Abstract: A system for re-orienting a machine during a ripping operation includes a position sensing system, a ripper, and a controller. The system stores a ripping path, determines the position of the machine, and compares the position of the machine to the ripping path. A drawbar pull of the machine is determined, compared to a maximum steering drawbar pull, and the ripper is raised if the machine is positioned greater than a predetermined distance from the ripping path and the drawbar pull exceeds the maximum steering drawbar pull. The machine is re-oriented and the ripper lowered relative to the work surface.
