ANTI-SCALP ROLLERS
All of the anti-scalp rollers are maintenance free. If any
roller, shaft, or weldment shows excessive wear it
should be replaced.
Anti-scalp rollers are set at the factory for typical
mowing height, but can be adjusted for high or low
cutting conditions (Figure 30).
Rollers are intended to prevent lawn scalping, not to
control cutting height.
Figure 30
For a very high cutting height, set rollers in their lowest
position on bracket.
For a very low cutting height, set rollers in their highest
position on bracket.
All rollers should be set at the same height.

rollers, shut off engine, set parking brake, and
