Abstract
A height adjuster for an agricultural implement, such as the crop pickup device of a field chopper, picker, thresher or like machine having an intake or pickup unit drawing the crop to a chopper or blower, has at least one movable front point or shoe which is swingable about an axis transverse to the direction of travel and rides on the ground. Within this shoe switches are provided to respond to the pivotal movements of the shoe and control a hydraulic cylinder for lifting or lowering the pickup unit to conform to changes in the ground contour.
