Abstract
A hitch apparatus includes a hitch member defining a substantially vertical drawpin hole. A spacer member is movably mounted to the hitch member such that the spacer member is movable laterally from a working position, where the spacer extends forward to block a rear portion of the drawpin hole, to an idle position where the spacer is removed from the drawpin hole and the front end of the spacer is located lateral to the drawpin. A lock mechanism is operative to selectively maintain the spacer member in the working position and the idle position.
