MOWER BELT REPLACEMENT AND
ADJUSTMENT
(DDSH Models only)
To avoid damaging belts, DO NOT
PRY BELTS OVER PULLEYS.
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 spring compression nut (B, Figure 26 &
27) 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 28).
7. Install the drive belt on the PTO pulley, the spindle
pulleys and idler pulleys. Tighten the spring com-
pression nut (B, Figure 26 & 27) until the belt tension
spring (A, Figure 26 & 27) is 3/4" (1,90cm) long.
8. Run the mower under no-load condition for about 5
minutes to break-in the new belt and re-check spring
length. Adjust if necessary.
