Mower Belt Replacement

NOTICE

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.

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.

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 46). 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.

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 47).

5.Install the drive belt on the PTO pulley, the spindle pulleys and all idler pulleys except the stationary pulley (B, Figure 47).

6.Carefully rotate the breaker bar counter-clockwiseand install the belt on the stationary idler pulley (B).

7.Carefully release the tension on the breaker bar.

8.Run the mower under no-load condition for about 5 minutes to break-in the new belt.
