This symbol is used to call your atten-
tion to instructions concerning your
personal safety. Be sure to observe and
follow these instructions.
Disengage all clutches and shift into neutral before
starting the engine.
To avoid injury, disengage power to any attachments and stop engine before leaving operator's
seat or making any repairs or adjustments.
Know the controls and how to stop quickly.
READ THE OPERATOR'S MANUAL.
To avoid an accident or injury, do not allow
children or adults to operate the equipment without proper instructions. Keep children, pets, and
bystanders a safe distance away.
Clear work area of objects which might be picked
up and thrown.
Use care when pulling loads or using heavy
equipment. Use only approved hitch points, and
limit loads to those you can safely carry. Use
counterweight or wheel weights when suggested in
Operator's Manual.
Handle gasoline with care -it is highly flammable:
-A. Use approved gasoline container. B. Never
remove the fuel tank cap or fill the fuel tank when
the engine is running, is hot, or indoors. Also, do
not smoke when working around flammable fuel.
Wipe up spilled gasoline. C. Replace gasoline cap
securely.
During operation do not run the engine in confined
area such as storage building any longer than is
necessary for immediate moving of the tractor
outside into the air.
Keep machine in good operating condition and
keep safety devices in place. Use guards or shields
as instructed in Operator's Manual.
Disengage power to any attachment when transporting or not in use.
To prevent an accident, always disengage the
power take-off, shift transmission into neutral, set
the parking brake, stop the engine, and remove
ignition key when leaving the machine unattended.
Reduce speed on slopes and in sharp turns to
prevent tipping or loss of control.
Stay alert for holes in terrain and other hidden
hazards.
Before backing the tractor, always look for obstacles or bystanders in the area where the tractor
will move.
To avoid the possibility of an upset, always engage
the clutch slowly, especially on steep slopes. Avoid
quick starts and stops.
NO RIDERS! This machine is designed to safely
carryon Iy the operator. Do not carry passengers or
give rides as serious injury could result.
It is recommended that the machine be stopped
and inspected for damage after striking a foreign
object and that any damage be repaired before
restarting and operating the machine.
Always turn ignition "OFF", depress the brake
pedal, and set the brake pedal lock before working
on the machine. Disengage all implements and shift
the transmission into neutral.
REMEMBER -A careful operator is the best
insurance against an accident.
Avoid Overturns -Back the tractor up the steepest
portion of the hill to be mowed! If the tractor
cannot do this, the hi II is too steep for safe
operation. When mowing hills, cut down the face
of the hill rather than across to avoid side tipping.
Also, avoid sudden starts, stops, and turns,
especially on steep slopes to avoid an upset.
Do not allow anyone in the area parallel to the
discharge opening while mowing. Although the
area has been supposedly cleared of foreign objects, small objects may have been overlooked and
may be discharged by the mower causing serious
injury.

OPERATING THE ENGINE
COLD WEATHER STARTING -Continued
Press the clutch-brake pedal all the way downand
be sure the power take-off switch is in the off
position. The safety interlocks will prevent starting
unless this is done.
Move the key switch into the start position and
hold until the engine starts. As soon as the engine
starts, slowly push the choke in part way.
CAUTION! During operation do not run
the engine in confined area such as
storage building any longer than is
necessary for immediate moving of the tractor
outside into the air.
NOTE: In cold weather the starting motor may
disengage prematurely. This is caused by the engine
firing once but failing to continue running. If this
happens several times, the engine will be flooded
and it will be necessary to start as described in Step5.
5. Leave the throttle in the slow position but push
the choke in all the way; then turn the ignition key
to the start position and slowly pull the choke out
to the position which will cause the engine to start
and continue running. If the engine falters after
shifting into drive, pull the choke out part way
until the engine runs smoothly, then gradually
push the choke back in as the engine warms.
FUEL SYSTEM
This engine is designed to operate on leaded
gasoline with a 93 minimum octane rating or on
unleaded gasoline with a 91 minimum octane
rating (Research Method).
The use of unleaded gasoline will increase spark
plug and valve life, maintain engine performance
longer, and reduce rust and corrosion of the engine
while stored.
The fuel tank filler cap has an air vent. Keep the
vent open at all times to assure proper flow of thefuel.
A CAUTION! Do not remove the fuel tank
cap or fill the fuel tank when the engine
is running, hot, or when near an openflame.
Do not smoke when working around
flammable fuel, as the air around the tractor is
mixed with a highly explosive vapor.
FUEL SHUT-OFF VALVE
Be sure the shut-off valve under the fuel tank is
open. Pullout the needle stem (shut-off valve)
until the seat on the stem is tight against the stop
to prevent leakage or seepage when the valve is in
its full-open position.
CARBURETOR ADJUSTMENTS
NOTE: Air cleaner has been removed from
illustrations in order to show carburetor.
A CAUTION! To avoid injury or an
accident, be sure the brake pedal is in
the locked position, transmission is in
neutral, and the mower is disengaged before
adjusting the carburetor.
The carburetor is adjusted at the factory and under
normal operating conditions it will not require
readjusting. However, if the engine does not
operate properly, installation of a new air cleaner is
recommended.
NOTE: To prevent possible damage to the
carburetor needles, be very careful closing the
carburetor needles before basic adjustments are
made. I mproper adjustment of the carburetor may
result in engine damage.

