Sharpening the Blades
1. Use a le to sharpen the cutting edge at both
ends of the blade ( Figure 56 ).
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 57 ).
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 of f the end of the sail area only ( Figure 56 ).

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.
Check the mower deck for bent blades prior to
leveling, and remove and replace any bent blades;
refer to the Servicing the Cutting Blades ( page 40 )
before continuing.
Level the mower deck side-to-side rst; then you can
adjust the front-to-rear slope.
Requirements:
• The machine must be on a level surface.
• All tires must be properly inated; refer to Checking
the T ire Pressure ( page 37 ) .
Checking the Side-to-Side Level
1. Park the machine on a level surface, disengage
the blade-control switch (PT O), and move the
motion-control levers outward to the P ARK
position.
2. Shut of f the engine, remove the key , and wait
for all moving parts to stop before leaving the
operating position.
3. Set the height of cut to 76 mm (3 inches).
4. Carefully rotate the blades side to side.
5. Measure between the outside cutting edges and
the at surface ( Figure 59 ).
Note: If both measurements are not within 5
mm (3/16 inch), an adjustment is required; refer
to Leveling from Side to Side ( page 43 ) .
