Engine Throttle
The throttle control lever (red knob) is located on the
left side of the seat and is used to control engine
speed. Moving the lever forward toward the FAST
position increases engine speed; moving it back-
ward toward the IDLE position decreases engine
speed.

Forward Speed Control (FSC)
Forward Speed Control (FSC) has two functions:
One is to set forward travel speed, and the other is
to establish the NEUTRAL-PARK position. When
the FSC lever is moved into the FORWARD posi-
tion, a friction lock holds any forward speed setting
from 0 to 8 mph (0 to 12.9 km/h). The ground speed
is proportional to the lever position; the further the
lever is advanced forward, the faster the tractor
moves. It is not necessary to hold the FSC in posi-
tion since the friction lock maintains the selected
lever position. Pulling back on the steering levers
overrides the FSC setting and slows or stops for-
ward travel. Releasing the steering levers allows
the tractor to resume forward travel at the speed set
by the FSC lever. To stop and park the machine, the
FSC lever is moved backward to the NEUTRAL-
PARK position.
Blade Clutch (PTO)
The blade clutch lever is located on the right side of
the seat behind the right fender and is used to en-
gage and disengage the mower blades. The blade
clutch lever has two positions. Pushing the lever
DOWN engages the PTO that drives the mower
blades. Pulling the lever UP disengages the PTO
and engages the blade brake.
Steering Levers
Each drive wheel is controlled by its own indepen-
dent steering lever, for both steering function and
FORWARD/REVERSE motion. The FSC lever sets
the maximum forward speed, and also sets the for-
ward position of the steering levers. The steering
levers operate only with a backward pulling move-
ment of the lever, which causes the drive wheel for
that lever to first slow down, stop, and then reverse
with a full backward lever stroke. The levers are
released to the FORWARD position for “straight-
ahead” ground travel.
NOTE: Pushing forward on the steering levers will
not cause any change in tractor motion - there will
be no steering lever reaction and there will be no
machine damage.
Oil Pressure Warning Horn
The oil pressure warning horn indicates that engine
oil pressure is below the safe operating level [below
3 to 5 PSI (21 to 34 kPa)]. This horn will sound when
the ignition is turned ON, but should go off after the
engine is started. If the horn fails to sound when the
ignition switch is turned ON, it could indicate a horn
failure. If the horn sounds during engine operation,
stop the engine immediately and correct the source
of the problem before further engine operation.
IMPORTANT: Continued operation of the engine
with a low oil pressure condition WILL cause severe
engine damage.
