A draw pin assembly (10) includes a hammer strap (14) that mounts on the drawbar (12) and a draw pin (40) that extends through aligned draw pin holes (32,34) in the hammer strap (14) and drawbar (12). A latch mechanism supports the draw pin (40) in a retracted position while a trigger (56) in the hitch-receiving space (39) of the assembly releases the latch when a towed implement hitch comes into the proper alignment with the draw pin. An automatic locking mechanism is used to lock the draw pin (40) against inadvertent release. In one embodiment, the draw pin is fully recessed into the hammer strap when set and the latch and locking functions are provided by a loop type handle (44) connected to the draw pin. This eliminates any elements projecting above the hammer strap (14) to maximize the clearance for a tractor power takeoff. <IMAGE> |
