Brake Maintenance
Servicing the Brakes
Before each use, check the brakes on both a level
surface and slope.
Always set the parking brake when you stop the
machine or leave it unattended. If the parking
brake does not hold securely, see an Authorized
Service Dealer for maintenance.
Checking the Brake
1. Park the machine on a level surface, disengage
the blade control (PTO).
2. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
3. Apply the parking brake. The wheels must lock
when you try to push the machine forward.
4. If the wheels do not lock, see an Authorized
Service Dealer for maintenance.
5. Release the brakes and move the neutral/brake
locks to the neutral position. The wheels
should rotate freely, if not; see an Authorized
Service Dealer for maintenance.
Belt Maintenance
Inspecting the Belts
Inspect all belts every 100 hours.
Check belts for cracks, frayed edges, burn marks
or any other damage. Replace damaged belts.
Replacing the Mower Belt
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.
1. Disengage the PTO, move the motion control
levers to the neutral locked position, 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. Set the mower deck to the 3 inch (76 mm)
height-of-cut setting to allow access and
minimize the belt tension.
4. Remove the 2 bolts and washers in each belt
cover and remove the belt covers (Figure 46).
5. Pull on the idler arm to relieve the belt
tension on the left spindle pulley (Figure 44
or Figure 45).
6. Remove the old belt.
7. Install the new belt around the pulleys
(Figure 44 or Figure 45).
8. Install the belt onto the spring loaded idler
pulley.
