Important: If the operator cannot
read English or Spanish, the owner
is responsible for explaining the
information in this manual.
2. Be completely familiar with the controls
and the proper use of this machine
before operating it.
3. This machine is a precision piece of power
equipment, not a plaything. Therefore,
exercise extreme caution at all times. This
machine has been designed to perform
one job: to mow grass. Do not use it for
any other purpose.
4. Do not allow anyone to operate or
maintain this machine who has not
read the manual. Never allow children
under 16 years of age to operate
this machine.
5. Only responsible individuals who
are familiar with these rules of safe
operation should be allowed to use this
machine. The owner is responsible for
training the users, and is responsible
for accidents or injuries occurring to
themselves or others.
6. Thoroughly inspect the area where the
equipment is to be used. Remove all
stones, sticks, wire, bones, toys, and
other foreign objects, which could be
tripped over or picked up and thrown
by the blade. Thrown objects can cause
serious personal injury.
7. Plan your mowing pattern to avoid
discharge of material toward roads,
sidewalks, bystanders, and the like. Also,
avoid discharging material against a
wall or obstruction, which may cause
discharged material to ricochet back
toward the operator.
8. To help avoid blade contact or a thrown
object injury, stay in operator zone
behind handles and keep children,
bystanders, helpers, and pets at least
75 feet (23 meters) from mower while it
is in operation. Stop machine if anyone
enters area.
9. Always wear safety glasses or safety
goggles during operation and while
performing an adjustment or repair
to protect your eyes. Thrown objects
which ricochet can cause serious injury
to the eyes.
10. Wear sturdy, rough-soled work shoes
and close-fitting slacks and shirts. Shirts
and pants that cover the arms and legs
and steel-toed shoes are recommended.
Never operate this machine in bare feet,
sandals, slippery, or light-weight (e.g.
canvas) shoes.
11. Do not put hands or feet near rotating
parts or under the cutting deck. Contact
with blade can amputate fingers, hands,
toes, and feet.
12. A missing or damaged discharge cover
can cause blade contact or thrown
object injuries.
13. Many injuries occur as a result of the
mower being pulled over the foot during
a fall caused by slipping or tripping.
Do not hold on to the mower if you are

3Section 1 — Safe operation practiceS
35. When operating this machine in the
forward or reverse direction, do not
allow the ground speed control 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.
36. If situations occur which are not covered
in this manual, use care and good
judgement. Contact Customer Support
for assistance or the name of the nearest
service dealer.
Slope Operation
Slopes are a major factor related to slip and
fall accidents, which can result in severe injury.
Operation on slopes requires extra caution. If
you feel uneasy on a slope, do not mow it. For
your safety, use the slope gauge included as
part of this manual to measure slopes before
operating this machine on a sloped or hilly
area. If the slope is greater than 15° (25%), do
not mow it.
Do:
1. Mow across the face of slopes; never up
and down. Always turn up hill. Exercise
extreme caution when changing
direction on slopes.
2. Watch for holes, sprinkler heads, ruts,
rocks, hidden objects, or bumps which
can cause you to slip or trip. Tall grass
can hide obstacles.
3. Always be sure of your footing. A slip
and fall can cause serious personal
injury. Check the area thoroughly before
mowing. Slow down and use extra care.
Do Not:
1. Do not mow near drop-offs, ditches
or embankments, you could lose your
footing or balance.
2. Do not mow slopes greater than 15°
(25%) as shown on the slope gauge.
3. Do not mow on wet grass. Unstable
footing could cause slipping.
WARNING
Do not mow up and down the slope. You could slip and
slide into the mower, or the mower could lose traction
and steering control.
Children
Tragic accidents can occur if the operator is not
alert to the presence of children. Children are
often attracted to the mower and the mowing
activity. They do not understand the dangers.
Never assume that children will remain where
you last saw them.
1. Keep children out of the mowing area
and under watchful care of a responsible
adult other than the operator.
2. Be alert and turn mower off if a child
enters the area.
3. Before and while moving backwards,
look behind and down for small children.
4. Use extreme care when approaching blind
corners, doorways, shrubs, trees, or other
objects that may obscure your vision of a
child who may run into the mower.
5. Keep children away from hot or running
engines. They can suffer burns from a
hot muffler.
