MOWER DECKS

Anti-scalp Roller Adjustment

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).

Anti-Scalp rollers are intended to prevent lawn scalping, not

to control cutting height.

For a very high cutting height, set the anti-scalp rollers in the

lowest position on the bracket.

For a very low cutting height, set the anti-scalp rollers in the

highest position on the bracket.

NOTE: There are four anti-scalp rollers on the outside of the

mower deck and four anti-scalp rollers on the inside of the

mower deck. Make sure all anti-scalp rollers are set at the

same height.
