Abstract
A draw pin hitch has a lower jaw, an upper jaw positioned above the lower jaw, and a draw pin receivable generally vertically in apertures in the upper and lower jaws for coupling elements to the hitch between the jaws. The hitch has a pin holding means which is moveable between a “pin raised” position in which the pin is supported by the pin holding means in the aperture of the upper jaw but does not project between the jaws, and a “pin lowered” position in which the holding means allows the pin to extend through both apertures between the jaws. The pin holding means at least partially encircles at least one of the jaws and is moveable between the “pin raised” and “pin lowered” positions by contact of an implement to be coupled to the hitch with a portion of the holding means. When in the “pin raised” position the holding means at least partially extends across the lower end of the aperture in the upper jaw.