6. Do not allow anyone to operate or
maintain this machine who has not read
the manual. Never allow children under
16 years of age to operate this machine.
Hydraulic Devices & Systems
Hydraulic fluid escaping under pressure may
have sufficient force to penetrate skin and to
cause serious injury. If foreign fluid is injected
into the skin, it must be surgically removed
within a few hours by a doctor familiar with this
form of injury, or gangrene may result.
WARNING
Keep body and hands away from pinholes or nozzles
that could eject hydraulic fluid under high pressure.
Use paper or cardboard, not hands, to search for leaks!
Safely relieve all pressure in the system before
performing any work on the system, and make
sure that:
• The ignition switch is OFF
• The key is removed
• The engine spark plug wire(s)
are removed
• All connections to the negative terminal
of the battery are removed
• The park brake is set
• All by-pass valves, if so equipped, are open
• Hydraulic controls are actuated to release
pressure on pumps, cylinders, etc. If “float”
positions are available, they should be used
After the above operations are completed, it
should be safe to begin disconnecting the lines
or components. It is still a good idea to cover
the connection with a cloth shield and then
gently loosen connections.
WARNING
Make sure all hydraulic fluid connections are tight
and all hydraulic hoses and lines are in good condition
before applying pressure to the system.
Service
Safe Handling Of Gasoline:
1. To avoid personal injury or property
damage use extreme care in handling
gasoline. Gasoline is extremely
flammable and the vapors are explosive.
Serious personal injury can occur when
gasoline is spilled on yourself or your
clothes, which can ignite. Wash your skin
and change clothes immediately.
2. Use only an approved gasoline container
and fill slowly to decrease the chance of
static electricity buildup and spillage.
3. Never fill containers inside a vehicle or on
a truck or trailer bed with a plastic liner.
Always place containers on the ground
away from your vehicle before filling.
4. Remove gas-powered equipment from
the truck or trailer and refuel it on the
ground. If this is not possible, then
refuel such equipment on a trailer with
a portable container, rather than from a
gasoline dispenser nozzle.
5. Keep the nozzle in contact with the rim
of the fuel tank or container opening at
all times until fueling is complete. Do not
use a nozzle lock-open device.
6. Extinguish all cigarettes, cigars, pipes,
and other sources of ignition.
7. Never fuel machine indoors because
flammable vapors will accumulate in
the area.
8. If the fuel container spout will not fit
inside the fuel tank opening, use a funnel.
9. If the fuel tank has to be drained, do
this outdoors.
10. Never remove gas cap or add fuel while
engine is hot or running. Allow engine to
cool at least 5 minutes before refueling.
11. Never over fill fuel tank. Fill the tank to
the bottom of the filler neck, allowing
some space in the tank for fuel expansion.
12. Replace gasoline cap and tighten securely.
13. If gasoline is spilled, wipe it off the
engine and equipment. Move machine
to another area. Wait 5 minutes before
starting engine.
14. Never store the machine or fuel
container near an open flame, spark, or
pilot light as on a water heater, space
heater, furnace, clothes dryer, or other
gas appliances.
15. To reduce fire hazard, keep machine free
of grass, leaves, or other debris build-up.
Clean up oil or fuel spillage and remove
any fuel soaked debris.
16. Allow machine to cool at least 5 minutes
before storing.
General Service:
WARNING
Never let children or untrained people operate or service

Mower features may vary by model. Not all features
in this manual are applicable to all mower models
and the mower depicted may differ from yours.
Key Switch (A)
The key switch is located on the console to
the rear of the hour meter. The key switch has
three positions on electric start models and two
positions on recoil start models.
OFF/STOP — The engine and electrical
system are turned off/stopped.
ON — On recoil starter models, the mower
electrical system is energized and the engine
can be started using the recoil starter. On
electrical starter models, the mower’s electrical
system is energized and the engine is running.
START (electric start models only)— The
starter motor will turn over the engine.
Release the key immediately when the
engine starts.
Note: To prevent accidental starting and/or battery
discharge, remove the power key from the key
switch when the mower is not in use.
Choke Knob (B)
The choke knob is located on the control panel
below the throttle control lever and to the left of
the PTO knob. The choke is engaged by pulling
upward on the choke knob. Engaging the choke
closes the choke plate on the carburetor and aids
in starting the engine. To disengage the choke,
push the choke control knob down fully.
