BELT REMOVAL & REPLACEMENT
Mower Drive Belt Removal & 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. Remove the hairpin clip and clevis pin and remove
the deck lift foot pedal. Lift the floor plate to gain
access to the PTO drive belt.
3. Loosen the spring compression nut (B, Figure 38) to
release the belt tension.
4. Slide the drive belt over the edge of the spring-
loaded idler pulley and remove belt from all pulley
grooves.
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 39).
6. Install the drive belt on the gearbox pulley, the spin-
dle pulleys and idler pulleys. Tighten the spring com-
pression nut (B, Figure 38) until the belt tension
spring (A, Figure 38) is compressed to 1-5/8”
(4,12cm) long.
7. Run the mower under no-load condition for approxi-
mately 5 minutes to break in the belt.
