If the gap between the brake bar and tire is not correct, an
adjustment is required.
1. Park the machine on a level surface and disengage the
PTO, and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Release the parking brake; refer to Releasing the
Parking Brake (page 18).
4. To adjust the brake, remove clevis pin and hairpin-cotter
pin from the lower-brake lever and yoke (Figure 63).

Note: The distance between the brake bar and the tire
needs be between 3 and 6 mm (1/8 and 1/4 inches).

Belt Maintenance

Checking the Belts

Service Interval: Every 100 hours—Check the pump-drive
belt.
Every 100 hours—Check the mower-deck belt(s).
Check belts for cracks, frayed edges, burn marks, wear, signs
of overheating or any other damage.
The signs of a worn mower belt are squealing while the belt
is rotating, blades slipping while you are cutting grass, frayed
belt edges, burn marks, and cracks. Replace the mower belt if
you detect any of these signs.
Replacing the Mower-deck
Belt for 91 cm Mowers
Important: The fasteners on the covers of this machine
are designed to remain on the cover after removal.
Loosen all of the fasteners on each cover a few turns so
that the cover is loose but still attached, then go back
and loosen them until the cover comes free. This will
prevent you from accidentally stripping the bolts free
of the retainers.
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Loosen the bolts and remove the right belt cover with
the bolt attached to it.
4. Remove the spring from the anchor post on the
idler-pulley arm (Figure 64).
5. Remove the worn mower belt (Figure 64).
6. Install the new mower belt around the clutch pulley, the
deck pulleys, and the idler pulley (Figure 64 ).
7. Install the spring onto the anchor post on the
idler-pulley arm (Figure 64 ).
8. Install the belt cover onto the cutting unit and secure
the bolt.
