If a grader or loader stalls while performing tasks on the spot and the crew cannot fix the problem at their skill level, a rigger may be called to repair the equipment on the spot rather than tow the heavy equipment back to the maintenance shop. If the rigger cannot fix the problem on the spot, then towing may be used as a last resort.
