Mower Belt Replacement

NOTICE
To avoid damaging belts, do NOT pry belts over pulleys.
1. Park the rider 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.
WARNING
Spring loaded components can kick back
causing injury.
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 in
the breaker bar is prematurely release while the spring is
under tension.
3. Using a 1/2" breaker bar, place the square end in the
square hole located in the end of the idler arm (A,
Figure 50).
• 52" Mower Decks: Carefully rotate the breaker bar
clockwise, which will relieve the tension on the belt
exerted from the idler arm.
• 61" Mower Decks: Carefully rotate the breaker bar
counter-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 51).
6. Install the drive belt on the PTO pulley, the spindle
pulleys and all idler pulleys except the stationary pulley
(B, Figure 51).
• 52" Mower Decks: Carefully rotate the breaker
bar clockwise and install the belt on the stationary
idler pulley (B). Carefully release the tension on the
breaker bar.
• 61" Mower Decks: Carefully rotate the breaker
bar counter-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.
