A.General
1. When Mo wi n g:
a. Keep adults, children, and pets away from
the area to be mowed.
b. When operating this mower, in the forward
direction, do not allow the steering levers
to return to Neutral on their own. Always
maintain a firm grip on the levers , operate
them smoothly and avoid any sudden
movements of the lev ers when s tarting and
stopping.
c. If the mower is equipped for side dis-
charge, never use the mower without the
discharge chute installed and placed in the
down position.
d. Always remove debris and other objects
from the area to be mowed (Note: debris
and loose grass will reduce traction).
e. Mow only in daylight.
f. Wat ch f or holes, sprinkler heads, and other
hidden hazards.
g. Avoid driving too close to trees, creeks,
ditches, sand traps, and other obstacles.
h. Before backing up, check behind and
watch where you are going.
i. Always reduce speed when making a turn,
and when grass is wet.
j. Always mow across slopes, never up and
down the slope. Do not operate on steep
slopes and slow down before turning.
Avoid tur ning downhill if possible, start at
the bottom and work up to the top. Use
extra care and go slowly when turning
downhill. Control the speed and direction
of the zero turn machine “primarily” with
the speed/directional control (lap bar) of
the down hill s id e o f the machine...I .E . ,
maintain the uphill side lap bar “essentially” in a fixed position.
k. Be careful when crossing gravel paths or
roadways. Always turn off the blade clutch
switch and wait until the blades stop rotating and raise the cutting deck to the transport position. Always allow other vehicles
to have the right of way.
l. If you hit a solid object while mowing, turn
off the blade clutch switch, place the steering levers in the neutral, opened-out position, move the throttle to slow, set the
parking brake, shut off the engine, and
take the key from the ignition switch.
Inspect for damage. Repair the damage.
Make sure the blades are in good condition
and that the blade bolts are tight before
restarting the engine.
m. Nev er leave t he mower unattended without
observing the following: turn off the blade
clutch switch, placing the steering levers i n
the neutral open-out position, moving the
throttle to slow, setting the parking brake,
shutting off the engine and taking the key
from the ignition switch.
n. Never walk or stand on the discharge side
of the mower when the engine is running.
Tur n off the blade clutch switch if another
person approaches while you are operating the mower.
o. Never attempt to operate the traction unit
without having the mowing deck attached.
p. Keep the mower and especially the engine
and hydraulic components clean and free
of grease, grass, and leaves to reduce the
chance of fire and permit proper cooling.
2. Safety Awareness when Mowing
a. Do not operate on steep slopes, those
above 15 degrees (27% slope).

b. Av oid turning downhill if possible, if not use
extra care and go slowly.
c. Avoid turning when going downhill, traction
is at a minimum going downhill.
d. Do not operate with discharge side of the
mowe r toward st reets, buildings, p l ay-
grounds, parking lots, other machines, ani-
mals, and other people.
e. Avoid operation or use extreme care if the
traction surface is wet, unstable, or slip-
pery.
f. Use extra care when grass clippings,
leaves, pine needles, or debris are present
as traction can be reduced.
g. Slow-down before turn ing and come to a
complete stop before any zero t urn maneu-
ver.
h. Do not stop machine or park machine over
combustible materials such as dry grass,
leaves, debris, etc.
3. To Mow Grass and Produce a Striped P attern
a. Pick a point on the opposite side of the
area to be mowed (post, tree, shrub, etc.).
b. If on an hillside, star t at the bottom so that
the turns are uphill rather than downhill.
c. Align the mower so as to head directly
toward the object on the far side.
d. Slowly increase the speed of the machine
to match cutting conditions, terrain, and
operator familiarity with the controls and
keep the machine headed directly toward
the alignment object. Do not go fast as to
reduce cut quality or to be uncomfortable
in controlling the speed and direction of the
machine.
e. When approaching the other end of a strip,
slow down or stop before turning. A U-turn
is recommended unless a zero turn is
required. The speed of a U-turn that will
allow for machine controllability and minimal turf defacement will be dependent on
several factors including: the speed of the
turn, the radius of the turn, the tire tread
pattern, the traction coefficient of the tire to
the traction surface, the slope of the traction surface.
f. Remem ber, a zero turn requires that the
forward or reverse travel of the machine be
stopped prior to the initiation of the turn or
severe turf defacement can occur.
g. To prevent rutting or grooving of the turf,
change the direction that the strips are
mowed by approximately 45 degrees the
next and each subsequent time that the
area is mowed.
B.Controls
1.
Engine Ignition and Start Switch:
(See Figure 1.) Located on the instrument housing
below the rig ht side of the operator’s seat.
When the key is inserted and turned clockwise, 45 deg ree s, the ign itio n ci rcuit is cl osed.
Turning the switch further against spring pressure starts the engine. The engine will only
start if the blade clut ch switch is in th e “off”
position, the parking brake is engaged and
the left and right steeri ng lever s are in the
neutral, opened-out position. The ke y sh ould
always be re m oved from the swit ch if the
operator l eaves the mower’s seat.
2.
Engine Throttle Control:
(See Figure 2.)
Located on th e left side of the mow er next to
the operat or’s seat. Moving the t hrot tle c ontro l
from the rear to the front will increase the
engine spee d fr om slow to fast.
3.
Left and Right Steering Levers:
(See Fi gure
3.) These hinged le ve rs ope n out to the sid e in
the neutral position to permit the operator to
be seated or to leave the mower’s seat. The
operator, when seated, can pull th e levers up
to the operating position, a comfortable forearm’s length away. These levers control all of
the movements of the mower. Pushing both
lev ers forward causes the mower to move forward. Pulling both lev ers bac k causes the
mower to move bac k ward. Pushing one lever
ahead of the ot her lever cau ses the traction
wheel on the side where the lever is ahe ad t o
rotate f aster than the other traction wheel,
making the mo we r tu rn tow ard t he side w here
the le ver is behind. When on e l ever is pushed
forward and the other l ever pulled back the
same amount, one traction wheel will turn in
reverse a nd the mower will turn within its own
length.
In order to start the engine, both steering
lev ers must be opened out to the side in the
neutral position; the parking brake must be
engaged; and the blad e clu tch s w itch m us t be
“off”. However, once the engine starts, the
parking bra k e must be release d before the
operator pl aces the steering levers into the
operating position or the engine will
automatically shut off.
Note:
The Steering Le ver will return tow ard
neutral when released, but they should be
placed in neutral b y the driver. If the Drive
Handles are not placed in neutral, the tractor
may creep.
