Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends
of the blade (Figure 64). Maintain the original
angle. The blade retains its balance if the same
amount of material is removed from both cutting
edges.

2. Check the balance of the blade by putting it on a
blade balancer (Figure 65). If the blade stays in a
horizontal position, the blade is balanced and can
be used. If the blade is not balanced, file some
metal off the end of the sail area only (Figure 64).
Repeat this procedure until the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Figure 63).
Important:
The curved part of the blade
must be pointing upward toward the inside of
the mower to ensure proper cutting.
2. Install the curved washer (cupped side toward the
blade) and the blade bolt (Figure 63).
3. Torque the blade bolt to 35-65 ft-lb (47-88 N-m).
Leveling the Mower Deck
Check to ensure the mower deck is level any time
you install the mower or when you see an uneven cut
on your lawn.
The mower deck must be checked for bent blades
prior to leveling; any bent blades must be removed
and replaced. Refer to the
Checking for Bent
Blades
procedure before continuing.
The mower deck must be leveled side-to-side first
then the front to rear slope can be adjusted.
Requirements:
•
The machine must be on a level surface.
•
All four tires must be properly inflated. Refer to
Checking the Tire Pressure
in the Drive System
Maintenance section.
Side-to-Side Leveling
1. Park the machine on a level surface and disengage
the blade control switch.
2. Ensure the parking brake is engaged, stop the
engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Set the height-of-cut lever to middle position.
4. Carefully rotate the blades so that they are all side
to side (Figure 66 and Figure 67).
