ABSTRACT:
The towing hitch for attachment to a towing vehicle is disclosed having a hitch member which is selectively shiftable throughout an area of movement thereby requiring only that the coupling element of a trailer be placed within the movement area in order to couple the trailer with the vehicle. The preferred hitch includes a framework for coupling with the towing vehicle, an elongated hitch member, and a coupling assembly coupling the member with the framework for selective axial and pivotal shifting of the hitch member throughout the movement area.
