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.

Height-control device for the elevatable implement of an agricultural

A towed harvesting machine, especially for row crop, has a chassis connected pivotally by a tow bar to a tractor and a fluid-responsive motor connected between the tow bar and the chassis or frame which is capable of laterally shifting the frame or chassis, and hence the mouth of the machine for ensuring alignment of the row crop with the mouth. The mouth of the machine can be provided with sensors controlling this motor, which can be a hydraulic cylinder, to assure this alignment.
