Descriptive Report of the Invention Patent for APPLIANCE, SYSTEMS AND METHODS OF AGRICULTURAL TOOL BAR.
Background [001] Agricultural toolbars such as planters have become larger and heavier as agricultural operations have become larger. In this way, farmers have increasingly recognized the potential to improve yield and reduce damage caused by compaction by such toolbars. As a result, there is a need in the art for systems, devices and methods of changing the weight between the toolbar and the tractor and between sections of the toolbar in order to reduce the agronomic damage caused by compaction. In addition, the pressure of time in carrying out planting operations has created a need in the art for efficient systems, devices and methods of folding agricultural toolbars between the field position and a planting position, and especially for toolbars having a field position in which curves and changes in topography are effectively negotiated.

Description [0030] Referring now to the drawings, where similar numerical references designate identical or corresponding parts across all views, figures 1 to 10 illustrate an agricultural toolbar 10. With reference to figures 1 and 2, the toolbar 10 is attached to a tractor (not shown) by a hitch set 400 and thus pulled in the direction indicated by the arrow F. Hitch set 400 is attached to a weight transfer set 500. The weight transfer set 500 is preferably pivotally connected to draft tubes 120 by pins 128 for relative movement around substantially vertical geometric axes defined by pins 128. Draft tubes 120 are preferably pivotally coupled to doglegs 124 by pins 126 to perform relative movement in around the substantially vertical geometrical axes defined by pins 126. Doglegs 124 are preferably rigidly coupled sides to the inner wing sections 130. The inner wing sections 130 are preferably pivotally coupled to the outer wing sections 110 by pins 123 (see figure 7) to perform the relative movement around the substantially horizontal geometric axes defined by each pin 123. It should be appreciated that doglegs 124 allow draft tubes 120 to rotate with respect to wing sections 110 about a geometric axis of advance of outer wing sections 110 and outwardly of inner wing sections 130 without coupling draft tubes directly to the outer wing sections so that the outer wing sections are free to pivot around pins 123 without interference. The inner wing sections 130 are hingedly coupled to a central bar 330 by pins 334 (see figure 7) to perform the relative movement around
5/33 of substantially vertical geometric axes defined by pins 334. A central section 300 includes the central bar 330 and preferably additionally includes a fixing tube 310 rigidly coupled to the central bar 330.
[0031] Wing wheel assemblies 600 are preferably pivotally coupled to distal ends of outer wing sections 110. Center wheel assemblies 200 are preferably pivotally coupled to distal ends of central bar 330.
[0032] Comparing figures 1 and 2 with figures 9 and 10, the toolbar 10 is illustrated in its field and transport positions, respectively. In the field position of figures 1 and 2, the inner wing sections 130 and the outer wing sections 110 are in substantial alignment with the center bar 330 and the draft tubes 120 are in a generally transverse position. As the tool bar unfolds from the field position to the transport position, the inner and outer wing sections 130, 110 and doglegs 124 rotate forward and away from the center bar 330, while draft tubes 120 they move forward and rotate so that the inner ends of the draft tubes generally move forward while the distal ends of the draft tubes move both inward and outward. During the fold between field and transport positions, inner wing sections 130, doglegs 124 and draft tubes 120 form a diamond-shaped arrangement. Since the toolbar 10 is in the transport position of figures 9 and 10, the inner and outer wing sections 130, 110 are substantially perpendicular to the central bar 330 and the draft tubes 120 and doglegs 124 are substantially parallel to each other another in a generally longitudinal position. It should be appreciated that the term longitudinal as used here refers to the direction parallel to the direction
6/33 of travel while the transverse term refers to the normal direction with respect to the direction of travel and parallel to the ground surface. [0033] With reference to figure 7, where a part of the toolbar 10 is illustrated with a proximal part of the draft tubes 120 removed, each draft tube 120 includes upper and lower gears 129 hingedly connected to the transfer kit. weight 500 per pin 128. The left gears 129-1 are complementary to and operationally engaged with the right gears 129-2. As draft tubes 120 rotate between transport and field position, left and right gears 129-1 and 129-2 remain operationally engaged as pins 128 are kept at a fixed relative lateral distance by their connection to the weight transfer set 500. The operational engagement of gears 129-1 and 129-2 restricts gears 129-1 to rotate by an equal and opposite angle around pin 128-1 as an angle by which gears 129-2 revolve around pin 128-2 and vice versa. In this way, gears 129 restrict draft tubes 120 to articulate in a synchronized and symmetrical manner around a vertical longitudinal plane so that the angles between each of the draft tubes 120-1, 120-2 and the transfer frame weight 510 remain substantially equal and opposite through folding and unfolding operations, and so that the angles between each of the inner wing sections 130-1, 130-2 and center bar 330 remain substantially equal and opposite across all fold and unfold operations. It should be appreciated that the gears synchronization cooperation 129 causes the toolbar 10 to retain the substantially symmetrical configuration around a vertical longitudinal plane defined by the weight transfer frame 510. In other embodiments of the toolbar 10, inner wing sections 130 are provided with gears engaged
7/33 complementarily and operationally mounted on the inner ends of the inner wing sections so that the inner wing sections are restricted to rotate at equal and opposite angles to the center bar 330 as the toolbar folds . In other modalities of the toolbar 10, the gears are replaced by other synchronization mechanisms also configured to operationally engage the left and right elements of the toolbar in order to restrict the toolbar 10 to have a symmetrical configuration during the fold and unfold.
