Abstract

A method and apparatus for controlling a work implement moveably 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 implement controller also automatically moves the work implement from a first rotational position to a second, mirror image rotational position upon operator actuation of a manually actuatable device. The simultaneous first and second control mode assignments may also be changed by actuation of the manually actuatable device.
