MOWER BELT REPLACEMENT AND

ADJUSTMENT

PTO Clutch to Deck Belt

1. Park the machine 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 mower deck guard.
3. Remove the rear engine deck guard.
4. Loosen the wing nut (C, Figure 24) to release the
belt tension on the deck drive belt (B).
5. Slide the drive belt over the edge of the spindle pul-
ley and then slide the belt around 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.
7. Install the drive belt on the PTO pulley, the idler pul-
ley and center spindle pulley. Tighten the wing nut
(C, Figure 24) until a 10 lb. (44.5 newton) force is
required to deflect the belt 1/2” (1,27cm) between the
idler pulley and center spindle pulley. Jam hex nut
(D) against anchor. See Figure 23.
8. Run the mower under no-load condition for about 5
minutes to break-in the new belt and re-check belt
tension. Adjust if necessary.

Spindle Belt

1. Remove PTO clutch to Deck belt. See instructions
above.
2. Loosen the nylon nut (C, Figure 25) to release the
belt tension on the spindle drive belt (B).
3. Slide the drive belt over the edge of one of the spin-
dle pulleys and then slide the belt around the idler
pulley and remaining spindle pulleys.
4. Remove the old belt and replace with a new one.
Make sure the V-side of the belt runs in the pulley
grooves (for single v-section belts).
5. Install the spindle drive belt on the spindle pulleys
and the idler pulley. Tighten the nylon nut (C, Figure
25) until a 10 lb. (44.5 newton) force is required to
deflect the belt 1/2” (1,27cm) between the idler pulley
and right-hand spindle pulley. See Figure 25.
6. Run the mower under no-load condition for about 5
minutes to break-in the new belt and re-check belt
tension. Adjust if necessary.
