POTENTIAL HAZARD
A blade that is bent or damaged could
break apart and pieces could be thrown at
bystanders or at you as you use the mower.
WHAT CAN HAPPEN
Pieces of blade that may be thrown could
seriously injure or kill you or bystanders.
HOW TO AVOID THE HAZARD
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.
Hold the blade end using a rag or thickly-padded
glove. Remove the blade bolt, flat washer, split
lockwasher and blade from the spindle shaft (Fig. 20).

Sharpening the Blades
1.
Use a file to sharpen the cutting edge at both
ends of the blade (Fig. 21). Maintain the original
angle. The blade retains its balance if the same
amount of material is removed from both cutting
edges.

Check the balance of the blade by putting it on a
blade balancer (Fig. 22). 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. 20).
Repeat this procedure until the blade is balanced.

Installing the Blades
1.
Install the blade onto the spindle shaft (Fig. 20).
IMPORTANT: The curved part of the blade
must be pointing upward toward the inside of
the mower to ensure proper cutting.
2.
Install the flat washer, lock washer and blade
bolt (Fig. 20). Torque the blade bolt to 85–110
ft-lb (115–150 N m).
