and battery surfaces kept clean of acids and corrosion. 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 battery. 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 terminal 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.
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 doctor 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 electricity 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. Do not overfill.
11. Wipe up any spilled fuel.
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.(Note: debris and loose
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 ignition switch. Inspect for damage. Repair any
damage. Make sure the blades are in good
C. Related to Batteries
Batteries are stored electrical energy devices that
may be serviceable with removable caps (the electrolyte 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. Battery 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 sprks and heat...connections
to the terminals must be kept tight, and the terminals

condition and that the blade bolts are tight
before restarting the engine.
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.
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.
Never attempt to operate the traction unit
without the mowing deck attached.
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.
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-suspension (standard) seats are provided, however, if a suspension kit is added to a seat,
the seat belt must be attached to the movable 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.
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 degrees (9%) maximum slope.
5. Travel slowly and allow extra distance to stop.
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
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
whereby the machine could experience a tipover or roll-over. The canopy can provide
protection for the operator from some environmental 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
This machine is equipped with an Operator
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 operator 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.

counter-clockwise to decrease. Self-lubricating 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 operation.
could cause the machine to upset or rollover....use caution in (or avoid) areas where
the ROPS could come in contact with any
structures, trees, etc.
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.
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.
Failure to use the seatbelt properly could
result in serious injury or death if an accidental 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.
The ROPS will not prevent the machine from
upsets or roll overs.
Only approved attachments should be used
on this machine.
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.
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 suspension, 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) suspension travel. An OPS in the form of a switch, is
integrated into the seat bottom and is connected 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 bottom). 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

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 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 ignition 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 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
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 discharge, 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.,
10
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 position.
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 complete 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.).
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 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. Remember, 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
right side of the operator’s seat. When the key is
inserted and turned clockwise, 45 degrees, the
ignition circuit is closed. 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 operator leaves
the mower’s seat.
2. Engine Throttle Control: (See Figure 1.)
Located on the left side of the mower next to the
operator’s seat. Moving the throttle control from
the rear to the front will increase the engine
speed from slow to fast.
3. Left and Right Steering Levers: (See Figure 3.)
These hinged levers open out to the side in any
position to permit the operator to be seated or to
leave the mower’s seat. The operator, when
seated, can pull the levers up to the operating
position, a comfortable forearm’s length away.
These levers control all of the movements of the
mower. Pushing both levers forward causes the
mower to move forward. Pulling both levers back
causes the mower to move backward. Pushing
one lever ahead of the other lever causes the
traction wheel on the side where the lever is
ahead to rotate faster than the other traction
Steering Levers
Note: The 19hp
and 23hp use the 5
gallon fuel tank.

