ABSTRACT:
A safety device for maintaining in place a pin connecting the drawbar of a tractor to the tow bar or tongue of a towed piece of equipment. The safety device is mounted on the drawbar and is slideable along the drawbar. An arm extends outwardly from the device, and the device is moved so that the arm is over the top of the drawbar pin when the pin is in place thereby preventing it from becoming disengaged from the drawbar and tongue. A locking pin prevents the safety device from sliding along the drawbar so as to keep it in its pin retaining position.
