Abstract: The present disclosure is directed to systems and methods for operating a grading machine. The method includes (i) receiving information regarding material on a surface, and the grading machine is configured to travel on the surface and move the material on the surface; (ii) determining a set of parameters for operating the grading machine, and the set of parameters include an articulation angle of the grading machine and a moldboard angle of a moldboard of the grading machine; and (iii) positioning a snow wing and the moldboard of the grading machine based on the set of parameters such that the snow wing has a predetermined spatial relationship with the moldboard.

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.
