ABSTRACT:
An apparatus facilitating coupling of a trailer to a tow vehicle includes a barrier against which a hitch ball may be positioned in the first stage of a hitching effort. The barrier includes clamps for barrier attachment to the trailer coupling. Support rods and a support plate on the barrier serve to position the barrier rearwardly adjacent the coupler socket. The barrier support plate may be inclined to abut a trailer frame having an inclined frontal surface. To position the trailer coupler laterally into place above a hitch ball, a lever is provided which utilizes the hitch ball as a fulcrum. An arm on the lever is engageable with the coupler to permit the application of force to move the trailer tongue and coupler into place above the hitch ball. Lowering of a trailer mounted jack results in downward engagement with the coupler onto the hitch ball. The barrier and lever are installed and removed without tools.
