A method of measuring the quantity of wrap remaining on a round baler supply roll uses the existing wrap measuring apparatus of a round baler. An on-board microprocessor is programmed to calculate the minimum amount of wrap required for each bale, subtract the amount of wrap used to wrap a bale from the amount of wrap on the supply roll before wrapping the bale, and signal the operator if the amount on the roll is insufficient to wrap a bale. The microprocessor can also be programmed to signal the operator if the amount of wrap on the roll is insufficient to wrap a number of bales specified by the operator.

A drawbar assembly is used to connect a farm vehicle, such as a tractor, to a towed implement. A sleeve is supplied for secure attachment to the frame of the farm vehicle, and dimensioned interiorly thereof to embrace the drawbar and allow sliding, reciprocating, co-axial movement of the drawbar in the sleeve. At least one hydraulic cylinder comprising a casing housing, a hydraulically actuable piston, and rod assembly therein with the rod extensible beyond the casing, is provided. One of the rod and casing is configured for connection to the drawbar, and the other of the rod and casing for connection to the farm vehicle. A hydraulic system is connected to the hydraulic cylinder to effect adjustment of the rod relative to the casing and thereby (1) position the drawbar axially of the sleeve, and (2) to pressurize the cylinder in accordance with the damping qualities desired for the load carried by the towed implement. In this manner, both position and load changes affecting the drawbar may be accommodated in the hydraulic cylinder independent of each other.

A steering system for a towable implement includes a steering sensor, an implement steering controller, a steering control valve, a steering cylinder, and an implement steering mechanism that steers the implement. The steering sensor measures, directly or indirectly, the angular position of the steerable wheels of the implement. The implement steering controller processes feedback from the steering sensor and with a desired steering angle, outputs a steering control signal that is input to the steering control valve. The steering control valve controls the flow of hydraulic fluid to the steering cylinder, which, in turn, powers the implement steering mechanism to turn the wheels of the implement. The steering system may be operated in various control modes, such as, a transportation steering mode, a corner and 180 turn steering mode, a swath tracking steering mode, crab steering mode, and a manual steering mode, which allows manual control of the steering system.

An agricultural implement system is provided that includes a row unit configured to deposit agricultural material into soil along a direction of travel. The agricultural implement system also includes a sensor configured to output a signal indicative of soil displaced by the row unit, and an implement controller communicatively coupled to the sensor. The implement controller is configured to determine a smoothness of a soil finish behind the row unit along the direction of travel based on the signal. The controller is also configured to adjust a parameter affecting the soil finish while the smoothness is outside of a desired range.

A PTO transmission system in a vehicle for transmitting power to a PTO shaft driving an implement comprises a planetary drive unit (3) having first and second input means (2, 5) and output means (4) coupled to the PTO shaft (8). The first and second input means are coupled to an output shaft of the vehicle engine (1) and to an output shaft (5) of drive motor means (7), respectively. Control means (11) control the transfer of power from a power source (4) to said drive motor means (7). The power source is a variable power generating means (6) driven by said PTO shaft. The drive motor means are configured and adapted to decrease or increase the rotational speed of the output means of the planetary drive unit on an increase or decrease of the power transferred to it, respectively.

A control system controls a pair of vehicles in coordination to traverse a respective pair of trajectories. The control system is configured to specify a plurality of successive waypoints, a safe stopping interval and an intermediate interval greater than the safe stopping interval, and exchange waypoints between vehicles. The system controls each vehicle in coordination with the other, senses a rate of exchange of waypoint data between the vehicles, and determines the safe stopping interval. The control system updates positions with additional waypoints as the respective vehicles pass by waypoints of the forecasted trajectory, determines the length of the forecasted trajectory remaining and compares it with the intermediate interval and the safe stopping interval. The system generates a warning signal if distance is less than the intermediate interval, and if the distance is less than the safe stopping interval, stops within the safe stopping interval.

A draft load control system for an agricultural tractor towing a trailed, ground-engaging implement that monitors implement height using sensors located on the tractor or sensors coupled to an on-board control communications system and adjusts the implement position in relation to the ground based on draft load, implement height, and tractor wheel-slip to maintain a more accurate, consistent draft load on the tractor while maintaining the implement engaged with the ground and preventing the tractor-implement ground speed from being reduced to zero.
