newspaper ball. If the ball did not go under the
deck, repeat steps 6 through 12.

To check for a problem with the blade brake clutch
system before it affects its normal operation, you can
perform the Special Test that follows.
Special Test
1. Follow steps 1 through 7 from the Normal Test.
2. Move the blade control bar down to its lowest
position (Position B in Figure 19).
3. Bring the blade control bar up into the middle
position about 5 inches (12.7 cm) below the handle
cross bar (Position C in Figure 20).
Figure 20
Note: This intermediate position (C) is not the
normal operating position of the blade control bar.
However, it helps to detect a sticking blade brake
clutch system early enough to prevent an unsafe
condition later.
4. Release the blade control bar (Position B in
Figure 20).
Note: If you hear a loud "bang," you have raised
the blade control bar too high. Repeat steps 2
through 4 above, but do not raise the blade control
bar as high as in step 3.
5. Immediately push the lawn mower over the
newspaper ball.
6. Stop the engine and wait for all moving parts to
stop.
7. Walk around the lawn mower to check for the
newspaper ball. If the ball did not go under the
deck:
A. Place the ball of newspaper 5 inches (12.7 cm)
in front of the lawn mower (Figure 16).
B. Start the engine.
C. Follow steps 2 through 6 above.
8. Pull the lawn mower away from the newspaper.
If the newspaper ball unravels or is shredded,
the blade brake clutch system system could be
deteriorating to the point where it could result in an
unsafe operating condition. Contact an Authorized
Service Dealer for an inspection and repair of your
lawn mower.
If the blade brake clutch system is inoperative,
the blade will continue to rotate when you
release the blade control bar. Contact with
blade could occur, causing serious injury.
• Check the blade brake clutch system
operation before each use.
• Never use a lawn mower equipped with a
blade brake clutch that has an inoperative
safety system.
• Take your lawn mower to an Authorized
Service Dealer for repair if the safety system
fails to operate properly.

You can use the grass bag to perform an additional test
to check the blade brake clutch mechanism:
1. Install the empty grass bag on the discharge tunnel.
2. Start the engine.
3. Push the blade control bar down to its lowest
