Zusammenfassung:	An improved draft sensing device for a tractor draft control system, the draft sensing device including a tapered load pin having its large end rigidly attached to the tractor and its free end pivotally carrying the tractor draft link through a load arm which imposes a torsional load on the load pin in proportion to the draft load. A bracket secured to the load arm amplifies and measures the load pin motion.
