Operation
Note: If the blade does not stop within 3
seconds after releasing the blade control bail,
contact an Authorized Service Dealer.
2. Close the fuel shut-off valve, if equipped with,
when the machine will not be in use for a few
days, when transporting, or when the unit is
parked inside a building.
Using the Self-Propel Drive
(Self-Propelled Units Only)
The lawn mower has three ground speeds: 1 is slow,
2 is medium, and 3 is fast.
1. Start the engine.
2. Using the ground speed control, select the desired
ground speed.
3. Squeeze the drive bail against the handle (see
Figure 4).
Note: Do Not shift speeds while squeezing the
ground speed control against the handle. This
can damage the transmission. Release the ground
speed control before changing speeds.
Note: You can vary the ground speed by
increasing or decreasing the distance between the
ground speed control and the handle. Lower the
control bar to decrease the ground speed when
you are making a turn or if the lawn mower is
moving too fast for you. If you lower the control
bar too far the lawn mower stops self-propelling.
Squeeze the ground speed control closer to the
handle to increase the ground speed. When
you hold the ground speed control tight against
the handle, the lawn mower self-propels at the
maximum ground speed. Move the ground speed
control to the Neutral position when you use the
lawn mower for trimming or whenever you leave
the lawn mower.
Operating the Blade Control Lever
(Blade Brake Clutch Units Only)
1. Start the engine.
2. Squeeze the blade control bail against the handle
(Figure 4).
3. Move the blade control lever to the full forward
Latch position. Blades should engage.
4. Release the blade control bail to disengage the
blades.
Note: The blade control lever will release rapidly
when the blade control bail is released. To avoid
minor injury, keep hands clear of the blade control
lever when the blade control bail is released.
Using the Discharge Tunnel
1. Stop the engine and wait for all moving parts to
stop.
2. Insert the plug. (Refer to Installing the
Discharge Plug section).
3. To remove the plug, move the discharge door
handle rearward and lift up the spring clip on the
bottom of the plug. When the plug is unlocked,
pull it out of the discharge tunnel.
Note: When grass is thick and lush, clippings
may collect on and around the discharge tunnel
plug. This may make removing the plug difcult.
Clean the plug thoroughly after each use.
Checking the Blade Brake Clutch
(Blade Brake Clutch Units Only)
Check the Blade Brake Clutch (BBC) system before
each use to ensure that it is operating properly.
Normal Test:
1. Stop the engine and wait for all moving parts to
stop.
2. Move the lawn mower onto a paved surface in
a non-windy area.
3. Set all four wheels in to the 2 1/2 inches (6.4 cm)
cutting height (see Figure 13).
4. Set the ground speed selector to the N (Neutral)
position.
5. Take a half sheet of newspaper and crumple
it into ball small enough to go under the deck
(about 3 inches or 7.6 cm in diameter) as shown
in Figure 12.
