OPERATOR'S MANUAL FOR
4300 FOUR-WHEEL DRIVE TRACTOR
SECTION I INTRODUCTION
GENERAL Operation and periodic service
instructions for the 4300, four-wheel drive
traeto r are con- tained in this handbook. The
tractor is made by THE FRANK G. HOUGH CO. , L i b
e r t y v i l l e, niinois. Its capacity for
work, maneuverability and fast-acting hydraulic
steering system make it a good p i e e e of
equipment for handling large capacity, heavy d u
t y agricultural implements.
operation a n d service requirements will assist
personnel in using the tracto r to best
advantage.
There are few rules which must be observ- ed. A
neglect of operating or service instruc- tions
will result in decreased tractor efficiency. It
may also cause costly down-time and repairs due
to accidents and premature failures. The
important job which the operator performs while
working the tractor will determine to a large
degree its effectiveness.
The drive train consists of a high speed,
turboeharged, four- cycle diesel engine trans-
mitting power to the drive axles through a torque
converter and power shift transmission.
LEFT and RIGHT in this m a n u a l indicate the
left and right sides of the tractor whenfac- ing
forward in the operator's s e at. Reference to
FRONT indicates the radiator end of the trac-
tor to REAR - the drawbar end.
Two gear type p u m p s supply fluid for the
hydraulic circuits of the tractor. They are gear
driven by Uie engine. The hydraulic system res-
ervoirs are p r e s s u r e sealed units t h a t
are m o u nt e d so they are easily accessible
on the right side of the tractor. A control
valve, moun- ted in front of t h e implement
reservoir, regu- lates the flow of oil to the
implement and acces- sory disconnects at the
rear of the tractor. Con- trol of the
steering-assist cylinders is regulated by a
control valve on the steering gear.
All replaceable p a rt s for this tractor are
illustrated in the parts book f o r the 4300
four- wheel drive tractor. Requests for parts or
addi- tional information for a particular tractor
should specify the tractor serial number and also
the engine and transmission serial numbers.
SERIAL NUMBERS. Record the tractor, engine and
transmission serial numbers for service and parts
replace- ment purposes. The tractor serial number
plate (figure 2) is m o u n t e d on the steering
column shrouding b e l o w the steering post. The
engine serial number (figure 3) is stamped on the
right side of the engine block below t h e rear
exhaust manifold. The transmission serial number
plate (figure 4) is located on the left side of
the trans- mission housing near the rear of the
housing. Record these numbers in the operator' s
and parts books that accompany each tractor.
The tractor wheel brakes are operated by a
compressed air s y s t e m. Compressed air for
the system is pumped by a two-cylinder, engine
driven eompresso r and is sto red in an air tank.
A treadle control valve in t h e operator's com-
partment varies the f l o w of eompressed air to
the wheel brake chambers.
Satisfactory performance of the tractor can
always be obtained if t h e operator and mainte-
nance pe rsonnel adapt the unit to existing work
conditions. Being a c qu a i nt e d with
necessary

INTRODUCTION fluid levels in the hydraulic
oil reservoirs, transmission, engine crankcase,
cooling system and the differentials and hubs of
both axles. Re- fer to Section III, Periodic
Maintenance. The tractor battery cables are
disconnected at the factory for shipping
purposes. Before con- necting the cables, check
that each battery cell is filled with enough
electrolyte to cover the cell plates. Do not
connect the cables if the tractor is to remain
in storage any length of time. Prior to
connecting the cables, refer to figure 68.
Clean the battery terminals and the inside of the
cable clamps with sandpaper or a wire brush.
Then wipe the battery tops clean, It is good
practice after connecting cables
to the battery terminals to grease them with a
heavy bodied mineral grease or petroleum. Do not
apply an excess amount as it may flow onto the
battery sealing compound and soften
it. Always observe correct polarity. Connect the
long negative lead to the negative battery power
source as shown in figure 68. Connect the long
positive lead to the positive battery power
source as shown in figure 68. Proper battery
hookup is necessary to protect the tractor charg-
ing system and to provide proper system
voltage. Connect the negative cable last.
Arrange the cable clamps so they will not
interfere with removal of the vent plugs and
arrange the cables so they will not be
chuffed. Cheek that the batteries rest level in
the holder and are properly secured. The
hold- down nuts should be tight enough to hold
the batteries secure but not so tight that either
the battery hold-down or cases are distorted.

PRELIMINARY CHECKS. Upon receipt of a new 4300,
four-wheel drive tractor or when servicing it for
active operation after a long period of storage,
the tractor should be thoroughly
inspected. Note Drain and refill crankcase with
series 3 oil prior to any operation.
Cheek that such components as the engine,
transmission, axles, drive shafts, steering gear
linkages, etc., are securely mounted. Operate all
control levers to cheek operation of the control
linkages. Should the controls fail to work prop-
erly, check for bent control rods and loose fit-
tings. Inspect all lines and connections in the
cooling, hydraulic, brake, fuel and transmission
systems.

