A vehicle includes a chassis, a plurality of ground engaging elements supporting the chassis above a ground surface, a motor for driving at least one of the ground engaging elements to thereby propel the machine along the ground surface, and a chassis height adjustment system for selectively raising and lowering the chassis relative to the ground surface. A track width adjustment system is configured to shift the position of at least one of the ground engaging elements laterally relative to the chassis and a controller is configured to automatically actuate the track width adjustment system when the chassis height adjustment system is actuated to preserve a constant track width as the chassis moves up and down relative to the ground surface. |