[0034] With reference to figures 2 and 3, the wing folding actuators 132 are mounted on the toolbar 10 and are preferably configured to fold the toolbar between the field and transport positions described here; specifically, the wing folding actuators 132 are preferably configured to rotate the inner wing sections 130 forward and away from the center bar 330 as the actuators 132 extend. Each actuator 132 is pivotally mounted at a first end to one of the inner wing sections 130 and pivotally mounted at a second end to one of the distal ends of the center bar 330. The wing flexors 122 are mounted to the bar of tools 10 for changing the weight between inner and outer wing sections 130, 110. Each actuator 122 is pivotally mounted at a first end to a distal end of inner wing section 130 and pivotally mounted at a second end to a proximal end of the outer wing section 110.
[0035] With reference to figures 4, 5 and 6, the coupling set
400 includes mounting points 440 configured to attach to draft connections on a tractor and a mounting point 450 configured to attach to the upper gain of a quick coupler (for example, described in US patent application No. 11 / 337,885 , the description of which is incorporated here by reference in its entirety) mounted on a three-point hitch on the tractor. Mounting points 440, 450 are fixed in a spaced relationship by a hitch tower 490 and a hitch panel 492. Mount points 440-1, 440-2 are preferably configured for attachment to the lower left and right hooks, respectively , of a quick coupler mounted on a tractor's three-point coupling. Each mounting point described here preferably comprises a pin configured to be engaged by a corresponding structure on a three point quick coupler. In other modalities, the mounting points are configured to be engaged by the corresponding structure in a three-point coupling (for example, in such modalities the upper mounting point 450 is configured to be coupled to the upper connection of the three-point coupling and the mounting points 440 are configured to be coupled to the lower connections of the three point hitch).
[0036] A connection plate 480 is pivotally mounted on the coupling tower 490 by two pins 410a, 410b. The connecting part 480 articulates with respect to the coupling tower 490 around a generally vertical geometric axis extending through the pins 410a, 410b. The joint plate 480 is pivotally mounted on a lower joint plate 425 by a pin 420. The joint plate 480 articulates with respect to the lower joint plate 425 around a generally longitudinal axis extending through pin 420. A lower link plate 425 is pivotally mounted to the weight transfer set 500 by a pin 430. The lower link plate 426 rotates with respect to the weight transfer set 500 about a generally horizontal transverse axis extending9 / 33 through pin 430.
[0037] With reference to figures 4 and 5, the weight transfer set 500 includes a weight transfer frame 510. A weight transfer actuator 520 is pivotally mounted at a first end to the weight transfer frame 510 and at a second end to the connecting plate 480. As illustrated, the weight transfer assembly 500 is preferably configured so that the pressure increase at the front end (i.e., the lifting pressure) of the weight transfer actuator 520 transfer part of the weight from the toolbar 10 to the tractor, while increasing the rod end pressure (i.e. downward pressure) from the weight transfer actuator 520 transfer a part of the tractor weight to the toolbar . Specifically, it should be appreciated that the relative locations of the weight transfer actuator assembly joints 520 allow the weight transfer actuator to create an impulse around pin 430 acting on the weight transfer frame 510. A jack-type support 530 extends through the weight transfer frame 510 and is preferably configured to selectively lower to reach ground contact and the vertical support of the toolbar 10.
[0038] Again with reference to figures 4 and 5, the toolbar 10 includes a lock assembly 350 including a lock plate 358 slidably mounted to the central section 300 for vertical translation with respect to the central section. Lock plate 358 includes upper left and right hooks 354a-1.354a-2 that engage upper left and right bars 356a-1, 356a-2, respectively, when the lock plate is in its lowered position. Locking plate 358 includes lower left and right hooks 354b-1, 354b-2 that engage the lower left and right bars 356a-1,
10/33
356a-2 when the lock plate is in its lowered position. The upper bars 356a and the lower bars 356b are mounted on the weight transfer frame 510 so that when the lock assembly is engaged, the weight transfer assembly 500 is rigidly mounted to the center section 300 and the tool bar 10 is thus prevented from unfolding to the transport position. Turning to figure 10, a locking actuator 370 is mounted on a first end to the central section 300 and on a second end to the locking plate 358 for selective lifting and lowering of the locking plate and, thus, for the engagement and selective disengagement of lock set 350 when tool bar 10 is in the field position.
