ABSTRACT:
A three-point implement hitch employed to secure an implement forwardly of a propelling tractor. The implement hitch includes a frame on which a pair of forwardly extending lower links are mounted for lateral adjustment. An intermediate portion of each of the lower links may contact a rub block on the hitch frame. The forward ends of each of the lower links rotatably carries an apertured ball which is disposed about a hitch pin on an implement and is secured in place by a lynchpin. When the rearward ends of the lower links are adjusted towards each other and mid-portion of each of the lower links is moved adjacent its associated rub block thus stabilizing the implement and controlling side to side sway. The implement hitch frame can be readily attached to and detached from a tractor.
