Adjusting the Anti-Scalp Rollers
Whenever you change the height of cut, adjust the height of the anti-scalp rollers.
1. Park the machine on a level surface, disengage the blade-control switch, and move the
motion-control levers outward to the P
ARK position.
2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving
the operating position.
3. Adjust the anti-scalp rollers to match the closest height-of-cut position.
Note: Adjust the anti-scalp rollers so that the rollers do not touch the ground in normal,
flat mowing areas.

Operating Tips
Maximize Air Circulation
For best mowing and maximum air circulation, operate the engine at the FAST position. Air
circulation is required to thoroughly cut grass clippings, so do not set the height-of-cut so low
as to totally surround the mower deck in uncut grass. Always try to have 1 side of the mower
deck free from uncut grass, which allows air to be drawn into the mower deck.
Avoid Cutting Too Low
When mowing uneven ground, raise the cutting height to slightly higher than normal to avoid
scalping the turf. However, the cutting height used in the past is generally the best one to
use. When cutting grass longer than 15 cm (6 inches) tall, you may want to cut the lawn
twice to ensure an acceptable quality of cut.
Cut a Third of the Grass Blade
It is best to cut only about a third of the grass blade. Cutting more than that is not
recommended unless grass is sparse, or it is late fall when grass grows more slowly.
Alternate the Mowing Direction
Alternate the mowing direction to keep the grass standing straight. This also helps disperse
clippings, which enhances decomposition and fertilization.
