Operating Instructions

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.
Throttle Choke
Choke and Throttle Location
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 6.5 mph (0 to 10.5 km/h). The ground
speed is proportional to the lever position; the fur-
ther the lever is advanced forward, the faster the
tractor moves. It is not necessary to hold the FSC
in position since the friction lock maintains the se-
lected lever position. Pulling back on the steering
levers overrides the FSC setting and slows or stops
forward 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.
Front Body Latch Release
The front portion of the tractor body hinges forward
for maintenance access and is latched down in the
OPERATING position. To raise the body, move the
latch release backward.
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 rst 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.
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 has two positions. Pushing the lever DOWN
engages the PTO that drives the mower blades.
Pulling the lever UP disengages the PTO and en-
gages the blade brake.
NOTE: On GHS equipped models, the Powerl
®
motor and Grass-Pak
®
full signal switch are acti-
vated by engaging the blade clutch. Refer to Using
the GHS Catcher in this section for a complete de-
scription of GHS operation.
