ABSTRACT:
A hitch control system includes a position control lever coupled to a transducer which produces desired position signals, a draft force sensor and a hitch position sensor. A push-button switch is mounted in the control lever housing. A signal processor stores selected values of the sensed draft force in response to actuation of the push-button switch. The signal processor generates position error signals from the desired position and sensed position signals, and generates a load error signal from the sensed draft force and the stored selected draft force values. The hitch is controlled as a function of these errors.
