5. Push the foot lever forward, pull up on the
transport lock knob and let the deck lower
down to the predetermined cut height by slowly
decreasing foot pressure allowing the foot lever
to travel rearward.
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 motion control
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 mounting
hardware.
6. Place the rollers in one of the positions shown
(Figure 17). Rollers will maintain 3/4 inch (19
mm) clearance to the ground to minimize gouging
and roller wear or damage.
Figure 17
For cutting heights above 3.5 inches (90 mm) use the
bottom hole. The rollers will still be effective against
scalping.
