THROTTLE LEVER
LIFTING THE HOOD
The tractor hood is arranged to swing up
and forward to make the engine and fuel tank
readily accessible.
This lever controls the speed of the engine.
When set in a given position, it will maintaina
uniform engine speed.
GOVERNOR
The governor is set at the time the engine is assembled and should not require readjust­ment unless the governor arm is removed or loosened from the governor shaft. Consult
your International Harvester dealer if the
gove rnor does not function properly.
To raise the hood, take hold of each side of the hood at the rear, pull outward, and raise it upward and forward to its stop.

to enrich the fuel mixture, except when
necessary to start the engine.
Be sure the fuel shut-off valve is open.
2. Pull the choke control button all the way
out (see Illust. 3 or 4). More or less choking may be
necessary due to variations in temperature, grade of fuel, etc. Little or none will beneeded
when the engine is warm.
Manual Starting: (Tractors without electric
starting). Raise the tractor hood. The retract-
able starter is mounted on a support plate at the front of the engine at the right side of thetractor.
Put the gearshift lever in the neutral posi-
tion and lock the brake. Turn the key ignition
switch clockwise.
3. Place the throttle lever halfway between
"SLOW" and "FAST". See Illust. 3 or 4.
4. Electric Starting: The engine cannot be
started unless the brake pedal is pressed all
the way down to activate the safety starting
switch.
Give a quick steady pull on the retractable starter handle to start the engine. Do not jerk. or pull it out to its very end in a rough manner. A steady pull will accomplish just as much.
Always pull the handle so the cord is in a
straight line through the guide. Maintain your
hold on the handle and allow the cord to return
slowly. Releasing the handle when the cable is extended will shorten the life of the starter.
International Cub Cadet 71, 102, and 122
Tractors: Check to see that the gearshift leveris
in the neutral position. See Illust. 3.
International Cub Cadet 123 Tractor: Check
to see that the speed control lever is in the
I'N'I position. See Illust. 4.
All Models: Turn the ignition key clock-wise
to the "START" position and release it as soon as the engine starts; however do not operate the motor-generator for more than 30 seconds at anyone time. If the engine does not start within this time, turn the key !'OFF" and wait a few minute s. then try again.
5. After the engine starts, slowly release
the clutch pedal and gradually push the choke
control button all the way in. Do not use the
choke to enrich the fuel mixture, except when
nece s sa ry to start the engine.STOPPING
THE ENGINE
Move the throttle lever to the "SLOW" po-
sition and allow the engine to idle for a shorttime
before stopping. Then turn the key to the
"OFF" position.
5. After the engine starts. slowly releasethe brake pedal and gradually push the choke
FUEL SHUT.OFF VALVE
FUEL
SYSTEM
Be sure the shut-off valve on the fuel
strainer under the gasoline tank is open. Screw out 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.
Fill the fuel tank with clean, fresh, regular grade gasoline, preferably at the end of each day's use. This will force out any moisture­laden air and prevent condensation in the fueltank.
Do not mix oil with the gasoline.
CLEANING
THE FUEL STRAINER AND SEDIMENT BOWL
The fuel tank filler cap has an air vent. Keep the vent open at all times to assure proper flow of the fuel.
After every 25 hours of operation, cleanhe
fuel strainer as follows:
Caution! Never remove the fuel tank cap
or fill the fuel tank when the engine is running, is hot, or when near an open flame. Do not smoke when working around inflammable fuel,as
the air around the tractor is mixed with a
highly explosive vapor. When pouring fuel, keep the container or hose nozzle in contact
with the metal of the fuel tank to avoid the
possibility of an electric spark igniting the gas. Do not spill gasoline on a hot engine.
1. Close the shut-off valve. See Illusts.7 and 7A). Loosen the knurled nut under the sediment bowl and remove the bowl and screen.
2.
Clean the sediment bowl and screen.
3. When reassembling, be sure the gasket
between the bowl and the main body is in good
condition and does not leak. Use a new gasket
if necessary.

