Data indicates that operators, age 60 years and above, are

28.
involved in a large percentage of riding mower-related
injuries. These operators should evaluate their ability
to operate the riding mower safely enough to protect
themselves and others from serious injury.

If situations occur which are not covered in this manual, use

29.
care and good judgment. Contact your customer service
representative for assistance.

Slope Operation

Slopes are a major factor related to loss of control and tip-over
accidents which can result in severe injury or death. All slopes
require extra caution. If you cannot back up the slope or if you
feel uneasy on it, 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 degrees as
shown on the slope gauge, do not operate this machine on that
area or serious injury could result.

Do:

Mow across slopes, not up and down. Exercise extreme

1.
caution when changing direction on slopes.

Watch for holes, ruts, bumps, rocks, or other hidden

2.
objects. Uneven terrain could overturn the machine. Tall
grass can hide obstacles.

Use slow speed. Choose a low enough speed so that you

3.
will not have to stop while on the slope. Avoid starting
or stopping on a slope. If the tires are unable to maintain
traction, disengage the blades and proceed slowly and
carefully straight down the slope.

Follow the manufacturer’s recommendations for wheel

4.
weights or counterweights to improve stability.

Use extra care with grass catchers or other attachments.

5.
These can change the stability of the machine.

Keep all movement on the slopes slow and gradual. Do

6.
not make sudden changes in speed or direction. Rapid
acceleration or deceleration could cause the front of the
machine to lift and rapidly flip over backwards, which
could cause serious injury.

Do Not:

Do not turn on slopes unless necessary; then turn slowly

1.
uphill and use extra care while turning.

Do not mow near drop-offs, ditches or embankments. The

2.
mower could suddenly turn over if a wheel is over the edge
of a cliff, ditch, or if an edge caves in.

Do not try to stabilize the machine by putting your foot on

3.
the ground.

Do not use a grass catcher on steep slopes.

4.
Do not mow on wet grass. Reduced traction could cause

5.
sliding.

Do not tow heavy pull behind attachments (e.g. loaded

6.
dump cart, lawn roller, etc.) on slopes greater than 5
degrees. When going down hill, the extra weight tends to
push the tractor and may cause you to loose control (e.g.
tractor may speed up, braking and steering ability are
reduced, attachment may jack-knife and cause tractor to
overturn).

4 sectiOn 2 — iMpOrtant safe OperatiOn practices

Children

Tragic accidents can occur if the operator is not alert to the

1.
presence of children. Children are often attracted to the
machine and the mowing activity. They do not understand
the dangers. Never assume that children will remain where
you last saw them.

Keep children out of the mowing area and in

a.

watchful care of a responsible adult other than the
operator.

Be alert and turn machine off if a child enters the

b.

area.
To avoid back-over accidents, always look behind

c.

and down for small children.
Never carry children, even with the blade(s) shut off.

d.

They may fall off and be seriously injured or interfere
with safe machine operation.

Use extreme care when approaching blind corners,

e.

doorways, shrubs, trees or other objects that may
block your vision of a child who may run into the
path of the machine.

Keep children away from hot or running engines.

f.

They can suffer burns from a hot muffler.
Remove key when machine is unattended to

g.

prevent unauthorized operation.

Never allow children under 14 years of age to operate this

2.
machine. Children 14 and over should read and understand
the instructions and safe operation practices in this manual
and on the machine and should be trained and supervised
by an adult.

Towing

Tow only with a machine that has a hitch designed for

1.
towing. Do not attach towed equipment except at the
hitch point.

Follow the manufacturers recommendation for weight

2.
limits for towed equipment and towing on slopes.

Never allow children or others in or on towed equipment.

3.
On slopes, the weight of the towed equipment may cause

4.
loss of traction and loss of control.

Travel slowly and allow extra distance to stop.

5.
Do not shift to neutral and coast downhill.

6.

Service

Safe Handling of Gasoline:

To avoid personal injury or property damage use extreme

1.
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.

Use only an approved gasoline container.

a.

Never fill containers inside a vehicle or on a truck

b.

or trailer bed with a plastic liner. Always place
containers on the ground away from your vehicle
before filling.

