replace it before operating the mower.
5. Always wear safety glasses and safety shoes
when operating or maintaining this mower. Do
not wear loose-fitting clothing.
6. Disconnect the spark plug wires and remove
the key from the ignition to prevent the engine
from accidentally starting before performing
any maintenance on this mower.
7. Never run the engine indoors without adequate ventilation. Exhaust fumes are deadly.
8. To avoid serious burns, do not touch the
engine, exhaust pipe or muffler while the
engine is running or until it has cooled after it
has been shut off.
9. The liquid in the battery is dilute sulfuric acid.
Always wear safety glasses and rubber gloves
when working on the battery. Do not overfill
the battery.
10. Lead-acid batteries generate hydrogen and
oxygen gases which form an explosive mix
-
4
ture. Keep sparks and flames away at all
times.
11. When looking for oil leaks, never run your
hand over hydraulic hoses, lines or fittings.
Never tighten or adjust hydraulic hoses, lines
or fittings while the system is under pressure.
If high-pressure oil penetrates the skin, the oil
must be removed within a few hours by a doc
tor familiar with this form of injury or serious
complications may result.
B. Related to Fuel
1. Fuel is highly flammable and its vapors can
explode if ignited. Please respect it.
2. Do not smoke or permit others to smoke
while handling fuel.
3. Always use approved containers for fuel and
fill slowly to decrease the chance of static
electricity buildup and spillage.
4. Store fuel in well ventilated and unoccupied
buildings away from sparks and flames.
5. When dispensing gasoline into approved containers, place the container on the ground
when refueling to avoid a possible static elec
tricity ignition of fuel vapors.
6. Do not fill containers while it is inside a vehicle, trunk, the bed of a pickup or floor of a
trailer.
7. Always shut off the engine and permit it to
cool before removing the fuel tank cap.
8. Always fill the fuel tank outdoors.
9. If the fuel container spout will not fit inside the
fuel tank opening, use a funnel.
10. When filling the fuel tank, stop when the fuel
reaches one inch from the top. This space is
necessary for tank expansion.
11. Wipe up any spilled fuel.
Do not overfill
.
C. Related to Batteries
Batteries are stored electrical energy devices that
may be serviceable with removable caps (the electro
lyte levels can be checked), or may be non-serviceable (no attempt should be made to open the vents).
Batteries may contain lead (Pb) and sulfuric acid,
and they must be re-cycled and not disposed of nor
abandoned. Sulfuric acid can cause severe burns,
and in the event of contact, the areas should be
flushed with water and a physician contacted. Bat
tery cases should not be punctured. Lead is poisonous and is contained within the positive and negative
terminals as well as within the battery’s internal gridwork of plates and active materials.
Explosive gases are generated when batteries are
re-charged, so sparks, flames and heat sources
should be avoided. Loose connections at the battery
-
terminals can produce sparks and heat...connections
to the terminals must be kept tight, and the terminals
and battery surfaces kept clean of acids and corro
sion. If batteries are re-charged or “jumped” from
external sources, make sure that the connections are
made properly and in the correct sequence...connect
to the positive terminal of the good battery first, then
connect that to the positive terminal of the weak bat
tery. The third connection should be to the negative
terminal of the good battery, followed by the negative
terminal of the weak battery. If sparks are observed
or heating of the wiring or connectors is detected,
disconnect in reverse order (I.E., the negative termi
nal of the weak battery first). Batteries should be recharged at a constant voltage...generally 14.5 +/- 0.5
volts DC for a nominal 12 volt DC battery.
D. When Mowing
1. Keep adults, children and pets away from the
area to be mowed.
2. When operating this mower in the forward
direction, DO NOT allow the steering levers to
return to the neutral position on their own.
-
-
Always maintain a firm grip on the levers,
operate them smoothly and avoid any sudden
movements of the levers when starting or
stopping.
3. If the mower is equipped for side discharge,
never use the mower without the discharge
chute installed and placed in the down position.
4. Always remove debris and other objects from
the area to be mowed.(
grass will reduce traction.)
5. Mow only in daylight.
6. Watch for holes, sprinkler heads and other
hidden hazards.
7. Avoid driving too close to trees, creeks,
ditches, sand traps and other obstacles.
8. Before backing up, check behind you and
watch where you’re going.
9. Always reduce speed when making a turn,
and when grass is wet.
10. Always mow across slopes, never up and
down the slope. Do not operate on steep
slopes and slow down before turning.
11. 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.
12. If you hit a solid object while mowing, turn off
the blade clutch switch, place the left and right
steering levers in the neutral position, move
the throttle to slow, set the parking brake, shut
off the engine and take the key from the igni
tion switch. Inspect for damage. Repair any

damage. Make sure the blades are in good
condition and that the blade bolts are tight
before restarting the engine.
13. Never leave the mower unattended without:
turning off the blade clutch switch; placing the
left and right steering levers in the neutral
position; moving the throttle to slow; setting
the parking brake; shutting off the engine and
taking the key from the ignition switch.
14. Never walk or stand on the discharge side of a
mower with the engine running. Turn off the
blade clutch switch if another person
approaches while you are operating the
mower.