CARBURETOR ADJUSTMENTS
For a final check of the high speed adjust­ment, operate the engine under load and make any corrections necessary for smooth opera-
tion.
Adjusting the Idle Adjustment Screw
The carburetor is adjusted at the factory and under normal operating conditions it will not require readjusting. If this adjustment has been disturbed for any reason, proceed as
follows:
Adjusting the High-Speed Adjustment Screw
After the high speed adjustment screw is
adjusted, it may be necessary to readjust the
idle adjustment screw (1IIusts. 7 and 7A), as each affects the other.
Turn the high speed adjustment screw (1IIusts.
7 and 7A) counter-clockwise approximately two
turns from the closed position and start the en-gine.
Close the idle adjustment screw to its seat by turning it clockwise; then open it one turn. Start the engine and operate it at fast idling speed (without any load) until thoroughly warm.
After the engine has reached normal oper-
ating temperature, accelerate the engine and check its response.
While the engine is running at fast idle
speed, it is advisable to screw in the throttle stop sc rew (1IIusts.7 and 7 A) 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.
Place the engine under load and turn the
high speed adjustment screw (1IIusts. 7 and 7A) to the leanest mixture that will allow satisfactory acceleration and steady governor operation.
If the engine misses and backfires under
load, the high speed mixture is too lean. The high speed adjustment screw must be turned counte r- clockwise 1 /4 turn at a time until the
condition is corrected.
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 en-
gine operates smoothly. Speed up the engine
for a few seconds; then recheck the idle ad-
justment. A slight adjustment in or out will
give the smoothest idle.
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 /4 turn at a time
until the condition is corrected.

PREPARING THE TRACTOR FOR EACH DAY'S WORK
Fill the fuel tank at the end of each day's
run. See page 6.
Check the crankcase oil level and add new
oil if necessary. Seepage 26.
Clean the air cleaner element if necessary.
See page 14.
Inspect the tires for general condition. See
pages 20 and 21.

DRIVING THE TRACTOR
(International Cub Cadet 71, 102 and 122 Tractors)
CLUTCH AND BRAKE PEDAL
Note: Do not rest your foot on the pedalwhile
driving the tractor, as this will result
in excessive clutch lining wear.
The combination clutch and brake pedal is used to disengage the engine from the trans­mission when shifting gears and to actuate the brake to stop the tractor. The pedal must be pressed all the way down to activate the safety starting switch when starting the engine.
Always be sure the rear wheels are free to turn. Under any adverse conditions, do not attempt to free the tractor by speeding up the engine and suddenly engaging the clutch. Try backing out instead of going forward.
To disengage the clutch, press the pedal approximately half way down. To stop the trac­tor press the pedal all the way down.
STOPPING THE TRACTOR
Disengage the clutch by pressing the pedal
all the way down. Move the gearshift lever to
the neutral position.

pedal lock in the engaged position. To disen-
gage the lock, press down on the brake pedal
lift the lock up and place it in the disengagE:d position behind the brake pedal as shown in
Illust. 17A.
The creeper drive provides a slower speed
in each respective gear, by a four-to-one re-
duction in speed from direct drive. When the
creeper shift lever is all the way forward, it is in direct drive, or all the way rearward, it is in creeper drive. See Illust. 3. Note: Do not use a mid-point position on the creeper driveas
neutral. Neutral position must be selected only with the standard transmission gearshift lever.
GEARSHIFT LEVER
OPERATING THE CREEPER DRIVE
To operate the tractor in creeper drive,
move the creeper shift lever (1IIust.3) all the
way rearward. Then select the speed desired

ENGINE COOLING
This tractor has an air cooled engine. Air
must be able to circulate freely around the
engine, through the screen and shroud, and over the fins of the cylinder head and cylinderblock.
Keep these areas free of accumulated dirt and trash or the engine will overheat and result in damaged moving parts.
DRY-TYPE AIR CLEANER
Incoming air for combustion is filtered by a dry-type air cleaner having a filter element inside of the cover.
Remove and clean or replace the element
with a new one when loss of power isnoticeable.
Illust. 14

