2. Measure from a level surface to the cutting
edges at locations
A and B ( Figure 40 ), and
record both dimensions.
3. Rotate the blades so that their opposite ends
are at locations
A and B ( Figure 40 ).
4. Repeat the measurements in step 2 and record
them.
Note:
If the difference between the dimensions
A and B obtained in steps 2 and 4 exceeds 3
mm (1/8 inch), the blade is bent and you will
need to replace it. Refer to
Removing the Blades
(page 29) and Installing the Blades (page 30) .
WARNING
A blade that is bent or damaged could break
apart and could seriously injure or kill you or
bystanders.
• Always replace a bent or damaged blade
with a new blade.
• Never file or create sharp notches in the
edges or surfaces of a blade.
Removing the Blades
Replace the blades when the machine hits a solid
object or when a blade is out of balance or bent. Use
only genuine Toro replacement blades.
1. Use a block of wood to hold each blade steady
and turn the blade bolt counterclockwise as
shown in
