Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (
Figure 80 ).
Note:
Maintain the original angle.
Note:
The blade retains balance if the same amount
of material is removed 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 81 ).
Note:
If the blade stays in a horizontal position, the
blade is balanced.

3. If the blade is not balanced, file some metal off the end
of the sail area only (
Figure 79 ).
4. Repeat this procedure until the blade is balanced.
Installing the Blades
1. Install the blade onto the spindle shaft ( Figure 82 ).
Important:
The curved part of the blade must be
pointing upward toward the inside of the mower to
ensure proper cutting.
2. Install the spring disk and blade bolt ( Figure 82 ).
Note:
The spring-disk cone must be installed toward
the bolt head ( Figure 82 ).
3. Torque the blade bolt to 115 to 150 N∙m (85 to
110 ft-lb).
