This hydraulic cylinder controls the tilt angle of the feeder house on a combine harvester. It extends and retracts to adjust the header pitch relative to the ground, allowing the operator to maintain consistent cutting height across varying terrain. The cylinder is mounted between the feeder house frame and the pivot point of the header attachment. A leaking seal or bent rod causes the header to drift or fail to hold position, reducing cut quality and increasing crop loss. This original component is manufactured to the same bore and stroke dimensions as the original assembly, ensuring the correct extension rate and holding pressure for the hydraulic circuit.
