Mower Belt Replacement
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 41). Carefully rotate the breaker bar counter-
clockwise, which will relieve the tension on the belt
exerted from the idler arm.
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 42).
6. Install the drive belt on the PTO pulley, the spindle
pulleys and all idler pulleys except the stationary pulley
(B, Figure 41). 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.
7. Reinstall the mower deck guards.
8. Run the mower under no-load condition for about 5
minutes to break-in the new belt.
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.