Cleaning the Element
Replacing the Element
To clean the element. remove the wing nut
and air cleaner cover (1IIust. 14) then remove the
element and tap it lightl y on a flat surface to cause the loose dirt to falloff. Handle the paper element with care to avoid perforations.Do
not use compressed air to remove the dirt
as this can rupture the element. Do not wash
or use a solvent.
Replace the element with a new one if dirt
does not drop off easily or if it is bent,crushed
or damaged. When replacing the ele-
ment be sure it fits snugly around the insideedge
of the air cleaner base. Then replace the
cover and tighten the wing nut finger tight.
The twelve-volt electrical system on a
tractor with electric starting consists princi-
pally of a motor-generator, voltage regulator, and a twelve-volt battery.

SPARK PLUG
IGNITION TIMING
Note: Remove all dirt from the base of the
spark plug before removing the spark plug.
Remove the spark plug after every 100 hours of operation for cleaning and checking the gap. See Illust. 15. When making this adjust­ment, always bend the outer electrode. Never bend the center electrode, as it may damag:! the insulator. If the gap between the electrodes is too great, the engine will misfire and be hard to start.
Always use a spark plug wrench when re­moving or reinstalling the plug.
Illust.15A
Adjusting the breaker paints.
Set gap at .O20-inch.
Be sure the gasket is in good condition,
and screw the plug in tightly. Do not tighten
more than enough to compress the gasket to
seal the plug and assure a good heat transfer between the plug and the cylinder head. Tighten the plug 1/2 to 3/4 turns past finger tight.
Remove the breaker point cover after every
100 hours of operation for cleaning the points and resetting the gap (1IIust.15A). Replace badly pitted or burned points.
For more precise timing, a timing light
should be used. The engine has a timing sight hole which is located in the right s ide of the engine bearing plate on the International Cub
Cadet 71 Tractor or in the right side of the
blower housing in the International Cub Cadet
102, 122 and 123 Tractors. See Illust.15B.
With the engine running at 1/3 throttle. or
more, adjust the breaker points until the "SP" mark on the flywheel is centered in the sight
hole. Note: The "Spl' mark will appear 20degrees
before top dead center. The other mark is the top center mark and is stamped with "DC'I below the mark.
(Ilust. 15
Checking the spark plug gap.
Set gap at .O25-inch.
Replace a defective plug with a new plug.
See your International Harvester dealer for a
correct replacement plug.
Cleaning the Spark Plug
Sandblasting is the recommended method of cleaning the spark plug. Never scrape or clean the insulator with anything which will scratch the porcelain. Scratched porcelain allows
carbon and dirt to accumulate much faster.

