Mower Belt Replacement

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, remove the ignition key and wait for all moving parts to stop.

2.Remove the mower deck guards.

3.Raise the mower deck to transport position.

WARNING

Use extreme caution when rotating the idler arm with the breaker bar, due to 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.Using a 1/2” breaker bar, place the square end in the square hole located in the idler arm (A, Figure 44). Carefully rotate the breaker bar COUNTER-CLOCKWISE, which will relieve the tension on the belt exerted from the idler arm. Slide the belt off the stationary idler pulley

(B).

5.Carefully release the tension on the breaker bar.

6.Remove the old drive belt and install the new one as shown in Figure 45. Make sure that the V-side of the belt runs in the pulley groves of the spindle pulleys, and that the back of the drive belt must ride against the back-side idler pulleys (B).

7.Install the belt on the PTO pulley, the spindle pulleys and all the idler pulleys except the stationary idler pulley (B, Figure 44). Carefully rotate the breaker bar COUNTER- CLOCKWISE and install the belt on the stationary idler pulley. Carefully release the tension on the breaker bar.

8.Reinstall the mower deck guards.