wheel, making the mower turn toward the side
where the lever is behind. When one lever is
pushed forward and the other lever pulled back
the same amount, one traction wheel will turn in
reverse and the mower will turn within its own
length.
In order to start the engine, both steering levers
must be in the neutral position; the parking brake
must be engaged; and the blade clutch switch
must be “off”. However, once the engine starts,
the parking brake must be released before the
operator places the steering levers into the
operating position or the engine will
automatically shut off.
Note: The Steering Lever will return toward
neutral when released, but they should be placed
in neutral by the driver. If the Drive Handles are
not placed in neutral, the tractor may creep.
4.
5.
6.
Electric Blade Clutch Switch: (See Figure 1.)
Located on the right side of the mower beside the
ignition switch. This is an “on/off” push pull switch
that controls the electric blade clutch which supplies power to the cutting blades through the
PTO. The switch must be turned off to start the
engine and should be turned off for safety any
time another person approaches the mower or
the mowing deck is raised to the transport position. Power to the electric clutch will also be cut
off if the operator leaves the operator’s seat.
Parking Brake: (See Figure 2.) Located on the
left side of the traction unit. The handle is an
overcenter lever which applies the drum-type
brake on each drive wheel when the handle is
pulled to the rear. The brake must be engaged in
order to start the engine.
Foot Pedal Lift: (See Figure 3.) Located on the
right front corner of the mowing deck. A two pedal
mechanism is provided whereby one pedal (first)
is used to raise, to momentarily hold the implement at a desired height (if needed), and to latch
it in the transport or maximum height setting. A
second pedal is used to unlatch the mechanism
from the transport or maximum height setting, to
12
Fuel Shutoff Valve
lower, or to momentarily hold the implement at a
desired height. The pedals can also be used in
conjunction with each other when the upper portion of a foot activates the first pedal to raise the
implement, and the lower portion of the foot
(heel) activates the second pedal to release the
latch. This provides a hands-free operation with
the exception of when an implement height
change is required. For changing implement
height, at least one hand is required to reposition
the pins to provide 1/4” height-of-cut increments.
The mechanism includes: An adjustable location
foot pedal that is used to raise the implement
and/or latch it in the transport position, that is
directly connected to the implement lift linkage;
adjustable force counter-balance springs to
reduce the effective weight of the implement and
thereby reducing the forces needed on the first
and second pedals for activation - tighten both
springs equally to reduce the force at the foot
pedal; a second pedal pivotally attached to the
first pedal that releases the mechanism from the
latched configuration; a height adjustment link
and index provide predetermined height for the
implement - it is settable in 1/4” increments; a
lock position for the height adjustment link settable by the pin in the highest (also transport position) or lowest (also for mower deck removal and
installation).
The following features are incorporated into the
foot pedal implement lift design: Foot actuated
implement lift with one pedal (1st) for lift and
latch, with a second pedal for release and lower;
allows for some operators with physical limitations to use the implement lift mechanisms and
the machine; reduces potential for operator
fatigue; accommodates a variety of operator
sizes, shapes, and strengths; does not require
the use of hands (with the exception of resetting
the implement height) during normal machine
operation - thusly the hands can be used for other
functions
7. Fuel Shutoff Valve: (See Figure 4.) Located on
top of the fuel tank(s). When turned in a clockwise
beneath the operator’s seat. Always wipe
off the area around the oil tank fill neck
before checking the oil level to prevent dirt
from contaminating the oil. Remove the cap
and make sure the oil level is a 1/4” below
the oil tank fill neck. If the oil level is low, fill
with Shell Rimula 15W40 or equivalent oil.
Equivalent oil should meet GM Allison C-4.
d. Tires: 8-10 psi Rear, 20-25 psi Front Caster
Tires
direction until it stops, it will shut off the flow of
fuel to the engine. When turned in a counterclockwise direction it will open and allow fuel to
flow to the engine. Close this valve if you are not
going to run the mower for a period of 30 minutes or more to prevent flooding the engine.
8. Seat Adjustment Lever: The Seat Adjustment
Lever is located beneath the seat. The Seat
Adjustment Lever is used to move the seat forward and backward. To place the seat in the
desired position pull the seat adjustment lever to
the left then push the seat forward or back to the
desired position. Release the lever so the seat
will lock in place.
9. Digital Tachometer and Hour Meter: (See Figure 1) Located on the right side of the mower in
front of the ignition switch. When the machine is
running the tachometer displays engine rpm.
When the machine is off the tachometer displays running time.
10.Choke Lever: (See Figure 1) The Choke Lever
is located on the left instrument panel next to the
seat. The Choke Lever is operated manually.
Having the Choke Lever in the ON position helps
the engine to start during initial start-up. During
normal operation the Choke Lever should be in
the OFF position.
Note: New tires are overinflated in order to
properly seat the bead to the rim. The normal
working pressure for the traction tires is 8-10
psi. The front caster wheels should be inflated
to 20-25 psi.
2.
Check that all Nuts, Bolts and Screws are
Tight.
3. Check the tension of the deck drive belts.
a. Remove the deck cover
b. The tension of the deck drive belts are
maintained by a spring mechanism that
adjusts for wear and stretch.
c. Examine the belts for cuts, fraying, and
excessive wear. Replace if any of these are
detected.
d. Replace the deck cover.
4. Adjust the Mowing Deck: The cutting height
is set anywhere in the range of 1-1/2" to 5".
You may need to adjust the mowing deck to
achieve the proper angle for mowing. Follow
the procedures below to set the appropriate
angle to the mowing deck.
a. Park the mower on a flat paved surface,
engage the parking brake, shut off the
engine, remove the key from the ignition
switch, remove connection of the spark
plugs and using the second foot pedal,
lower the mowing deck into the cutting position.
b. Using a ruler, pencil and paper, measure
and note the distance from the paved surface to the bottom edge of the mowing
blade at the front and the back of the deck
on each side of the mower. (Four dimensions.)
Note: The Tanks equipped with E.F.I. do not
have a choke control.
Note: There will be a flashing “LUBE” for
each recommended lubrication interval. There
is a flashing “OIL” at each recommended
engine oil and filter change.
C.Initial Adjustments
1.
Check the fluid levels and tires:
Note: These checks should be made daily,
before starting the engine.
a. Fuel: Using a good grade of unleaded, regular gasoline (for a gasoline engine), fill the
fuel tank (beside the engine on the left or
right side of the mower). When the fuel
reaches one inch from the top of the tank,
stop. DO NOT OVERFILL. Space must be
left for expansion.
b. Engine Oil: (Filled at the factory before
shipment.) Pull out the oil dipstick, wipe it
off and reinsert it. Pull it out again and read
the oil level. If it is below the operating
range, add oil through the fill tube using a
funnel to bring it up to the top of the operating range.
Note: The front edge of the mowing deck
should be 1/8"-1/4" below the rear edge of the
deck so that the blades are cutting grass in
only the front half of their circular path. This
decreases friction and reduces the drive power
required.
c.
Note: Gasoline Engine: Use SAE 10W30 or
SAE 10W40 engine oil, rated for service SJ.
Shell Rimula 15W40 is also recommended and
provides service SL and CI-4 plus.
c. Hydraulic Oil: (Filled at the factory before
shipment.) The hydraulic oil tank is located
13
If the dimension at the front of the mowing
deck is 1/8"-1/4" lower than the dimension
at the rear of the deck on each side of the
mower, do not adjust. If not, you will need to
adjust the Deck Lift Spring Assist (See Fig-
fore-and-aft, as well as up-and-down —
9/16" wrench required).
c. Become familiar with all of the machine
controls, instrumentation, safety and
instruction signs, and safety devices.
d. Move (or have moved) the machine to a
safe, level area with no obstructions including objects, pedestrians, and animals.
2. Initial Operation:
a. Use protective equipment for eyes, hands,
hearing, feet, legs, head and other areas of
the body if needed — safety eye glasses,
gloves, earplugs, boots, hats, etc.
ure 5). You may also need to adjust the
Deck Links (See Figure 5).
Deck Lift Spring inner nut

