Abstract
In a slope control system for the working tool of a motor grader or other earth working machine, the slope sensor used for controlling the slope of the tool is mounted on a resolving platform below the front axle pivot of the machine to provide anticipation of the deviations of the machine from the gravity reference. The attitude of the slope sensor is corrected by a factor related to the angle of the tool with respect to the longitudinal axis of the machine.
