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 36).
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.

Lift Assist Adjustment
(Figure 38)
The deck lift assist springs are adjusted to
reduce lift effort or to increase deck stability.
To adjust the force required to lift the deck:
1. Loosen the jam nut (1) on the lift assist
spring anchor bolt.
2. Adjust the spring anchor to the desired
setting:
• Loosen the spring anchor (turn
counter-clockwise) to decrease spring
tension and increase the effort
required to raise and lower the deck.
This will also add stability to the deck.
• Tighten the spring anchor (turn
clockwise) to increase spring tension
and decrease the effort required to
raise and lower the deck.
IMPORTANT: Excessive spring tension will
make the deck more likely to lift and bounce
off the turf when the mower travels over
rough terrain.
3. Repeat for the other side of the deck.
4. Measure the distances between the end
of the assist springs and the trunnions
on both sides. Ensure that both assist
springs are adjusted to the same
dimension.
NOTE: Lift springs must be adjusted to the
same tension on each side of the deck to
prevent cut quality issues.