Throttle Control Lever (C)
The throttle control is located on the middle of
the control panel and is used to control engine
speed. Moving the throttle control upward/
forward will increase the engine speed from
slow to fast.
PTO (Power Take-Off) Knob (D)
The PTO knob is located on the center, bottom, the
control panel and is used to engage the mowing
deck. To operate, lift the PTO knob up fully. To stop
the blades, push the PTO knob down fully.
FAST
S L O W
Steering Levers (E)
The steering levers are located under the left and
right handles. When the levers are released, the
mower will move ahead in a straight line if the
engine is running and the transmission is engaged
in a forward gear. Steering is accomplished by
squeezing the steering/brake lever on the side to
which the turn is to be made. A slight lever squeeze
will provide a gentle turn. Squeezing the lever
more will provide a sharper turn and continued
lever squeezing will apply the brake providing a
pivot turn. The middle detent position of the levers
is neutral (N), pulling the lever past this detent
position will cause the wheel on that side of the
mower to move in reverse. Pulling both levers
completely against the handle will move the mower
in reverse.
Neutral Latch Levers (F)
Pivoted inside each handle, there is a neutral latch
lever which works with each of the steering levers.
When either of the steering levers is squeezed and
its neutral latch lever pushed forward and engaged
in the neutral lock position, the wheel on that side
of the unit will stop moving. When both steering
levers are squeezed and both neutral latch levers
are pushed forward and engaged in the neutral lock
position, the unit will stop moving.
Operator Presence Levers (G)
The operator presence levers are located above
the right and left handles. At least one of these
operator presence levers must be held down on
the handles in order to engage the shift lever or
PTO. Releasing the operator presence levers with
either the shift lever in gear (out of neutral) or PTO
engaged will shut off the engine.
Important: One or both operator presence levers
must be depressed when in gear or mowing.
Parking Brake Lever (H)
The parking brake lever is located on the
left of the front panel of the mower, and
when pulled upward, engages the parking
brake. Do not engage the parking brake
while moving.
Note: If the speed control lever is not fully
in the neutral position when engaging the
parking brake, the engine will stop.
Speed Control Lever (I)
The speed control lever is located in the
center of the control panel between the
throttle control lever and the hour meter. It
is used to control the speed of the mower
independent of the engine speed. Moving
the lever forward increases the speed of the
mower. The range of speed is from neutral
(N) to six (6) which is the fastest speed.
Important: In order to start the engine the
lever must be pulled back to the neutral
(N) position.

Operating on Slopes
Refer to the slope gauge in the Safe Operation
Practices section to help determine slopes where
you may safely operate the mower.
WARNING
Do not mow on inclines with a slope in excess of 15° (25%) (a
rise of approximately 2-1/2 feet every 10 feet). The mower
could overturn and cause serious injury.
• Mow across the face of slopes; never up
and down.
• Exercise extreme caution when changing
direction on slopes.
• Watch for holes, ruts, rocks, hidden objects or
bumps which can cause you to slip or trip. Tall
grass can hide obstacles.
• Always be sure of your footing. A slip and fall
can cause serious personal injury.
• Do not mow near drop-offs, ditches or
embankments, you could lose your footing
or balance.
• Do not mow slopes greater than 15° (25%) as
shown on the slope gauge.
• Do not mow on wet grass. Unstable footing
could cause slipping.
Setting Deck Height
To adjust the deck height, adjust the clevis pin
location in the deck adjustment pins and the deck
lift adjustment collars.
1. Securely grasp one of the three handles on

(b)
(c)
Figure 3-3
2. Raise or lower the deck on the deck
adjustment pin (b) and in combination with
the deck lift adjustment collar (c), find the
desired height. See Figure 3-3.
3. Insert the cotter pin (a) back into the deck
adjustment pin (b) at the desired position.
See Figure 3-3.
4. Repeat these steps for the other three deck
adjustment pins making sure the height is
the same for all four deck adjustment pins.
Mowing
The following information will be helpful when
operating your mower.
WARNING
Plan your mowing pattern to avoid discharge of materials
toward roads, sidewalks, bystanders, and the like. Also,
avoid discharging material against a wall or obstruction
which may cause discharged material to ricochet back
toward the operator.
