Mower Deck Drive Belt Replacement
NOTICE To avoid damaging belts, do NOT pry belts over
pulleys.
1.
Park the unit on a flat level surface such as a concrete floor.
Disengage the PTO, engage the parking brake, turn the
ignition switch to OFF and remove the key.
2.
Lower the mower deck to its lowest cutting position and
remove 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.
3.
Using a 1/2" breaker bar, place the square end in the square
hole located in the end of the idler arm (A, Figure 37),
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 rear 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
that the V-side of the belt runs in the pulley grooves.
6.
Install the drive belt (A, Figures 38 & 39) on the PTO pulley,
the spindle pulleys (B), the front stationary idler pulley(s)
(C), and the adjustable idler pulley (D).
