373] Each wing section 221 slidably-mounted frame 46 is mounted in an
offset position on the wing section rigidly-mounted base frame 45 to
allow for the implements attached to the wing section 221 to extend past
the outer edge of the wing section 221, thereby allowing for the
implements attached to the first connecting apparatus 40 to extend
partially across and into the horizontal plane of the wing section 221.
This allows for a cultivating or other farm work path of approximately
sixty feet in width when utilizing three independently moving twenty feet
wide implements. The outer wing section 221 sliding frames 46 move
independently of each other and independently of the first connecting
apparatus 40 sliding frame 46. This independent motion of the sliding
frames allows for a farmer to till, bed-shape and plant crop sections of
the farmland in twenty-foot wide sections using the first connecting
apparatus 40 with attached implements and then mount the lighter weight
wing sections 221 to the first connecting apparatus 40 for the use of
lighter weight implements that can traverse two additional twenty-feet
wide crop sections for less strenuous implement activities such as
weeding, spraying and harvesting. The independent motion of the wing
section 221 sliding frames 46 allows the wing section 221 sliding frame
46 to follow their own particular section of the crop rows as that
particular section of crop rows was planted by a guidance system
independently of the other crop row sections in the sixty-foot total area
covered, variances between the twenty-foot sections of crops rows
throughout the farm occur. Conversely, if a sixty-foot continuous
implement is attached to the first connecting apparatus 40 sliding-frame
46 with no independently controlled wing sections attached and traversing
three twenty foot sections of crop rows and the twenty-foot sections of
crop rows as shaped and planted independently of each other as many
farmers practice currently, the sixty-foot continuous implement may not
align properly with all of the planted crop rows resulting in damaged
crops in a farming procedure such as weeding.
[0374] Functionality of the Related Parts of the Connecting Apparatus:
[0375] The receiver 110 or 110e provides the present position of the
slidable-frame 46 to a GPS controller or laser beam fixedly located in
the field. The GPS controller or laser beam contains the coordinates
describing the desired field position of the implement attached to the
slidable-frame 46 at any one time. If the slidable-frame 46 and the
implement being carried are out of position, the GPS signal or laser
beams signal, after being received by the receiver-110 or 110e, directs
the driver controller 150 to position the driver 80 to keep the implement
which is attached to the connecting apparatus on the prescribed path
using the hydraulic controls on the tractor the apparatus 40. The piston
of the hydraulic cylinder 80 moves the slidable-frame 46 laterally to the
desired position as the tractor moves along.
[0376] A GPS controller is typically a microprocessor that receives GPS
signals, compare the received signal to preprogrammed desired
coordinates, and outputs a signal based on the difference, if any,
between the desired coordinates and the received position. Such GPS
controllers are conventionally used for controlling tractor steering. A
conventional GPS guided steering system for tractors is available from
Trimble of Sunnyvale, Calif. One popular GPS guidance system currently
being used in the agricultural industry is called Real-Time Kinematic
(RTK). RTK systems when combined with earth mounted base stations using
radio or cellular signals relayed to the roving mobile machinery within a
prescribed radius location can achieve horizontal accuracy of <4
centimeters in most conditions. Laser guidance and wire signal guidance
are also viable guidance system technologies available for the control of
the present invention apparatuses. A laser guidance system normally uses
a vertical spinning laser transmitter to be received by the laser
receiver mounted on the apparatus top bar 100a or 100b. The laser
receiver 110 then transmits a signal to the controller 150 which then
controls the driver 80 and the position of the sliding frame 46 of the
controlled apparatus 40. A wire signal guidance system involves multiple
sensors mounted on a bottom bar for a buried wire and on the top bar for
overhead wires. The bottom bar 140 sensor mounted system normally is
utilized in open field agriculture while the top bar 100b mounted sensors
system normally is utilized in greenhouse agricultural applications.
[0377] The lateral position of the sliding frame with respect to the
center line of the base frame and forward movement of the tractor can be
adjusted by causing the pistons of the hydraulic cylinder 32 to extend or
retract.
[0378] The control of the hydraulic cylinder 80 can be implemented in
manual mode by the driver, a second individual, or automatically in
automatic mode by a controller including sensors monitoring the position
of the three-point hitch attached implement with respect to a known
desired position for the implement.