• Be sure area is clear of rocks, sticks, toys, wire
or other objects that could be thrown by the
mower. Survey the entire area to be mowed.
Make sure that the accessories and attachments
would be suitable for use on the terrain.
• Use care when approaching blind corners,
shrubs, trees or other objects that could
obstruct vision.
• To mow grass and produce a striped pattern:
• Pick a point on the opposite side of
the area to be mowed (post, tree,
shrub, etc).
• If on a hillside, start at the bottom
so that the turns are uphill rather
than downhill.
• Align the mower so as to head
directly toward the object on the
far side.
• 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.
• When approaching the other end
of a strip, slow down or stop before
turning. A U-turn is recommended.

11Section 3 — controlS & operation
• To prevent rutting or grooving of the
turf, change the direction that the
strips are mowed by approximately
45° the next and each subsequent
time that the area is mowed.
• If the grass is repeatedly mowed
in the same direction, it will be
“trained” so that the striped
appearance is more pronounced and
longer lasting. Grooving of the turf
from the tires will occur.
• For emptying material collection systems or
for any other operation involving the mower
deck, before leaving the operator station:
• Disengage the mower blades.
• Squeeze the steering controls and
latch the neutral locks.
• Place the gear shift lever in neutral.
• Shut off the engine.
• Apply wheel chocks and/or engage
the parking brake.
Transporting Mower
• If ramps are used, be sure they are secured to
the trailer, truck bed, etc. and are designed
for the application.
• The mower should be pushed or pulled onto
or off the trailer, truck bed, etc., never try to
drive it on.
• Engage the parking brake, secure mower
with chocks, straps, etc.
• Make sure accessories and attachments are
secured or removed.

13Section 4 — Product care
Note: This Operator’s Manual covers several
models. Mower features may vary by model.
Not all features in this manual are applicable
to all mower models and the mower depicted
may differ from yours.
WARNING
Before performing any maintenance or repairs, disengage
the PTO, engage the parking brake, stop the engine, and
remove the key to prevent unintended starting.
Post-Operation Mower Care
After each operation of the mower, the
following procedures should be implemented
to extend the life of your mower and ensure safe
operating conditions.
DANGER
Failure to follow these recommendations may result
in serious injury to yourself or others and may cause
damage to the mower.
Cleaning the Underside of the Deck
Rinse grass clippings from the deck’s underside
and prevent the buildup of corrosive chemicals.
WARNING
Make certain the mower’s discharge chute is directed
AWAY from people, your house, garage, parked cars, etc.
1. Disengage the PTO, set the parking
brake and stop the engine.
2. Use a hose to spray the underside of
the deck.
Note: Make sure that the hose is not
routed under the deck and is clear of all
moving parts.
3. After cleaning your deck, return to the
operator’s position and engage the PTO.
Keep the deck running for a minimum of
two minutes, allowing the underside of the
deck to thoroughly dry.
Cleaning the Mower
WARNING
If the mower has been recently run, the engine,
muffler, and surrounding metal surfaces will be hot
and can cause burns to the skin. Let the engine cool for
at least 5 minutes. Exercise caution to avoid burns.
Your mower should be cleaned after each use
and under certain conditions, i.e. dry conditions
and/or mulching situations, additional cleaning
may be necessary.
One of the best ways to keep your mower
running efficiently and to reduce fire risk is to
regularly remove debris buildup from the mower.
Follow the recommendations below and contact
your authorized dealer with any questions.
• Allow the machine to cool in an open
area before cleaning.
• Do not use water on any part of the
mower except the underside of the
cutting deck. Doing so can cause
damage to the mower’s spindle
bearings, electrical system and engine,
leading to premature failures. The use of
compressed air and/or leaf blower will
help keep the mower clean.
• Clean around the exhaust manifold, fuses,
all wiring and harnesses, muffler pipe,
muffler shield, engine intake screens and
cooling fins, etc. See Figure 4-1.
Figure 4-1
• Clean the top of the mower deck, under
the spindle covers and belt area. See
Figure 4-2.
Figure 4-2
• Clean around and near the transmission,
axle and the fan area. See Figure 4-3.
Wheel Not Shown For Clarity
Figure 4-3
• Debris can accumulate anywhere on the
mower, especially on horizontal surfaces.
