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 includes an axle having driven wheels each with an associated wheel-speed sensor and the vehicle includes a yaw rate sensor. A controller is programmed to, responsive to a request to reprogram a track width of the driven axle, receive signals from the wheel speed sensors and the yaw rate sensor to learn a track width of the driven axle based on the signals.

The invention relates to a self-propelled agricultural machine, for example a self-propelled merger, said self-propelled agricultural machine being provided with at least one motor, at least one elongated unit for carrying out, in use, an agricultural operation on the land, a first wheel axle and a second wheel axle located at a distance from the first wheel axle, wherein the first wheel axle and/or the second wheel axle is/are to be driven by the motor for moving the agricultural machine, wherein the elongated unit is movable from a transport position to a working position and vice versa, so that the maximum width of the self-propelled agricultural machine in the unit's transport position is less than in the unit's working position.

The invention relates to a chassis comprising a base (12) and four wheels (14) each being mounted on the base by way of a respective supporting device (16) and each being capable of being brought out of a transport position into an operating position of the chassis (10), and vice versa, wherein each supporting device comprises a support or carrier arm (18), which is arranged on the base via a proximal end (20) to be pivotable out of the transport position into the operating position of the chassis, and vice versa, and at a distal end (22) receives an axle journal (24) for rotation, a first control (30) for pivoting the support or carrier arm out of the transport position into the operating position of the chassis, and vice versa, the axle journal rotatably arranged at the distal end of the support or carrier arm, a stub axle (40), which is pivotably arranged on the axle journal and receives the wheel for rotation at a distal end (42) of the axle journal; and a second control (44) for pivoting the stub axle against the axle journal.

A track-width adjustment system, apparatus and method limit track-width adjustments in a self-propelled product applicator, according to a first speed-based protocol for track-width adjustments initiated by an operator of the applicator, and according to a second speed-based protocol for track-width adjustments initiated by an automatic track-width control arrangement of the applicator. An automatic track-width control arrangement continually monitors and adjusts track-width, as required to maintain a desired track-width at substantially any ground speed while the applicator is in motion. Operator initiated adjustments to track-width are allowed only within a prescribed range of ground speeds.

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.