When practical, remove gas-powered equipment

c.

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.

Keep the nozzle in contact with the rim of the fuel

d.

tank or container opening at all times until fueling is
complete. Do not use a nozzle lock-open device.

Extinguish all cigarettes, cigars, pipes and other

e.

sources of ignition.
Never fuel machine indoors.

f.

Never remove gas cap or add fuel while the engine

g.

is hot or running. Allow engine to cool at least two
minutes before refueling.

Never over fill fuel tank. Fill tank to no more than ½

h.

inch below bottom of filler neck to allow space for
fuel expansion.

Replace gasoline cap and tighten securely.

i.

If gasoline is spilled, wipe it off the engine and

j.

equipment. Move machine to another area. Wait 5
minutes before starting the engine.

To reduce fire hazards, keep machine free of grass,

k.

leaves, or other debris build-up. Clean up oil or fuel
spillage and remove any fuel soaked debris.

Never store the machine or fuel container inside

l.

where there is an open flame, spark or pilot light
as on a water heater, space heater, furnace, clothes
dryer or other gas appliances.

Allow a machine to cool at least five minutes before

m.

storing.

General Service

Never run an engine indoors or in a poorly ventilated area.

1.
Engine exhaust contains carbon monoxide, an odorless,
and deadly gas.

Before cleaning, repairing, or inspecting, make certain the

2.
blade(s) and all moving parts have stopped. Disconnect the
spark plug wire and ground against the engine to prevent
unintended starting.

Periodically check to make sure the blades come to

3.
complete stop within approximately (5) five seconds after
operating the blade disengagement control. If the blades
do not stop within the this time frame, your machine
should be serviced professionally by an authorized Cub
Cadet Dealer.

Regularly check the safety interlock system for proper

4.
function, as described later in this manual. If the safety
interlock system does not function properly, have your
machine serviced professionally by an authorized Cub
Cadet Dealer.

5sectiOn 2 — iMpOrtant safe OperatiOn practices

5.

Check the blade(s) and engine mounting bolts at frequent
intervals for proper tightness. Also, visually inspect blade(s)
for damage (e.g., excessive wear, bent, cracked). Replace
the blade(s) with the original equipment manufacturer’s
(O.E.M.) blade(s) only, listed in this manual. “Use of parts
which do not meet the original equipment specifications
may lead to improper performance and compromise
safety!”

6.

Mower blades are sharp. Wrap the blade or wear gloves,
and use extra caution when servicing them.

7.

Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.

8.

Never tamper with the safety interlock system or other
safety devices. Check their proper operation regularly.

9.

After striking a foreign object, stop the engine, disconnect
the spark plug wire(s) and ground against the engine.
Thoroughly inspect the machine for any damage. Repair
the damage before starting and operating.

10.

Never attempt to make adjustments or repairs to the
machine while the engine is running.

11.

Grass catcher components and the discharge cover are
subject to wear and damage which could expose moving
parts or allow objects to be thrown. For safety protection,
frequently check components and replace immediately
with original equipment manufacturer’s (O.E.M.) parts only,
listed in this manual. “Use of parts which do not meet the
original equipment specifications may lead to improper
performance and compromise safety!”

12.

Do not change the engine governor settings or over-speed
the engine. The governor controls the maximum safe
operating speed of the engine.

13.

Maintain or replace safety and instruction labels, as
necessary.

14.

Observe proper disposal laws and regulations for gas, oil,
etc. to protect the environment.

General Safety

RECEIVE INSTRUCTION - Entirely read this operator’s

•
manual. Learn to operate this machine SAFELY. Do
not risk INJURY or DEATH. Allow only those who have
become competent in its usage to operate this tractor.

Before starting the engine or beginning operation,

•
be familiar with the controls. The operator should be
in the operator’s seat. The PTO switch must be in the
disengaged position, the parking brake engaged,
and the RH and LH drive control levers moved fully
outward in the neutral position.

Keep all shields in place. Keep away from moving parts.

•
NO RIDERS! Keep all people and pets a safe distance

•
away. Look behind and down to both sides of the
tractor before and while backing up.