Additional cleaning may be necessary
when mowing in dry conditions or
when mulching.
• Fuel leaks/spills, oil leaks/spills and
excess lubrication can also become
collections sites for debris. Immediate
repair and cleaning up oil or fuel spills
can help reduce fire hazards.
• In addition to cleaning the mower
before operating and storing, do not
attempt to mow unusually tall grass (10”
or higher), dry grass (e.g., pasture) or
piles of dry leaves. Dry grass or leaves
may contact the engine exhaust and/or
build up on the mower deck presenting
a potential fire hazard.
Storing the Mower
• Allow the machine to cool in an open
area before storing.
• Do not park the mower near any
flammable materials (wood, cloth or
chemicals) or any open flames or other
potential source of ignition (furnace,
water heater or any other type of heater).
• Remove all combustible materials from
the mower before storing. Empty cargo
boxes, grass catchers or containers.
• Always shut off fuel flow when storing or
transporting if mower is equipped with
a fuel shutoff.
• Check the fuel system (lines, tank, cap
and fittings) frequently for cracks or
leaks. Repair and clean as necessary.
Maintenance
Engine
Refer to the Engine Operator’s Manual for all
engine maintenance intervals, procedures,
specifications and instructions.
Changing the Engine Oil
WARNING
If the engine has been recently run, the engine,
muffler, and surrounding metal surfaces will be hot
and can cause burns to the skin. Exercise caution to
avoid burns.
Maintain oil level as instructed in Engine
Operator’s Manual. Be careful not to spill oil on
any of the belts.
To complete an oil change, proceed as follows:
1. Run the engine for a short time to warm
the engine oil. The oil will flow more
freely and carry away more impurities.
Use care to avoid burns from hot oil.
2. Locate the oil drain hose on the engine.
See Figure 4-4.
Figure 4-4
3. Route the free end of the oil drain hose
toward an appropriate oil collection
container with at least a 2.5 quart
capacity, to collect the used oil.
Note: Avoid getting oil on the muffler
when draining.
4. While holding the free end of the
oil drain hose over the oil collection
container, unscrew the square-head
hose plug from the end of the hose. See
Figure 4-4. Drain the engine oil into the
collection container.
5. Remove the oil filter to make sure all the
oil is drained.

14 Section 4— Product care
6. After draining the oil, wipe any residual
oil from the oil drain hose. Thread the
square head plug into the drain hose
fitting and fully tighten the plug.
7. Replace the oil filter and refill the
engine with new oil as instructed in the
Engine Operator’s Manual. Refer to the
Engine Operator’s Manual for information
regarding the volume and weight of
engine oil.
8. Route the hose back along the frame as it
was before removal.
Lubrication
Periodically lubricate all pivot points with a
quality lubricating oil.
Tires
Check the tire air pressure after every 50 hours
of operation, or weekly. Keep the tires inflated
to the recommended pressures. Improper
inflation will shorten the tire service life and
produce an uneven cut. The recommended
operating rear tire pressure is 12 psi. Observe
the following guidelines:
• Do not inflate a tire above the maximum
pressure shown on the sidewall of the tire.
• Do not reinflate a tire that has been run flat
or seriously under-inflated. Have it inspected
and serviced by a qualified tire mechanic.

Alwaysshield eyes andprotect skinand clothingwhen
workingnear batteries.
Batteries containsulfuric acidand may emitexplosive gases.
Do NOTopen battery.Use extreme cautionwhen handling
batteries. Keep batteries out of the reach of children.
Battery Maintenance
• The battery is filled with battery acid and
then sealed at the factory. However, even a
“maintenance free” battery requires some
maintenance to ensure its proper life cycle.
• Spray the terminals and exposed
wire with a battery terminal sealer, or
coat the terminals with a thin coat of
grease or petroleum jelly, to protect
against corrosion.
• Always keep the battery cables and
terminals clean and free of corrosion.
• Avoid tipping. Even a sealed battery will
leak electrolyte when tipped.
WARNING
Batteries contain sulfuric acid and may emit explosive
gases. Use extreme caution when handling batteries.
Keep batteries out of the reach of children.
Battery Storage
1. When storing the mower for extended
periods, disconnect the negative battery
cable. It is not necessary to remove
the battery.
