Abstract
An earthmoving system includes a laser transmitter for transmitting a reference beam of laser light, and a bulldozer having a laser receiver mounted on the bulldozer for sensing the laser light. The earthmoving system further includes a frame and a cutting blade supported by a blade support extending from the frame. The blade support has a pair of hydraulic cylinders for raising and lowering the blade in relation to the frame. A gyroscopic position sensor senses rotation of the frame about an axis generally transverse to the bulldozer and passing through the center of gravity of the bulldozer. The control is responsive to the laser receiver and to the gyroscopic orientation sensor, and controls the operation of the cylinders and the position of the cutting blade.
