Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (Figure 54). 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 55). 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 54). Repeat this procedure
until the blade is balanced.

Important: The curved part of the blade must be
pointing upward toward the inside of the mower to

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 blades so that they are all side to
side (Figure 56 and Figure 57).
