ABSTRACT:
A towing hitch for attaching a towing vehicle to a towed object includes an arcuate guide attached around the back of the towing vehicle. A traveller, which moves freely along the guide, is hinged to a coupling which is, in turn, rotatably attached to the towed object. Steering the towing vehicle in either a clockwise or counter clockwise direction causes the traveller to move along the guide in the opposite direction, and the steering of the towing vehicle is facilitated. If the hitch includes a drive to power the traveller along the guide, the hitch alone can steer the towing vehicle.
