Operating Guide

• Be sure support jackstand is in the travel position and the coupling is secure. This must

also be retracted so not to interfere while towing. Retract jackstand by removing pin,

pivoting up, and replacing pin.

• Never exceed 15 MPH while towing your grader. Be extra cautious when traveling

over rough terrain.

• Always be careful while backing your grader. You could jackknife your grader if not

careful.

• See tire and wheel specifications for PSI while towing.

• Be aware of the extra length of grader while turning,

parking, crossing intersections, and in all driving situations.
