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 37).
Figure 37
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 anti-scalp cup, and the blade nuts. The sail of the
blade must point toward the top of the lawn mower
housing for proper installation. Torque the blade
nuts to 15 to 27 ft-lb (20 to 37 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.
Cleaning
Cleaning under the Lawn
Mower Housing
To ensure the best performance, keep the underside of
the lawn mower housing clean. Be especially careful to
keep the kickers free of debris (Figure 38).

Washing Method
Service Interval:
Before each use or daily
1. Position the lawn mower on a flat concrete or asphalt
surface near a garden hose.

Note:
The blade will draw in water and wash out
clippings. Let the water run until you no longer see
clippings being washed out from under the housing.
4. Stop the engine and wait for all moving parts to stop.
5. Turn off the water.
6. Start the lawn mower and let it run for a few minutes
to dry out the moisture on the lawn mower and its
components.
