Abstract: A fully integrated, three-stage automatic weight distributing hitching system for a trailer and towing vehicle which utilizes a funnel-shaped receiver system (100), a head assembly (D) with elongated shank (160), spring bars (C) and chains (B), and a motorized electromechanical screw-driven piston device (382). The receiver, mounted on the Pear of the towing vehicle, is equipped with spring loaded dogs (140) which drop into machined recesses (240) of the shank when shank is inserted into the receiver, locking the shank in place and creating a secure coupling of the trailer and the towing vehicle. Solenoids (120) are affixed to the outside of the receiver and, when activated, will retract the spring-loaded dogs from the shank, and allow for uncoupling. The forward end of the receiver is fitted with a male portion of an electrical plug (180). The pivotable head assembly with ball (E) and shank extends from the trailer tongue (A).