DO NOT direct the mower discharge at people.

•
Avoid slopes where possible. Never operate on slopes

•
greater than 15°. Slopes with a greater incline present
dangerous operating conditions. Tractors can be rolled
over.

Before leaving the operator’s seat: Shut off the PTO,

•
move the RH and LH drive control levers fully outward
in the neutral position, engage the parking brake, shut
off the engine and remove the ignition key. Wait for all
movement to stop before servicing or cleaning.

Operate the drive control levers smoothly and avoid

•
any sudden movements of the levers when starting
and stopping. Keep a firm grip on the control levers; do
not allow the levers to return to neutral on their own.

Be careful when operating near roadways. Stop the

•
tractor motion and wait for vehicles to pass before
operating along the road.

Do not operate the tractor with the mower deck

•
removed. Removal of the deck will change the balance
of the tractor, and could contribute to a tractor rollover.

Avoid operation on traction surfaces that are unstable;

•
use extreme caution if the surface is slippery.

Slow down before turning and come to a complete

•
stop before any zero turn maneuver.

Do not stop the tractor or park the tractor over

•
combustible materials such as dry grass, leaves, debris,
etc.

Do not fill the fuel tank when the engine is running

•
or while the engine is hot. Allow the engine several
minutes to cool before refueling. Tighten the fuel cap
securely.

Before Operating Your Tractor

Before you operate the tractor, study this manual

•
carefully to familiarize yourself with the operation of all
the instruments and controls. It has been prepared to
help you operate and maintain your tractor efficiently.

This engine is certified to operate only on clean, fresh,

•
unleaded regular gasoline. For best results, fill the fuel
tank with only clean, fresh, unleaded gasoline with a
pump sticker octane rating of 87 or higher.

Unleaded gasoline is recommended because it leaves

•
less combustion chamber deposits and reduces
harmful exhaust emissions. Leaded gasoline is not
recommended and must not be used where exhaust
emissions are regulated.

NOTE: Purchase gasoline in small quantities. Do not use
gasoline left over from the previous season, to minimize gum
deposits in the fuel system.

Gasohol (up to 10% ethyl alcohol, 90% unleaded

•
gasoline by volume) is an approved fuel. Other
gasoline/alcohol blends are not approved.

Methyl Tertiary Butyl Ether (MTBE) and unleaded

•
gasoline blends (up to a maximum of 15% MTBE by
volume) are approved fuels. Other gasoline/ether
blends are not approved.

Check the engine oil level.

•
Clean the air cleaner element if necessary. Refer to

•
engine manual.

Check the tire inflation pressures.

•
Adjust the seat for operator’s maximum comfort,

•
visibility and for maintaining complete control of the
tractor.

Safety Interlock System

This tractor is equipped with a safety interlock system
for the protection of the operator. If the interlock system
should ever malfunction, do not operate the tractor.
Contact your authorized Troy-Bilt Service Dealer.

The safety interlock system prevents the engine

•
from cranking or starting unless the RH and LH drive
control levers are moved fully outward in the neutral
position, the parking brake is engaged, and the PTO is
disengaged.

To avoid sudden movement when disengaging the

•
parking brake, the safety interlock system will shut
off the engine if the RH and/or LH drive control levers
are moved to a position other than the fully out in the
neutral position when the parking brake is engaged.

Engage the parking brake. Refer to Figure 5-1.
Make certain the PTO switch is in the disengaged

(down) position. Refer to Figure 5-1.
Pull the choke control knob upward to the full choke

position. NOTE: If the engine is warmed up, it may not be

necessary to choke the engine.

Move the throttle control to midway between its SLOW
and FAST positions.

Turn the ignition key clockwise to the “START” position

•
and release it as soon as the engine starts; however,
do not crank the engine continuously for more than 5
seconds at a time. If the engine does not start within
this time, turn the key to “OFF” and wait at least 15
seconds to allow the engine’s starter motor to cool.
Try again after waiting. If after a few attempts the
engine fails to start, do not keep trying to start it with
the choke closed as this will cause flooding and make
starting more difficult.

