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. Ensure that the blade control bar down is in the
lowest position (Figure 17).
3. Push the blade control bar to the right.
4. 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.
5. 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 5 above, but do not raise the blade control
bar as high as in step 4.
6. Immediately push the mower over the newspaper
ball.
7. Stop the engine and wait for all moving parts to
stop.
8. 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 16).
B. Start the engine.
C. Follow steps 2 through 7 above.
9. 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. Ensure that the blade control bar down is in the
lowest position (Figure 17).
4. Push the blade control bar to the right.
5. 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.
6. 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.
