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 hardware fastening the PTO clutch to
the rubber anchor pad.
3. See Figure 33. 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.
4. Loosen the spring compression nut (B, Figure 34) to
release the belt tension.
5. Slide the drive belt over the edge of the idler pulley
and then slide the belt under the idler pulley. Drop
the belt from the PTO clutch pulley groove.
6. Remove the old belt and replace with a new one.
Make sure the V-side of the belt runs in the pulley
grooves (Figure 35).
7. Install the drive belt on the PTO pulley, the spindle
pulleys and idler pulleys. Tighten the spring com-
pression nut (B, Figure 34) until the belt tension
spring (A, Figure 34) is 1-5/8” (4,12cm) long.
8. Reinstall the hardware fastening the clutch to the
rubber anchor pad.
9. 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.
