ABSTRACT:
A work vehicle for carrying an implement and for tranversing both on-road and off-road surfaces is disclosed. The vehicle has a longitudinal centerline, a left side and a right side. The vehicle includes a frame, a hitch mounted upon the frame for coupling an implement to the vehicle, a moveable ground support device disposed at each side of the vehicle and associated with the frame, and an adjusting apparatus. The hitch allows lateral movement, or sway, with respect to the frame. The moveable ground support devices elevate and support the frame with respect to the surface and allow traversing of the frame with respect to the surface. The adjusting apparatus includes a cam follower coupled to the hitch and a cam coupled to the frame. The cam has a full sway surface, at least one partial sway surface and a substantially no sway surface. The cam moves in a plane substantially parallel to the longitudinal centerline of the vehicle between a full sway position in which the full sway surface faces the cam follower, a partial sway position in which the at least one partial sway surface faces the cam follower and a no sway position in which the no sway surface faces the cam.
