MOWER BELT 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. 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 41). 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. Remove the old belt and replace with a new one.
Make sure the V-side of the belt runs in the pulley
grooves (Figure 42).
6. Install the drive belt on the PTO pulley, the spindle
pulleys and all idler pulleys except the stationary
pulley (B, Figure 41). Carefully rotate the breaker
bar clockwise and install the belt on the stationary
idler pulley (B). Carefully release the tension on
the breaker bar.
7. Reinstall the mower deck guards.
8. Run the mower under no-load condition for about
5 minutes to break-in the new belt.
To avoid damaging belts, DO NOT
PRY BELTS OVER PULLEYS.
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.