15. Never attempt to operate the traction unit
without the mowing deck attached.
16. 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 to permit proper cooling.
E. Towing
1. Tow only with a machine that has an approved
hitch designed for towing. Do not attach towed
equipment except at the hitch point.
2. Follow the manufacturers recommendation for
weight limits for towed equipment and towing
on slopes.
3. Never allow children or others in or on towed
equipment.
4. On slopes, the weight of the towed equipment
may cause loss of traction and loss of control.
Note:
5. Travel slowly and allow extra distance to stop.
5 degrees (9%) maximum slope.
DANGER:
Damaged ROPS and OPDs must be replaced prior
to operator use!
3. Seat belts shall be used and shall be properly fastened about the operator’s waist at all
times, except when the ROPS or OPDs are:
- not properly installed and/or not properly
secured onto the machine
- damaged in such manner that their structural integrity has been compromised
- not in their fully upright and locked position
4. Seat belts are attached to the movable portion of the seat when suspension seats are
utilized, and therefore the seat-mounting
base must be secured to its pivot means and
the pivot means latched to the frame of the
machine. Seat belts are attached to the seat
or the frame of the machine when non-sus
pension (standard) seats are provided, however, if a suspension kit is added to a seat,
the seat belt must be attached to the mov
able portion of the seat or suspension mechanism, the seat-mounting base must be
secured to its pivot means, and the pivot
means be latched to the frame of the
machine.
-
-
DANGER:
If ROPS and OPDs are folded down or missing,
seat belts shall not be fastened. Worn or damaged
seat belt assemblies must be replaced prior to
operator use.
F. Operator Protection System -Foldable
1.
This machine is equipped with an
Protective System (OPS), which includes:
a. A Roll Over Protective Structure (ROPS) or
Operator Protective Device (OPD) which
may be of the fixed or folding configuration
b. Seat belt assembly with retractable function
2. ROPS and OPDs are structures designed to
provide a crush-resistant space for the oper
ator when properly seat-belted within the
designated seating area of the machine in
the event of a machine tip-over or roll-over.
Folding ROPS and OPDs shall be used in
their fully upright and locked configurations
except in those circumstances whereby they
need to be momentarily folded-down to avoid
contact with items such as tree limbs, clothes
lines, guy wires, buildings, etc. At other times
and conditions, ROPS and OPDs shall be in
their fully upright and locked configurations.
Operator
5. Brush Guards and canopies can afford additional protection for the operator. The Brush
Guard can deflect tree limbs, clothes lines,
and other obstacles that otherwise could
come in contact with the ROPS and OPDs.
Contact of ROPS and OPDs by items such
as tree limbs, clothes lines, guy wires, and
buildings, could create hazardous conditions
-
6
whereby the machine could experience a tipover or roll-over. The canopy can provide
protection for the operator from some envi
ronmental exposure (sunlight, rain, etc.).
Work lights may be available.
6. The ROPS and seat belt are integral parts of
this machine and should not be tampered
with, modified in any manner, or removed.
7. The ROPS extends above and behind the
operator position, and therefore the operator
must be aware of potential contact of the
ROPS with items such as trees, buildings,
doorways, clothes lines, utility wires, etc., that
could cause the machine to upset or roll
-
-
over....use caution in (or avoid) areas where
the ROPS could come in contact with any
structures, trees, etc.
8. The ROPS and seat belt add additional mass
that elevates the machine’s Center of Gravity
(C.G.) which negatively affects the machine’s
stability and traction....use extra caution when
operating on slopes.
9. Inspect the ROPS and seat belt assemblies
on a regular basis for damage and improper
operation....replace all components that are
damaged or are not functioning properly with
authorized replacement parts.
10. Failure to use the seatbelt properly could
result in serious injury or death if an acciden
tal overturn occurs. In order for the ROPS to
be effective, the seat belt must be securely
fastened around the operator at all times
when the operator is on the machine. Contact
with the ROPS during an overturn could
cause serious injury or death.
11. The ROPS will not prevent the machine from
upsets or roll overs.
12. Only approved attachments should be used
on this machine.
G. Suspension Seat
1. This unit is equipped with an adjustable suspension seat system, which includes a foldforward seat with retractable seat belt
assembly, a low profile mechanical suspen
sion, and an Operator Presence Sensor
(OPS).
2. The seat bottom is covered with a heavyduty vinyl fabric and integrates the EVC
cushion comfort system that provides up to 1
3/8” dampered (for shock isolation) suspen
sion travel. An OPS in the form of a switch, is
integrated into the seat bottom and is con
nected to the machine electrical system. The
seat back is also covered with a heavy-duty
vinyl fabric, it adjusts to recline up to 16
degrees, and it will fold forward for transport
or protection from the elements of weather
(lever actuated on operator’s left side). The
armrests are adjustable for operator comfort
(knob inside armrests actuated from the bot
tom). Roller bearing single-locking tracks
provide easy repositioning fore/aft up to 5”
(lever actuated on lower right).
