Abstract
A suspension system is provided that includes an axle configured to support a first wheel on a first lateral end of the axle, and a second wheel on a second lateral end of the axle. The suspension system also includes a steering assembly configured to rotate each wheel relative to the axle about a substantially vertical axis. In addition, the suspension system includes an actuating cylinder extending between the axle and a frame of a work vehicle. The actuating cylinder is configured to transition the frame between a lowered position that enables the steering assembly to rotate each wheel through a first range of motion without contact between the wheels and a component of the work vehicle, and a raised position that enables the steering assembly to rotate the wheels through a second range of motion, greater than the first range of motion.