2. All batteries discharge during storage.
Keep the exterior of the battery clean,
especially the top. A dirty battery will
discharge more rapidly.
3. The battery must be stored with a full
charge. A discharged battery can freeze
sooner than a charged battery. A fully
charged battery will store longer in cold
temperatures than hot.
4. Recharge the battery before returning to
service. Although the mower may start,
the engine charging system may not
fully recharge the battery.
Removing the Battery
1. Remove the flange lock nut (a) and
carriage screw (b) holding the battery
hold-down bracket (c) in place. See
Figure 4-5.
(a)
(b)
(c)
Figure 4-5
2. Remove the battery hold-down bracket.
3. Remove the hex cap screw and sems nut
securing the black negative battery lead
to the negative battery post (marked NEG).
Move the cable away from the negative
battery post.
4. Remove the hex cap screw and sems nut
securing the red positive battery lead to
the positive battery post (marked POS).
5. Carefully slide the battery out of
the mower.
6. Install the battery by repeating the
above steps in the reverse order.
Using the Transmission Bypass Rods
If for any reason the mower will not drive
or you wish to move the mower, the two
hydrostatic transmissions are equipped with
a bypass rod that will allow you to manually
move the mower short distances.
WARNING
Do not tow the mower, even with the bypass rod engaged.
Serious transmission damage will result from doing so.
1. Engage the transmission bypass by
pulling out on the bypass rod (a) and
then placing it down in the slot before
releasing. See Figure 4-6.
Pull Out
Down

Figure 4-6
2. To release the transmission bypass, pull
out and let the bypass rod slide back
into the frame.
Hydrostatic Transmission
The mower is equipped with dual integrated
hydrostatic pumps/transaxles that are sealed.
However, this model is equipped with a
transmission oil expansion reservoir. Under
normal operating conditions, the oil level in the
expansion reservoir does not need to be checked
and no additional oil is needed. If checking the
reservoir oil level, proceed as follows:
Note: See the Maintenance Schedule table for
transmission oil changing intervals.
WARNING
Check the oil level ONLY before starting the mower
when the transmission oil is fully cooled.
1. Clean the reservoir cap and the area
around the cap to prevent debris from
contaminating the transmission oil. See
Fi gu re 4 -7.
Figure 4-7
2. Turn the reservoir cap counter-clockwise
to remove, then check the oil level in
the reservoir. Oil should be visible at the
bottom of the cup, but the oil level must
NOT be above the “FULL COLD” line. See
Figure 4-7. DO NOT FILL THE RESERVOIR.

15Section 4 — Product care
3. If necessary to add oil because of some
type of leakage, use a quality 20W50 motor
oil and add only enough oil to bring the
level to the “FULL COLD” line. Reinstall the
cap and fully tighten.
Note: Prior to the initial operation of the
mower, the oil level in the reservoir may
be slightly higher than the maximum
due to air in the oil lines. Operation of
the mower will eventually purge the air
from the lines and the oil level will settle
to the maximum.
Mower Storage
If your mower is not going to be operated
for an extended period of time (30 days to
approximately six months), the mower should
be prepared for storage. Store the mower in a
dry and protected location. If stored outside,
cover the mower (including the tires) to protect
it from the elements. The procedures outlined
below should be performed whenever the
mower is placed in storage.
1. Change the engine oil and filter
following the instructions provided in
the Engine Operator’s Manual packed
with this manual.
WARNING
Never store the mower with fuel in the tank indoors or
in poorly ventilated enclosures, where fuel fumes may
reach an open flame, spark or pilot light as on a furnace,
water heater, clothes dryer, etc.
2. If storing the mower for 30 days or more:
a. To prevent gum deposits from
forming inside the engine’s
carburetor and causing possible
malfunction of the engine,
the fuel system must be either
completely emptied, or the
gasoline must be treated with a
stabilizer to prevent deterioration.
WARNING
Fuel left in the fuel tank deteriorates and will cause
serious starting problems.
b. Use a fuel stabilizer for storage
between 30 and 90 days:
• Read the product
manufacturer’s
instructions
and recommendations.
• Add to clean, fresh
gasoline the correct
amount of stabilizer
for the capacity
(approximately 3 gallons)
of the fuel system.
