Abstract
A tow line attachable between a towing vehicle and some other structure has an intermediately positioned spring assembly which substantially reduces jarring and jerking movements. A pair of frame attached cables are directed from the towing vehicle to a tubular conduit and the conduit is fixedly secured to the vehicle bumper hitch. The towing cable is retained within the conduit and is abuttable with an enclosed spring. The tow line compresses the spring within the conduit with the spring then serving to compensate for rapid changes in vehicle velocity.
