Driveline Torque Coupling for Tractor Draft Control 720710

This paper discusses the development of the driveline torque-sensing coupling that is one of the basic components in the “Load Monitor” draft control system for agricultural tractors. Outlined are the design requirements for the torque sensor, the initial concepts considered, the evaluation and testing procedures and results, the evolution of the early prototypes to the current production level, and a concluding section on extensions of the driveline torque-sensing draft control system.
