Checking for Bent Blades
1.
Rotate the blades until the ends face forward and
backward (Figure 64).
Figure 64

1.
Measure from cutting edge to a level surface
2.
Measure from a level surface to the cutting edge,
position A, of the blades (Figure 65). Note this
dimension.
3.
Rotate the opposite ends of the blades forward.
4.
Measure from a level surface to the cutting edge of the
blades at the same position as in step 1. 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.
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
Replace the blades if you hit a solid object or if the blades are
out of balance or 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.
1.
Hold the blade bolt with a wrench.
2.
Remove the nut, blade bolt, curved washer, blade,
spacers, and thin washer from the spindle (Figure 66).

Sharpening the Blades
1.
Use a file to sharpen the cutting edge at both ends of
the blade (Figure 67). Maintain the original angle. The
blade retains its balance if the same amount of material
is removed from both cutting edges.

Sharpen at original angle
2.
Check the balance of the blade by putting it on a blade
balancer (Figure 68). If the blade stays in a horizontal
