1. Park the unit on a flat, level surface such as a concrete
floor. Disengage the PTO, engage the parking brake, turn
off the ignition, and remove the ignition key.
2. For models equipped with 36" Mower Decks: Remove
the PTO drive belt. See PTO Drive Belt Replacement
(36" Mower Decks) for removal instructions. For models
equipped with 48" mower decks: Remove the mower
deck drive belt. See Mower Deck Drive Belt Replacement
(48" Mower Decks) for removal instructions.
3. Disconnect the wire harness from the PTO clutch (B).
4. Remove the PTO clutch anchor bolt (C).
5. Loosen the jam nut (D) on the spring anchor eye bolt (E).
6. Loosen the adjustment nut (F) on the spring anchor eye
bolt to release the majority of the belt tension.
WARNING
Use extreme caution when rotating the idler arm with the
breaker bar, due to the increased tension in the spring
as the idler arm is being rotated. Injury may result if the
breaker bar is prematurely released while the spring is
under tension.

7. Using a 1/2" breaker bar, place the square end in the
opening in the idler arm (G) and rotate the idler arm
clockwise, which will relieve the tension on the belt
exerted from the idler arm.
8. Slide the drive belt (H) over the edge of the adjustable
idler pulley (I). Carefully release the tension on the
breaker bar.
9. Remove the old belt and replace with a new one. Make
sure that the V-side of the belt runs in the grooves of the
transmission pulleys (J), and the PTO clutch pulley (B).
10. Carefully rotate the breaker bar clockwise and install the
belt on the adjustable idler pulley making sure that the
back side of the belt contacts the face of adjustable idler
pulley.
11. Carefully release the tension on the breaker bar.
12. Re-install the clutch anchor bolt.
13. Turn the adjustment nut until the coil-to-coil measurement
(K) of the spring (L) equals 7" (17,8 cm).
14. Tighten the jam nut.
15. Reconnect the wire harness to the PTO clutch.
16. For models equipped with 36" Mower Decks:
Re-install the PTO drive belt. See PTO Drive Belt
Replacement (36" Mower Decks) for removal instructions.
For models equipped with 48" mower decks: Re-
install the mower deck drive belt. See Mower Deck
Drive Belt Replacement (48" Mower Decks) for removal
instructions.
Operator Platform Suspension
Adjustment
The lower mounting position of the shock assembly linkage
(A, Figure 55) that connects to the operator platform (B)
can be positioned into one of the five available positions
to customize the ride according to the operator's weight
and/or operating conditions. The lower mounting position
closest to the engine (labelled # 1, Figure 55) is for light-
weight operators, which will provide a softer, more cushioned
ride. As the shock assembly linkage is moved towards the
furthest lower mounting position away from the engine deck
(labelled # 5) the machine can accommodate heavier-weight
operators, and provide a stiffer more rigid ride.
