TRACTOR HITCH Abstract of the Disclosure A hitch system includes a yoke pivotally supported by the ends of a rockshaft extending from the sides of the tractor housing. The yoke includes left and right side panels and a two-piece bottom. A drawbar is pivotally coupled to the yoke between the two bottom pieces. Left and right draft links have fore ends pivotally coupled to the yoke and are sway limited in the down position by sway links connecting each draft link with an inboard portion of the yoke. The draft links are sway limited in the raised position by sway surfaces on the sides of the yoke. Lift arms are splined to the rockshaft ends and are pivoted by a pair of lift cylinders coupled between the lift arms and the housing. A pair of lift links connect the lift arms to the draft links. A yoke positioning and draft sensing link includes a fore end connected to a bottom side of the housing and an aft end connected to the yoke. Draft loads from the draft links and from the drawbar are communicated via the yoke to a draft sensor in the yoke positioning and draft sensing link.
