  • System for coupling, uncoupling and controlling the header assembly in an agricultural combine
    Patent number: 6519923
    Abstract: A system for coupling, uncoupling and controlling the operating parameters of the header assembly on an agricultural combine. A fixed coupler block on the feeder assembly of the combine is coupled with a movable coupler block on the header assembly to join hydraulic and electrical conduits by rotating a coupler handle to lock the blocks together. As the handle rotates, it also causes push-pull cables to actuate latch pins which mechanically couple the header assembly to the feeder assembly. The system senses whether a header assembly is present or not and, if present, what type of header assembly is present. In the latter case, the system then controls the operating parameters of the header assembly.
