  • Method and apparatus for controlling a work implement
    Patent number: 6286606
    Abstract: A method and apparatus for controlling a work implement movably connected to a work machine. An implement controller automatically controls simultaneous first and second control modes of operation assigned to the work implement. A sensor applies a signal to the implement controller indicating position of the work implement. The implement controller reverses the simultaneous first and second control modes assigned to the work implement upon detecting a predetermined movement of the work movement. The simultaneous first and second control mode assignments may also be changed by actuation of a manually actuatable device.
