MOWER BELT REPLACEMENT
1. Park the tractor on a smooth, level surface such as a
concrete floor. Disengage the PTO, engage the park-
ing brake, turn off the engine, and remove the ignition
key.
2. Remove the hardware fastening the PTO clutch to the
rubber anchor pad.
3. See Figure 39. Remove the hairpin clip and clevis
pin and remove the deck lift foot pedal. Lift the floor
plate to gain access to the PTO drive belt.
4. 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
counter-clockwise, which will relieve the tension on
the belt exerted from the idler arm.
5. 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 cen-
ter spindle pulley.
6. Remove the old belt and replace with a new one.
Make sure the V-side of the belt runs in the pulley
grooves (Figure 41).
7. Install the drive belt on the PTO pulley, the spindle
pulleys and all idler pulleys except (B, Figure 40).
Carefully rotate the breaker bar counter-clockwise
(see Figure 40) and install the belt on the stationary
idler pulley (B). Carefully release the tension on the
breaker bar.
8. Reinstall the hardware fastening the clutch to the rub-
ber anchor pad.
9. 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.
