ABSTRACT:
A method and apparatus for determining at least one of the pitch and slope of an implement on an earthmoving machine. The apparatus includes a mast connected to an upper corner of the implement, a first set of laser detectors connected to the mast, a second set of laser detectors connected to the mast, a third set of laser detectors connected to the mast, and a computer adapted to receive signals from the first, second, and third sets of laser detectors and responsively determine the angle of pitch and the angle of slope of the implement.
