MOWER DECKS
Adjusting Anti-Scalp Rollers
The anti-scalp rollers are set at the factory for typical
mowing height, but can be adjusted for high or low
cutting conditions (Figure 18).
Rollers are intended to prevent lawn scalping, not to
control cutting height.
For a very high cutting height, set the rollers in their
lowest position on the bracket.
For a very low cutting height, set the rollers in their
highest position on the bracket.
All rollers should be set at the same height.
CAUTION: Use care when releasing idler spring
tension. Keep body parts well away from idlers
when performing this operation.
