Abstract
A system and method for automatically controlling the position of a work implement movably connected to a work machine and maintaining the work implement at a preselected slope of cut relative to a geographic surface is provided. The system has first and second receiving devices mounted on the work implement for receiving position signals from a plurality of remote locations. A processor determines the actual slope of cut of the work implement based on the received position signals. An implement controller delivers an implement control signal in response to a difference between the actual and a preselected desired slope of cut of the work implement. An implement control system elevationally changes the slope of cut of the work implement at an automatic mode of operation of the system. The system is particularly suited for use on a geographic surface altering work machine.
