Abstract: A hitch system for connecting a towed vehicle to a towing vehicle includes a hitch apparatus attached to the towing vehicle and a control system operably associated with the hitch apparatus. The hitch apparatus includes a frame movably secured to the towing vehicle, and a hitch member secured to the frame that is configured to receive a coupling apparatus of the towed vehicle. The frame is movable relative to the towing vehicle such that the hitch member can be positioned rearward of the towing vehicle at any location within a defined three-dimensional space. The frame is configured to maintain the hitch member in a substantially level orientation at all locations within the three-dimensional space. The control system is configured to move the hitch member to a desired location within the three-dimensional space.