INTRODUCTION
f. Never leave the tractor unattended with the
engine running. Place the transmis- sion lever in
neutral, set the hand brake and shut down the
engine before leaving the operator' s seat.
SAFETY PRECAUTIONS.
Farm tractors of this size, if not properly used,
are dangerous. For this reason the oper- ator
should be aware of hazardous conditions and
develop safe working habits. In this way, he can
protect himself, other personnel and the
tractor. Avoid all safety risks. Safe operation
of the traeto r, for the most part, is the
respon- sibility of the operator.
g. Stop the engine and set the hand brake
before refueling, lubricating or cleaning the
tractor. h. Avoid s moking while refueling or
using starting fluid. Do not add m a k e u p
fluid to the cooling system of a hot engine.
Give it a chance to cool before removing the
radiator cap. Remove the cap slowly to r e l e a
s e all pressure build -up in the system.
The following safety precautions are those which
are most common to a majority of wo rking
conditions. Safety precautions that are peculiar
to certain s p e c i I i e wo rk situations
should be added to this list.
Keep operating controls and hands free of
grease, water and mud to insure posi- tive
control lever movement. The deck of the
operator's compartment and the ladder must be
kept free of oil and grease to lessen the danger
of slipping.
a. M a k e sure no one is in the path of the be-
tractor a n d the attached implement
fore moving the tractor.
b. Always mount a n d dismount the traeto r on
the left side. Use the ladder provided to avoid
f a 11 s and accidental movement of control
levers. Keep the ladder clean. C. S e l e c t
the direction and a speed range that is safe for
the particular job. Oper- ate at reduced road
speeds when slippery conditions exist. d. Always
face the direction the tractor is traveling, e.
Do not carry passengers on t h e traeto r.
k. Apply the hand brake when the tracto r is p a
r k e d or when the operator's seat i s vacated.
Wheel blocks may also be need- ed to hold the
tractor if it is parked on a grade. Disconnect
the battery ground when work ing on the engine
or electrical system. m. Keep the tractor in gear
while traveling on steep slopes.

SECTION II OPERATING INSTRUCTIONS
GENERAL. This s e c t i o n desc ribes 4300, four
- wheel drive traeto r operation. Knowing how
each con- trol works and what each g a u g e
indicates will help t h e ope rato r understand
tracto r operation. This is basic knowledge t h a
t must be acquired before the t r a c t o r can
be worked effie iently. Time spent becoming
familiar with the controls and gauges found in
the operato r's compartment will be time well
spent.

While learning t h e coordination needed to wo
rk the control levers to best advantage, work
with a reduced engine speed. The development of
good operating habits while training will help
reduce tracto r service needs.

compartment (figure 8). The gauges are mounted on
the two panels in f r o nt of the operator next
to the steering c o l u m n housing. An air brake
treadle valve is mounted to the right on the
floor deck next to the steering column. The foot
throt- tle is mounted to its r i g h t. A clutch
disengage pedal is on the left side of the
steering column.

INSTRUMENT PANELS.
All gauges mounted on t h e two instrument
panels (figure 7 ) help indicate traeto r perfo
rm- ance. Check them often when the unit is
opera- ting. Best u s e of the tractor can only
be made by operating against the panel gauges.
If strange or erratic operation is noticed, t h e
gauges can help locate the trouble.
A hand throttle leve r is mounted on the left
side of the steering column housing. It wo rks
in conjunction with the foot throttle. At the
rear of the operator's seat on the r i g h t
side is a hand brake that controls operation of
the mechanical brake on the transmission. The
hydraulic con- trol levers to the ope rato r's
right control opera- tion of accessories and
implements. The trans- mission shift lever is
mounted on the tower to the right on the deck of
the operator' s compart- ment. The type steering
(two- wheel, four- wheel coordinated or c r a b)
needed is selected by the lever to the left and
rear of the operator's seat.
ENGINE OIL PRESSURE.
The engine oil pressure gauge (figure 9) in-
dicates the engine lubricating oil pressure. It
is mounted to the left on the left panel in the
upper row of gauges. W o r k i n g engine oil
pressure should range between 44 and 52 psi.

