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. 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 30) to
release the belt tension.
4. Slide the drive belt over the edge of the idler pulley.
Drop the belt from the PTO clutch pulley groove.
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 31).
6. Install the drive belt on the PTO pulley, the spindle
pulleys and idler pulleys. Tighten the spring com-
pression nut (B, Figure 30) until the belt tension
spring (A, Figure 30) is 5/8” long.
7. Run the mower under no-load condition for about 5
minutes.
To avoid damaging belts, DO NOT
PRY BELTS OVER PULLEYS.
