Figure 64
1. Cutting Edge
3. Wear/slot Forming
2. Curved Area
2. Inspect the blades, especially the curved area
If you notice any damage, wear, or a slot
forming in this area (Figure 64), immediately
install a new blade.
Checking for Bent Blades
1. Rotate the blades until the ends face forward
and backward (Figure 65). Measure from a
level surface to the cutting edge, position
A
, of
the blades (Figure 65). Note this dimension.
Figure 65
1. Measure here from blade
to hard surface
2. Position A
2. Rotate the opposite ends of the blades forward.
3. Measure from a level surface to the cutting
edge of the blades at the same position as in
step 1 above.
The difference between the dimensions
obtained in steps 1 and 2 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 68).
