Adjusting the Anti-Scalp Rollers
It is recommended to change the anti-scalp roller
position, when the height of cut has changed.
1. Stop the machine and move the drive levers to
the neutral lock 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 spring disc
washer and bolt (see step 7).
6. Adjust anti-scalp rollers for Normal Operating
Conditions. Place rollers in one of the positions
shown in Figure 8. Rollers will maintain 3/4
inches (19 mm) clearance to the ground to
minimize gouging and roller wear or damage.
Note: For Maximum Deck Flotation, place
rollers one hole position lower. Rollers should
maintain 1/4 inch (6.35 mm) clearance to ground.
Do Not adjust rollers to support the deck. Be
sure roller bolts are installed with the spring disc
washer between head of the bolt and mounting
bracket.
Figure 8
For cutting heights above 3.5 inches (38 mm) use the
bottom hole. The rollers will still be effective against
scalping.
