Abstract: A hitch assembly for coupling a trailer to a tow vehicle comprises a king ball including a base and a king pin extending vertically from a top surface of the base, the king pin including a ball positioned on a distal end opposite the base, the ball adapted to be pivotally received into a hitch of the trailer. A hitch block includes a draw bar and a housing, the drawbar adapted to be horizontally inserted into a receiver mounted onto the tow vehicle, the housing including a throat adapted to receive the base of the king ball. A locking mechanism is adapted to automatically engage the king pin when the base of the king ball is inserted into the throat of the housing to secure the base of the king ball within the throat of the housing and locking the king ball and the hitch block together.
