Sharpening the Blades
1. Use a file to sharpen the cutting edge at both
ends of the blade (
Figure 52 ).
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 53 ).
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 52 ).

Installing the Blades
1. Install the blade onto the spindle shaft ( Figure
51 ).
Important:
The curved part of the blade
must be pointing 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 51 ).
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.
Check the mower deck for bent blades prior to
leveling; remove and replace any bent blades; refer
to the
Servicing the Cutting Blades (page 42) before
continuing.
Level the mower deck side-to-side first, then adjust
the front to rear slope.
Requirements:
•
The machine must be on a level surface.
•
All tires must be properly inflated; refer to Checking
the Tire Pressure (page 40) .
Leveling from Side to Side
1. Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.
2. 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 the middle position.
4. Carefully rotate the blade(s) so that they are all
side to side (
Figure 54 ).
