Checking the Blade-stop
System Operation
Service Interval: Before each use or daily
Check that the blades stop within 3 seconds of releasing the
blade-control bar.
Using the Grass Bag
You can use the grass bag to check the blade-stop system.
1. Remove the rear-discharge plug.
2. Install the empty grass bag on the machine.
3. Start the engine.
4. Engage the blade.
Note: The bag should begin to inflate, indicating that
the blades are rotating.
5. While watching the bag, release the blade-control bar.
Note: If the bag does not deflate within 3 seconds of
releasing the blade-control bar, the blade-stop system
may be deteriorating and, if ignored, could result in
an unsafe operating condition. Have the machine
inspected and serviced by an Authorized Service
Dealer.
6. Stop the engine and wait for all moving parts to stop.
Not Using the Grass Bag
1. Move the machine onto a paved surface in a non-windy
area.
2. Set all 4 wheels to the 3-1/2 inch (89 mm) cutting
height setting.
3. Take a half sheet of newspaper and crumple it into a
ball small enough to go under the machine housing
(about 3 inches or 76 mm in diameter).
4. Place the newspaper ball about 5 inches (13 cm) in
front of the machine.
5. Start the engine.
6. Engage the blade.
7. Release the blade-control bar and begin counting out 3
seconds.
8. On the count of 3, push the machine quickly forward
over the newspaper.
9. Stop the engine and wait for all moving parts to stop.
10. Go to the front of the machine and check the
newspaper ball.
Note: If the newspaper ball did not go under the
machine, repeat steps 4 through 10.
11. If the newspaper is unravelled or shredded, the blades
did not stop properly, which could result in an unsafe
operating condition. Contact an Authorized Service
Dealer.
