Abstract
A control system for the hitch of a tractor includes a motor for moving the mechanical control linkages connected to a hitch control valve, the motor being in the form of an electric motor. The motor is controlled by way of an electrical circuit which includes a main switch, one or more secondary switches which are disposed outside a driving cabin, and a safety switch. The safety switch permits flow of current to the motor only when positional regulation is selected by a hitch control mode selector lever.
