Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (
Figure 52 ). Maintain the original angle. 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 53 ). 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 52 ). Repeat this procedure
until the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft ( Figure 51 ).
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 51 ).
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 (page 39) 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 tire must be properly inflated. Refer to Checking
the Tire Pressure (page 35) .
Leveling from Side to Side
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 blade(s) so that they are all side
to side (
Figure 54 ).

within 5 mm (3/16 inch), an adjustment is required;
continue with this procedure.
