Blade Sharpening
WARNING
!
To avoid serious injury or death:
Wear eye protection and gloves while inspecting, removing,
sharpening, and replacing a blade.
1. A cutting blade should be replaced or sharpened if it
is dull or nicked.
2. Clean blade washer and blade mounting surface
before installing a new blade. Also clean the old
blade if you plan to sharpen it for reuse.
Refer to Figure 5-6:
3. Maintain sharpness by grinding only the top of the
cutting edge at the same bevel as the original edge.

Refer to Figure 5-7:
4. Check blade balance by positioning the blade
horizontally on a nail or shaft through the blade’s
center hole. If either end of blade rotates downward,
grind (remove) metal on that end until blade will
balance horizontally on the nail. The blade is
properly balanced when neither end drops. Balance
of a blade is generally maintained by removing an
equal amount of material from each end of the blade.

Driveline Protection
DANGER
!
To avoid serious injury or death:
Always disconnect driveline from the tractor before servicing
the drivetrain and components powered by the drivetrain. A
person can become entangled in the drivetrain if the tractor is
started and the power take-off is engaged.
WARNING
!
To avoid serious injury or death:
A slip clutch that has been in use or has slipped for as little as
only two or three seconds during run-in may be too hot to
touch. Allow a hot clutch to cool before working on it.
The drivetrain and mower is protected from shock loads
with a friction slip clutch on the main driveline. Oxidation
caused by moisture and condensation on the clutch
friction surfaces can seize the inner frictions plates. To
remove oxidation, run the clutches through a “run-in”
cycle prior to initial operation, at the start of each season,
and when the clutch has not be used for approximately
60 days.

implement.
6. From the tractor seat, start the tractor, and set the
engine speed at half throttle.
7. Cycle the clutch on and off 5 or 6 times (15 seconds
