ABSTRACT:
An earth mover blade stabilizing system for maintaining the blade height constant independent of a change in the earth mover's pitch angle. A damped pendulum having a magnetic end moving between two LOHET sensors generates a signal which is used to control the earth mover's hydraulic blade actuation system. An electronic biasing means is provided by which the blade height can be incrementally repositioned to facilitate an automatic grading of a surface to a predetermined slope angle.