[0039] With reference to figures 1 and 10, the latches 102 are mounted at distal ends of the outer wing sections 110. In the transport position (figure 10), the latches 102 engage the draft tubes 120 to prevent the draft sections external wing 110 rotate away from the draft tubes and articulate vertically with respect to the draft tubes. The latches 102 thus retain the tool bar 10 in the transport position.
[0040] With reference to figure 8A, the right central wheel assembly 200-2 is mounted on a right distal end of the central bar 330. A mounting bar 210 is mounted on the central bar 330 and positioned above the central bar. A central wheel frame 230 is pivotally mounted to the central bar 330 by a cross extension pin 225. A central wheel driver 220 is pivotally mounted at a first end to the mounting bar 210 and pivotally mounted at a second end to the central wheel frame 230 for selective lifting and lowering of the toolbar 10. A wheel frame 240 is pivotally mounted to the central wheel frame 230 around a pin
11/33 transverse 235. A lead wheel 250 is rolled to a leading end of the wheel frame 240. A rear wheel 260 is rolled to a rear end of the wheel frame 240. In operation, the the center wheel assembly rolls the weight of the tool bar 10 in a rolling fashion and the wheel frame 240 pivots to allow the front and rear wheels 250, 260 to move up and down relative to each other as the set of wheels central wheel encounters obstructions or uneven ground.
[0041] With reference to figure 8B, the right wing wheel assembly 600-3 is mounted on the right distal end of the external wing section 110-2. A mounting bar 610 is mounted on the outer wing section 110 and above and behind the outer wing section. A wing wheel frame 640 is pivotally mounted to the outer wing section 110 by one or more pins of transverse extension 635. A wing wheel 650 is rolled to a rear end of the wing wheel frame 640. A driver 620 is pivotally mounted at a first end to the mounting bar 610 and pivotally mounted at a second end to the wing wheel frame 640 to raise and lower the wing section 110. The actuators 220, 620 are preferably hydraulic cylinders double drive.
[0042] With reference to figure 2, the tool bar 10 includes vacuum ports 115 formed in the outer wing sections 110 at intervals spaced transversely, the vacuum doors 335 formed at central bar 330 at spaced intervals transversely, and a vacuum exhaust port 315 formed in the fixation tube 310. A vacuum propellant (not shown) is preferably mounted on the fixation tube 310 and in fluid communication with the vacuum exhaust port 315. Referring to figure 11 Β, the fixing tube 310, the central bar 330, the inner wing sections 130 and the
12/33 outer wing sections 110 have internal volumes 940, 930, 920, 910, respectively. Internal volumes 910 and 920 are in fluid communication through flexible tubes 915. In the field position illustrated in figure 11B, internal volumes 930, 920 are in fluid communication through the combination of holes 924, 926 (figure 11 A) formed in the internal wing sections 120 and central bar 330, respectively. The holes 924 are each preferably fitted with a resilient seal (not shown) so that the holes 924 are in connection with resilient fluid with the holes 926. The internal volumes 930, 940 are in fluid communication through a hole 935 (figure 7) formed on the central bar 330 and an open feed end of the fixing tube 310.
[0043] Thus, in the field position, the internal volumes 940, 930, 920, 910 form a single internal volume 900 (figure 11B). Internal volume 900 comprises a substantially closed volume except for ports 315, 335, 115. In this way, the vacuum propellant pushes a subatmospheric pressure in the internal volume so that air flows into ports 335, 115 and out of the door. vacuum exhaust 315.
[0044] Soil attachment tools such as row planting units, as illustrated in US Patent No. 6,932,236, incorporated herein in their entirety by reference, can be mounted on center bar 330 and wing sections external 110. The vacuum gauges associated with said row units are preferably in fluid communication with vacuum ports 115, 335. In other embodiments, other tools for engaging with the ground such as groove-forming can be mounted on the bar center 330 and external wing sections 110.
Control Systems [0045] With reference to figure 12, an 800 control system is
13/33 illustrated including a fluid control system 810 in fluid communication with lock actuator 370, weight transfer actuator 520, wing flex actuators 122, wing fold actuators 132, wing actuators wing wheel 620, and center wheel drives 220. Fluid control system 810 is also in fluid communication with a fluid pump 820 through both an overpower port 816 and a selective control valve 814. A fluid pump 820 is also in fluid communication with the tractor's 880 draft connection cylinders. The fluid pump 820 may comprise a tractor-based hydraulic pump.