WARNING:
Deck Links
Hearing Protection is required for all operator
exposure exceeding two (2) hours.
d. Lower the mower deck to the cutting position. With a wrench loosen the inner rear
nut on the Deck Lift Spring Assist. To
adjust the deck up or down, use a wrench
and with a few turns, adjust clockwise or
counter clockwise the outer rear nut of the
Deck Lift Spring Assist. Repeat this procedure on the opposite side of the Mower.
Once the deck is adjusted, retighten bolts.
e. With the deck still in the cutting position,
adjust the Deck Links. With a wrench
loosen the top inner bolt of the Deck Link.
To adjust the side of the deck up or down
turn the top bolt clockwise or counter
clockwise a few turns. Adjust both front
and rear Deck links as necessary.
Retighten nuts.
f. Raise the mowing deck to the transport
position using the upper foot pedal.
g. Use the second foot pedal to lower the
mowing deck to the cutting position and
repeat step “b.” above to make sure that
the desired cutting height has been
attained. If the dimensions are not correct,
repeat steps “c.” through “f.” above.
b.
Ensure that the area is free of animals and
bystanders, especially children!
c. Survey the area where the equipment is to
be used to make sure it is free of debris,
sticks, stones, wires, bones, and other foreign objects which could cause injury to
bystanders, damage to the machine, or
damage to nearby facilities.
d. Inspect the machine to make sure:
1. All guards, shields (including mower
chute deflector) are in their proper place,
are secure, and are functional.
2. That there are no spilled or leaking fuel
or oil sources, nor loose fuel or hydraulic
tank caps, hoses or fittings.
3. That there are no loose or missing hardware nor any missing items.
4. That no non-approved devices are
installed.
5. That all safety signs and decals are
properly installed and legible.
e. This is a one person machine, operator
only! Riders are not permitted under any
circumstance!
f. To start the engine on the machine:
1. Make sure the park brake is set to the
“ON” position, both lap bars are in the
neutral/start position, and the Power
Take Off (PTO also referred to as blade
control switch) is in the “off” (down) position.
2. Move the choke control forward and the
engine speed control (throttle) forward
(half way).
5. Lubricate all fittings listed in the maintenance section.
D. Zero Turn Break-In And Operating
Procedures
DANGER:
Reread the “When Mowing” Safety Precautions.
The following procedures are suggested for operators of ride-on machines which have zero turn
capabilities.
Note: E.F.I. Tanks do not have a choke control.
1. Orientation:
a. Read the entire Operator’s Manual.
b. Sit on the machine, adjust the seat beforeand-after, then adjust the speed/directional
(lap bar) controls (they can be adjusted
3. Insert the ignition key, turn the switch
toward the spring-loaded “Start” position,
maintain the Start position until the
engine begins to run, then release the
14
rotate and a “pivot turn” will be executed
— turf defacement could occur (if on
grass) as well as potential damages to
the traction surface and the tire. If the lap
bar on the turn side is not brought all the
way to neutral, then the turn side tire will
continue to rotate and a “U-turn” will be
executed with a low potential for turf
defacement as well as traction surface
and tire damage.
i. To drive in the REVERSE direction:
1. Make sure no bystanders, animals, or
objects are behind the machine. Look
behind the machine, and use extreme
care.
2. Slowly, move both lap bars toward the
rear of the machine until the machine
begins to move rearward. Release the
lap bars and the machine should stop.
The more the lap bars are moved toward
the rear of the machine, the faster the
machine will move in the reverse direction. Release the lap bars and the
machine should stop traveling in reverse
(this is a safety check, the normal procedure is for the operator to slowly bring
the lap bars to the neutral position).
3. Do not retard the lap bars rapidly as this
could cause turf defacement and/or loss
of traction.
4. To turn, retard one lap bar ahead of the
other and the machine will turn toward
the same side that was retarded — I.E.,
to turn counter-clockwise (to the LEFT),
move the LEFT lap bar rearward more
than the right side, and to turn clockwise
(to the RIGHT), move the RIGHT lap bar
rearward more than the left side. NOTE:
If one lap bar is in the neutral position
and the other is retarded, the turn side
tire will not rotate and a “pivot turn” will
be executed. Turf defacement could
occur (if on grass) as well as potential
damages to the traction surface and the
tire. If the lap bar on the turn side is not
brought all the way to neutral, then the
turn side tire will continue to rotate and a
“U-turn” will be executed with a low
potential for turf defacement as well as
traction surface and tire damage.
j. To perform a “zero turn”:
1. Please note, a zero turn maneuver can
not be executed while the machine is
moving in the Forward or, Reverse directions, the machine must come to a stop
first.
2. To turn clockwise, slowly move the LEFT
lap bar forward while simultaneously
moving the RIGHT lap bar rearward.
switch (it will return to the “Run” position).
4. Retard the choke slowly by moving it
rearward. If the engine is “cold”, the
choke may need to be partially applied
for a few minutes. Be sure to totally
retard the choke after the engine has
“warmed up”.
g. Check safety devices:
1. With the park brake engaged, try to
move one of the lap bars (speed/directional control) from the neutral/start position — the lap bars should not move with
the park brake engaged.
2. Repeat this procedure with the opposite
side lap bars.
3. With the park brake engaged and the lap
bars in the neutral/start position,
advance the engine speed control completely forward (Hi-idle), engage the PTO
control switch (pull upward), then lift off
the seat — the engine should stop running. Sit down and the engine should
run. Turn off the PTO by pushing the
control switch down.
h. To drive in the FORWARD direction:
1. Set the engine speed to 2000 to 2500
rpm (refer to tachometer on right control
panel). This must be increased to full
speed (3525-3675 rpm) after becoming
familiar with the machine.
2. Release the park brake.
3. Slowly, move both lap bars toward the
front of the machine until the machine
begins to move forward — release the
lap bars and the machine should stop
moving. The more that the lap bars are
moved toward the front of the machine,
the faster the machine will move in the
forward direction. Release the lap bars
and the machine should stop traveling
forward. (This is a safety check, the normal procedure is for the operator to
slowly bring the lap bars to the neutral
position).
4. Do not advance the lap bars rapidly as
this could cause turf defacement, loss of
traction, and/or instability.
5. To turn, advance one lap bar ahead of
the other and the machine will turn
toward the opposite from the side that
was advanced — I.E. to turn clockwise
(to the Right), move the LEFT lap bar forward more than the right side, and to
turn counter-clockwise (to the LEFT),
move the RIGHT lap bar forward more
than the left side. NOTE: If one lap bar is
in the neutral position and the other is
advanced, the turn side tire will not
15
Release both lap bars and the machine
should stop turning.
3. To turn counter-clockwise, slowly move
the RIGHT lap bar forward while simultaneously moving the LEFT lap bar rearward. 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 position).
3. Start the Engine:
a. Open the fuel shutoff valve.
b. Sit on the Seat. Set the parking brake
“On”.
c. Make sure that the left and right steering
levers are in their neutral position.
d. Turn the electric blade clutch switch “Off”.
e. Push the throttle control to a position a
third of the way between slow and fast.
f. Insert the key in the ignition and start
switch and turn the switch to “On”.
g. Gasoline Engine: If the engine is cold,
push the choke to the on position.
WARNING:
When operating this mower forward, do not
allow the steering levers to return to the neutral position on their own. Always maintain a
firm grip on the steering levers, operate them
smoothly and avoid any sudden movements of
the levers when starting or stopping.
g. To go forward, move both steering levers
slightly forward and the mower will slowly
move forward. The farther you move the
levers forward the faster the mower will go
forward.
h. To back up, move both steering levers
slightly backward and the mower will
slowly move backward. The farther you
move the levers backward the faster the
mower will go backward.
i. To turn, pull the lever back on the side to
which you want to turn. The farther back
you pull the lever, the faster and more
sharply you will turn. Initially, you will have
to be careful to avoid turning to fast and
too far.
j. After you have mastered operating the
mower, use the second foot pedal to lower
the mowing deck to the cutting position
and pull on the electric blade clutch switch
to start the blades rotating.
k. Practice mowing in straight passes. When
you feel confident, slowly practice mowing
around obstacles such as trees.
Note: E.F.I. Tanks do not have a choke control.
h. Turn the ignition key in a clockwise direction to the “Start” position until the engine
starts.
Note: Do not hold the key in the “Start”
position for more than 10 seconds or you may
damage the starter. If the engine does not start
in this time, wait about 30 seconds and try
again.
i.
5.
Gasoline Engine: Once the engine starts,
push the choke on halfway and as the
engine warms, push the choke off all the
way.
4. Operating the Mower: Operating a zero-turning-radius mower is not like operating a tractor-type riding mower. The zero-turning-radius
mower is much more maneuverable and
much less fatiguing to operate. However, getting used to the fingertip control of the zeroturning-radius mower takes some practice.
We strongly recommend that you locate a
“test area” where you can operate the mower
for about 30 minutes without being disturbed.
a. Get into the operator’s seat.
b. Start the engine.
c. Use the upper foot pedal to raise the mowing deck to the transport position. Make
sure the blade clutch switch is off.
d. After the engine has warmed, adjust the
throttle to the fast position.
e. Release the parking brake.
f. Fold in the steering levers to the operating
position.
Parking the Mower:
a. Push off the electric blade clutch switch.
b. Use the upper foot pedal to raise the mowing deck to the transport position.
c. Drive the mower to the cleanup or storage
area.
d. Move the throttle to slow.
e. Place the steering levers in the neutral
position.
f. Set the parking brake.
g. Turn off the ignition switch and take the key
from the switch.
h. Close the fuel shutoff valves.
E.Mower Cutting Blades
The blades normally “factory installed” on a mower
afford the best grass cutting performance on the
majority of grasses and mowing conditions; however,
there will be occasions whereby the grass type,
stage of grass growth, soil conditions, and weather
conditions will require different cutting blade types.
Since the mower decks are designed so that over-lap
of the cutting blades generally exceed 1.5”, there is
no need for orientation of one cutting blade to an
16

