Abstract: A combine has a forward vertically adjustable header or attachment for removing crop material from the field. The header is pivotally mounted on the combine frame and is vertically adjusted by varying the length of a hydraulic cylinder that has one end attached to the header and its other end attached to the combine frame by a pivot pin that includes a force sensor that generates an electric signal proportional to the weight of the header supported by the cylinder. The electric signal provides an input to a control system that controls the flow of hydraulic fluid to and from the hydraulic cylinder.
