Removing the Blade
1. Remove the mower; refer to Removing the
Mower, page 37.
2. Carefully tip the mower over.
3. Remove the bolt (5/8” wrench), curved washer,
retainer and blade (Fig. 34). A block of wood
may be wedged between the blade and the
mower to lock the blade when you are removing
the bolt.
4. Inspect all parts. If damage is noticed, install
new parts.

Sharpening the Blade(s)
1. Use a file to sharpen the cutting edge at both
ends of the blade (Fig. 35). Maintain the original
angle. 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 (Fig. 36). 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
procedure until the blade is balanced.

Installing the Blade(s)
1. Install the blade, blade retainer, curved washer
(cupped side toward blade), and the blade bolt
(Fig. 34).
IMPORTANT: The curved part of the blade
must be pointing toward the inside of the
mower to assure proper cutting.
2. Tighten the blade bolt to 45–60 ft-lb
(61–81 Nm).
