13. Walk around the mower to check for the
newspaper ball. If the ball did not go under the
housing, repeat steps 6 through 12.
14. Pull the mower away from the newspaper. If
the newspaper ball unravels or is shredded,
the blade has not properly stopped, resulting
in an unsafe operating condition. Contact an
Authorized Service Dealer.
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 17).
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 18).
Figure 18
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 18).
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 mower over the
newspaper ball.
6. Stop the engine and wait for all moving parts
to stop.
7. Walk around the mower to check for the
newspaper ball. If the ball did not go under
the housing:
A. Place the ball of newspaper 5 inches (12.7
cm) in front of the mower (Figure 14).
B. Start the engine.
C. Follow steps 2 through 6 above.
8. Pull the mower away from the newspaper. If
the newspaper ball unravels or is shredded,
the blade brake clutch 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 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 operation
before each use.
• Never use a blade brake clutch-equipped
mower with an inoperative safety system.
• Take your 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:
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 mower inspected and serviced by an
Authorized Service Dealer.
