Important:
If the shear pins are broken, the mower
belt may be damaged. Inspect the belt; refer to
Adjusting the Blade Drive Belt.
Removing the Blades
1. Remove the mower; refer to Removing the Mower.
2. Carefully tip the mower over.
3. Remove the bolts, washers, and blades (Figure 39).
Wedge a block of wood between each blade and the
mower to lock the blade when you are removing
each bolt.
Note:
The right blade has a left-hand threaded bolt.
4. Inspect all parts; replace any that are worn or
damaged.
Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
each blade (Figure 40). Maintain the original angle.
The blade retains its balance if you remove the same
amount of material from both cutting edges.

1. Sharpen at original angle
2. Check the balance of each blade by putting it on
a blade balancer (Figure 41). If the blade stays in a
horizontal position, the blade is balanced and can be
used. If the blade is not balanced, file some metal
off the back side of the blade. Repeat this step until
each blade is balanced.

ensure proper cutting.

(Figure 42).
