2.
Use the
Deck Belt Tensioning Spring Length chart to
determine the correct spring length for your unit.
3.
Measure the coil length (A, Figure 55) of the mower belt
tensioning spring (B). The measurement should equal the
measurement as indicated in the chart. If not, continue with
step #4.

4.
Loosen the jam nut (C) on the eyebolt (D).
5.
Turn the adjustment nut (E) until the measurement as
indicated in the chart is achieved.
6.
Re-tighten the jam nut.
7.
Re-install the mower deck guards.
Transaxle Drive Belt Replacement
Figure 56 depicts the transmission drive belt as seen from
underneath the unit and looking up at it. The arrow (A, Figure
56) indicates the front of the unit.

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.
Remove the mower deck drive belt. See
Mower Deck Drive
Belt Replacement for removal instructions.
3.
Disconnect the wire harness from the PTO clutch (B).
4.
Loosen the hardware that secures the PTO clutch anchor
(C) to the engine deck and rotate the PTO clutch anchor
away from the slot in the PTO clutch.
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 stationary 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), PTO clutch pulley (B), and the
adjustable idler pulley (K).
10. Carefully rotate the breaker bar clockwise and install the
belt on the stationary idler pulley making sure that the back
side of the belt contacts the face of stationary idler pulley.
11. Carefully release the tension on the breaker bar.
12. Reposition the PTO clutch anchor into the slot of the PTO
clutch and tighten it’s hardware to secure it in place.
13. Turn the adjustment nut until the coil-to-coil measurement
(L) of the spring (M) equals 3-1/4" (8,3 cm).
14. Tighten the jam nut.
15. Reconnect the wire harness to the PTO clutch.
16. Re-install the mower deck drive belt. See
Mower Deck Drive
Belt for re-installation instructions.
Operator Platform Suspension Adjustment
The lower mounting position of the shock assembly linkage (A,
Figure 57) 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 57) 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