CARBURETOR ADJUSTMENTS -Continued If the engine misses and backfires under load, the
high speed mixture is too lean. The high speed
adjustment screw must be turned counterclockwise
1/8 turn at a time until the condition is corrected.
If the engine shows a sooty exhaust and is sluggish
under load, the high speed mixture is too rich. The
high speed adjustment screw must be turned
clockwise 1/8 turn at a time until the condition is
corrected.
Adjusting the Idle Adjustment Screw
After the high speed adjustment screw is adjusted,
it may be necessary to readjust the idle adjustment

turning it clockwise; then open it one turn. Start
the engine and operate it at fast idling speed
(without any load) until thoroughly warm.
While the engine is running at fast idle speed, it is
advisable to screw in the throttle stop screw a few
turns to keep the engine from stopping when the
throttle lever is moved to the fully retarded
"SLOW" position. The engine will then be idling at
a fairly high speed and the throttle stop screw can
be backed out a little at a time until the desired
idle speed is obtained (1800 RPM).
Turn the high speed adjustment screw counterclockwise approximately two turns from the closed
position and start the engine.
If the engine misses or rolls while backing out the
throttle stop screw, the idle adjustment screw may
be adjusted in or out until the engine operates

then recheck the idle adjustment. A slight adjust-
ment in or out will give the smoothest idle.
After the engine has reached normal operating
temperature, place the throttle lever in the fast
position and turn the high speed adjustment screw
clockwise to the leanest mixture that will allow
satisfactory acceleration and steady governor
operation. Then, turn counterclockwise to the
richest mixture that allows satisfactory operation.

ELECTRICAL SYSTEM
FUSE. Continued
NOTE: There are two fuses adjacent to the lighting
switch on the tractor pedestal (left side). The lower
fuse is for the lights; the upper fuse is for the
electric clutch.
install a new fuse, press in on the fuse housing
cap and turn counterclockwise to remove it from
the fuse housing. Remove the old fuse and replace
it with a new one. Then reassemble the cap to the
housing.
Before working on any part of the electrical
system, disconnect the battery ground cable at the
battery negative (-j terminal. Do not reconnect this
cable until all work has been completed. This will
prevent shorting and damage to any of the elec-
trical units. Examine the electrcial cables occa-
sionally to be sure they are not being frayed by
contact with adjacent parts.
When replacing a battery, make certain the ground
cable is connected to the negative (-) terminal on
the battery. Be su re the rubber boot is properly
positioned over the positive (+) terminal on the
battery. NOTE: Both cables must be assembled
with the nuts to the inside of the terminals to
prevent shorting against fender well.
Cleaning and Servicing the Battery
The electrolyte (acid and water) in each cell should
be at ring level at all times to prevent battery
failure. When the electrolyte is below this level,
add pure, distilled water.
Acid or electrolyte should never be added except
by a skilled battery man. Under no circumstances
add any special battery "dopes", solutions or
powders.
CAUTION! If the tractor is to be tipped
up or on its side remove the batteries to
avoid spilling the electroyte. Battery
electrolyte is poisonous and can be injurious to
eyes, skin, and clothing. If electrolyte is spilled,
flush immediately with water, followed by a
solution of one part baking soda to four partswater.
Connecting Booster Batteries
When required, a booster 12-volt battery may be
connected in parallel with the 12-volt system on
I nternational Cub Cadet Tractors.
CAUTION! Gas discharged by batteries
is explosive. Avoid sparks near the
batteries.
Occasionally remove the battery cables and
brighten the terminal contact surfaces with wire
wool, and reassemble them. Apply a light coat of
vaseline or chassis lubricant. Be sure the terminals
are clamped tightely and that the battery is
fastened securely in the battery box. Replace
unserviceable cable. Keep the vent holes in the
battery filler caps open.
Keeping the battery fully charged not only adds to
its life but makes it available for instant use when
needed.
Level
Check the battery at least once a month for
electrolyte level.
NOTE: All circuits must be turned "off". Electrical system is NEGATIVE (-) grounded only.
Reversed polarity will result in permanent damage
to components of the electricat system.
The first jumper cable must connect the positive
(+) terminal of the booster battery and the positive
terminal of the battery on the tractor.
The second jumper cable must first be connected
to the negative (-) terminal of the booster battery;
and then to a point on the frame of the tractor,
away from the battery, having a good ground, so
no spark occurs near the battery.
For dependable battery service, see your I nter-

OPERATING PRESSURE FOR TIRES
6-12 rear tires are standard equipment on the
International Cub Cadet 1000 Tractor.
23 x 8.50-12 high floatation tires are standard
equipment on the I nternational Cub Cadet 1200,
1250, and 1450 Tractors. They are also ayailable as
optiohal equipment when ordered for the
International Cub Cadet 1000 Tractor.
23 x 10.5-12 tires are standard on the International
Cub Cadet 1650 Tractor.
The high floatation tires provide maximum
mobility in sand, snow, and soft soil conditions.
The reduced ground pressure and low inflation
provides maximum protection for turf, soil and
crops.
CARE OF TIRES
Avoid stumps, stones, deep ruts, curbs, and other
hazards. Cuts in tires should te repaired immediately as neglect decreases the tire life.
I nflate the front and rear tires for normal or heavy
load operations as shown in the following table.