MOTOR-GENERATORRemoving
and Replacing the Motor-Generator Belt
Replace the motor-generator belt when it
becomes badly worn. To remove the old belt,
loosen the motor-generator brace bolt I'A" and
mounting bolt.s lIB", Illust.17. Move the gener-
ator in toward the engine and slip the old belt off the pulleys and over the crankshaft. Install the new belt in the reverse order of removal and adjust the belt to the proper tension.
The motor-generator (IZ-volt, negative
ground) will function as a cranking motor when
the ignition key is turned to the "START"
position, driving the engine by means of abelt.
When the engine is operating, the unit will
function as a generator.
MOTOR-GENERATOR BELT
VOL TAGE REGULATOR
Check the tension of the motor -generator belt after the first 10 hours of operation and every 50 hours of operation thereafter. The
tension is correct when the belt can be deflected a maximum of 1/4-inch by a ten pound force applied midway between the two
pulleys.
A satisfactory generator charging rate is
maintained by the voltage regulator. If the
regulator fails to operate correctly, see your
International Harvester dealer.
Hote: Never place a jumper lead between,
or accidentally bridge, the I'BAT'I terminal
and the I'FI' terminal on the regulator, as this
will damage the regulator.
LIGHTS
The headlights are sealed-beam lights. The
parts are so constructed that the filament, re-
flector, and lens are all assembled in a unit
permanently sealed against dirt, moisture, and corrosion. If a filament burns out or a lens bxeaks, the complete unit must be re­placed. Refer to I'SPECIFICA TIONS".
TAilliGHT
To replace the taillight lamp, remove thelens
from the taillight and replace the taillight
lamp with a 4 candle power lamp. Refer to
"SPECIFICATIONS".
FUSE (Electric Lighting)
Also follow this procedure when a new beltis
installed.
Adjusting the Motor-Generator Belt
It is important to use the same capacity fuse for replacement. Refer to "Specifica­tions". If the lights fail. check the fuse. If a fuse continually burns out. check the electri-
cal wiring for short circuits.
Loosen the motor-generator brace bolt I'A'I
and mounting bolts IIBI', Illust.17.
Move the generator away from the engine
until the tension on the belt is correct. See
Illust. 16.
The fuse is located in a fuse housing in theline
at the back of the instrument panel. See
Illust. 18.
Note: Under no circumstances should a pry
bar.be used on the motor-generator to obtain
belt tension as damage to the bearings will
re suIt.
To install a new fuse. pre ss in on the fusehousing
cap and turn counterclockwise to re-move
it from the fuse housing. Remove the oldfuse
and replace it with a new one. Then re­assemble the cap to the housing. Remove the battery if necessary to reach the fuse.

STORAGE BATTERY
Keeping the battery fully charged not only adds to its life but makes it available for instant use when needed.
Battery and Cable$
Before working on any part of the electri-
cal system, disconnect the battery ground cable at the battery negative (-) terminal. See Illust. 17. Do not reconnect this cable until all work has been completed. This will prevent
shorting and damage to any of the electrical units. Examine the electrical cables occasion-
ally to be sure they are not being frayed by
contact with adjacent parts.
Liquid Level
Check the battery at least once a month for
water level.
The electrolyte (acid and water) in each
cell should be at ring level at all times to pre-
vent battery failure. When the electrolyte is
below this level, add pure, distilled water.
When replacing a battery, make certain the
ground cable is connected to the negative (-)
terminal on the battery. Be sure 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 the pedestal.
Acid or electrolyte should never be added
except by a skilled battery man. Under no
circumstances add any special battery !'dopes; 11
solutions or powders.
Cleaning and Servicing the Battery
Caution! Electric storage batteries give off
highly inflammable hydrogen gas when charg­ing and continue to do so for some time after receiving a steady charge.
Caution! Do not under any circumstances allow an electric spark or an open flame near the battery. Do not lay tools across battery terminals as this may result in a spark or
short circuit which may cause an explosion. Be careful to avoid spilling any electrolyte on hands or clothing.
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 tightly and
that the battery is fastened securely in the bat­tery box. Replace unserviceable cable. Keep the vent holes in the battery filler caps open.
For dependable battery service, see your
International Harvester dealer.

REAR TIRES
Keep tires free from oil and grease as both
destroy rubber.
6-12 rear tires are standard equipment on
the International Cub Cadet 71 and 102 Tractors.
After using the tractor for spraying-insect control work-use water to remove any chem­icals that may be on the tires.
23 x 8.50 -12 Terra-Tires are standard
equipment on the International Cub Cadet 122 and 123 Tractors. They are also available as extra equipment when ordered for the
International Cub Cadet 71 and 102 Tractors.
The Terra-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.
INFLATION
Keep the pnewnatic tires properly inflated.
Underinflation will damage the tire cord body and may also cause the tire to slip on the rim, thus tea'ring out the tube valve stem.
CARE OF TIRES
Always see that the tire valve caps are in
place and tightened securely to prevent the
loss of air and protect the valve core and stem.
Avoid stumps, stones, deep ruts and other
hazards. Cuts in tires should be repaird
immediately as neglect decreases the tire life.

