Abstract
A system for controlling the elevation of a harvesting unit of a cotton harvester relative to a ground surface. The control system includes a valve assembly whose position controls operation of a lift mechanism connected to the harvesting unit and which is operated by a ground contour sensor assembly carried by the harvesting unit. Harvesting unit elevation is correlated with the extent that the ground contour sensor assembly moves relative to the harvesting unit. The ground contour sensor assembly includes a shoe with a ground engaging surface wherein such surface is movable vertically relative to the harvesting unit and also is pivotable sideways about a fore-and-aft extending axis thereby enhancing ground contact of the sensor assembly with the ground contour.
