ABSTRACT:
A sensor for detecting the height above the soil of harvesting machinery such as a combine header includes an elongated, curved, flexible arm attached at one end to a rotation sensor mounted to the harvester. The sensor arm is concave in an upward direction and includes and outer sheath such as of plastic and an inner metal rod for increased strength to resist breakage such as during turns and when traversing irregular terrain. The arm is positioned forward of, or immediately adjacent to, the lowest part of the harvester which includes a cutter assembly for cutting and separating the crop. As the harvester encounters upraised portions of the soil, the arm's point of contact with the soil moves forward along the arm to provide an increasingly early warning of upraised soil to facilitate early height adjustment and the avoidance of soil contact and possible damage to the harvester.
