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
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 60).

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends
of the blade (Figure 61). 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 (Figure 62). 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 (Figure 62). Repeat this
procedure until the blade is balanced.
