An agricultural implement includes a tow bar assembly for towing the implement with a towing vehicle. The tow bar assembly includes a tow bar mounted to a part of the implement by a first pivot bearing so as to be pivotable about a first vertical axis. The tow bar assembly includes an arm parallel with and spaced vertically below the tow bar. The arm is attached to the part of the implement by a second pivot bearing so as to be pivotable about a second vertical axis that is coaxially located with the first vertical axis.

A dual path agricultural machine including a control system having a number of input sensors, status sensors, and output sensors, and a controller configured to operate the dual path machine in a stability control mode and a selective rear-steer engagement and actuation mode. In the stability control mode, the controller adjusts an actual drive output of the dual path machine according to data received from the input sensors and feedback received from the output sensors so as to reduce a difference between the actual drive output and a desired drive output. In selective rear-steer engagement and actuation mode, the controller engages rear-steer mechanisms with caster wheels of the dual path machine and actuates the caster wheels via the rear-steer mechanisms if a criterion is satisfied. The controller disengages the rear-steer mechanisms from the caster wheels or does not actuate the caster wheels if the criterion is not satisfied.

A method for autonomously maneuvering a tractor in reverse for attachment to a trailer using a hitch assist system, the method including: entering a hitch assist mode, displaying a camera image on a user interface, and receiving an indication of a selected trailer. The method also includes determining a planned path with a computing device a tractor path from an initial position to a final position adjacent the trailer, the tractor path including maneuvers configured to move the tractor along the tractor path from the initial position to the final position. The method also includes autonomously following, at a drive system in communication with the computing device, the tractor path from the initial position to the final position.

An offset arm for a tractor is provided. The offset arm includes a front hitch, a rear hitch, and a rigid connecting structure coupling the front hitch to the rear hitch. The offset arm also includes a front pivot point pivotally connecting the connecting structure to the front hitch about a vertical pivot axis and a rear pivot point pivotally connecting the connecting structure to the rear hitch about a vertical pivot axis. The offset arm also includes a rear pivot lock that selectively locks the rear pivot point to lock the orientation of the rear hitch relative to the connecting structure. The rear pivot lock can selectively lock the rear hitch in any of multiple orientations.

An agricultural hitch with a system for management and guidance of maneuvers and a method employed by the hitch is provided. The hitch includes a tractor, an agricultural machine hitched by an articulated linkage, and a system for management and guidance of maneuvers, provided with a computing and control unit. The computing and control unit or of the hitched agricultural machine constitutes the master unit of the system for management and guidance of maneuvers, and is adapted to compute a set path for a maneuver to come, by employing an algorithm for prediction of paths and an algorithm for optimization of path settings, and to automatically execute the maneuver or of assisting in semiautomatic execution of the maneuver by steering the tractor and by recording, during maneuvering, the differences between the predefined set path and the real or currently estimated path.

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.

A grain cart is provide having a wheel assembly with four ground wheels that all pivot in unison. The wheel assembly can include a first side front wheel, a first side rear wheel, a second side front wheel and a second side rear wheel. A first side steering link assembly can be operatively coupled between the first side front wheel and the first side rear wheel to cause the first side front wheel and the second side rear wheel to pivot in opposite directions. A second side steering link can be operatively coupled between the second side front wheel and the second side rear wheel to cause the second side front wheel and the second side rear wheel to pivot in opposite directions. A unison linkage assembly operatively can couple the movement of the first side rear wheel and second side rear wheel.

A work machine, with a frame member, a ground engaging mechanism coupled to the frame member and configured to at least partially contact an underlying surface, a sensor coupled to the ground engaging mechanism, the sensor positioned to identify a displacement of the ground engaging mechanism relative to the frame, a controller in communication with the sensor, and a location system in communication with the controller. Wherein, the controller marks a location that corresponds with the position of the ground engaging mechanism, the location being identified by the location system when the sensor identifies the displacement of the ground engaging mechanism.

An articulated towing apparatus pulls a rotary driven implement in a forward working direction across a ground surface behind a towing vehicle. The apparatus includes a longitudinal frame pivotally connected at a leading end to the towing vehicle by a coupling frame and pivotally connected at a trailing end to a wheeled frame that supports the implement thereon. The coupling frame defines lateral and vertical pivot axes between the longitudinal frame and the towing vehicle. A drive line, connected between a power take-off of the towing vehicle and the implement, includes (i) a longitudinal drive shaft extending at a downward slope, and (ii) an output for connection to the implement that is rotatably supported on the wheeled frame.

An implement operating apparatus has a U-shaped drive frame supported on drive wheels, each pivotally mounted about a vertical wheel pivot axis. A steering control selectively pivots each drive wheel. A power source is connected through a drive control to rotate the drive wheels in either direction. First and second implements are configured to perform implement operations and to rest on the ground and when the drive frame is maneuvered to an implement loading position with respect to each implement, the implement is connectable to the drive frame and movable to an operating position supported by the drive frame. When the implement is in the operating position, the steering and drive controls are operative to move and steer the drive frame and implement along a first travel path or a second travel path oriented generally perpendicular to the first travel path.
