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.
Test Using the Grass Bag
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
position.
4. Lift the blade control bar to the normal blade
engaged position about one inch (2.5 cm)
below the handle. The bag should begin to
inflate, indicating that the blade is engaged and
rotating.
5. Release the blade control bar. If the bag does
not immediately deflate, it indicates that the
blade is still rotating. The blade brake clutch
may be deteriorating, and, if ignored, could
result in an unsafe operating condition. Have
the lawn mower inspected and serviced by an
Authorized Service Dealer.
