• i) determining a final position for the tractor;
• ii) calculating a driving path to drive the tractor from the starting position, along the ramp, and to the final position;
• iii) autonomously operating the tractor to drive along the driving path;
• iv) periodically detecting an intermediate position of the tractor via the sensor input, and determining if the intermediate position is located on the driving path, and updating the driving path with a course correction to drive the tractor from the intermediate position to the final position;
• and
• v) stopping the tractor after arriving at the final position.