SERVICE
adjacent blade (I.E., the blades do not need to be
“timed” nor synchronized).
Hi-lift- These are generally the best cutting blades
for most grasses and mowing conditions. These
blades will provide extra “lift” for the thinner leaf
grasses, will handle lush grasses, and will provide
maximum grass and debris discharge. These blades
are generally required for material collection systems. More horsepower is required for these blades
when compared to others, and they generally produce the highest noise levels.
WARNING:
Disconnect the spark plug wires or remove the
key from the ignition to prevent the engine
from accidentally starting before performing
any maintenance on this mower.
A. Mower Deck
Medium-lift- These blades require less horsepower
than the hi-lift, and they generally work well in wider
leaf grasses and some mulch applications.
1. Removing the Mower Deck:
a. Apply the parking brake. Remove ignition
key and both spark plug caps.
b. Lower the cutter deck to the ground. Capture the foot pedal by placing the height of
cut clevis pin in the “lock” position.
c. Remove tension of the PTO belt by moving
the belt tensioning rod.
Low-lift- These blades require less horsepower than
hi-lift and medium-lift blades, and they generally work
best with wide leaf grasses, sparse grass growth,
and sandy soil conditions. They generally produce
the lowest noise levels. Bahia blades are configured
without offset, and with a maximum amount of sharpened cutting edge.
Note: There is a certain amount of spring
tension due to the weight of the deck. When
removing the lift linkage from the deck the tension of the springs will go from the deck to the
foot pedal. Not capturing the foot pedal while
removing the lift linkage from the deck will
cause it to snap back.
Mulch- These blades are generally designed for use
in cutting decks equipped with mulch baffles. The
shape of the blade generally produces higher turbulence in order that the grass can be repeatedly cut
and re-cut into smaller pieces. These blades generally require more horsepower than other blades.
Mulch blades work best when the grasses are cut at
the highest levels, minimal lengths of grasses are
removed, and grass conditions are generally dry.

1.
Battery: The battery is located beneath the
operator’s seat. Remove the fillcaps and
check the level of the liquid electrolyte in the
battery every 50 operating hours. If the level
in any of the six cells has dropped below the
bottom of the split ring inside the fill hole, refill
the cell with distilled water. To keep the outside of the battery clean, brush on a strong
solution of bicarbonate of soda and water and
rinse with clean water. Keep the contacts and
cable ends clean with a wire brush and make
sure the connections are tight. Coat the terminals with petroleum jelly to prevent corrosion.
2. Battery Storage: When storing the Mower for
long periods of time the following guidelines
should be taken.
a. Disconnect the battery cables from the terminals and remove the battery. You will
have to remove the control panel to access
the battery strap. Replace control panel.
b. Clean the battery before storing. A dirty
battery will lose its charge over time.

