Checking the Blade Brake
Clutch
Check the blade control bar before each use to ensure
that the blade brake clutch system is operating properly.
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. Pull the blade control bar to the normal blade
engaged position. The bag should begin to inflate,
indicating that the blade is engaged and rotating.
4. Release the blade control bail. 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.
If the blade brake clutch system is inoperative,
the blade will continue to rotate when you
release the blade control bail. Contact with
blade could occur, causing serious injury.
• Check the blade brake clutch operation
before each use.
• Never use a mower equipped with a blade
brake clutch that has an inoperative safety
system.
• Take your mower to an Authorized Service
Dealer for repair if the safety system fails to
operate properly.