CLUTCH AND BRA K E
(International Cub Cadet 71, 102 and 122 Tractors)
As the clutch and brake are both operated by the same pedal, care must be taken to maintain a neutral zone so the clutch is dis­engaged when the brake is applied.
ADJUSTING THE CLUTCH
It is important that a clearance of .050­inch be maintained between the clutch release lever and the clutch release bearing. In order
to maintain this clearance. the pedal should have a free movement of approximately 3/16-
inch. See Illust. 21. This measurement is taken
at the point of contact of the pedal arm withthe
front edge of the pedal return stop.
The clutch pedal adjustments are set at the
factory and should not require frequent atten­tion unless the linkage has been disturbed or when the pedal movement becomes less than
3/16-inch. When it is necessary to adjust the clutch, turn the adjusting nut "A" on the clutch release rod (1IIust. 22) in or out as required to
get the proper measurements.
ADJUSTING THE BRAKE
The brake should engage when. the pedal
arm is pressed down to within a maximum of l-5/l6-inches and a minimum of 3/4-inch dis­tance above the top of the left foot support,
which serves as the pedal stop. See Illust. 21.
It may be possible to push the pedal all the
way down to the pedal stop, but this is of no
concern as long as the brake is engaged when
the pedal arm is at least 3/4-inch above the
pedal stop.
To adjust the brake, loosen the jam nut "B" and turn the brake lever adjusting screw "C" (1IIust. 22) in or out as required to get thismeasurement.
The brake must not engagebefore
the pedal arm is within the maximum
distance of 1-5/16-inches above the pedal stop.

ADJUSTING THE BRAKE
The brake should engage when the pedal
arm is pressed down to within a maximum of
1-5/16-inches and a minimum of 3/4-inch dis­tance above the top of the left foot support, which serves as the pedal stop. See Illust. 23.
It may be possible to push the pedal all the way down to the pedal stop, but this is of no concern as long as the brake is engaged when the pedal arm is at least 3/4-inch above the
pedal stop.
To adjust the brake, loosen the jam nut "B"
and turn the brake lever adjusting screw "G"
(1IIust. 23A) in or out as required to get this
measurement. The brake must not engage
before the pedal arm is within the maximum
distance of 1-5/16-inches above the pedal stop.
ADJUSTING THE SPEED CONTROL LEVER
Note: The brake pedal must be properly ad-
justed before beginning the speed control lever
adjustment. If the tractor "creeps" in the "N" position or, if the speed control linkage has been disassembled or removed for any reason, the following adjustment must be made.
Block the tractor so the left rear wheel is
off the ground.
Start the engine at half throttle or faster.
Move the speed control lever to the forward position. The rear wheel should rotate in the forward direction. Depress the brake pedal all the way down and release. The speed control
lever should return to the "N't position and the
rear wheel stop turning.
If the rear wheel turns in the forward direc-
tion, loosen jam nut "D" and turn the connect­ing rod "E" counterclockwise to lengthen it
until the wheel stops turning. (See Illust. 23A).

Accidentsbe
with
No accident-prevention program can be suc-
cessful without the wholehearted co-operation
of the person who is directly responsible for the operation of equipment.
To read accident reports from allover the country is to be convinced that a large number of accidents can be prevented only by the
operator anticipating the result before the accident is caused and doing something about it. No power-driven equipment, whether it be
transportation or processing, whether it be on
the highway, in the harvest field or in the
industrial plant, can be safer than the man who is at the controls. If accidents are to be pre-vented
and they can be prevented-it will bedone
by the operators who accept a full measure
of their responsibility.
It is true that the designer, the manufacturer, the safety engineer can help; and they will help, but their combined efforts can be wiped out by a single careless act of the operator.
It is said that' 'the best kind of a safety device is a careful operator. '! We ask you
to be that kind of an operator.