[0046] The fluid control system 810 preferably comprises a set of electro-hydraulic control valves, each in fluid communication with one or more chambers of the associated actuator. Each control valve includes a solenoid or other electronic control that is in electronic communication with an 830 monitor. The 830 monitor includes a central processing unit (CPU), a memory, and a user interface such as a graphical user interface. touch screen.The monitor 830 is also preferably in electrical communication with the center wheel position sensors 860, wing wheel position sensors 864, center wheel load sensors 822, and wing wheel load sensors 862.
[0047] Central wheel position sensors 860 and wing wheel position sensors 864 preferably comprise Hall Effect sensors configured to detect the stem extension of central wheel drives 220 and wing wheel drives 620, respectively . The central wheel load sensors 822-1, 822-2 comprise sensors configured to detect the load carried by the central wheel drivers 220-1 and 220-2. Specifically,
14/33 center wheel load sensors 822-1, 822-2 can comprise instrumented pins by which the front ends of the center wheel drivers 220-1, 220-2 are mounted on the mounting bars 210-1, 210-2 (see figure 8A), such as the model number CLP-18k available from Transducer Techniques, Inc., of Temecula, California. Wing wheel load sensors 862-1, 862-2 comprise sensors configured to detect the load carried by the wing wheel drivers 620-1, 620-2. Specifically, the wing wheel load sensors 862-2, 862-2 can comprise instrumented pins by which the front ends of the wing wheel drivers 862-1, 862-2 are mounted on the mounting bars 210-1, 210 -2 (see figure 8B), such as the CLP-12-5k model number available from Transducer Techniques, Inc., of Temecula, California. In other embodiments, the load sensors 862, 822, can comprise any type of load cell or strain gauge configured to measure the force applied between the ground and the wheel assemblies.
Control Systems - Foldable Hydraulic Part [0048] Figure 16 illustrates a modality of the 810 fluid control system including a 1600 bend control system. The bend control system includes a pressurized oil port 1602 and a tank port 1604 in fluid communication with the selective control valve 814. The selective control valve 814 is in fluid communication with a wrap drain 1608 through a small orifice 1607. The selective control valve 814 can comprise a selective control valve such as those included in the most commercially available tractors and located in the tractor cab for manual operation by the operator. The selective control valve 814 is in fluid communication with the left and right wing folding actuators 132-1, 132-2 via a di
15/33 valve operated by solenoid 1620 and a flow divider valve 1630. Monitor 830 is in electrical communication with directional valve 1620. During operation, monitor 830 allows folding of the wing by opening the directional valve 1620. The operator selects the direction of the wing fold (i.e., retraction or extension of the wing fold triggers 132) by selecting the position of the selective control valve 814. The flow divider 1630 maintains equal flow between the left wing fold triggers and right 132-1, 132-2, thus synchronizing the folding of the left and right components of the toolbar 10.
[0049] Selective control valve 814 is in fluid communication with lock actuator 370 through a directional valve operated by solenoid 1640. Directional valve 1640 is in electrical communication with monitor 830. During operation, monitor 830 allows operation of the lock by opening the 1640 directional valve. The operator selects the direction of movement of the lock (that is, extension or retraction of the lock cylinder 370) by selecting the position of the selective control valve 814.
Control Systems - Hydraulic Lift Part [0050] Figure 17 illustrates a modality of the 810 fluid control system including a 1700 lift control system. In the 1700 lift control system, fluid communication between the 620 drives, 220 and pressurized oil and tank ports 1602, 1604 are controlled by a 1753 pilot operated check valve, a 1734 solenoid operated directional valve, a 1744 solenoid operated one way stop valve, a 1724 flow divider valve , 1754-1, 1754-2 balance valves, a 1755 solenoid operated directional valve, a 1723 flow divider valve, and a 1733 solenoid operated directional valve.
[0051] The 1734 solenoid operated directional valve, the valve
16/33 single-way blockage operated by solenoid 1744, the directional valve operated by solenoid 1755, and the directional valve operated by solenoid 1733 are preferably in electrical communication with the monitor 830.
[0052] In operation of the control system 1700 in the configuration illustrated in figure 17, the pressurized oil from the pressurized oil port 1602 flows respectively through the selective control valve 814, the directional valve 1734, the one-way stop valve 1744, and the flow divider 1724, which separates the oil into two flow paths having a substantially equal flow rate. The oil following both flow paths then travels through the 1754 balance valves and to the front ends of the center wheel drives 220. As the oil enters the front ends of the center wheel drives 220, the center wheel drives become extend so that oil flows from the stem ends of the center wheel drives. The oil then flows into the front ends of the wing wheel drivers 620, extending the wing wheel drivers so that oil flows from the rod ends of the wing wheel drivers. The oil then flows through the pilot operated check valve 1753, which is opened by the pressurized oil in its pilot line, and through the selective control valve 814 to the tank port 1604. The oil is also consistently allowed to bleed in. of the drain drain 1608 through the small hole 1607. It should be noted that in this configuration, the tool bar 10 is raised upwards.
