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 25).
2. Lock the mower deck in the service
position.
Push the mower lift pedal forward
between cutting height number 4 and
number 5 to align the holes in the deck
lift shaft and the deck lift cover. Insert the
cutting height pin in the holes on the side
of the deck lift cover so it passes all the
way through the deck lift cover and
shaft.
IMPORTANT: The mower lift arms are not
locked unless the cutting height adjustment
pin passes all the way through both the deck
lift cover and shaft.
NOTE: Support the mower deck on blocks or
jack stands before disconnecting link chains
from mower lift arms to prevent the deck from
falling.
3. Remove link chains from mower lift
arms. Note hole location on mower lift
arms for replacement.