[0379] A system according to this invention comprises the mobile machinery
such as a tractor having a three-point hitch, the connecting apparatus
attached to the mobile machinery with the three attachments; and an
implement attached to the slidable second framework with at least three
connectors. To connect the apparatus to the implement, the implement and
apparatus are placed proximate to each other; the alignment of the
connectors and the hitches are determined, and the alignment is adjusted
by sliding the second framework relative to the first framework.
[0380] After attachment of the implement to the connecting apparatus is
completed, during use of the system, the position of the implement
relative to the mobile machinery is adjusted by the mobile machinery
operator in manual mode or by the signal receiver 110 or 110e and the
driver controller 150 in automatic mode, changing the position of the
second framework to keep the implement on track.
[0381] The driver 80 can be powered hydraulically or electrically. FIG. 4a
is a flow chart depicting a hydraulic driver and related components
suitable for use with the present invention. It utilizes mobile machinery
hydraulic pump 81, which is normally used for controlling the three-point
hitch link arms 318 and 324 (see FIG. 3) and utilizes a fluid reservoir.
A guidance signal is received by the receiver 110 or 110e which is
connected to the driver controller 150. The antenna (not shown) is
optionally provided to enhance the reception of the guidance signal to
the GPS receiver 110e, but not requires for a laser receiver 110. The
driver controller 150 transmits a signal to the automatic double action
hydraulic valve 238 to control the driver 80. If the hydraulic valve
option switch 240 is in the automatic position, the automatic double
action hydraulic valve 238 controls the driver 80. If the hydraulic valve
option switch 240 is in the manual position, the automatic double action
hydraulic valve 238 does not receive hydraulic fluid and is not
operational, and thus the manual double action hydraulic valve 236
controls the driver at the tractor operator's initiation. Hydraulic power
receptacles 242 provide connect and disconnect locations for the
hydraulic lines leading from the hydraulic fluid valves to the driver 80
for connection and removal of the apparatus from the three point hitch of
the mobile machinery.
[0382] Electrical power from the mobile machinery battery is used for
powering the drive controller 150 and signal receiver 110 or 110e.
[0383] FIG. 4b is a flow chart depicting an electric driver and related
components of the present invention apparatuses. As in the hydraulic
version, a guidance signal is received by the receiver 110 or 110e which
then transmits the signal to the driver controller 150. The driver
controller 150 sends a signal to an automatic electric switch 248 to
control the driver 80. If an electric option switch 250 is in the
automatic position, the automatic electric switch 248 controls the driver
80. If the electric option switch 250 is in the manual position, the
automatic electric switch 248 does not receive electric current and is
not operational, therefore allowing the manual electric switch 246 to
control the driver at the tractor operator's initiation. Electric power
receptacles 244 provide connect and disconnect locations for the
electrical conductors leading from the electric switches to the driver 80
for the connection and removal of the present invention apparatuses from
the three point hitch of the tractor.
[0384] A typical method of using the invention for agricultural comprises:
[0385] 1. Choose a guidance system: [0386] a. Manual or automatic.
[0387] b. If manual, choose single tractor operator or double tractor
operator. (Double operator--first operator steering the tractor and the
second operator manually controlling the apparatus driver 80). [0388] c.
If automatic, choose GPS guided, laser guided, guidance wire guided or
other. [0389] d. If automatic is chosen, the guidance system must be set
up and installed.
[0390] 2. Row and raised bed crops utilizing the guided system with all
steps for any or all of the following: [0391] a. Precision tilling or
preparing the soil for planting. [0392] b. Precision position spraying of
herbicides and/or insecticides prior to planting if required. [0393] c.
Precision laying or dropping fertilizer if required. [0394] d. Precision
position installing drip tape if required. [0395] e. Precision position
installing of mulch or plastic culture if required. [0396] f. Precision
position planting of seeds or transplanting seedlings. [0397] g.
Precision position spraying of herbicides and/or insecticides after
planting if required. [0398] h. Precision position weeding with soil
cultivation or weed cutting when required. [0399] i. Precision position
harvesting.
[0400] The invention can also be used for earth excavating and grading.
[0401] Among the advantages of the invention with a guided system are:
[0402] a) The horizontal adjustments of the present invention provide an
accurate system of obtaining the desired path of excavation and soil
preparation as compared to utilizing an automated steering device of the
mobile machinery as the only form of implement path guidance. [0403] b)
Utilizing mobile machinery steering guidance combined with mobile
machinery implement guidance creates a more accurate system of obtaining
the desired path of excavation and soil preparation as compared to
utilizing an automated steering device of the mobile machinery as the
only form of implement path guidance.
