Operation
DANGER
If the blade brake clutch system is
inoperative, the blade will continue to rotate
when you release the blade control bail.
Contact with the blade could occur, causing
serious injury.
• Check the BBC operation before each
use.
• Never use the BBC-equipped lawn mower
with 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
1. Install the empty grass bag on the discharge
tunnel.
2. Start the engine.
3. For units with a Blade Brake Clutch: Push the
blade control lock lever forward to release the
blade control bail (Figure 4).
4. Squeeze the blade control bail against the handle.
5. The bag should begin to inate, indicating that
the blade is engaged and rotating.
6. Release the blade control bail. If the bag does not
immediately deate, 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
The rear wheels are adjusted together with a height
adjustment rod located on the mower housing by
the left rear wheel. The front wheels are adjusted
separately by removing the front wheel shaft
assemblies, adjusting the height, and then replacing
the shaft assemblies. The cutting height can be
adjusted from 1 inch (25 mm) to 4 1/2 inches (114
mm) in 1/2 inch (12.7 mm) increments.
WARNING
Adjusting the cutting height levers could
bring your hands into contact with a moving
blade. A moving blade can cause serious
injury.
• Stop the engine and wait for all movement
to stop before adjusting the cutting
height.
• Do Not put your ngers under the
housing when adjusting the cutting
height.
• Rear Wheel Adjustment:
1. Pull the wheel height adjustment rod upward
to release the pin from the notch in the
adjustment bracket (Figure 16).
