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 21).
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.
Removing the Mower Deck
1. Remove PTO belt (See Replacing
Mower Belts on page 26).
2. Lock the mower deck in the service
position.
CAUTION: Use care when
releasing idler spring tension.
Keep body parts well away from
idlers when performing this
operation.
