Patent abstract
In a motor grader, a total drawbar position may be determined based on signals from various sensors on a drawbar-circle-moldboard (DCM) assembly. The sensors can include rotational sensors for one or both lift arm angles, and one or both yoke primary angles in combination with sensors detecting lengths of the lift cylinders. The sensor information may be used to calculate roll, pitch and yaw angles of the drawbar relative to a frame of the motor grader.
