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

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both
ends of the blade
Note:
Maintain the original angle. The blade
remains balanced 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
Note:
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
procedure until the blade is balanced.

mower to ensure proper cutting.

with a thin washer and a nut
