(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 25 & 26) 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 27).

7.Install the drive belt on the PTO pulley, the spindle pulleys and idler pulleys. Tighten the spring com- pression nut (B, Figure 25 & 26) until the belt tension spring (A, Figure 25 & 26) 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.
