Adjusting The Cutting Height - Toro 20487 Operator's Manual

14. Pull the lawn 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.
However, to check for a problem with the BBC system
before it affects its normal operation, you may perform
the Special Control Bar Test that follows.
Special Control Bar Test
1. Follow steps 1 through 7 from the Normal Control Bar
Test on page 10.
2. Push the control bar down to its lowest position (Refer
to position B in Fig. 13).
3. Bring the control bar up into the middle position
(about five inches below the handle cross bar) (Refer
to position C in Fig. 14).
Figure 14
Note: This intermediate position (C) is not the normal
operating position of the control bar. However, it helps to
detect a sticking BBC system early enough to prevent an
unsafe condition later.
4. Release the control bar (Refer to position B in Fig. 14).
Note: If you hear a loud "bang", you have raised the
control bar too high. Repeat steps 2 through 4 above, but
do not raise the control bar as high as in step 3.
5. Immediately push the lawn mower over the newspaper
ball.
6. Turn off 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 five inches in front of
the lawn mower (Fig. 10).
B. Start the engine.
C. Follow steps 2 through NO TAG above.
8. Pull the lawn mower away from the newspaper. If the
newspaper ball unravels or is shredded, the BBC
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.
POTENTIAL HAZARD
If the blade brake clutch system is
inoperative, the blade will continue to
rotate when you release the control bar.
Contact with blade could occur.
WHAT CAN HAPPEN
Contact with a rotating blade can cause serious
injury.
HOW TO AVOID THE HAZARD
Check the BBC operation before each use.
Never use a BBC-equipped power lawn
mower with an inoperative safety system.
Take your lawn mower to an Authorized
Service Dealer for repair if a safety system
fails to operate properly.
Control Bar Test Using Optional Rear Bag
If you purchased the optional rear bagging kit, you can
use the grass bag to perform an additional test to check the
blade brake clutch mechanism:
xxxx
1. Install the empty grass bag on the discharge tunnel.
2. Start the engine.
3. Push the control bar (Fig. 11) down to its lowest
position.
4. Lift the control bar to the normal blade engaged
position, about one inch below the handle. The bag
should begin to inflate, indicating that the blade is
engaged and rotating.
5. Release the control bar. If the bag does not
immediately deflate, it indicates that the blade is still
rotating. The blade brake clutch mechanism 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.

Adjusting the Cutting Height

You can adjust the cutting height to five settings (Fig. 15).
for normal cutting, set all four wheels at the same cutting
height.
