Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (
Figure 51 ).
Note:
Maintain the original angle.
Note:
The blade retains its balance if the same amount
of material is removed from both cutting edges.

1. Sharpen at original angle
2. Check the balance of the blade by putting it on a blade
balancer (
Figure 52 ).
Note:
If the blade stays in a horizontal position, the
blade is balanced, and can be used.
Note:
If the blade is not balanced, file some metal off
the end of the sail area only ( Figure 51 ).

3. Repeat this procedure until the blade is balanced.
Installing the Blades
1. Install the blade onto the spindle shaft ( Figure 50 ).
Important:
The curved part of the blade must be
pointing upward toward the inside of the mower to
ensure proper cutting.
2. Install the the curved washer (cupped side toward the
blade) and the blade bolt (
Figure 50 ).
3. Torque the blade bolt to 47 to 88 N-m (35 to 65 ft-lb).
Leveling the Mower Deck
Check to ensure that 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
Servicing the Cutting Blades (page 35) 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 tires must be properly inflated; refer to Checking the
Tire Pressure (page 33) .
Leveling from Side to Side
1. Park the machine on a level surface and disengage the
blade-control switch.
2. Move the motion-control levers outward to the park
position, 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 blade(s) so that they are all side
to side (
Figure 53 ).
