This symbol is used to call your atten-
tion to instructions concerning your
personal safety. Be sure to observe and
follow these instructions.
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.
Disengage all clutches and shift into neutral before
starting the engine. 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.
To avoid injury, disengage power to any attach-
ments and stop engine before leaving operator's
seator making any repairs or adjustments.
Know the controls and how to stop quickly.
READ THE OPERATOR'S MANUAL. 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.
To avoid an accident or injury, do not allow
children or adults to operate the equipment with-
out proper instructions. Keep children, pets, and
bystanders a safe distance away. Keep machine in good operating condition and
keep safety devices in place. Use guards or shields
as instructed in Operator's Manual.
Clear work area of objects which might be picked
up and thrown.
Disengage power to any attachment when trans-
porting or not in use. 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.
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. 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.
Reduce speed on slopes and in sharp turns to
prevent tipping or loss of control. REMEMBER -A careful operator is the best
insurance against an accident.
Stay alert for holes in terrain and other hidden
hazards. Avoid Overturns -Back the tractor up the steepest
portion of the hill to be mowed! If the tractor
cannot do this, the hiII 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 steepslopes to avoid an upset.
Before backing the tractor, always look for ob-
stacles or bystanders in the area where the tractor
will move.
To avoid the possibility of an upset, always engage
the clutch slowly, especially on steepslopes. Avoid
quick starts and stops. Do not allow anyone in the area parallel to the
discharge opening while mowing. Although the
area has been supposedly cleared of foreign ob-
jects, small objects may have been overlooked and
may be discharged by the mower causing serious
injury.
NO RIDERS! This machine is designed to safely
carryon Iy the operator. Do not carry passengers or
give rides asserious injury could result.

OPERATINGTHEENGINE
COLD WEATHER STARTING -Continued 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.
3.
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.
4.
Move the key switch into the start position and
hold until the engine starts. As soon asthe engine
starts, slowly push the choke in part way. 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 causethe 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 asthe engine warms.
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.
FUEL SYSTEM 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.
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.
ACAUTION! 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.
The carburetor isadjusted 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.
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 seepagewhen the valve is in
its full-open position.
NOTE: To prevent possible damage to the
carburetor needles, be very careful closing the
carburetor needles before basic adjustments are
made. Improper adjustment of the carburetor may
result in engine damage.

FUELSYSTEM
CARBURETOR ADJUSTMENTS -Continued If the engine missesand 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 iscorrected.
If the engine shows a sooty exhaust and issluggish
under load, the high speedmixture istoo 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 necessaryto readjust the idle adjustment
screw aseach 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 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 isobtained (1800 RPM).

Adjusting the High-Speed Adjustment Screw
Turn the high speed adjustment screw counter-
clockwise approximately two turns from the closed
position and start the engine. If the engine missesor rolls while backing out the
throttle stop screw, the idle adjustment screw may
be adjusted in or out until the engine operates
smoothly. Speed up the engine for a few seconds;
then recheck the idle adjustment. A slight adjust-
ment in or out will give the smoothest idle.
Be sure the choke is fully open (knob fully in)
when adjusting.
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.
The difference between the rich and lean points is
about 1/2 turn. Set the mixture to the rich end of
this range.
A CAUTION! Carbon monoxide fumes can
be fatal! Do not make any adjustments
to the carburetor in a confined area such
asa storage building. Move the tractor outside into
the air.

position.
Before dismounting always lock the
pedal, disengage the power take-off, and turn the
ignition "OF-F".
This
lever is used to select various gear ratios
provided in the transmission. There are three
forward speeds and one reverse speed. Refer to"SPECIFICATIONS",
on page38.
CREEPER SHIFT LEVER
The creeper drive (optional) provides a slower
speed in each respective gear, by a four-to-one
reduction in speed from direct drive. When creeper
shift lever is all the way forward, it is in direct
drive, or all the way rearward, it is in creeper drive.
STARTING THE TRACTOR
Disengage the clutch by pressing the clutch pedal
all the way down, and releasethe brake lock. Move
the gearshift lever to the desired speed. OPERATING THE CREEPER DRIVE
A CAUTION! To avoid the oossibility of
an upset, always engage the clutch slow-
ly, especially on steep slopes. Avoid
quick starts, stops.
To operate the tractor in creeper drive, depressthe
pedal and move the creeper shift lever all the way
rearward. Then select the transmission speed
desired and proceed as instructed under "Starting
the Tractor".
Start the tractor in motion by slowly releasingthe
clutch pedal and moving the throttle lever to the
position where the engine operates best for the
load to be handled.
NOTE: Do not use a mid-point position on the
creeper drive as neutral. Neutral position must be
selected only with the standard transmission gear-
shift lever.
NOTE: When using power take-off operated equip-
ment, best performance is achieved with the
throttle lever in the "Fast" position.

than to pull the unit as in plowing or mowing.
INTERNATIONAL CUB CADET 1250, 1450,
AND 1650 TRACTORS -Continued
NOTE: Do not rest your foot on the brake pedal
while driving the tractor as this would cause the
speed control lever to return to the "N" position.
4.
Move the speed control lever back to a position
to maintain proper mulching of the soil.
SPEED CONTROL LEVER 5. With a hydrostatic drive, it may be necessaryto
vary the speed control lever as the soil conditionsvary.
With a gear driven tractor, under similar
conditions it may be necessary to declutch or to
usethe brake.
This lever is used to select any speed from a
standstill "N" position to eight miles per hour in
the forward direction and to four miles per hour in
the reversedirection.
RELEASE LEVER
Moving the speed control lever forward provides
increased forward speed, and moving the lever
rearward provides the reversespeeds. Some tractors are equipped with a releaselever on
the right side of the frame near the cam stop. To
push or move the tractor for a short distance, the
release lever (if so equipped) must be held in the
(UP) position and the speed control lever (on all
models) must be in the "N" position.
SPEED CONTROL LEVER STOP
An adjustable speed control lever stop is provided
to allow the operator to return to a predetermined
speed. NOTE: Never operate engine with release lever in
(UP) position. Towing or pushing the tractor for
more than a few feet may result in transmissiondamage.
Do not bypass the speed control lever stop to
obtain a higher tractor speed. If a higher speed is
desired, reset the stop.

OPERATING THE FRONT POWER TAKE-OFF
CLUTCH The clutch is factory adjusted and should not
require further adjustment under normal operating
conditions. However, if the clutch fails to operate
properly check asfollows:
The front power take-off clutch is an electric
clutch operated by a toggle switch on the left side
of the instrument panel. Check fuse on pedestal.
1. Mdve the throttle lever back to the medium or
"slow" position. Using a feeler gauge, check the air gap! Insert the
feeler gauge into one of the access slots (Ref. 2 in
illustration) and between the clutch plates. If the
air gap is not .015/.010 inches, adjust the self-
locking nuts (Ref. 1) to obtain the proper clear-ance.
Repeat the operation in all four slots.
2. Flip the toggle switch on to the "ON" position.
