Abstract
A tractor draft sensing apparatus capable of sensing only draft forces. This invention is usable with a tractor provided with draft links (14) and includes a mounting member (30) to which the forward end of the draft links are secured by a mounting pin assembly (26), the mounting member in turn being secured by a support pin assembly (36) to a support plate (34) which is in turn secured to the tractor. The center lines of the mounting pin assembly (26) and the support pin assembly (36) lie in a vertical plane. A spring extends away from the support member and one end of it is disposed between restraining assembly (46). Sensing apparatus (72) are disposed adjacent and outwardly of the restraining assembly and is contacted by one end of a sensing arm (66), the other end of which is secured to the mounting member (30). The foregoing structure cancels deflections imposed by heavy draft loads and causes the sensor (72) to respond only to horizontal draft forces.
