4. Rotate the opposite ends of the blades forward.
5. Measure from a level surface to the cutting edge of the
blades at the same position as in step 3 above.
The difference between the dimensions obtained in
steps 3 and 4 must not exceed 1/8 inch (3 mm).
If this dimension exceeds 1/8 inch (3 mm), the blade
is bent and must be replaced; refer to Removing the
Blades, and Installing the Blades, page 33.
Warning
A blade that is bent or damaged could break
apart and could seriously injure or kill you or
bystanders.
Always replace bent or damaged blade with a
new blade.
Never file or create sharp notches in the edges
or surfaces of blade.
Removing the Blades
Blades must be replaced if a solid object is hit, if the blade
is out of balance or is bent. To ensure optimum
performance and continued safety conformance of the
machine, use genuine Toro replacement blades.
Replacement blades made by other manufacturers may
result in non-conformance with safety standards.
Contact with sharp blade can cause serious injury.
Wear gloves or wrap sharp edges of the blade
with a rag.
Hold the blade end using a rag or thickly-padded glove.
Remove the blade bolt, flat washer, split lock washer, and

Sharpening the Blades
When sharpening blade, pieces of blade could be
thrown and cause serious injury.
Wear proper eye protection when sharpening
blade.
1. Use a file to sharpen the cutting edge at both ends of
the blade (Fig. 33). Maintain the original angle. The
blade retains its balance if the same amount of
material is removed from both cutting edges.
2. Check the balance of the blade by putting it on a blade
balancer (Fig. 34). If the blade stays in a horizontal
position, the blade is balanced and can be used. If the
