2. Remove the blade bolt and the blade.
Important:
If the blade adapter comes off,
ensure that you install it before installing the
blade and blade bolt. Operating the mower
without the blade adapter will damage the
mower.
Sharpening the Blade
Service Interval:
Every 25 hours
Use a file to sharpen the top side of the blade and
maintain the original cutting angle (Figure 23).

Note:
The blade will remain balanced if you remove the
same amount of material from both cutting edges.
Important:
Check the balance of the blade by
putting it on a blade balancer. You can purchase
an inexpensive balancer at a hardware store. A
balanced blade stays in a horizontal position;
an unbalanced blade settles to the heavy side
(Figure 24). If the blade is not balanced, file more
metal off the cutting edge on the heavy end of the
blade.

Installing the Blade
Service Interval:
Every 2 years
Install a sharp, balanced blade and the blade bolt. The
sail part of the blade must point toward the top of the
mower housing to ensure correct installation. Tighten
the blade bolt to 54 N-m (Figure 22).
Important:
If the blade is excessively worn or
damaged, replace the blade.
