摘要： A hitch apparatus includes a frame configured to be secured to a vehicle and that is pivotable about a first axis, a guide that is movably secured to the frame and pivotable about a second axis substantially transverse to the first axis, and a tow bar movably secured to the guide and movable relative to the guide between retracted and extended positions. The hitch apparatus includes a user controlled positioning system with a user input device that is configured to allow a user to extend and retract the tow bar and to articulate the tow bar up-down and left-right so as to position the tow bar distal end at a desired position within a three-dimensional coordinate system.

摘要： A hitch apparatus includes a housing configured to be attached to a vehicle, a tow bar movably disposed within the housing, and a weight distribution apparatus attached to a distal end of the tow bar. The tow bar is movable relative to the housing between retracted and extended positions, and is pivotable relative to the housing when in an extended position. The weight distribution apparatus comprises a hitch member configured to receive a coupling apparatus of a towed vehicle, and at least one weight distributing member configured to extend rearwardly from the vehicle and be attached to the towed vehicle. The hitch member may be any type of coupling apparatus such as a ball coupler, a pintle hook, a cushioned pintle hook, a swivel pintle hook, a lunette ring, and a clevis pin attachment.
