COUPLING HOOK FOR FARM TRACTORS ABSTRACT OF THE DISCLOSURE A coupling hook for a three-point linkage on a farm tractor includes a coupling jaw or opening for receiving in locking engagement a coupling bolt secured on a piece of farm equipment. Associated with the jaw is a locking bolt mechanism which includes an elongated locking bolt pivotally mounted on a lever with a spring biasing the mechanism into the locking position. In the locking position, the lever mounting the locking bolt is held between a fulcrum and a rear wall on the coupling hook. The locking bolt has a nose-like projection at one end which secures the coupling bolt in locking-engagement. Removing the lever from between the fulcrum and the rear wall releases the locking bolt so that the coupling bolt can be removed from the coupling hook jaw.
