The disclosure relates to a towing hitch for a work vehicle. The towing hitch includes a retaining element. A coupling member coupled to the retaining element. A guide element having at least one guide channel formed therein; wherein the guide channel is sized to receive a portion of the retaining element. An actuator coupled to at least one surface of the retaining element, wherein the actuator is arranged such that lateral displacement of the actuator moves the retaining element between a first position and a second position within the guide channel of the guide element.

A steering system for controlling an agricultural machine having a pair of front and rear wheels includes a controller and a steer input sensor for detecting a change in an operator steer input corresponding to a steer command. The system includes a displacement input for communicating a motor displacement associated with an operating mode. A primary differential steering system includes a drive motor for operably controlling the pair of front wheels and a secondary steering system controls the pair of rear wheels. The controller determines if the motor displacement is being controlled according to a first motor displacement or a second motor displacement, and outputs a control signal to actuate first and second actuators as a function of the steer command. The control signal includes a rear steering gain that is a function of machine speed and either the first motor displacement or the second motor displacement.

A steering assistance system includes a combination of an agricultural tractor and an attached implement. A laser is mounted to the combination and is configured to beam a visual representation of an extrapolated path of a working edge forward of the implement.

An agricultural mower system includes: a towing vehicle including an engine and a tongue coupler and defining a towing centerline; a mower including a frame carrying cutters and pivotably coupled to a tongue that is pivotably coupled to the tongue coupler, the frame defining a mower centerline that is offset from the towing centerline, the tongue defining a towing angle with respect to the towing centerline and a mower angle with respect to the mower centerline; a mower angle actuator coupled to the tongue and the frame; and a controller configured to: determine the towing angle has changed by a change amount relative to a defined towing angle; determine a turn compensation amount for the mower angle as a function of the change amount and a constant; and output a compensation signal to cause the mower angle actuator to adjust the mower angle by the determined turn compensation amount.

A method for operating an agricultural vehicle. The method including capturing, by the at least one image capturing device, image data of the implement and receive, by the controller, the image data of the implement. The method further includes identifying the implement, by the controller, depending at least in part upon the image data of the implement. The method further includes setting, by the controller, at least one operational parameter of the implement, and managing, by the controller, a turning maneuver of the agricultural vehicle depending at least in part upon the image data of the implement.

A steerable towed implement towed by a tractor receives manual operator inputs to steer between right and left stop limits and a neutral position. The implement is steered by an actuator controlled by an actuator control system that causes the actuator to bring the implement to a neutral position in the absence of operator control inputs after a given period of time.

A conventional three point hitch of an agricultural tractor for the connection and use of working implements cultivating or excavating the earth and other duties involved in the industry of farming or grading excavation is modified by adding extending and retracting implement-actuators attachable to the existing bottom-lift-arms, therefore supplanting, but still using the existing bottom-lift-arms on the three-point hitch. The implement-actuators assist the implement in correcting the implements centerline when the tractor centerline is off a predetermined centerline path. In addition, the extending of the implement-actuators proportionally, inversely and simultaneously can correct the pivot point of the implement to match the pivot point of the tractor while the tractor performs turns during the working use of the implement.

In one embodiment, a windrower that comprises: a dual-path steering system configured to drive a pair of drive wheels in an opposite direction of rotation and in a same direction of rotation during non-overlapping time periods; and a steering axle system configured to actively steer a pair of caster wheels while the dual path steering system drives the pair of drive wheels during each of the non-overlapping time periods.

A line acquisition system predicts and displays an acquisition path to reduce the uncertainty surrounding the path taken by a vehicle when acquiring a destination path. The line acquisition system calculates the drivable acquisition path based on the current states of the vehicle, such as position, speed, heading, and curvature. The line acquisition system continually updates and displays the acquisition path as the vehicle is manually steered by the user. When the user engages a steering controller, the last calculated acquisition path is used to automatically steer the vehicle onto the destination path. Displaying the acquisition path allows the user to observe, prior to automatic steering engagement, the path the vehicle would take from its current state to the destination. The user can then decide whether the predicted acquisition path will interfere with terrain or obstacles that the user wishes to avoid.

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.