6. Fuses: There is one fuse located in the wiring
between the ignition and start switch and
other electrical components. This is a standard plug-in type automotive fuse rated at 7.5
amp.
7. Safety Switches: There are three safety
switches in the electrical circuit which control
the engine. They are (1) the blade clutch
switch, (2) the steering lever/parking brake
switch, and (3) the seat switch.They operate
so that in order to start the engine, the blade
clutch switch must be off, the parking brake
must be engaged, and both steering levers
must be in the neutral position. Once the
engine is started, the seat must be occupied
and the parking brake must be released
before either of the steering levers can be
moved. Also, the seat must be occupied
before the blade clutch switch can cause the
blades to rotate.
8. Safety Switch Operation Checks: The following operational checks should be made
daily.
a. Blade Clutch Switch: Sit in the operator’s
seat. With both steering levers in the neutral position and the parking brake
engaged, turn the blade clutch switch “on”
and try to start the engine. The engine
should not start. If it does, the blade clutch
switch must be replaced. If the engine
does not start, turn the blade clutch switch
“off” and start the engine. Now turn the
blade clutch switch “on” and the blades
should rotate. If the blades do not turn, the
blade clutch switch must be replaced, the
seat switch must be replaced or the electric PTO clutch must be repaired.
d. Recharge battery when ever the specific
gravity value is less than 1.225
3. Battery Removal
Warning:
When removing the cables from the battery
follow these steps to avoid a short between
the wrench and the frame.
a. Remove the Negative (black) cable.
b. Remove the Positive (red) cable.
c. Release the hold down straps.
d. Remove the battery without tipping.
4. Installing the Battery
Note: The battery is delivered from the factory fully charged and filled with electrolyte.
a. Attach the Positive (red) cable.
b. Attach the Negative (black) cable.
c. Attach the rubber battery strap.
5. Jump Starting
Warning:
Note: For E.F.I. Tanks, the battery must be
The air-gap should be checked every 100
hrs. (or less, if severe operating conditions
exist such as when there are many on/off
cycles, mulching operations, material collection systems used, and dusty/dirty conditions), and the air-gap adjusted if more
than 0.025". To inspect, remove the “negative” cable from the battery and all sparkplug wires. The air-gap should be checked
with feeler gages in the three slots of the
BBC (PTO Clutch). See page 22 for air gap
adjustment specs. There are three inspection slots in the brake cover. To adjust, successively tighten each of the three gap
adjustment nuts an equal amount. Insert a
feeler gage (see page 22 for specs) into
each slot as the air gap adjustment nut are
tightened. The correct adjustment occurs
disconnected (Negative lead) for storage
exceeding four weeks. Do not “Jump Start” an
E.F.I. unit, recharge or replace battery to avoid
damage to the Electronic Control Unit (ECU).
Failure to use this starting procedure can
cause sparking, and the gases in the battery
to explode.
a. Attach the end of the red jumper cable to
the Positive terminal (+) of the charged
battery.
b. Attach the other end of the red jumper
cable to the Positive terminal (+) of the low
charge battery.
c. Attach the end of the black jumper cable to

when slight contact with the feeler gage
occurs. Engage the BBC (PTO Clutch) a
couple of times, and re-check the air-gap.
If it is not between the specs listed on page
22, repeat the adjustment procedure.
b. Steering lever/Parking Brake Switch: Sit
in the operator’s seat. With both steering
levers in the neutral position and the blade
clutch switch “off”, release the parking
brake and try to start the engine. The
engine should not start. If it does, the parking brake switch must be repositioned or
perhaps replaced. If the engine does not
start, engage the parking brake and start
the engine.
c. Seat Switch: With both steering levers in
the neutral position, the parking brake
engaged and the blade clutch switch in the
“off” position, start the engine. Now
release the parking brake, hold down on
the back of the operator’s seat against
spring pressure. Release the operator’s
seat and the engine should stop. If the
engine does not stop, the seat switch must
be replaced. With both steering levers in
the neutral position, the parking brake
engaged and the blade clutch switch in the
“off” position, sit in the operator’s seat and
start the engine. Turn the blade clutch
switch to the “on” position and the blades
should start to rotate. Raise up slightly off
the operator’s seat and the blades should
stop. If the blades do not stop when you
dismount from the operator’s seat, the seat
switch must be replaced.
d. Electric PTO Clutch: This clutch operates
when the engine is running, the operator is
in the operator’s seat and the blade clutch
switch is turned on.This electric clutch is a
fairly trouble free device. If a problem
develops and the blades do not turn, first
check the 20 amp fuse in the yellow, 16gauge wire between terminal “L” (for the
Gasoline Engine) on the ignition switch
and the hour meter and then investigate
the wiring harness and the connections to
the seat switch, the blade clutch switch and
the electric blade clutch. Then check out
the seat switch, the blade clutch switch and
finally the electric blade clutch.

Inflation Pressure:
a. Traction Tires—20 psi max; 8-10 psi recommended
b. Front Caster Wheel—28 psi max; 20-25
psi recommended
c. Cutting Deck Ball Wheels—Solid Polyurethane.
Use the Following guidelines for maintaining the tires:
a. Balance inflation pressure between the
rear tires to help maintain straight travel
(see tire side wall for proper inflation pressure).
b. Keep the valve caps tightened to prevent
air pressure loss.
2.
Leaking Tires: When a flat tire occurs, repair
or replace immediately. The normal procedure
is to remove the wheel and replace it with a
spare. Take the leaking tire to a maintenance
area and repair. If a tire is getting soft, park
the mower on the nearest level, paved area. If
the leaking tire is on a traction wheel, put
blocks on each side of the opposite traction
wheel and jack up the tire that leaks about an
inch off the ground. Loosen and remove the
lug nuts and remove the wheel. Mount a
spare wheel and tire, replace the lug nuts, and
using a torque wrench, tighten them to 60 ±
10 ft-lbs.
If the leaking tire is on a front caster wheel,
block both traction wheels and raise the
caster wheel so that the tire is an inch off the
ground. Loosen and remove the locknut from
the axle assembly and pull the axle assembly
from the caster yoke. The wheel and two
spacer sleeves will drop free. Slip the axle
assembly through one side of the caster
yoke, through a spacer sleeve, a spare
wheel, the other spacer sleeve and finally
through the other side of the caster yoke.
Then tighten the locknut on the end of the
axle assembly.
Lower the mower off the jack and continue
mowing. The wheel with the leaking tire
should be taken to the maintenance area, the
tire inflated to 20 psi and the wheel placed in
a large bucket of water. Carefully inspect the
tire, rim and valve for escaping air bubbles
which indicate a leak. Mark each leak with a
yellow marking crayon and then deflate the
tire to 8 psi and repeat the inspection. If the
leaks you find are pin hole size to 1/16"
diameter, the tire can be repaired using an
aerosol can of tire inflater and latex sealer
D.Tires
The two front wheels are caster wheels that are free
to swivel to accommodate the direction of the Mower.
The two rear wheels are used to propel the Mower in
the direction of input from the drive handles. Inflation

