Removing the Blades
Replace the blades if they hit a solid object, or if the blade is
out of balance or bent.
1. Hold the blade end using a rag or thickly padded glove.
2. Remove the blade bolt, curved washer, and blade from
the spindle shaft (Figure 54).

Sharpening the Blades
1. Use a le to sharpen the cutting edge at both ends of
the blade (Figure 55).
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 56).
Note: If the blade stays in a horizontal position, the
blade is balanced and can be used.
Note: If the blade is not balanced, le some metal off
the end of the sail area only (Figure 55).

3. Repeat this procedure until the blade is balanced.
Installing the Blades
1. Install the blade onto the spindle shaft (Figure 54).
Important: The curved part of the blade must
point 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 54).
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 Checking for Bent Blades (page 39) before continuing.
The mower deck must be leveled side-to-side rst then the
front to rear slope can be adjusted.
Requirements:
• The machine must be on a level surface.
• All tires must be properly inated; refer to Checking the
Tire Pressure (page 38).
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, shut off 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 57).