OPERATING INSTRUCTIONS Overheating indicates
the need for mechan- ical correction. A clogged
cooling system or a low coolant level will also
cause high operating temperatures. T h e engine
temperature, under full load conditions, should
remain below 195 F.
Figure 9. Engine a'! Pressure gauge The gauge
also gives some indication of the oil's e o n d i
t i o n. Pressure drops between oil changes may
be caused by d i l u t i o n, a clogged suction s
c r e e n or an internal engine oil leak. Always
cheek to find out the cause of decreased oil
pressure.
E'igure I I.
Ammeter
AMMETER. The ammeter gauge (figure 11 ) is
mounted on the left panel next to the engine
temperature gauge. It indicates electric current
flow to and from the traeto r batteries and also
gives approx- imate indications of t h e rate of
flow. Normally the gauge will show a slight
discharge when one of the electrical circuits is
turned on w i t h the engine not running. The
amount of discharge will vary with the resistance
in the electrical circuit completed.
Should the a m m e t e r show complete dis-
charge, a direct ground is indication. The cause
should be found and corrected as soon as possi-
ble. If the a m m e t e r shows a continuous dis-
charge when the engine is operating, the batter-
ies a r e being drained. Stop the engine and cor-
rect the c a u s e to prevent lowering the
battery charge. Check that the batteries have
been pro- perly connected. Refer to figure 68.
Figure 10. Engine femperofure gouge
ENGINE TEMPERATURE.
The e n g i n e temperature gauge (figure 10)
indicates the temperature of e o o l a nt passing
through the engine cooling system. It is mounted
on the left p a n e l in the u p p e r row of
gauges. Indication between 180 F. and 195 F,
are nor- mal. Continuous engine operation below
180 F. is h a r m f u 1 to the engine crankcase
oil. Low coolant temperatures will also e a u s e
exhaust smoke and increase the r a t e of fuel
consump- tion. In cold w e at h e r it may be
necessary to partially cover the engine r a d i a
t o r to prevent over-cooling.
HOURMETER.
The hourmeter (figure 12) is m o u nt e d on the
left panel below the tractor engine tempera- ture
gauge. It records hours of engine operation. A
small marker on the gauge face shows meter
operation. Use the meter readings to help estab-
lish and cheek the traeto r maintenance schedule.

OPERATING INSTRUCTIONS
WARNING LIGHTS.
AIR PRESSURE.
The wheel brakes are operated by com- pressed
air. Pressure in the air system is indi- cated
by the air gauge (figure 13) on the left panel
to the left of the hourmeter. Before moving the
tractor the gauge indicator should be in the
green area (75- 125 psi),
There are two warning lights (figure 8) on
the steering column console. Both are opera- tive
when the electrical switch is on.
The right hand light indicates the hand brake
lever position. It comes on when the hand brake
is applied and goes out when the brake lever is
released. The light should be off before moving
the tractor.
The lamp on the left of the steering column comes
on when transmission shifts are made. While on,
it indicates that the transmission torque
converter is operating in converter phase. Once
converter lock-up occurs in a selected range,
the lamp will go off.
While this lamp is on, pay particular attention
to engine speed, engine tem- perature and the
torque converter tem- perature.
Figure T3.
Air pressure gauge
For maximum economy, select a gear range that
allows minimum converter operation. Drive line
efficiency drops are considerably less when the
converter light is off.
TACHOMETER.
The tachometer (figure 14) is mounted on the left
panel to the right of the hourmeter. It in-
dicates available engine power in terms of en-
gine revolutions. Any drop in engine speed means
there is a corresponding loss of engine power.
Use the tachometer in conjunction with the shift
warning light on the steering column console to
select various transmission speed ranges. In
any selected gear range the engine should be
able to develop top speed (2100 rpm).
SPEEDOMETER.
Tractor road speed and the cumulative miles
traveled are indicated by the speedometer gauge
(figure 15) mounted on the right dash panel.
Use this gauge along with the tachometer to
select transmission speed ranges that will pre-
vent overworking the transmission and engine.

ceed 225F. for long periods of operation. Should
the converter temperature tend to remain high,
shift to the next lower transmission ratio, if
possible, to keep the converter temperature less
than 225F. Under no circumstances should the
temperature be allowed to exceed 250F.

THROTTLE. The hand throttle lever (figure 20) is
mount- ed on the left side of the steering column
hous- ing. It restricts and regulates the flow of
fuel to the engine fuel pump, In its position
nearest the operator, the lever operates a
bellcrank at the fuel pump and restrict the flow
of fuel through the pump metering plungers. This
is the way the engine is stopped. Ahead of the
lever's OFF position, it operates linkage in
conjunction with the foot throttle to regulate
fuel flow through the pump metering plungers,
Figure f 8. Aemote e/ectrical ON-OFF switch The
two switches necessary to start the en- gine (7
and 8, figure 7) and complete the various tractor
electrical circuits are mounted on the right
panel. The keyless type switch (figure 19) above
the speedometer connects all major electrical
circuits to battery power. Among the circuits
completed by this switch are the in- strument
lighting and all other lighting circuits. Its off
position is with the pointer straight up. The
first switch position clockwise from OFF
connects all but the lighting circuits to
battery power. The various positions of this
switch are illustrated in figure 19. Use the
tail light when traveling on the highway at night
or during times of poor visibility. Do not use
the nood lights for highway travel.

STEERING SELECTOR
The steering selector lever (figure 21) is the
long lever to the left of the operator's seat. It
has three position. In its upper position the
rear steering control valve is moved on a cam
surface so the rear wheels steer parallel to the
front wheels, Turning the steering wheel will
cause the tractor to crab" (oblique travel).
Direction and degree of oblique movement is
determined by the steering wheel.
FLOODS - 7AIL LIGHT HEADS DASH IGNIT ION OFF
Operating the lever to its lowest position
moves the rear steering valve so the rear wheels
steer in reverse of the front wheels. Steering
with the lever in this position causes the
tractor to turn sharply. Direction of turn is
determined by the steering wheel.
With the lever set at its mid-position, the rear
control valve is set on the steering cam so it is
non-operative. This causes the rear wheels to
stay parallel with the tractor frame. The
