Troubleshooting, Adjustments, & Service

ROLLER BAR LEVELING (SELECT MODELS)

The rollers on this Zero Turn unit are not intended to ride on the ground. DO NOT adjust rollers to ride on the ground. Rollers riding on the ground will damage turf and or unit.

1.First level the mower deck using the procedure found in MOWER DECK LEVELING.

2.With the mower installed, place the rider on a smooth, level surface such as a concrete floor. Turn the front wheels so they are straight.

3.Place the mower cutting height pin in the 4th hole from the bottom (C, Figure 30).

4.Measure the distance between the outside ends of the roller bar and the ground. If there is more than 1/8” (3mm) difference between the measurements on each side, proceed to step 5.

5.Locate the roller bar leveling eccentric and locknuts (A, Figure 32). Loosen the locknut and turn the eccentric to raise or lower a side. When the correct level is achieved, hold the eccentric with a wrench and tighten the locknut. Repeat step 4 if necessary.

MOWER BELT REPLACEMENT

To avoid damaging belts, DO NOT

PRY BELTS OVER PULLEYS.

1.Park the rider 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.Raise the mower deck to transport position. Pull the lever (A, Figure 34) towards the rear of the machine to release tension on the mower belt. Secure the lever in the guard notch (B).

3.Remove the old drive belt and install the new one as shown in Figure 33. Note that the back of the drive belt must ride against the back-side idler pulleys (B). Use the belt tension lever (A, Figure 34) to release tension on the idler pulley for installation.