As the engine warms up, gradually push the choke

•
knob downward to open the choke. Do not use the
choke to enrich the fuel mixture, except as necessary to
start the engine.

Allow the engine to run for a few minutes at mid

•

Observe the hour meter / indicator panel. If the

•
battery indicator light or oil pressure light come
on, immediately stop the engine. Have the tractor
inspected by your Troy-Bilt Service dealer.

Cold Weather Starting

When starting the engine at temperatures near or below
freezing, ensure the correct viscosity motor oil is used
in the engine and the battery is fully charged. Start the
engine as follows:

Be sure the battery is in good condition. A warm

•
battery has much more starting capacity than a cold
battery.

Use fresh winter grade fuel. Winter grade gasoline

•
has higher volatility to improve starting. Do not use
gasoline left over from summer.

Follow the previous instruction for STARTING THE

•
ENGINE.

Using Jumper Cables To Start Engine

WARNING!: Batteries contain sulfuric acid and

produce explosive gasses. Make certain the
area is well ventilated, wear gloves and eye
protection, and avoid sparks or flames near
the battery.

If the battery charge is not sufficient to crank the engine,
recharge the battery. If a battery charger is unavailable
and the tractor must be started, the aid of a booster
battery will be necessary. Connect the booster battery as
follows:

Connect the end of one cable to the disabled tractor

•
battery’s positive terminal; then connect the other end
of that cable to the booster battery’s positive terminal.

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 tractor, as far
from the battery as possible.

Practice Operation (Initial Use)

Operating a zero-turn tractor is not like operating a
conventional type riding tractor. Although and because a
zero turn tractor is more maneuverable, getting used to
operating the control levers takes some practice.

We strongly recommend that you locate a reasonably
large, level and open “practice area” where there are no
obstructions, pedestrians, or animals. You should practice
operating the tractor for a minimum of 30 minutes.

Carefully move (or have moved) the tractor to the practice
area. When performing the practice session, the PTO
should not be engaged. While practicing, operate the
tractor at approximately 1/2-3/4 throttle and at less than
full speed in both forward and reverse.

Carefully practice maneuvering the tractor using the
instructions in the following section “Driving the Tractor.”
Practice until you are confident that you can safely operate
the tractor.

Figure 5-2

Move the throttle control lever forward to the full

•

throttle position (3500-3600 RPM). NOTE: Although the

tractor’s engine is designed to run at full throttle, when
performing a practice session the tractor must be operated
at less than full throttle (approximately 2500-3000 RPM).
This only applies to practice.

WARNING!: Always maintain a firm grip on
the control levers. DO NOT release the control
levers to slow or stop the tractor; move levers
to neutral position using your hands.

To drive the tractor, firmly grasp the respective drive

•
control levers with your right and left hands and
proceed as instructed in the following sub section.

Driving the Tractor Forward

WARNING!: Keep all movement of the drive

control levers slow and smooth. Abrupt
movement of the control levers can affect the
stability of the tractor and could cause the
tractor to flip over, which may result in serious

injury or death to the operator.

Slowly and evenly move both drive control levers

•
forward. The tractor will start to move forward. See
Figure 5-3.

Driving the Tractor

Adjust the operator’s seat to the most comfortable

•
position that allows you to operate the controls. See
seat adjustment in the ADJUSTMENTS section.

Release the parking brake.

•
Move the RH and LH drive control levers inward in the

•
neutral position. Refer to Figure 5-2.

NOTE: If the control levers are not even in the neutral position,
refer to Maintenance & Adjustments for instructions to
adjust the levers so that they are even.

WARNING!: Avoid sudden starts, excessive

speed and sudden stops.

Turning the Tractor While Driving Forward

WARNING!: When reversing the direction of

travel, we recommend performing gradual ‘U’
turns where possible. Sharper turns increase
the possibility of turf defacement, and could
affect control of the tractor. ALWAYS slow the
tractor before making sharp turns.

To turn the tractor while driving forward, move the control
levers as necessary so that one lever is rearward of the
other. The tractor will turn in the direction of the rearward
control lever.

To turn to the left, move the left drive control lever

•
rearward of the right lever. See Figure 5-4.