• Fill the fuel tank with
treated fuel and run the
engine for 2-3 minutes
to get stabilized fuel into
the carburetor.
c. Emptying the fuel system for
storage of more than 90 days:
• Prior to putting the
mower in storage,
monitor fuel
consumption with the
goal of running the fuel
tank empty.
• Run the engine until it
begins to stall. Use the
choke to keep the engine
running until all fuel
in the carburetor has
been exhausted.
• Referring to the Engine
Operator’s Manual,
drain the fuel from the
carburetor bowl.
3. Clean the engine and the entire
mower thoroughly.
4. Fully charge the battery, then disconnect
the negative cable at the battery to
prevent possible discharge. Recharge
the battery periodically when in storage.
Note: Remove the battery if exposed
to prolonged periods of sub-freezing
temperatures. Store in a cool, dry location
where temperatures are above freezing.
5. Lubricate all lubrication points.
Note: Using a pressure washer or garden
hose is not recommended for cleaning your
mower. It may cause damage to electrical
components, spindles, pulleys, bearings or
the engine. The use of water will result in
shortened life and reduce serviceability.
Removing the Mower from Storage
1. Check the engine oil.
2. Fully charge the battery and inflate the
tires to the recommended pressure.
3. Fill the fuel tank with clean, fresh gasoline.
4. Start the engine and allow to idle for
a few minutes to ensure engine is
operating properly.
5. Drive the mower without a load to
make certain all the mower systems are
functioning properly.
Adjustments
WARNING
Shut the engine off, remove the ignition key, and
engage the parking brake before making adjustments.
Protect your hands by using heavy gloves when
handling the blades.
Deck Leveling
WARNING
Shut the engine off, remove the ignition key, and
engage the parking brake before making adjustments.
Protect your hands by using heavy gloves when
handling the blades.
Leveling the Deck
Note: Check the mower’s tire pressure before
performing any deck leveling adjustments.
Refer to Tires for information regarding tire
pressure. Always level the deck side-to-side
before front-to-rear.
If the cutting deck appears to be mowing
unevenly, a side-to-side adjustment can be
performed. Adjust if necessary as follows:
1. Park the mower on a flat level surface.
2. Measure the distance from the outside
of the left blade tip to the ground and
the distance from the outside of the
right blade tip to the ground. Both
measurements taken should be equal. If
they are not, proceed to the next step.
3. There are four adjustment points on the
deck. Each of the deck lift adjustment
pins has an adjustment bolt (a). See
Figure 4-8. Raise or lower each side of
the deck using the four bolts (a) until the
side-to-side height is equal.
(a)
Figure 4-8
The front of the deck should be between 1/4-
3/8” lower than the rear of the deck. Adjust if
necessary as follows:
1. Raise or lower the front and/or rear of
the deck using the four adjustment bolts
(a) on the deck lift adjustment pins until
the front of the deck is 1/4-3/8” lower
than the rear of the deck. See Figure 4-8.
Adjusting the Gauge Wheels (If equipped)
WARNING
Keep hands and feet away from the discharge opening
of the cutting deck.
The front gauge wheels on the mower deck are
an anti-scalp feature, and should not ride on
the ground. The front gauge wheels should be
approximately 1/4-1/2” above the ground when the
deck is set in the desired height setting.
Using the deck lift handle, set the deck in the
desired height setting, then check the gauge wheel
distance from the ground below. If necessary adjust
the front gauge wheels as follows:
1. Visually check the distance between the
front gauge wheels and the ground. If
the gauge wheels are near or touching
the ground, they should be raised. If
more than 1/2” above the ground, they
should be lowered.
2. Remove the lock nut (a) securing one of
the front gauge wheel (b) to the deck.

Service
Charging the Battery
Test and, if necessary, recharge the battery after
the mower has been stored for a period of time.
• An AGM battery charger should be used.
Recommended charge rate is 1.1A/14.8V.
WARNING
Do NOT use an automotive charger.
• If your battery charger is automatic,
charge the battery until the charger
indicates that charging is complete. If
the charger is not automatic, charge for
no fewer than eight (8) hours.
Jump Starting
WARNING
Failure to use this starting procedure can cause
sparking, and the gases in the battery to explode.
