Mower Belt Replacement - 36” Deck Models
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. Lower the mower deck to its lowest cutting position and
remove the mower deck guards.
3. Using a 1/2” breaker bar, place the square end in the
square hole located in the end of the idler arm (A,
Figures 40). Carefully rotate the breaker bar
CLOCKWISE, which will relieve the tension on the belt
exerted from the idler arm.
4. Slide the drive belt over the edge of the stationary idler
pulley (B). Carefully release the tension on the breaker
bar.
5. Loosen the hardware that secures the stationary idler
pulley and the chevron belt idler pulley (B & C) to the
cutter deck and slide both pulleys forward towards the
front of the deck. Remove the old chevron belt.
Remove the old deck drive belt.
6. Install the deck drive belt on the PTO pulley, the spindle
pulley and the adjustable idler pulley. Do not install the
deck drive belt on the stationary idler pulley (B, Figure
41) at this time.
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.
NOTICE
To avoid damaging belts, DO NOT PRY BELTS OVER
PULLEYS.
