Check Deck Drive Belt
1. Lower the mower deck to its lowest cutting position.
2. Remove the mower deck guards.
3. Make sure the V-side of the belt runs in the pulley
grooves (Figures 14).
4. If the belt is not properly seated, use a 1/2” breaker
bar, and place the square end in the square hole
located in the end of the idler arm (A, Figure 13).
Carefully rotate the breaker bar CLOCKWISE, which
will relieve the tension on the belt exerted from the
idler arm.
5. Re-seat belt and carefully release the tension on the
breaker bar.
6. Reinstall the mower deck guards.
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.
