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.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 38). Carefully rotate the breaker bar clockwise, which will relieve the tension on the belt exerted from the idler arm.

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.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 39).

6.Install the drive belt on the PTO pulley, the spindle pulleys and all idler pulleys except the stationary pulley (B, Figure 38). 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.