[0053] During the operation of the 1700 control system in the configuration illustrated in figure 7 modified where the selective control valve 814 is in its lowest (crossed) position, the oil flows through the components mentioned above in reverse order,
17/33 so that the central wheel actuators 220 and the wing wheel actuators 620 retract, lowering the toolbar 10 towards the ground.
[0054] In other configurations selected by the 1700 control system operator, the wing wheel actuators 620 can be extended and retracted while blocking the flow of oil to the center wheel actuators 220 by changing valve positions 1733, 1755, 1744, 1734.
[0055] A new phase 1715 valve is preferably in fluid communication with each of the actuators 620, 220, allowing the actuators to continue to extend or retract if the equivalent actuator on the other side of the toolbar 10 reaches the fully extended position or retracted first.
Control Systems - Hydraulic Weight Management Part [0056] Figure 18 illustrates a modality of the fluid control system 810 including a 1800 weight management control system. In the 1800 weight management control system, the excessive power 816 and tank port 1604 are in fluid communication with the stem ends of the right and left wing flexure actuators 122-1, 122-2 through the 1820-1 solenoid operated pressure relief valves , 1820-2. Excessive power port 816 and tank port 1604 are in fluid communication with the front ends of the right and left wing flexure actuators 122-1, 122-2 through the relief and pressure reduction valves operated by solenoid 1825 -1, 1825-2. The 1820-1, 1820-2, 1825-1, 1825-2 valves are in electrical communication with the 830 monitor. During operation, the monitor sends a command current to the 1820-1, 1820-2, 1825- 1, 1825-2 in order to create a desired net pressure (the sum of the head and rod end pressures) in the wing flexion actuators18 / 33 122-1, 122-2.
[0057] The over-power port 816 and the tank port 1604 are in fluid communication with the stem end of the weight transfer actuator 520 via a 181- solenoid operated pressure relief valve and a valve pilot operated directional switch 1815. The front end of the weight transfer actuator is in fluid communication with tank port 1604. Valve 1810 is in electrical communication with monitor 830. In operation, monitor 830 sends a command current for valve 1810 to create a desired lift pressure on the weight transfer driver 520. When monitor 830 sets the lift pressure to tank pressure (for example, 0 psi), valve 1815 places the actuator stem 520 in fluid communication with tank port 1604, allowing the actuator stem 520 to float.
[0058] The monitor 830 is preferably configured to allow the operator to select the desired weight transfer parameters. A 1900 screen for recording the desired weight transfer parameters and displaying the actual weight transfer parameters is illustrated in figure 19. The 1900 screen includes a 1902 graphic weight management window. The 1902 window preferably includes wing load monitors. 1915-1, 1915-2, which display the loads measured by the wing wheel load sensors 862-1, 862-2, respectively.

Control Methods
Control Methods - Toolbar Settings [0066] The 810 fluid control system controls wing folding triggers 132 in a flow control mode. In response to a command recorded on the 830 monitor or manipulation of the
22/33 selective control 814, the fluid control system 810 extends and retracts the wing folding triggers 132 in order to reconfigure the toolbar 10 in its transport position and field position, respectively.
[0067] Fluid control system 810 controls wing wheel drivers 620 and center wheel drivers 220 in a flow control mode. In response to a command recorded on the monitor 830 or manipulation of the selective control valve 814, the fluid control system 810 extends or retracts the wing wheel actuators 620 and the central wheel actuators 220 between various operating positions. The operating positions of the wheel actuators 620 and center wheel actuators 220 include a field position, a more retracted transport position and a curve position at the end of the row between the field position and the transport position.
[0068] A 2300 process for folding the toolbar from the transport position to the field position is illustrated in figure 23A. In step 2305, monitor 830 preferably commands the fluid control system 810 to lower the wing wheels 600 by the extension of the wing wheel drivers 620. In step 2310, the latches 102 are disengaged as the wing wheels 600 they raise the wing sections 110 with respect to draft tubes 120. In step 2315, the operator preferably drives the tractor backwards or allows the tractor to roll backwards. In step 2320, monitor 830 preferably commands fluid control system 810 to retract wing folding triggers 132. In step 2325, monitor 830 preferably commands fluid control system 810 to engage lock set 350 through lock actuator retraction 370. In step 2330, the operator preferably lowers the tractor's three-point hitch to a lowered field position. In step 2335, monitor 830 preferably controls the fluid control system for
23/33 lower the toolbar 10 to a lower field height by the total retraction of the central wheel drives 220 and wing wheel drives 620.
