  • Windrow merger with active weight transfer system
    Patent number: 11266071
    Abstract: Windrow mergers employ one or more design features as described herein in connection with a suspension assembly that allows the pickup head to rise or fall relative to a frame of the merger. One feature maintains a substantially constant force or pressure between a pickup head of the merger and the terrain regardless of a height of the head. Another feature maintains a substantially constant hydraulic pressure in a hydraulic actuator that connects the pickup head to a frame assembly of the merger. Still another feature employs a hydraulic pump driven by a power takeoff (PTO) of the tractor to charge and discharge a hydraulic actuator arranged to raise and lower the pickup head of the merger between an upper limit and a lower limit.
