Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (
Figure 101 ).
Note:
Maintain the original angle.
Note:
The blade retains balance if you remove the
same amount of material from both cutting edges.

1. Sharpen at the original angle
2. Check the balance of the blade by putting it on a blade
balancer (
Figure 102 ).
Note:
If the blade stays in a horizontal position, the
blade is balanced and ready to use.

3. If the blade is not balanced, file some metal off the end
of the sail area only (
Figure 100 ).
4. Repeat this procedure until the blade is balanced.
Installing the Blades
1. Install the blade onto the spindle shaft ( Figure 103 ).
Important:
The curved part of the blade must
point upward toward the inside of the mower to
ensure proper cutting.
2. Install the spring disk and blade bolt ( Figure 103 ).
Note:
Install the spring-disk cone toward the bolt
head.
3. Torque the blade bolt to 115 to 150 N∙m (85 to 110
ft-lb).
