Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (
Figure 50 ).
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 51 ).
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 50 ).

3. Repeat this procedure until the blade is balanced.
Installing the Blades
1. Install the blade onto the spindle shaft ( Figure 49 ).
Important:
The curved part of the blade must be
pointing upward toward the inside of the mower to
ensure proper cutting.
2. Install the blade stiffener (32-inch decks only), the
curved washer (cupped side toward the blade), and the
blade bolt (
Figure 49 ).
3. Torque the blade bolt to 47 to 88 N•m (35 to 65 ft-lb).
Leveling the Mower Deck
Ensure that the mower deck is level any time you install the
mower deck or when you see an uneven cut on your lawn.
Check the mower deck for bent blades prior to leveling;
remove and replace any bent blades; refer to the
Checking for
Bent Blades (page 36) before continuing.
Level the mower deck side-to-side before adjusting the
front-to-rear slope.
Requirements:
•
The machine must be on a level surface.
•
All 4 tires must be properly inflated; refer to Checking
the Tire Pressure (page 35) .
Leveling 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 P
ARK
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 52 ).
