Abstract:
The described system and method are implemented within a motor grader or other machine for grading of surfaces, wherein the machine includes a ground engaging element, as well as one or more blades for removing surface material. In this context, the described system and method prevent slippage of the ground engaging element against the underlying surface. In an embodiment, a torque limit is applied, wherein the torque limit corresponds to a torque that is less than that required for slippage under the current operating conditions, thus avoiding the problems caused by both overly aggressive and overly conservative cut depth strategies.