Driving the Tractor In Reverse

WARNING!: Always look behind and down

on both sides of the tractor before backing
up. Always look behind while traveling in the
reverse direction.

Slowly and evenly move both drive control levers

•
rearward. The tractor will start to move in the reverse
direction. See Figure 5-6.

Driving On Slopes

Refer to the SLOPE GAUGE on page 7 to help determine
slopes where you may not operate safely.

WARNING!: Do not operate on inclines with
a slope in excess of 15 degrees (a rise of
approximately 2-1/2 feet every 10 feet). The
tractor could overturn and cause serious injury.

Always drive across slopes, never up and down. Control

•
the speed and direction of the tractor using primarily
the control lever on the downhill side of the tractor,
with the uphill control lever remaining essentially in a
fixed position.

Avoid turning downhill if possible. Start at the bottom

•
of a slope and work upward. Always slow down before
turning.

Use extra care and go slowly when turning downhill.

•

17sectiOn 5 — OperatiOn

Operating The PTO

Operate the PTO clutch as follows:

Move the throttle control lever to approximately the

•
mid throttle position.

Pull the PTO switch upward to the “ENGAGED” position.

•
Advance the throttle lever to the operating speed (full

•
engine speed).

The operator must remain in the tractor seat at all

•
times. If the operator should leave the seat without
turning off the power take-off switch, the tractor’s
engine will shut off.

The PTO clutch cannot be operated when the tractor is

•
driving in the reverse direction. The PTO will disengage
when both drive control levers are moved to the
reverse position, and will re-engage when one (or
both) control lever(s) is moved to the neutral or forward
position.

Using the Mower Deck

WARNING!: Make certain the area to be

mowed is free of debris, sticks, stones, wire
or other objects that can be thrown by the
rotating blades.

IMPORTANT: Do not engage the mower deck when lowered in

grass. Premature wear and possible failure of the ‘V” belt and
PTO clutch will result. Fully raise the deck or move to a non
grassy area before engaging the mower deck.

Mow across slopes, not up and down. If mowing a

•
slope, start at bottom and work upward to ensure turns
are made uphill.

On the first pass pick a point on the opposite side of

•
the area to be mowed.

Engage the PTO clutch using the PTO switch and move

•
the throttle control to the fast position.

Lower the mower deck to the desired height setting

•
using the lift handle.

Slowly and evenly push the RH and LH drive control

•
levers forward to move the tractor forward, and keep
the tractor headed directly toward the alignment point.

NOTE: The speed of the tractor will affect the quality of

the mower cut. Mowing at full speed will adversely affect
the cut quality. Control the ground speed with the control
levers.

When approaching the other end of the strip, slow

•
down or stop before turning. A U-turn is recommended
unless a pivot or zero turn is required.

Align the mower with an edge of the mowed strip and

•
overlap approximately 3 inches.

Direct the tractor on each subsequent strip to align

•
with a previously cut strip.

To prevent rutting or grooving of the turf, if possible,

•
change the direction that the strips are mowed by
approximately 45° for the next and each subsequent
mowing.

WARNING!: Be careful when crossing gravel
paths or driveways. Disengage the PTO and
raise the deck to the highest position before
crossing.

IMPORTANT: When stopping the tractor for any reason while

on a grass surface, always:

Place the shift lever in neutral,

•
Engage the parking brake,

•
Shut engine off and remove the key.

•
Doing so will minimize the possibility of having your

•
lawn ‘‘browned’’ by hot exhaust from your tractor’s
running engine.

Checking the Safety Interlock Circuits

Periodically check the safety interlock circuits to ensure
they are working properly. If a safety circuit is not working
as designed, contact you Troy-Bilt Service dealer to have
the tractor inspected. DO NOT operate the tractor if any
safety circuit is not functioning properly. To check the
safety circuits, proceed as follows:

•
position and engage the parking brake. Start the
engine and move one of the drive control levers from
the fully outward neutral position. The engine should
stop running. Repeat the procedure with the opposite
control lever.

Move both control levers fully outward in the neutral

•
position and disengage the parking brake; then lift
upward from the operator’s seat. The engine should
stop.

