3. Test Blade-Brake-Clutch
Control System
The mower is equipped with a blade-
brake-clutch which is designed to stop
the mower blades within three (3)
seconds after release of the Operator
Presence Control or the Blade Drive
Control. Never tamper with, or attempt
to defeat the purpose of this safety
device.
The control system is a mechanical
device which is subject to wear.
Therefore, test the operation of the
blade-brake-clutch control system before
each use of the mower. Refer to "Blade
Brake Control Test" at the end of this
Section.
4. Select Mulching or Side-
Discharge Mowing
You can use the mower either as a
mulching mower or as a side-discharge
mower. To use the mulching feature, in-
sert the mulcher cover as described
below. Remove the mulcher cover to
side-discharge grass clippings. The
mulcher cover is designed to keep the
discharge chute raised up while mowing.
When the cover is removed, the dis-
charge chute will lower itself for side-
discharge mowing.
To install or remove mulcher cover:
1. Stop the engine and wait for all parts
to stop moving. Disconnect the spark
plug wire from the spark plug. Remove
the ignition key on electric start models.
2. To install the cover, insert the right-
side tab of the cover into the front sup-
port bracket (A, Figure 4-1). Insert the
cover into the discharge opening, mak-
ing sure that the slot (B) in the left side
of the cover is completely engaged in the
rear edge of the deck opening.
3. To remove the cover, slide the cover
to the right (front of mower) to disen-
gage the slot (B) from the mower deck
and then pry the left-side of the cover
out and off.
MOVING THE MOWER WITHOUT
ENGINE POWER
The mower can be manually pushed
or pulled by putting the Gear Select
Lever (C, Figure 4-2) in N (neutral) and
pressing and holding the Operator
Presence Control (A, Figure 4-2) down
against the handlebar grip.
To stop the wheels at anytime,
release the Operator Presence Control.
