Brinly recommends that the hamper be at least 5 inches off the ground. When operating, you want your tow arms to be level to the ground. Once you have leveled the tow bars using the hitch plate, you will need to level the hamper. To level the hamper, find the 4 bolts securing the hamper stop assembly. They should be located at the rear of brush housing assembly. First, loosen. Then move the cross tube UP to raise the hamper or move cross tube DOWN to lower the hamper.
