Regular Maintenance
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.
NOTICE
To avoid damaging belts, DO NOT pry belts over
pulleys.

4. Using a 1/2” breaker bar, place the square end in
the square hole located in the end of the idler arm
(A, Figure 44). Carefully rotate the breaker bar
CLOCKWISE, which will relieve the tension on the
belt exerted from the idler arm.
5. Slide the PTO drive belt over the edge of the left
spindle pulley (B). Carefully release the tension
on the breaker bar.
6. Remove the old belt and replace with a new one.
Make sure the V-side of the belt runs in the pulley
grooves.
7. Install the PTO drive belt (A, Figure 45) on the
PTO clutch pulley (B), the front idler pulley (C)
and the idler arm pulley (D). Carefully rotate the
breaker bar CLOCKWISE and install the belt on
the left spindle pulley (E). Carefully release the
tension on the breaker bar.
8. Reinstall the mower deck guard.
9. Run the mower under no-load condition for about
5 minutes to break-in the new belt.
