1. Measure here from blade
to hard surface
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.
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 a sharp blade can cause serious
injury.
Wear gloves or wrap sharp edges of the blade
with a rag.
1. Hold the blade end using a rag or thickly-padded
glove.
2. Remove the blade bolt, spring disk and blade from
the spindle shaft (Figure 80).
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 (Figure 78). 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 (Figure 79). 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 end of the sail area only (Figure 80). Repeat this
procedure until the blade is balanced.
