Abstract

An improved tractor draft sensing mechanism of a special construction so designed that it will transmit only draft signals to the tractor draft control linkage. The mechanism includes a rigid sensing arm hinged at one end to a mounting clamp disposed about a bendable shaft, the mounting clamp being provided with set screws which contact a surface of a housing to resist relative rotational movement of the mounting clamp about the bendable shaft.
