A work machine includes: a work vehicle; a work device coupled to the work vehicle; a control device that executes at least one of: a first control to control the work device based on a first command from the work vehicle; and a second control to control the work vehicle based on a second command from the work device; and a switching device that switches the control device between the first control and the second control.

A hitch assembly system may comprise a pair of fixed actuator support brackets mounted to a vehicle frame and a pair of modular actuator connection brackets. Each modular actuator connection bracket of the pair of modular actuator connection brackets may be connected to a corresponding fixed actuator support bracket of the pair of fixed actuator support brackets. The system may further comprise a pair of lower links, in which each lower link of the pair of lower links is pivotally connected to the corresponding fixed actuator support bracket. A pair of electric linear actuators may be included in the system, in which each electric liner actuator of the pair of electric linear actuators is pivotally connected to a corresponding bracket end of a corresponding modular actuator connection bracket and a corresponding lower link. Each lower link may be moved by extension or retraction of a corresponding connected electric linear actuator.

A hitch mechanism for a work vehicle configured for operation on slopes. The hitch mechanism couplable to a tether fixed in position up the slope. An arm extends outwardly and upwardly from the work vehicle frame and supports a tether engaging structure couplable to the tether. The arm is mounted to the frame structure beneath the body portion of the work vehicle and extends rearwardly from the frame to support the tether engaging structure rearwardly of the body portion and rearwardly of the ground engaging drive mechanism. The hitch includes a pivot structure coupling the arm to the frame that allows the arm to pivot about a horizontal axis such that the arm is shiftable vertically. A controller receives inputs corresponding to at least one vehicle parameter and is operatively coupled to an actuator for causing the arm to shift in response to changes in the vehicle parameter.

A harvester may include a feeder house, a header mount interface proximate the feeder house; a header removably mounted to the feeder house by the header mount interface, the header having a mount interface for securing the header to a trailer; a sensor to output steering angle signals indicative of a steering angle of the harvester during an approach of the harvester carrying the header towards the trailer, and a controller to output control signals causing the display to overlay a representation of the mount interface on a real-time view of the approach.

A system includes a tractor comprising a lifting hitch, and an implement comprising an implement frame carried by the lifting hitch. The implement frame has an integrated elongate toolbar carrying at least one row unit. A sensor is configured to sense a position of the at least one row unit relative to the ground. A control system is configured to receive a signal related to the sensed position of the at least one row unit relative to the ground and cause the lifting hitch to raise or lower a portion of the implement frame connected to the lifting hitch relative to the tractor based at least in part on the signal. Control systems and related methods are also disclosed.

A working vehicle includes a traveling vehicle to autonomously travel on a target traveling route, a working device attached to the traveling vehicle, an offset acquirer to acquire an offset amount and offset direction in a vehicle width direction between a width directional center of the traveling vehicle and a predetermined point in the working device, and a traveling position corrector to correct, based on the offset amount and the offset direction acquired by the offset acquirer, a traveling position of the traveling vehicle so that the predetermined point is located on the target traveling route.

A power hoist equipment crane system to be used with a tractor roll bar, the system including a pivotable support bar configured to be substantially U-shaped having two side portions and a middle portion connecting the two side portions, a cable support member provided to the pivotable support bar and configured to support a cable from a hoist, and bracket assemblies provided respectively proximate each end of the pivotable support bar and configured to couple the pivotable support bar to the tractor roll bar in a pivoting arrangement, the bracket assemblies configured such that the pivotable support bar is pivotable between a substantially vertical stowed position when not in use, and a substantially horizontal use position in which the cable support member is positioned at a point spaced back from the tractor so as to be located over an implement that is attachable to the tractor.

A method for determining a physical parameter of an adjustable upper link of a three-point hitch during a working operation thereof includes providing a lower link of the three-point hitch and an implement attachable to the upper and lower links of the three-point hitch. The method includes generating calibration data prior to the working operation of the three-point hitch, where the calibration data defines a relationship of a length of the upper link to an upper link angle defined between the upper link and a reference line. Moreover, the calibration data is used to determine a physical parameter of the adjustable upper link during the working operation.

A work vehicle includes a first ground-engaging implement and a second ground-engaging implement connected to a chassis. The first ground-engaging implement moves within a first movement envelope with respect to the chassis, and the second ground-engaging implement moves within a second movement envelope with respect to the chassis. A lift arm is connected to the chassis and positioned between the first and second ground-engaging implements. The lift arm moves along a range of movement between a raised position and a lowered position. The lift arm is entirely positioned outside both of the first movement envelope and the second movement envelope within the entire range of movement between the raised position and the lowered position, such that the lift arm is permitted to move along the entire range of movement between the raised position and the lowered position without abutting the first movement envelope or the second movement envelope.

A working vehicle includes a steering device to steer a vehicle body, a working device connected to the vehicle body, an automatic steering controller to perform automatic steering of the steering device based on a difference between a scheduled traveling line and a position of the vehicle body, and a parameter changer to change a control parameter of the automatic steering depending on the working device connected to the vehicle body.
