MOWER BELT REPLACEMENT

To avoid damaging belts, DO NOT
PRY BELTS OVER PULLEYS.
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. Using a 1/2" breaker bar, place the square end in
the square hole located in the end of the idler arm
(A, Figure 56). Carefully rotate the breaker bar
counter-clockwise, which will relieve the tension
on the belt exerted from the idler arm.
3. Slide the drive belt over the edge of the stationary
idler pulley (B). Carefully release the tension on
the breaker bar until the idler arm stops against
the center spindle pulley.
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.
4. Remove the old belt and replace with a new one.
Make sure the V-side of the belt runs in the pulley
grooves (Figure 57).
5. Install the drive belt on the PTO pulley, the spindle
pulleys and all idler pulleys except the stationary
pulley (B, Figure 57). 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.
6. Run the mower under no-load condition for about
5 minutes to break-in the new belt.
