More Information
Summary:An automatic hitch mechanism that permits a tractor driver to connect and disconnect an implement without leaving the cab of the tractor. The hitch includes a tractor drawbar equipped with a power-driven slide member, hook member, and power coupling assembly all interconnected for coordinated movement so that during a hitching operation the hook member first swings into operative engagement with the latch ring of an implement and then, in a continuous sequence of automatic steps, the hook member is locked in its operative position, the power coupling assemblies of the tractor and implement are joined together, the jack supporting the implement tongue is retracted, and one of the coupling assemblies is de-stabilized so that thereafter the tractor and implement may execute turns and traverse uneven terrain without damaging or disengaging the coupling assemblies. Automatic unhitching of the tractor and implement involves a reversal in the direction and order of such steps.
