Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends
of the blade (Figure 47). 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 48). 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 47). Repeat this
procedure until the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Figure 46).
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, the curved washer (cupped
side toward the blade) and the blade bolt (Figure 46).
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 tire 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. 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 49 or Figure 50).
