ABSTRACT:
An apparatus for coupling a tractor's three point hitch system to a ground working implement comprises a U-shaped frame mountable at one end to the hitch system and having rearwardly open grooves formed in its other end. An automatically locking and quick release latch assembly is mounted between the walls of the frame and responds automatically to movement of an implement's latch pins into the grooves to capture and lock the latch pins in place so that the implement can be pulled by the tractor. For release of the implement, a simple tug on a cord attached to the latch assembly releases the latch pins of the implement so that the tractor can simply pull away from the decoupled implement.
