A wheel adjustment system for an agricultural implement includes a controller having a processor and a memory. The processor is configured to receive a first signal indicative of a ground speed of the agricultural implement, receive a second signal indicative of a desired position of a wheel of the agricultural implement, receive a third signal indicative of a current position of the wheel of the agricultural implement, and output a control signal to adjust a position of the wheel of the agricultural implement based on the first signal, the second signal, and the third signal, wherein a rate of adjustment of the position of the wheel varies based on the first signal.

A vehicle (100) for use in the field of visual effects is provided, which has at least one adjustable dimension. The vehicle comprises a frame (101) and a plurality of wheels (110, 120, 130, 140), the wheels being adjustably attached to the frame such that the distance between a pair of wheels can be adjusted either manually or automatically. This adjustment may be a continuous adjustment. The vehicle may also comprise tracking markers which generate data in order to facilitate the production of a digital model. The vehicle may also comprise a camera (155) having a 360 degree field of view. The data captured by the camera can be used in the digital effects process to create realistic reflections of the surrounding environment on the digital model.

A vehicle system includes an axle arrangement operably coupling a wheel assembly with a frame. The frame defines a fore-aft axis and a transverse axis extending generally transverse to the fore-aft axis. The axle arrangement includes first and second axle elements adapted for operative connection between the frame and the wheel assembly for extension and retraction along the transverse axis. The first axle element can be operably coupled with the frame and the second axle element can be integrated with the wheel assembly. One or more sensors can be configured to generate vehicle dat. A computing system can be configured to receive an input related to an adjustment to the position of the second axle element relative to the fore-aft axis and generate an adjustment model based at least partially on the input and the vehicle data.

A working vehicle includes a travel vehicle body, a traveling device to support the travel vehicle body such that the travel vehicle body is allowed to travel, a changer including an actuator to change a track width of the traveling device, and a controller configured or programmed to perform a first change control in which the controller repeats a drive control until the track width satisfies a target value, the drive control being a control to drive the actuator such that the track width reaches the target value. The controller is configured or programmed to perform the drive control and an idle control alternately from when the first change control is started to when the track width satisfies the target value, the idle control being a control to not drive the actuator for an idle time.