1. Connect the end of one cable to the
disabled machine battery’s positive
terminal; then connect the other end
of that cable to the booster battery’s
positive terminal.
2. Connect one end of the other cable to
the booster battery’s negative terminal;
then connect the other end of that cable
to the frame of the disabled mower, as
far from the battery as possible.
3. Start the disabled mower following the
normal starting instructions previously
provided; then disconnect the jumper
cables in the exact reverse order of
their connection.
4. Have the mower’s electrical system
checked and repaired as soon as possible
to eliminate the need for jump starting.
Servicing Electrical System
Fuse
Always use the same capacity fuse for
replacement. If you have a recurring
problem with blown fuses, have the mower’s
electrical system checked by your authorized
service dealer.
Safety Interlock System & Switch
Operation Checks
After the engine has warmed up, shut off
the ignition and check the operation of the
safety switches.
• Make certain that the engine will not
start unless the key switch is turned on,
the transmission is in neutral and the
blade clutch is disengaged. Place the
neutral latch levers in the neutral lock
position. If the engine will start with the
transmission in any gear (not neutral),
immediately shut off the engine and
contact customer service. If the engine
will start with the blade clutch engaged,
immediately shut off the engine and
contact customer service.
To check operator presence controls:
1. With the neutral locks engaged, start
the engine and hold the left operator
presence control lever down against the
left handle and move the transmission
shift lever into first gear. Now take
your hand off the operator presence
control lever and the engine should die.
If it does not, immediately shut off the
engine and contact customer service.
2. Repeat this procedure using the right
operator presence control lever.
3. Shift the transmission into neutral,
restart the engine, hold one of the
operator presence controls down
against the handle and engage the
blade clutch. Now take your hand off
of the operator presence lever and
the engine should die. If it does not,
immediately shut off the engine and
disengage the blade.
Electric PTO Clutch
This clutch operates when the engine is running,
the operator is in the operator’s seat and the
PTO is engaged. This electric clutch is normally
a trouble free device. If a problem develops and
the blades do not turn, first check the 20 amp
fuse, then investigate the wiring harness and the
connections to the seat switch, the PTO switch
and the electric blade clutch. Then check the
PTO switch and the electric blade clutch. If the
PTO clutch is still not working properly, see an
authorized service dealer.
Deck Removal
WARNING
The muffler and any surrounding parts at the rear of the
mower may be extremely hot, and could cause serious
burns. Use extreme caution when near the muffler. Allow
the muffler to fully cool before removing the belt from the
PTO pulley.
Remove the mower deck from the mower
as follows:
1. Lower the deck to the ground.
2. Apply the parking brake. Remove
ignition key and the spark plug cap.
3. Using a 1/2” drive in the idler pulley

washer (e) at the blade (a) and remove
the blade.
5. To replace the blade reverse the above
process and tighten nut to 90-110 ft-lbs.
Note: When replacing the blade, be sure
to install the blade with the side of the
blade marked ‘‘Bottom’’ or “Grass Side”
(or with a part number stamped in it)
facing the ground when the mower is in
the operating position.
Note: Add a small amount of multi-
purpose grease to the bolt threads to
avoid corrosion and galvanic action.
WARNING
Never mow with dull blades. Blades that are bent should
be replaced. The cutting blades are sharp and can cause
severe injury. Wrap the cutting surface of the blade with
a rag to avoid injury.
Sharpening the Blades
1. Set the parking brake.
2. Clean any debris from the blades. Keep
blades sharp and free of build up at
all times.
3. To properly sharpen the cutting blades,
remove equal amounts of metal from
both ends of the blades along the cutting
edges, parallel to the trailing edge, at a
25°-30° angle. Always grind each cutting
blade edge equally to maintain proper
blade balance. See Figure 4-17.
Figure 4-17
WARNING
If a blade is bent or otherwise damaged, replace the blade
with a new one. Use only original equipment blades.
WARNING
A poorly balanced blade will cause excessive vibration,
may damage the machine and/or result in personal injury.
4. Test the blade’s balance using a blade
balancer. Grind metal from the heavy
side until it balances evenly.
Note: When replacing the blade, be sure
to install the blade with the side of the
blade marked ‘‘Bottom’’ or “Grass Side”
(or with a part number stamped in it)
facing the ground when the mower is in
the operating position.
WARNING
