Abstract
A draft force sensor includes a bracket fixed to a tractor frame part. The bracket includes a pair of laterally-spaced legs which support a shaft to which is coupled the fore-end of a draft link. An end of the shaft is coupled to one end of a load strap. The other end of the load strap is pinned at the bracket to allow fore-and-aft loading of the strap from the shaft. A strain sensor is received in an aperture in a central portion of the load strap.
