Title: Automatic height control for harvesting machine

Abstract: Automatic height control system for crop pick up reel of peanut combine. The implement is supported at the front on the draught links of a tractor and at the rear on its own ground wheels. A height sensing wheel adjacent the pick-up reel senses ground contours. A linkage of pivotally interconnected links transmits height control signals from the height sensing wheel to the top control link of the tractor's hitch whereby the tractor's draught control system maintains the reel at constant height.