With both control levers fully outward in the neutral

•
position and the parking brake engaged, engage the
PTO. Lift upward from the operator’s seat; the engine
should stop.

Start the tractor, disengage the parking brake, and

•
move the control levers inward to the neutral operating
position. Engage the PTO and move both control lever
slowly into the slow reverse position; the PTO should

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. See the tire side wall for proper
inflation pressures. 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 a qualified tire mechanic inspect
and service the tire.

Lubrication

Using a pressure lubricating gun, lubricate the front

•
castor wheel axles and the front pivot axle with a No.2
lithium EP grease after every 10 hours of service.

Periodically lubricate all other pivot points with a

•
quality lubricating oil.

Using the Deck Wash System

WARNING!: When using the deck wash
system, never engage the deck from any

position other than the operator’s seat of the
tractor. Do not use an assistant or engage
deck in the presence of any bystanders.

Attach the nozzle adapter to a standard garden hose

•
connected to a water supply.

Move the tractor to an area within reach of the hose

•
where the dispersal of wet grass clippings is not
objectionable to you. Disengage the PTO, engage the
parking brake, and stop the engine.

Pull back the lock collar of the nozzle adapter and push

•
the adapter onto one of the deck wash nozzles at either
end of the mower deck. Release the lock collar to lock
the adapter on the nozzle. See Figure 6-2.

Figure 6-2

Turn on the water supply.

•
From the tractor operator’s seat, start the engine and

•
engage the PTO. Allow to run as needed. Disengage
the PTO and stop the engine.

Turn off the water supply.

•
Pull back the lock collar of the nozzle adapter to

•
disconnect the adapter from the nozzle.

Repeat the previous steps to clean the deck using the

•
nozzle at the other end of the deck.

Cleaning the Spindle Pulleys

Once a month remove the belt covers to remove any
accumulation of grass clippings from around the spindle
pulleys and V-belt. Clean more often when mowing tall,
dry grass.

Using the Transmission Bypass Rods

If for any reason the tractor will not drive or you wish to
move the tractor, the two hydrostatic transmissions are
equipped with a bypass rod that will allow you to manually
move the tractor short distances.

20 sectiOn 6— Maintenance & adjustMents

WARNING! : Do not tow the tractor, even with

the bypass rod engaged. Serious transmission
damage will result from doing so.

From just in front of the two rear tires, locate the

•
transmission bypass rods. Refer to Figure 6-3.

Pull one rod toward the front of the tractor until the

•
flange on the rod is forward of the keyhole slot in the
frame assembly.

Lower the bypass rod into the keyhole slot and release

•
so the rod flange is against the front of the frame
bracket.

Tractor Storage

If your tractor is not going to be operated for an extended
period of time (thirty days to approximately six months),
the tractor should be prepared for storage. Store the
tractor in a dry and protected location. If stored outside,
cover the tractor (including the tires) to protect it from
the elements. The procedures outlined below should be
performed whenever the tractor is placed in storage.

Change the engine oil and filter following the

1.
instructions provided in the engine manual packed
with this manual.

WARNING!: Never store the tractor 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.

If storing the tractor for 30 days or more:

2.
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.

Figure 6-3

Repeat the above procedure to engage the other

•
bypass rod on the other side of the tractor.

After moving the tractor, disengage both bypass rods.

•
Lift the rod and guide the flange of the rod back
through the larger circular opening of the keyhole,
then release the rod.

IMPORTANT: The tractor will not drive with the bypass rods
in the engage position.

Battery Storage

When storing the tractor for extended periods,

•
disconnect the negative battery cable. It is not
necessary to remove the battery.

All batteries discharge during storage. Keep the

•
exterior of the battery clean, especially the top. A dirty
battery will discharge more rapidly.

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.

Recharge the battery before returning to service.

•
Although the tractor may start, the engine charging
system may not fully recharge the battery.

Using a fuel stabilizer:

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.

Emptying the fuel system:

Prior to putting the tractor 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 manual, drain the fuel from the

•
carburetor bowl.

Clean the engine and the entire tractor thoroughly.

3.
Fully charge the battery, then disconnect the negative

4.
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.