available from any auto supply store. Follow
the directions on the can. If the leaks are
larger than 1/16" diameter, the tire can be
repaired with rubber plugs also available in a
kit from any auto supply store. If the tire bead
is damaged, a tube will have to be installed in
the tire or the tire will have to be replaced.
2.
Repair: The mower is equipped with drum
brakes and will not normally require maintenance. If they are not working properly, please
contact your service center.
F. Hydraulic System
WARNING:
3. Creeping: Creeping is the slight forward or
backward movement of the mower when the
throttle is on and the lapbars are in the neutral
position. If your mower creeps, refer to Steering Lever Adjustment Section F4, page 23.
Never overfill the hydraulic units. Damage can
occur if the oil level is not within the proper
operating range.
Note: When adding hydraulic oil, do so in
small quantities and recheck the oil level
before adding more. It is important that you do
not overfill the reservoir to allow for fluid
expansion.
E. Brakes
While the mower is in motion, all braking is performed
dynamically through the hydraulic pumps and traction
motors, controlled by the two steering levers. When the
mower is stationary with the engine running, the
hydraulic system locks the traction wheels. If the engine
is shut off, the park brake should be engaged.
1.
Note: To move the mower forward or in
2.
reverse by pushing, you must release the
dynamic braking. Locate the valves on the
pump. Turn valves counter-clockwise (using a
standard 7/16” wrench) one quarter turn to push
the unit. After pushing the mower to the desired
location, return both valves to the operating
position by turning the valve clockwise, but do
not overtighten(See photo below).
Hoses: Check the hoses from the hydraulic
oil tank to the oil filter to the hydraulic lines
daily for leaks or abrasion and replace any
damaged hoses. Make certain there are no
kinks or twists in any hose.
Hydraulic Oil Tank and Filter:
Note: Change the hydraulic oil and the oil
filter element after the first 50 hours of operation and every 500 hours thereafter.
To drain the hydraulic oil tank, place a 1 gallon drain
pan under the drain plug on the bottom of the
hydraulic oil tank. Remove the drain plug, drain the
tank, then replace the plug. Remove the three screws
from the top of the oil filter and take out the oil filter
element You don’t have to drain the rest of the
hydraulic system. Put the replacement filter element
in the oil filter and lubricate the sealing surface. Install
the three screws in the top of the oil filter to secure
the oil filter element. (See photo below)
Bypass
Valve

Left Side Pump
When the mower is parked with the engine running
and the steering levers in the neutral position, the
parking brakes should be applied. The parking brakes
are drum-type brakes mounted on each traction
wheel. They are both engaged by the same operating
lever.
1.
Screw
Adjustments: The parking brake handle is an
overcenter lever that should engage with
moderate force.
Note: Always wipe off the hydraulic tank fill
cap and the area around it before removing
the cap to prevent dirt from contaminating the
oil.
Note: To increase parking brake capacity,
adjust brake cables at the brake arms equally.
Adjust the cable housing nuts one full turn
and check parking capacity. Repeat if parking
brake does not hold.
Remove the fill cap and fill the tank with the same
15W-40 oil selected for the filter until the oil level is a
1/4” below the oil tank fill neck. Leave this air space
22
for expansion. Start the engine and let it run at idle for
about five minutes. Check the filter for leaks. Idling the
engine and the pumps in this way will purge any air
from the system. Shut off the engine and recheck the
oil level in the tank. Top-off if necessary until the oil
level is a 1/4” below the oil tank fill neck.
feature with hydraulic dampers to provide
smooth, non-jerkey, control motion while
affording an automatic hydrostatic braking
means.
Whenever the Park Brake lever is moved rearward to the Park Brake engaged position, a
cable mechanism, connected to each drum
brake on the hydrostatic wheel motors,
applies force to each brake lever so that each
wheel brake mechanism can prevent brake
drum and wheel rotation. At the same time, a
second cable and linkage mechanism is activated to secure both lap bars in their Neutral
positions and to activate the Park Brake
switch. Both lap bars must be in their Neutral
positions for the neutral lock linkage to function - the spring-loaded linkage will force rods
in through aligning holes in each lap bar
whenever the lap bars are in their Neutral
positions.
Note: After unit is up to operating temperature, turn off engine and re-check hydraulic
oil. If oil appears foamy or contains excessive
air bubbles, DO NOT OPERATE UNIT. Contact
service technician.
3. Hydrostatic Pumps and Motors: The pumps
are the hardest-working components in the
hydraulic system. They are in operation all the
time the engine is running. Because of
extremely close tolerances, wear is an important factor in their life. Contaminants in the
hydraulic oil and cavitation does the greatest
harm to the pumps. Cavitation is a blockage in
the supply lines that produces a partial vacuum causing violent bubbling in the hydraulic
oil in the pump.
Note: Both lap bars must be in their Neutral
positions for the Park brake interlock mechanism to function so as to prevent lap bar
movement (movement that would activate the
hydrostatic pumps producing Forward or
Reverse travel rotation of the wheel motors)
and to allow the Park Brake switch to be activated.
Check the two suction hoses (the hoses connected to the filter) daily before starting the
engine. Look for a flattened condition or any
leaks and repair or replace as necessary. A
flattened or leakng suction hose will permit
cavitation to develop which can destroy the
pumps in a short time.
Whenever the Park Brake is applied (I.E., the
Park brake lever moved completely rearward
in the control panel slot), the lap bars should
be secured in their Neutral positions by the
linkage rods moving into the holes in the lap
bars. This lap bar Neutral lock mechanism
also activates the Park brake switch, which
allows for the engine to be started. If the lap
bars are in their Neutral positions, and they
are not “locked” so as to prevent movement
when the Park brake is applied, then the linkage from the RTN on the hydrostatic pumps
and the lap bars must be adjusted. This is
done by determining which side (or both) rod
is not aligned to the hole in the lap bar, then
locating that side linkage rod turn-buckle at
the hydrostatic pump RTN, loosening the jam
nuts and lengthening or shortening the linkage rod so that the rod snaps into the hole in
the lap bar.
Contaminants or foreign matter in the oil will
also damage the pumps . To prevent this, use
a filter that captures particles as small as 25
microns or 25 millionths of a meter in diameter. You can help in the battle against dirt by
being very careful when you remove or repair
a component in the hydraulic system. Thoroughly clean off any component before you
work on it. Plug the ends of any hose or line
you remove with a rubber or plastic plug. Use
plastic caps to seal off the ends of hydraulic
fittings. Place any component you remove in a
clean plastic bag so it can’t pick up dust or
dirt. Clean your hands frequently when working on the hydraulic components.
Note: The pumps are not owner-repairable.
If a pump fails, contact your Cub Cadet Commercial dealer. Do not disassemble the pump.
4.
Steering Lever Adjustments: The steering
lever controls on this Zero Turn Mower (ZTM)
incorporate a patented interlock mechanism
that secures them in their Neutral position
whenever the Park Brake lever is applied.
Additionally, the lap bars can be opened in
any position - Neutral, when traveling Forward, when traveling in Reverse, or when executing a zero-turn maneuvar. The lap bars
also incorporate a Return-To-Neutral (RTN)
Dampers are incorporated into the lap bar
linkage to provide smooth, non-jerkey, control
action. The damper rate can be adjusted by
relocating the damper - lower to reduce the
damper action, and elevate to increase.
Note: The engine should be able to be
started whenever the Park Brake is applied,
and the lap bars are locked in their Neutral

