to hard surface
2. Position A
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 .
The difference between the dimensions obtained in
steps
3 and 4 must not exceed 3 mm (1/8 inch). If this
dimension exceeds 3 mm (1/8 inch), the blade is bent
and must be replaced; refer to
Removing the Blades
(page 61) and Installing the Blades (page 62) .
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
You must replace the blade 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.
WARNING
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 thick padded glove.
2. Remove the blade bolt, curved washer, and blade from
the spindle shaft (
Figure 88 ).
Sharpening the Blades
WARNING
When sharpening blades, pieces of the blade could
be thrown and cause serious injury.
Wear proper eye protection when sharpening
blades.
1. Use a file to sharpen the cutting edge at both ends of
the blade (
Figure 86 ). Maintain the original angle. The
blade retains its balance if the same amount of material
is removed from both cutting edges.
Figure 86
1. Sharpen at original angle
2. Check the balance of the blade by putting it on a blade
balancer (
Figure 87 ). If the blade stays in a horizontal
position, the blade is balanced and you can use it. If
the blade is not balanced, file some metal off the end
of the sail area only (
Figure 88 ). Repeat this procedure
until the blade is balanced.
