Abstract
A combine including a harvesting head position control system is disclosed herein. The control system includes a position sensor assembly for producing signals representative of the location of the head relative to the combine, operator control switches, and a controller coupled to the position sensor assembly and the operator control switches. The position sensor assembly preferably includes between 3 or more position transducers located along the harvesting head and a comparison circuit. The comparison circuit selects the signal produced by the sensor associated with the smallest distance between the head and ground, and applies this signal to the controller. Based upon the signal, the controller controls the position of the head.
