MOWER BELT REPLACEMENT

Troubleshooting

B

To avoid damaging belts, DO NOTPRY 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

A

ignition key.

 

2. Using a 1/2” breaker bar, place the square end in

52” Deck

the square hole located in the end of the idler arm

 

(A, Figures 49). Carefully rotate the breaker bar

 

counter-clockwise, which will relieve the tension on

A

the belt exerted from the idler arm.

3. Slide the drive belt over the edge of the stationary

B

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 under61” Deck

5. Install the drive belt on the PTO pulley, the spindle

 

 

 

 

pulleys and all idler pulleys except the stationary

 

 

 

 

pulley (B, Figure 49). 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.
