Lift Assist Adjustment
The list assist springs can be adjusted to
provide more assist or to help make the deck
more stable. Decreasing the amount of force
required to lift the mower deck will increase
the mower deck's bouncing.
Lift assist can be adjusted in two ways:
• Move the spring anchor to a higher
position on the lift arm to increase the
amount of effort required to lift the
deck and reduce any bounce in the
deck.
• Adjust the eyebolt spring anchor on
the frame. Making the spring longer
decreases the amount of force
required to lift the deck.
NOTE: Make sure the lift assist springs are in
the same position and are adjusted to the
same tension on each side of the deck to
prevent cut quality issues.
Moving the anchor point up the lift arm
increases the amount of force required to
lift the deck.

Removing the Mower Deck
1. Remove PTO belt (see Replacing
Mower Belts on page 30).
WARNING: AVOID INJURY. Mower
lift arms and mower lift pedal could
cause severe injury if the lift assist
spring is not disconnected before
disconnecting the lift chains.
Springs store energy. Keep body
parts well away from pinch points
when removing the deck.
NOTE: Support the mower deck on blocks or
jack stands before disconnecting link chains
from mower lift arms to prevent the deck from
falling.
2. Raise the deck to the transport position
and then disconnect the lift assist
springs from the lift arms on each side of
the deck.
3. Slowly lower the deck to its lowest
position.
4. Remove link chains from mower lift
arms.
5. Remove the rear mower mounting pins
connecting the mower mounting arms to
the deck.
6. Slide mower deck out from under unit.
