Mower Drive Belt Removal & Replacement
1. Park the tractor on a smooth, level surface such
as a concrete floor. Disengage the PTO, engage
the parking brake, turn off the engine, and remove
the ignition key.
2. Remove the height adjustment pin (A, Figure 47)
and lower deck.
3. Loosen the 5/16” bolts securing the mower deck
guards and remove the guards.
To avoid damaging belts, DO NOT
PRY BELTS OVER PULLEYS.
WARNING
Use extreme caution when rotating the idler
pulley with the wrench or breaker bar, due to
the increased tension in the spring as the idler
pulley is being rotated. Injury may result if
the wrench is prematurely released while the
spring is under tension.
