THROTTLE LEVER

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.

LIFTING THE HOOD

The tractor hood is arranged to swing up

and forward to make the engine and fuel tank

readily accessible.

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.

THE ENGINE

STARTING 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.

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.

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 releasethe
brake pedal and gradually push the choke

control button all the way in. Do not use thechoke

to enrich the fuel mixture, except when

necessary to start the engine.

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.

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.

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.

SYSTEM

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.

The fuel tank filler cap has an air vent.
Keep the vent open at all times to assure
proper flow of the fuel.

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.

FUEL SHUT.OFF VALVE

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.

THE FUEL STRAINER AND SEDIMENT BOWL

After every 25 hours of operation, cleanhe

fuel strainer as follows:

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.

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

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

Turn the high speed adjustment screw (1IIusts.

7 and 7A) counter-clockwise approximately two

turns from the closed position and start the en-gine.

After the engine has reached normal oper-

ating temperature, accelerate the engine and

check its response.

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 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.

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

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.

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.

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.

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.

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

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.

To disengage the clutch, press the pedal
approximately half way down. To stop the trac­tor press the pedal all the way down.

LOCKING THE BRAKE

Always lock the brake when the tractor is

parked on a grade. To lock the brake, press

down on the brake pedal; ther. place the brake

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.

Note: Do not rest your foot on the pedalwhile

driving the tractor, as this will result

in excessive clutch lining wear.

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.

STOPPING THE TRACTOR

Disengage the clutch by pressing the pedal
all the way down. Move the gearshift lever to

the neutral position.

CREEPER SHIFT LEVER

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

This lever is used to select various gear
ratios provided in the transmission. There
are three forward speeds and one reverse
speed. See Illust. 3. Refer to "SPECIFICA TlaNS't

on page 32.

STARTING THE TRACTOR
