levers outward to the neutral locked position.
2. Disengage the PTO.
3. Engage the park brake.
4. Stop the engine, remove the key and wait for all
moving parts to stop.
5. After adjusting the height of cut, adjust the
anti-scalp rollers by removing the nyloc nut,
bushing, spring disc washer and whizlock nut.
6. Place the rollers in one of the positions shown
(Figure 9). Rollers will maintain 3/4 inch (19 mm)
clearance to the ground to minimize gouging and
roller wear or damage.

bottom hole. The rollers will still be effective against