i.
Inspect the hydraulic hoses, lines and fittings. Replace as necessary.
j. Jack the mower up and store it on blocks to
take the weight off of the tires.
2. To Put the Mower Back in Service:
a. Check the battery. Charge if necessary.
b. Gasoline Engine Only: Remove the spark
plugs and wipe them off. Using the starter,
crank the engine to pump the excess oil
out of the spark plug holes. Replace the
spark plugs and the ignition leads. Refill
the fuel tank with fresh gasoline.
c. Check the level of the oil in the crankcase
and the hydraulic tank.
d. Lower the mower off the block and check
the tire pressure.
e. Push the mower outdoors and start the
engine. Let the engine idle until it has
warmed up completely (4 to 5 minutes).
positions - if not, the switch may need to be
adjusted or replaced.
Whenever the ZTM is on level ground with the
engine running and the lap bars in their Neutral positions, the ZTM should not creep (I.E.,
move in the Forward or Reverse directions of
travel). If this occurs, contact your Service
representative for the procedure to reset the
RTN mechanism on the hydrostatic pumps. If
the hydrostatic pump RTN is adjusted, the
control linkage must also be readjusted.
G. Storage
1. General: If your mower will not be in service
for a few months, it should be stored in a dry
location that is not subject to drastic changes
in temperature. Before storing, the following
maintenance procedures should be performed.
Note: For E.F.I. Tanks, disconnect the negative lead of the battery for storage of 4 weeks
or more.
a. Clean the mower. The entire tractor and
cutting deck should be washed and
cleaned.
b. Sharpen the blades so that the mower will
be ready to use when needed.
c. Protect the metal surfaces. Repair
scratches with the appropriate touch-up
spray paint. Brush a rust preventive oil on
any unpainted surfaces including the pulleys and blades. (Be careful not to get any
oil on the drive belts.)
d. Lubricate the mower.
e. Drain the engine oil. The engine should be
warm so that all the oil drains. Replace the
engine oil filter and refill the crankcase with
fresh oil.
f. Gasoline Engine: Drain all the fuel. Close
the fuel tank shutoff valve. Disconnect the
fuel line from the carbuetor and put the end
into an approved fuel container. Open the
fuel tank shutoff valve and drain the fuel
tank and line into the approved container.
Replace the fuel line on the carburetor.
Start the engine and allow it to run out of
fuel. This will prevent gum and varnish
deposits from forming. Replace the fuel filter.
g. Gasoline Engine Only: Remove the spark
plugs and pour approximately one ounce
of oil into each cylinder. Crank the engine
one or two turns to spread the oil evenly on
the cylinder walls. Replace the spark
plugs.
h. Disconnect, clean and make sure the battery is fully charged.

bolt.
Verify that the lap bars are in the neutral position, the parking brake is on, and the PTO
drive is disengaged.
Start the mower and let it run at approximately
half throttle for 3-5 minutes to bring the engine
up to operating temperature.
Locate the Hour Meter/Tachometer/ Service
Minder display on the right hand operator control panel. (see Fig.1 on page 8 of the manual)
This display defaults to Tachometer mode
when engine is running.
Move the throttle lever to the high speed position and note the RPM reading on the display.
Move the throttle lever back to the low speed
position and again note the displayed RPM’s.
Compare these noted RPM readings to the
specifications in Table 1, for the engine that is
on your mower.
If the readings do not correspond to the
ranges in the table, refer to the engine
owner’s manual for the proper adjustment procedures.
If adjustments per the engine operator’s manual do not result in proper RPM readings, contact your service technician.
Note: The throttle cable sheath may shrink or
slip over time, changing the relationship
between the throttle lever on the left hand
operator control panel and the throttle arm on
the engine. To readjust the throttle cable:
a. Make sure the engine is off, place lap bars
in the neutral position, set the parking
brake, and disconnect and ground both of
the spark plug wires.
b.

