A vehicle includes an operator station, a propulsion system, a steering system a hitch, and a vehicle positioning system. The positioning system includes positioning controls outside the operator station of the vehicle and adjacent to the hitch, such as on a rear fender. The positioning controls include a forward switch, a reverse switch, a left switch and a right switch. A controller is connected to the positioning controls, to the propulsion and steering systems. The controller moves the vehicle forward or rearward in response to actuation of the forward or reverse switches. The controller operates the steering system in response to actuation of the left or right switches. The steering system may include a brake control valve which brakes one of a pair of driven wheels while the other driven wheel is rotating. The steering system may include a steering control valve which is operable to turn steerable wheels.
