Abstract
A system and method is provided for determining the magnitude and direction of the draft force applied to the drawbar of a tractor by a towed implement. Orthogonal load sensors can be placed at the drawbar pivot point to measure load on the drawbar. From the measured load on the drawbar, the lateral and longitudinal draft forces applied by the towed implement on the drawbar can be calculated. The magnitude and direction of the draft force can then be determined from the calculated lateral and longitudinal forces.
