ABSTRACT:
A hitch assembly for connecting a towed vehicle to a towing vehicle include a housing mounted on the towing tongue of the towed vehicle having a tow bar mounted in an internal cavity having a restricted throat. Tow bar can be extended and pivoted to position a hitching eyelet on a variably proximately located towed vehicle. The tow arm coacts with the walls of the cavity to provide a torque on the tongue upon forward or rearward movement of the towing vehicle. Upon rearward movement of the towed vehicle, the tow bar attains an aligned nested position in the cavity and a lock assembly is actuated for locking the tow arm to the housing.
