Abstract
A draft load sensing mechanism for a vehicle having a torsion bar carrying the draft load from the lower draft arms which produce a torsion load on the bar. A preload adjusting screw applies a preload torque to the torsion bar and a load limit adjusting screw limits the maximum torque load that can be applied to the torsion bar responsive to the draft load on the vehicle.
