ABSTRACT:
A tractor draft load sensing apparatus in which a pair of draft links are pivotally connected to opposite end portions of a bar which extends transversely across the tractor and is supported thereon at spaced locations so that draft loads imposed on the links cause flexing of the bar. A tube is rotatably mounted on the bar and extends therealong while draft load signalling means are attached to the tube for rotation therewith. The tube is operatively associated with the tractor so that flexing of the tube, caused by the imposition of draft loads, results in rotation of the tube and hence the signalling means about the bar.
