Belt replacement
1. Park the mower on a flat surface and stop the engine.
Make sure deck clutch switch is in the down (OFF)
position. Remove ignition key. Place the steering con-
trol levers in the park brake position. Make sure the
blades are stopped before leaving seat. Disconnect
the negative battery cable.
2. Lower the deck to the lowest setting.
3. Raise the rear of the mower and block with certified
jack stands.
4. Unhook the tension idler spring from the spring mount
to release tension from the deck drive belt.
NOTE: The spring and spring mount will become loose
and can become misplaced. Set these aside after
removal for easier access upon re-assembly. On 36”
decks a tension spring hook (Excel part number
604462) can be used to disconnect the tension idler
spring from the spring mount. Figure 4-12
5. Remove the deck drive belt from the electric clutch
pulley located on the engine shaft. Figure 4-13
NOTE: Do not remove the deck drive belt from the deck
spindle pulleys. It will only need to be removed from the
electric clutch pulley at the rear of the mower.
6. Locate the tension idler spring. Securely clamp locking
pliers onto the spring at the end located next to the
idler arm. Figure 4-13
7. Release the transaxle drive belt tension, using the
locking pliers, to remove the tension spring from the
idler arm. Swing the idler arm out of the way.
