Embodiments of the present invention comprise a system for positioning a drawn implement having a transverse tool bar being pulled by a vehicle traveling generally along a desired path of movement, the vehicle having a mounting hitch on the rear end thereof where a system hitch is configured to adjust its angular orientation and that of the tool bar relative to the vehicle mounting hitch and a global positioning system having an antenna mounted on the system hitch operable to detect the position of the tool bar of the implement relative to the desired path as the vehicle moves generally along the desired path and generate a signal that is indicative of the lateral position of the implement relative to the desired path and means for controlling the hitch means to adjust the angular orientation of the hitch means and the tool bar so that the implement follows the desired path of movement in response to the global positioning system signals.
