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 25).
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.
CAUTION: Use care when releasing
idler spring tension. Keep body parts
well away from idlers when
performing this operation.
