Cutting Blade
Maintenance
Checking and Replacing
the Blades
Service Interval: Before each use or daily—Check
the blades for wear or damage.
When the cutting blades are worn down and no longer
functioning properly, replace them as follows:
Important:
Perform this procedure when the fuel
tank is empty or nearly empty.
1. Shut off the engine, wait for all moving parts to
stop, and remove the spark-plug wire. Engage
the parking brake.
2. Turn the fuel shutoff valve to the O
FF
position,
and drain the fuel from the fuel tank; refer to
Draining the Fuel Tank (page 24) .
3. Remove the 4 bolts, lock washers, and 2
spacers securing the belt cover on the left side
of the machine, and remove the cover.
4. Remove the blade drive belt from the machine.
5. Tilt the machine rearward until the upper handle
rests on the ground, and place a jack stand
under the machine.
Note:
If necessary, use 2 people to tilt the
machine rearward.
CAUTION
Raising the machine and relying solely
on mechanical or hydraulic jacks could
be dangerous. The mechanical or
hydraulic jacks may not provide enough
support or may malfunction allowing the
machine to fall, which could cause injury.
Do not rely solely on mechanical
or hydraulic jacks for support. Use
adequate jack stands or equivalent
support.
6. Lower the cutting blades to the lowest position.
7. Spin the cutting blade assembly. It should spin
freely. If it makes a grinding noise and is halting,
the bearings are worn; replace them when the
blades are replaced.
8. Inspect the blades for damage and wear, and
replace them as required.
DANGER
A worn or damaged blade can break. A
piece of the blade could be thrown into
the area of the operator or a bystander,
resulting in serious personal injury or
death.
• Inspect the blade periodically for wear
or damage.
• Replace a worn or damaged blade.
9. Remove the 4 carriage bolts and locknuts
securing the cutting blade assembly (
Figure 27 ),
and remove it from the fork mounting bracket.
