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. 44” Models: Using a 1/2” breaker bar, place the
square end in the square hole located in the end
of the idler arm (A, Figures 40). Carefully rotate
the breaker bar clockwise, which will relieve the
tension on the belt exerted from the idler arm.
3. 52” Models: Using a 1/2” breaker bar, place the
square end in the square hole located in the end
of the idler arm (A, Figures 40). 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 41).
6. 44” Models: Install the drive belt on the PTO
pulley, the spindle pulleys and all idler pulleys
except the stationary pulley (B, Figure 40).
Carefully rotate the breaker bar clockwise and
install the belt on the stationary idler pulley (B).
Carefully release the tension on the breaker bar.
6. 52” Models: Install the drive belt on the
PTO pulley, the spindle pulleys and all idler
pulleys except the stationary pulley (B, Figure
40). 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.
To avoid damaging belts, DO NOT
PRY BELTS OVER PULLEYS.
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.
