ABSTRACT:
A tractor has an engine, a torque converter, a lifting device for attachment to an implement such as a plow, the torque converter being controlled automatically whereby if an engine-driven ground wheel starts slipping, the torque converter reduces the tractor's speed. Engine speed and the implement's depth of penetration are also automatically controlled in dependence on the retarding force caused by the implement. In another embodiment, a power take-off shaft is automatically disengaged if the retarding force becomes excessive.