[0069] A 2350 process for folding the toolbar from the transport position to the field position is illustrated in figure 23B. In step 2355, the monitor preferably controls the fluid control system to raise the toolbar 10 to a high transport height over the full length of the central wheel drives 220 and wing wheel drives 620. In step 2360, the operator preferably raises the tractor's three-point hitch to a high transport height. In step 2365, monitor 830 preferably commands the fluid control system 810 to disengage the lock assembly 350 by the extension of the lock actuator 370. In step 2370, the monitor 830 preferably commands the fluid control system 810 to extend the actuators wing folding 132. In step 2375, the operator preferably drives the tractor forward or allows the tractor to roll forward. In step 2380, monitor 830 preferably commands the fluid control system to raise wing wheels 600 by retracting wing wheel drivers 620. In step 2385, latches 102 are engaged as wing wheels 600 lower the wing sections 110 with respect to draft tubes 120.
[0070] Monitor 830 is preferably configured to raise the toolbar from the field position to an end-of-row curve configuration by simultaneously extending the center wheel drivers 220 and the wing wheel drivers 620 until a predetermined signal be received from one or both of the wing wheel position sensors 864 or from the center wheel position sensors 860. The monitor 830 is also preferably configured to return the toolbar from the end of curve setting
24/33 row to field position by complete retraction of the 620 wing wheel actuators.
Control Methods - Weight Management [0071] The fluid control system 810 preferably controls the weight transfer actuator 520 and the wing flexion actuators 122 in a pressure control mode. Various methods of weight management (i.e., changing vertical loads between the tractor, the center section 300, and the wing sections 110) using the weight transfer actuator 520 and the wing flexion actuators 122 are described here. It should be noted that in each mode, the monitor 830 controls the desired pressures by sending command signals to the relief and pressure reduction valves associated with the actuators 122, 520.
Control Methods - Weight Management - Command-Based Mode [0072] In a command-based weight management mode, the 830 monitor commands the constant pressures recorded in fields 2112, 2114, 2116 of the manual configuration screen 2100 (figure 21) for actuators 122-1, 122-2, 520, respectively. When a positive value is recorded in any of the fields 2112, 2114, the monitor 830 preferably controls the pressures of corresponding magnitude for the wing flexion chambers tending to extend the corresponding wing flexion driver 122 (in this way, the weight change from central section 300 to wing sections 110-1, 110-2). When a negative value is registered in any of the fields 2112, 2114, the monitor 830 preferably commands the pressures of corresponding magnitude for the wing flexion chambers tending to retract the corresponding wing flexion driver 122 (thus changing the weight of the wing sections 110-1, 110-2 for section 300).
25/33
Control Methods - Weight Management - Return Based Mode [0073] In a return based weight management mode, the 830 monitor controls the pressures for the 520, 122-1, 122-2 triggers based on the ranges of measured loads on the central wheel 200, wing wheel 600-1, and wing wheel 600-
2. The desired ranges of measured loads are preferably based on targets registered by the operator in fields 2126, 2122, 2124 of the 2100 manual configuration screen (figure 21). For example, each desired range can comprise a range between 95% and 105% of each target value. In other embodiments, one or more desired ranges are predetermined and saved in the 830 monitor's memory. In some embodiments, the monitor selects from multiple predetermined desired ranges depending on one or more variable operating parameters (for example, tractor speed).
[0074] A wing flex actuator control process 1300 for controlling each wing flex actuator 122 in a return-based mode is illustrated in figure 13A. In step 1310, monitor 830 preferably commands an initial pressure for wing flexion actuator 122. In step 1320, monitor 830 preferably receives a wing wheel load signal from the associated wing wheel load sensor 862 with the same wing section 110 as the wing flex actuator 122. In step 1330, monitor 830 preferably compares the wing wheel load signal with a desired range determined as discussed above. If the wing wheel load signal is above the desired range, then the monitor reduces the wing flexion trigger pressure commanded in step 1340. If the wing wheel load signal is below the desired range, then the monitor increases the pressure of the wing flexed actuator in step 1360. If the wing wheel load signal is within
26/33 of the desired range, then the monitor maintains the wing flexion trigger pressure previously commanded in step 1350.
