MEASURE FROM CUTTING
EDGE TO A LEVEL SURFACE
Figure 31
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 above. The
difference between the dimensions obtained in steps 1
and 2 must not exceed 1/8 in. (3 mm).
Note: If this dimension exceeds 1/8 in. (3 mm), the
blade is bent and must be replaced. 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 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 a blade is
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, cone washer, blade,
spacers, and thin washer from the spindle (Fig. 32).

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of the
blade (Fig. 33). 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 (Fig. 34). 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 (Fig. 33). Repeat this step until the blade
is balanced.
