Note: For the best performance, install a new blade
before the cutting season begins. During the year, file
down any small nicks to maintain the cutting edge.
DANGER
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator's
or bystander's area, resulting in serious personal
injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
Removing the Blade
Grasp the end of the blade using a rag or a thickly
padded glove. Remove the blade bolt, the lock washer,
the accelerator, and the blade (Figure 30).
Sharpening the Blade
File the top side of the blade to maintain its original
cutting angle (Figure 32A) and inner cutting edge radius
(Figure 32B). The blade will remain balanced if you
remove the same amount of material from both cutting
edges.
1. Sharpen at this angle only. 2. Maintain the original radius
Balancing the Blade
1. Check the balance of the blade by placing the center
hole of the blade over a nail or screwdriver shank
clamped horizontally in a vise (Figure 33).
Note: You can also check the balance using a
commercially manufactured blade balancer.
2. If either end of the blade rotates downward, file that
end (not the cutting edge or the end near the cutting

edge). The blade is properly balanced when neither
end drops.
Installing the Blade
1. Install a sharp, balanced Toro blade, the accelerator,
the lock washer, and the blade bolt. The sail of the
blade must point toward the top of the lawn mower
housing for proper installation. Torque the blade
bolt to 50 ft-lb (68 N·m).
WARNING
Operating the lawn mower without the
accelerator in place can cause the blade to flex,
bend, or break, resulting in serious injury or
death to the operator or bystanders.
Do not operate the lawn mower without the
accelerator.
2. Return the lawn mower to its upright position.
3. Connect the wire to the spark plug.
