Abstract: A height control system is disclosed for use on a harvester and includes at least one lightweight wheel which rides over the crop being harvested at a location forwardly of the vehicle in an undisturbed area of the crop without damaging the crop. The wheel detects upward or downward inclined portions of the ground and controls power means which raises or lowers at least one plant handling component of the harvester for maintaining the component at the desired elevation relative to the ground. The system also includes control means which sense varying ground speed and prevents undesirable jerky raising and lowering of the conveying components in response to the wheel riding over small articles such as rocks at different speeds.