Locate and loosen the cable clamp on the
engine throttle plate.
c. Place the operator’s throttle lever to the
high speed position and then slide the
cable through the clamp until the throttle
arm is in the full throttle position. (Ref.
Engine owner’s manual)
d. Tighten the cable clamp.
e. Move the operator’s throttle lever between
high and low speed and verify that the
engine throttle arm also moves through it’s
full range of motion.
f. Repeat as required to obtain proper throttle adjustment.

C. Deck Corner Ball Wheel Roller Settings
Note: If lap bar adjustments are required,
1.
Matching the set heights of the ball rollers on
the four corners of the mower deck to the
desired cut height will prevent edge scalping
and minimize any side-to-side variance in cut
height.
2. There are three height adjustment holes in
the bracket that mount the ball rollers to the
deck.
a. Use the top set of holes for cut heights of 2
inches or lower.
b.
c.
The seat has five inches of front-to-rear
adjustment available.
Check factory settings of lap bars for the conditions listed above.
height adjustments should be made prior to
angular adjustments.
5.
To adjust the height of the lap bars,
a. Remove the nuts from the lap bar mounting
bolts (see Fig. 11).
b. Remove the bolts and lap bar and repostion
to the seconc set of holes in the mounting
block.
c. Replace the bolts and nuts and tighten to
28-34 ft-lbs.
1. If angular adjustments are also required,
nuts can be tightened until snug at this
point.
d. The same adjustments should be made to
both sides of the mower.
6. To adjust the front-to-rear angle of the lap bars,
a. Loosen the nuts on the lap bar mounting
bolts, leaving the bottom one fairly snug.
b. The top hole is slotted, allowing the lap bar
to pivot on the bottom bolt.
c. Move lap bar to the desired angle and
tighten the nuts to 28-34 ft-lbs.
Use the middle set of holes for a 2-1/2 - 3-1/2
inch cut height.
Use the bottom set of holes for cut heights of
4 inches or higher.
D. Deck Center Anti-Scalp Roller Settings
1.
The front and rear rollers help prevent the
scalping of high spots and uneven terrain
across the center section of the deck.
2. The rollers on the front of the deck are fixed at
the factory and can not be adjusted.
3. The rollers on the rear of the deck can be
adjusted downward one inch.
a. Lowering the roller will increase the striping effect left behind the mower.
b. This positioning of the rear roller will also
help to filter the mulched grass clippings
into the turf.
c. Roller should not be lowered if the cut
height is set at 2-1/2 inches or lower.
Note: In the neutral position, the handles of
the lap bars should be aligned with approximately a one inch gap between the tips. Adjusthe gap by adding shim washers to the top
mounting bolt between the lap bar and the
mounting block.
d. Check the results of any adjustments to
the conditions described in section a,
above. Repeat any adjustment procedures
as required until all conditions are met.
E. Lap Bar Adjustment
1.
Proper lap bar and seat adjustment will result
in the following:
a. In the neutral position with hands on the
lap bars,
1. Operator’s upper arms should be relaxed
and approximately vertical.
2. Operator’s forearms should be approximately vertical.
b. In the full forward position,
1. Operator’s back should stay in contact
with the seat back.
2. Lap bars should not contact operator’s
legs.
c. In the full reverse position,
1. Lap bars should not contact the operator’s legs or torso.
2. Set the seat to the preferred operating position.
a. Adjustment lever is located under the front
edge of the seat.

aligned along the mower centerline. The bladeto-ground height at the rear of the blade tip
should be 1/8" to 1/4” higher than the front tip.
This is referred to as blade pitch. The sam
height difference should be true for the left
blade, measured front and back.
8. To adjust the blade pitch the deck pitch must be
adjusted. Loosen the inner jam nuts at the rear
of the horizontal threaded rods. Start at Point C
to raise the rear of the deck, tighten the rear
outer jam nut to raise the deck pitch. Adjust the
rear jam nut at Point D to take the “slack out of
the threaded rod.
9. The final adjustment would be to take the “slack”
out of the left rear linkage (Point D) by adjusting
the jam nuts on the eyebolt. Loosen the jam
nuts and tighten the upper nut to remove “slack”.
10. In many cases it will be necessary to adjust
deck height using both eyebolt adjustments and
pitch adjustment to achieve the correct blade-toground heights. If you remember that the front
right blade tip adjustment is fixed and you level
to that height, adjusting the decks will be simplified.
11. Once the deck is level one may find that the
height of cut does not match the height of cut
indicator. A final adjustment may be made by
lowering or raising the height of cut link accordingly. To raise the deck: remove the shoulder
bolt mounting the height of cut link to the lift handle and reassemble the shoulder bolt in the lowest of the three holes. To lower the deck: remove
the shoulder bolts mounting the height of cut
link, flip the height of cut link around and reassemble the shoulder bolts in the top of the set of
three holes and the bottom hole. (see Fig. 12)
Park the mower on a flat paved surface, engage
the parking brake, shut off the engine, remove
the key from the ignition switch, disconnect the
spark plug wires and using the foot pedal, lower
the mowing deck into the 4" height of cut position. (The 4" height of cut position is recommended in order for one to see and obtain a
measurement. Any height of cut position is
acceptable as long as a proper measurement
can be taken.)
Check the right and left front tire pressure.
Adjust as necessary to 20-25 psi. Tire pressure
can affect blade height by as much as a 1/4”.
Check the right and left rear Drive tire pressure.
Adjust as necessary to 8-10 psi.
Measure blade-to-ground height at the front tip
of the right blade. To obtain an accurate measure, align blades in parallel with mower centerline, (i.e. front to back).
Measure blade-to-ground height at the front tip
of the left blade. Be sure to measure at the
blade tip with the blades arranged in proper
position.
To level the deck, adjust the eyebolt at the left
front of the deck (Point B) so that the blade-toground height at the right front blade tip
matches that of the left front blade tip. This is
done by loosening the jam nuts on the eyebolt
and tightening the upper nut to raise the deck
and loosening the nut to lower the deck. The
right front blade tip height is fixed so you must
adjust the left front tip to match it.
Measure the blade-to-ground height at the right
rear blade tip. Again be sure to measure at the
blade tip at the rear of the right blade when
