SERVICE AND MAINTENANCE

Remove the hex screw (a) and the blade bell support (b) which holds the
blade (c) and the blade adapter (d) to the deck motor. See Figure 24.
4.
Remove blade (c) and adapter (d) from the deck motor spindle. See Figure 24.
5.
To properly sharpen the cutting
blade, remove equal amounts
of metal from both ends of the
blade along the cutting edges,
parallel to the trailing edge, at a
25°- to 30° angle. Always grind
each cutting blade edge equally
to maintain proper blade
balance. See Figure 25.
6.
Test the blade’s balance using
a blade balancer. Grind metal
from the heavy side until it
balances evenly.
WARNING
A poorly balanced blade will cause excessive vibration, may damage
the riding mower and/or result in personal injury.
NOTE:
When replacing the blade, be sure to install the blade with the side of
the blade marked ‘‘Bottom’’ (or with a part number stamped in it) facing the
ground when the riding mower is in the operating position.
7.
Reinstall blade when properly sharpened. Torque to 450-600 in-lbs (50.9
-
67.8 N-m).
Off-Season Storage
Storing the Riding Mower
•
Allow the machine to cool in an open area before storing.
•
Do not park the riding mower near any flammable materials (wood, cloth or
chemicals) or any open flames or other potential source of ignition (furnace,
water heater or any other type of heater).
•
Remove all combustible materials from the riding mower before storing.
Empty cargo boxes, grass catchers or containers.
Removing the Riding Mower from Storage
1.
Fully charge the battery and inflate the tires to the recommended pressures.
Figure 25
2.
Drive the riding mower without a load to make certain all the riding mower
systems are functioning properly.
Battery Storage
1.
The battery should be stored with a full charge. A discharged battery can
freeze faster than a charged battery in cold temperatures.
2.
The battery charger should remain connected to the charging port on the
riding mower when not in use.
3.
If keeping the charger connected during off-season storage is not possible,
the battery should be fully charged once every month.
NOTE:
It will take approximately 4 hours to fully charge the battery. Leaving
the battery connected to the charger for more than 4 hours will not damage
the battery.
4.
Battery should not be kept in a discharged state. Permanent damage to the
battery can occur.
5.
Fully recharge the battery before returning to service.