[0075] A weight transfer actuator control process 1302 for controlling the weight transfer actuator 520 in a return-based mode is illustrated in figure 13B. In step 1365, monitor 830 preferably commands an initial lift pressure for the weight transfer actuator 520. In step 1370, monitor 830 preferably receives signals from both center wheel load sensors 822. In step 1375, the monitor 830 preferably compares the sum of the center wheel load signals with a desired range determined as discussed above. IF the sum of the load signal is below the desired range, then the monitor reduces the pressure transfer switch pressure commanded in step 1385. If the sum of the load signal is within the desired range, then the monitor maintains the pressure of weight transfer actuator previously controlled in step 1390. If the sum of the load signal is above the desired range, then in step 1378 the monitor 830 preferably compares the pressure of the current weight transfer actuator to the limit determined by the operator using of the force limit modification window 1950 as discussed here with respect to figure 19. If the pressure of the weight transfer actuator is below the limit, then the monitor 830 preferably increases the pressure of the wing flex actuator commanded in step 1380 If the pressure of the weight transfer actuator is not below the limit, then the monitor 830 preferably maintains the pressure of ac weight transfer ionator previously controlled in step 1390.
Control Methods - Weight Management - Weight Balance Mode [0076] In a weight balance mode of weight management
27/33 weight, monitor 830 controls pressures for actuators 520, 122-1, 122-2 based on a desired weight division between the tractor, central wheel assemblies 200, and wing wheels 600. The The desired balance of the measured loads is preferably based on the values recorded in fields 2025-1, 2025-2, 2030 using screen 2000.
[0077] A control circuit 1410 for controlling each wing flexion actuator 122 in a weight balance mode is illustrated in figure 14. In the control circuit, monitor 830 compares the measured output of the wing wheel load sensor 862 with a reference record 1412 preferably calculated according to the following relationship:
[0078] Reference Record = W _f (F _C i + F _C 2-F _H -T) [0079] Where:
[0080] W _f is the percentage of wing weight transfer, preferably recorded in one of the 2025 fields of the automatic configuration screen 2000, expressed as a fraction;
[0081] F _C ie F _C 2 are the signals from the central wheel load sensors 822-1,822-2, respectively;
[0082] F _h is an estimate of the amount of weight transferred from the toolbar 10 to the tractor, for example, using a multiplier (related to the effective area through which the cylinder pressure is imposed and the mechanical advantage of the set of weight transfer 500) of the pressure commanded on the weight transfer actuator 520; and [0083] T is the estimated weight on the rear wheels of the tractor or rail parts, registered by the operator in field 2020 of the automatic configuration screen 2000 or determined as described here in relation to figure 22.
[0084] The 830 monitor adjusts the pressure in the control valves
28/33
1825, 1820 associated with the wing flexion actuator 122 in order to reduce the error measured between the reference register 1412 and the measured output of the wing wheel load sensor 862. The monitor also preferably compares the pressure of the flexion actuator controlled wing or wing wheel load sensor signal with a lower limit so that the control circuit 1400 does not reduce the wing flexure pressure below the lower limit pressure or the pressure corresponding to the lower limit of the signal wing wheel load sensor.
[0085] In other modalities, the reference record 1412 is calculated according to the relation:
[0086] Reference Record = W _f (F _c -F _H -T / 2) [0087] Where:
[0088] F _c is the signal from the central wheel load sensor 822 associated with the central wheel on the same side of the toolbar as the wing wheel.
[0089] In other modalities, the reference record 1412 is calculated according to the relation:
[0090] Reference register = W _f (F _c ).
[0091] The wing weight transfer percentage W _f is preferably a predetermined value or can be based on user records as described here. The percentage of wing weight transfer is preferably based on a ratio between agronomic damage caused by weight on the center wheels and agronomic damage caused by weight on the wing wheels. The percentage of wing weight transfer W _f is preferably between 5% and 20%.
[0092] A method 2400 for controlling the pressure in the weight transfer actuator 520 is illustrated in figure 24. In step 2405, monitor 830 determines whether the current commanded engagement pressure is within a predetermined range. For the purposes of this description, the
Downward pressure is considered positive and the elevation pressure is considered negative. In embodiments in which the weight transfer set 500 is mounted on a quick coupler, the upper limit of the predetermined range applied in step 2405 is preferably approximated to the weight of the weight transfer set 500 so that the weight transfer actuator 520 can change the weight of the weight transfer set for the planter, but is prevented from raising the three-point hitch or lifting the weight transfer set from the three-point hitch. In the modalities in which the weight transfer set 500 is mounted on the quick coupler, the lower limit of the predetermined beech applied in step 2405 is preferably determined in order to avoid tilting the tractor or losing traction on the tractor's front wheels. For example, the lower limit can be based on the weight of the tractor, the distance between the center of gravity of the tractor and the rear axle of the tractor, the weight of the toolbar (preferably estimated at the total weight with all harvest input tanks loaded), and the distance between the center of gravity of the toolbar in the field position and the rear axle of the tractor so that a sufficient amount of weight is applied between the front wheels of the tractor and the ground.
