The parking brake is not adjustable. If the parking brake does
not function properly, do not use the zero-turn rider! See
your dealer to have the parking brake serviced.
Deck Leveling Adjustment
WARNING
Wear heavy gloves when handling or working around
cutting blades. Blades are extremely sharp and can cause
severe injury.
1. Park the unit on a flat, level surface such as a concrete
floor. Engage the parking brake, disengage the PTO, turn
the ignition switch to OFF, and remove the ignition key.
2. Set the mower deck to the 4" (10,2 cm) cutting height.
3. Turn the front caster wheels so that they are facing front-
to-back.
4. Verify that the tires pressures are correct.
• Front: 22 psi (1,72 bar)
• Rear: 12 psi (0,83 bar)
5. Verify that the mower blades are flat, and not bent or
broken. A bent or broken blade must be replaced.
6. Position the two outside mower blades so that they are
facing front-to-back.
7. Measure the distance between the outside tips of the
blades (A, Figure 38) and the ground (B).

• The front measurements (C) should equal 4" (10,2
cm).
• The rear measurements (D) should equal 4-1/4" (10,8
cm).
8. If the measurements do not equal the measurements as
listed above, adjust the deck leveling.
9. Place 2 X 4 blocks under each corner of the mower deck
with the 3-1/2" sides being vertical. Place a 1/4" (0,64 cm)
thick spacer on top of the rear blocks.
10. Loosen the nuts (A, Figure 39) and allow the front of the
deck to rest on the 2 X 4's. Slide the chains in the slots
until the chains are tight and tighten the nuts.

11. Loosen the nuts (B) and allow the rear of the deck to rest
on the 2 X 4's and 1/4" spacers. Slide the chains in the
slots until the chains are tight and tighten the nuts.
12. Repeat the process for the other side of the unit.
13. Remove all blocks and spacers from under the mower
deck.
14. Verify that all four measurements are correct.
Deck Lift Assist Spring
Models are equipped with a deck lift assist spring (A, Figure
40) that assists the operator in raising the mower deck with
the deck lift pedal. The deck lift assist spring is factory set to
provide optimal lifting performance.