REAR WHEEL WEIGHTS
Rear wheel weights increase traction and reduce
wheel slippage. The weights weight approximately
26 pounds each. They are attached to each rear
wheel with two bolts, lock washers, and hex nuts.

MOUNTING TIRES ON THE RIM
Keep tires free from oil and grease as both destroy
rubber.
After using the tractor for spraying use water to
remove any chemicals that may be on the tires.
INFLATION
Keep the pneumatic tires properly inflated. Overinflation will cause operator discomfort. Underinflation will cause short tire life.
Always see that the tire valve caps are in place and
tightened securely to prevent loss of air and
protect the valve core and stem.
After mounting a new or old tire on the rim,
inflate it to 20 pounds pressure to seat the tire
bead on the rim flange. Then deflate the tire to the
correct operating pressure.
TIRE CHAINS
Tire chains will provide additional traction for wet
ground conditions, when plowing snow, or pulling
heavy loads. Rear wheel weights are recommended
when using chains.
OVERLOADING
Do not overload the tractor tires by mounting
equipment on the tractor which exceeds the load
capacity of the size of the tires on the tractor.

ground as the front wheel hubs. Measure the
distance between the marks "A", then rotate the
tires so that the marks are toward the rear of the
tractor, the same height from the grou nd as they
were in front. The dimension should be approxi-

CAUTION! To avoid injury or possible
accident, be very careful and take nec-
essary precautions when raising tractor
off the ground.
When your tractor is not to be used for some time,
it should be stored in a dry and protected place.
Leaving your tractor out-doors, exposed to the
elements materially shortens its life.
To adjust the brake, loosen jam nut "B". Next,
tighten the brake lever adjusting screw "c" until
finger tight (8 -1 a-inch pounds). Tighten jam nut
"B" while holding the adjusting screw.
If the brake drags after tightening jam nut "B",
loosen the jam nut and back off adjusting screw
"c" slightly and retighten jam nut "B". Recheck
brake adjustment and insure proper brake opera-
tion before operating the tractor.
Remember -A careful oper-
ator is the best insurance against an
accident.
Drain the fuel tank and run the engine until the
fuel is exhausted from the fuel system.
Follow the procedure outlined below when storing
a tractor for an extended period of time.
NOTE: Gum will eventually form in the fuel tank,

STORING THE TRACTOR
REMOVING FROM STORAGE
1. Fill the fuel tank and be sure the grade of oil in
the crankcase is according to the temperature range
in the "lubrication Table".
2. Install a fully charged battery and properly
connect.
A CAUTION! Keep doors wide open or
release brake pedal lock and move the
machine outside the storage room before
engine is started to avoid the danger from exhaust
gas.
3. Start the engine and let it run slowly. Do not
accelerate it rapidly or operate at high speed
immediately after starting.
When you purchased your tractor, you probably
had it completely equipped for your particular
needs at the time. However, later you may wish to
obtain some of the equipment or accessories shown
below. These items and other allied equipment can
be purchased from, and installed by, your
I nternational Harvester dealer.
Type of Equipment
Check air pressure in tires.
The tractor is used for so many different types of
work, and because it is called on to operate under
so many different conditions, a variety of equip-
ment is available to adapt it to the requirements of
the user.

.Refer to Service Manual.*
ENGINE OIL
The engine crankcase is filled with ship-away oil.
This oil may be used for the first 30 hours of
engine operation at temperatures between +90
degrees F. and 0 degrees F. I f temperatures are not
within this range, drain the oil from the crankcase
and replace with new oil as specified in the
"lubrication Table". The engine oil must be
drained and replaced with new oil every 30 hours
of engine operation.
To aid starting, the selection of crankcase lubri-
cating oils should be based on the lowest antici-
pated temperatures until the next drain period. See
page 31.
We recommend IH Low Ash Engine Oil for
gasoline engines. I H Low Ash Engine Oil exceeds
API Service Classification SE. It is specifically
designed for heavy duty service in gasoline engines,
and is formulated to minimize metallic deposits,
lengthen spark plug and valve life. I H Low Ash Oil
used with unleaded gasoline is the ideal combina-
tion to maintain performance and extend engine
life.
I f other than I H Low Ash Engine Oil is used it
must meet API Service Classification SE. For
maximum engine life select API SE oils with lowest
levels of barium, calcium, or magnesium additives
and minimum ash content (approximately 0.5%).
Lubricant suppliers will normally furnish this
information on their engine oils.
Multi-viscosity numbered oils such as SAE 10W-30
or SAE 10-40 must not be used above 32 degrees
Farenheit.