[0093] If the pressure of the weight transfer trigger is outside the predetermined range of step 2405, in step 2410 the monitor 830 adjusts the pressure of the weight transfer trigger to the end closest to the predetermined range. For example, if the pressure of the commanded weight transfer actuator is lower (more negative) than the predetermined minimum, monitor 830 adjusts the pressure of the weight transfer actuator to the predetermined minimum.
[0094] If the pressure of the weight transfer driver is within the predetermined range of step 2405, in step 2415 the moni30 / 33 tor 830 preferably determines whether the sum of the toolbar wheel weights (that is, the sum of the signals from the center wheel load sensors 822 and the wing wheel load sensors 862) is at least a predetermined minimum, for example, 181 kg. In other embodiments, monitor 830 determines, instead, whether the sum of the center wheel load sensor signals is at least another predetermined minimum. It should be appreciated that a minimum weight on the toolbar weight is necessary in order for the tools to engage with the soil to function properly, for example, for row planting units to reach full trench depth; thus, the predetermined minimum is preferably determined empirically in order to ensure that the soil coupling tools can properly engage the soil. If the sum of the toolbar wheel weights is less than the predetermined minimum of step 2415, then in step 2420 the monitor 830 preferably reduces the pressure of the weight transfer driver by one step (for example, for a predetermined interval, for example a predetermined percentage of the current driver pressure, or using a PID algorithm).
[0095] If the sum of the toolbar wheel weights is less than the predetermined minimum of step 2415, then in step 2425 the monitor 830 preferably adjusts the pressure of the weight transfer driver using a control circuit based on the downward force of the wheel (for example, the sum of the signals from the central wheel load sensors 822) in order to minimize agronomic damage to the soil by the tractor wheels and the central wheels of the toolbar.
[0096] It has been empirically determined that approximately 80% of soil compaction (and related agronomic damage) occurs during the first compaction event. In this way, where the central wheel con31 / 33 together follow the path of the tractor wheels or rails, the agronomic benefits result from equalized loads between the tractor's rear wheels and the central wheel assemblies. In this way, a control circuit 1420 to be used in step 2425 of process 2400 for adjusting the pressure in the weight transfer actuator 520 in a weight balance mode is illustrated in figure 15. In control circuit 1420, the monitor 830 compares the sum of the measured outputs of the central wheel load sensor 822-1, 822-2 with a reference register 1422 preferably calculated according to the following relationship.
[0097] Reference Record = H _f (F _H + T) [0098] Where:
[0099] H _f is the percentage of coupling weight transfer expressed as a fraction; and [00100] F _H and T are the values described above with respect to figure 14A.
[00101] Monitor 830 adjusts the pressure at the control valve 1810 associated with the weight transfer actuator 520 in order to reduce the error measured between the reference register 1422 and the sum of the measured output of the central wheel load sensors 822 .
[00102] In some embodiments, the coupling weight transfer fraction H _f recorded in fields 2030 of the automatic mode configuration screen 2000 for storage in the 830 monitor memory as described above. In other embodiments, the H _f coupling weight transfer fraction is determined in order to equalize the agronomic damage caused by the rear wheels of the tractor or rails and the central wheels of the toolbar. Depending on the variables including the tractor model, the types of wheel or tractor tracks, and toolbar wheel configuration, and the type of toolbar wheels (all of which may be preferable32 / 33 selected using a screen similar to screen 2200 described here with reference to figure 22), an individual agronomic damage multiplier can be applied to each tractor tire (or rail) and each toolbar center wheel tire. The 830 monitor is preferably configured to select agronomic damage multipliers from an empirical lookup table stored in memory and calculate a fraction of coupling weight transfer H _f based on such variables selected or recorded on the monitor by the operator. For purposes of illustration, the agronomic damage multiplier can be related to the contact area between each tire (or rail) and the ground; it must be appreciated that the multiplier associated with each wheel is related to the amount of agronomic damage caused by the wheel per kg of soil force applied by the wheel. In modalities such as the toolbar modalities described here in which each central wheel set has multiple wheels following the same track, the economic damage multiplier associated with the entire central wheel set is preferably inversely related to the number of wheels in the central wheel assembly. The coupling weight transfer fraction H _f is preferably related to the ratio between the toolbar center wheel agronomic damage multiplier and the tractor wheel (or rail) tire agronomic damage multiplier.
Alternative Modes [00103] In other modalities of the 800 control system, the solenoid operated valves are in electrical communication with an electronic control box in the tractor cabin so that the operator can change the operational states of the valves without using the 830 monitor Thus, in the methods described here in which the 830 monitor commands a change in the operational state of a
33/33 valve operated by solenoid, it must be appreciated that the operator can perform such steps using such electronic control box.
