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.