3. A mechanical suspension mechanism incorporates weight/ride adjustment controls for
operators in the 125 to 275 lb. weight range
(turn the knob on the front of the seat clock
wise to increase the weight capacity and
counter-clockwise to decrease. Self-lubricat
ing bearings are utilized throughout the suspension mechanism that provides an
additional 2” of suspension travel.
4. A retractable seat belt assembly with inertialock is attached to the “ride” portion of the
seat frame. The seat frame is attached to the
mechanical suspension, which is attached to
the roller tracks that are bolted to the seat
base in one of the three (3) locations - the
seat assembly can be detached and reinstalled 1” forward or 1” aft from the factory
installed position. When the two (2) hairpin
clips are removed from the frame-mounted
stud-bolts, the complete seat assembly and
-
seat base can be pivoted forward onto the
foot platform - this provides access to the
battery, hydraulic reservoir and filter, as well
as some of the electrical system and control
linkages. The seat base must be secured
with the hairpin clips prior to machine opera
-
tion.
Note: The seat base must be secured by
properly installing the hairpin clips into both
frame-mounted stud-botls, otherwise, the seat
assembly could tilt forward. The Operator
Presence Sensor must be connected to the
electrical wiring harness.

A.General
1. When Mowing:
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 levers when starting 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. Watch for 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 turning 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 downhill side of the machine...I.E.,
maintain the uphill side lap bar “essen
tially” in a fixed position.
Parking Brake
k. Be careful when crossing gravel paths or
roadways. Always turn off the blade clutch
switch and wait until the blades stop rotat
ing 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 steer
ing levers in the neutral 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. Never leave the mower unattended without
observing the following: turn off the blade
clutch switch, placing the steering levers in
the neutral position, moving the throttle to
slow, setting the parking brake, shutting off
the engine and taking the key from the igni
-
tion switch.
n. Never walk or stand on the discharge side
of the mower when the engine is running.
Turn off the blade clutch switch if another
person approaches while you are operat
-
ing 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.
Note: If low traction conditions occur, follow
these procedures for “zero turns”:
To turn clockwise (front of machine moves toward RIGHT)
when traveling FORWARD:
1. Come to a stop,
2. Then slowly move both lap bars rearward (no more
than 1/2 maximum reverse speed) to initiate REVERSE
travel,
3. Then slowly move the LEFT lap bar forward while
maintaining the RIGHT lap bar in the rearward travel
position.
4. To stop the turn and reintiate FORWARD travel,
slowly move the RIGHT lap bar from the REVERSE
travel position to a FORWARD travel position equal t that
of the LEFT lap bar.
5. Alternatively, release both lap bars and the machine
should stop turning, (this is a safety check, the normal
procedure is for the operator to slowly bring the lap bars
to the Neutral psoition).
To turn counter-clockwise (front of machine moves toward
LEFT) when traveling FORWARD:
1. Come to a stop,
2. Then slowly move both lap bars rearward (no more
than 1/2 maximum reverse speed) to initiate REVERSE
travel,
3. Then slowly move the RIGHT lap bar forward while
maintaining the LEFT lap bar in the rearward travel posi-
tion.
4. To stop the turn and reintiate FORWARD travel,
slowly move the LEFT lap bar from the REVERSE travel
position to a FORWARD travel position equal t that of the
RIGHT lap bar.
5. Alternatively, release both lap bars and the machine
should stop turning, (this is a safety check, the normal
procedure is for the operator to slowly bring the lap bars
to the Neutral psoition).
2. Safety Awareness when Mowing
a. Do not operate on steep slopes, those above
15 degrees (27% slope).
b. Avoid 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
mower toward streets, buildings, playgrounds,
parking lots, other machines, animals, and
other people.
e. Avoid operation or use extreme care if the
traction surface is wet, unstable, or slippery.
f. Use extra care when grass clippings, leaves,
pine needles, or debris are present as traction
can be reduced.
g. Slow-down before turning and come to a com-
plete stop before any zero turn maneuver.
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 Pattern
a. Pick a point on the opposite side of the area to
be mowed (post, tree, shrub, etc.).
B.Controls
11
b. If on an hillside, start 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 fac
tors 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. Remember, a zero turn requires that the for-
ward 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.
1. Engine ignition and start switch: (See Figure
1.) Located on the instrument housing below the
right side of the operator’s seat. When the key
is inserted and turned clockwise, 45 degrees,
the ignition circuit is closed. When the engine is
“cold”, have the switch in the “on” position until
the glow-plug light goes out. Turning the switch
further against spring pressure starts the
engine. The engine will only start if the blade
clutch switch is in the “off” position, the parking
brake is engaged and the left and right steering
levers are in the neutral position. The key should
always be removed from the switch if the opera
tor leaves the mower’s seat.
2. Glow Plugs:
(See Figure 1) Combustion chamber plugs are fitted with the necessary precise tip
protrusion into each combustion chamber, to
enable the sprayed fuel to be properly ignited
during cranking, without causing a significant
drop of combustion efficiency during engine run
ning. Glow plugs, due to their high tip temperature when activated, give satisfactory starting at
ambient temperature-bottom limits approaching
that of other starting-fluid aids.

operator’s seat. Moving the throttle control from
