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.

THE ENGINE
STARTING THE ENGINE
control button all the way in. Do not use thechoke
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.

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.

Before starting the tractor, adjust the seat to the most comfortable driving position by loosening the four cap screws in the seat sup-
port (II lust. 8) or seat bracket (1IIust. 8A) or seat spring clamping plate (1IIust.88) and sliding the
seat assembly forward or rearward to the
position which is most comfortable for theoperator.
Retighten the cap screws after the seat is
adjus ted.
The International Cub Cadet 122 and 123
Tractors features a seat which can be tilted forward over the steering wheel, for conven­ience in adjusting the seat and to keep out
rain and snow. See Illust. 8.

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.
LOCKING THE BRAKE
CREEPER SHIFT LEVER
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.
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
and proceed as instructed under "Starting the
Tractor".
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.
The following table shows the speeds avail-
able in each of the three forward gears and thereverse
