INSTRUMENT PANEL
FIG. 1-2: Arrangement of gauges. Control switches and
indicators located in instrument panel. Items are detailed
in the descriptions that follow:
Electric Fuel Shut-Off
Turn the main switch to off position so as to stop engine.
Main Switch
FIG. 1-3: Main switch, 1, has the four following positions:
・pOFF - Tractor engine and all electrical circuits off.
(except for head light, turn/hazard position light,
tail light, working lamp) Key can be removed.
・OON - Power supplied to all circuits. Normal op-
erating position. Linkage on fuel injection pump
moves (electrically) to the run position.
・GGLOW - Energizes glow plugs to pre-heat com-
bustion chambers and assist starting.
・fSTART - Starter activated. This position spring
loaded to “ON”.
NOTE: Main switch must be turned to “ON” before any
circuits will operate. PTO switch must be off
and gear shift lever in neutral before engine
can be started.
This tractor is equipped with an electric fuel
shut off. When main switch, 1, is turned to
“start”, “on”, or “glow” position and gear shift
lever is placed in neutral, a solenoid moves the
fuel linkage on injection pump to run position to
start engine. When main switch is turned to “off”,
solenoid moves fuel linkage to off position to
stop engine.
・When you heard the horn sound continu-
ously on starting engine or operating For-
ward or Reverse pedal, please stop the
engine.
・In the case of the horn sound a moment
and stop on starting the engine, the ma-
chine is in a normal condition.
・When you heard the horn sound continu-
ously on traveling, apply the brake and
stop immediately. And cut off the engine.

FIG. 1-4: When main switch, 1, is selected to “GLOW”
position, glow indicator, 2, will illuminate after several
seconds to indicate the engine combustion chambers
are preheated and allow cold engine to be started.
Indicator Light Strip
FIG. 1-5: Indicator light strip, 3, contains several warning
lights to monitor certain functions. Currently used posi-
tions (from left to right) are:
・lMain (High) Beam - Illuminates when headlamps
in front grille are selected to high beam position
by light switch.
・MPower Take-Off (PTO) - Illuminates when PTO
control switch is moved to engage PTO clutch
pack (PTO operating). Light will go out when PTO
switch is moved to off.
・oEngine Oil Pressure - Illuminates if engine oil
pressure is low. If light comes on while engine is
running, shut off engine immediately and investi-
gate cause.
・bBattery Charge - Illuminates when main switch is
turned “ON” and will go out after engine starts, to
indicate battery is being charged.
・Coolant Temperature - Illuminates when engine is
overheating. Reduce engine speed to idle, allow
to run at no load sevral minutes and investigate
cause( refer to “Troubleshooting”).
・Fuel - Illuminates when fuel is low level in the fuel
tank.
・Inspection - Illuminates when hourmeter indicates
50/100/200/300/400・・・hour, please inspect
your tractor.
・Caution - Illuminates when it is not normal with
starting engine or sensor of Power shift is not
normal.
・Parking Brake - Illuminates when parking brake
lever is pulled up.
・4WD - Illuminates when 4WD is engaged by shift-
ing 4WD lever.
・† Trailer Indicator - Blink when turn switch is ON
with connecting 7 pins socket to your trailer or
when hazard light switch is ON.

Coolant Temperature Gauge
FIG. 1-6: Gauge, 4, indicates engine coolant tempera-
ture when main switch is selected to ON
・- Shows too cool temperature for severe work. Al-
low to warm before applying heavy load.
・- Indicates overheating. Reduce engine speed to
idle, allow to run at no load several minutes and
investigate cause (refer to “Troubleshooting”).
CAUTION: Do not service hot engine. Allow
to completely cool before servicing or re-
moving radiator cap.
Tachometer
FIG.1-7 & 1-8: Scale,5, indicates engine speed in crank
shaft revolutions per minute(rpm). Digital panel indicates
not only engine revolutions but also traveling speed, rear
PTO speed, mid PTO speed, hourmeter, trip meter.
Indication of digital panel is changed by pushing select-
able switch,6.
When rear PTO speed is 540, engine revolutions is ap-
proximately 2430 rpm.
Normally, the PTO speed should be between 540 and
600. Operating the PTO at a speed above 600 is too
fast, and may result in breakdown of the tractor or imple-
ment.
Hourmeter is used to assist in maintenance intervals of
tractor. The extreme right digit indicates 1 hour incre-
ments.
Tripmeter is used to assist in your operation. The ex-
treme right digit indicates 1/10 hour increments.

ing.DO NOT run out of fuel as bleeding air from
the system will be required. Keep fuel tank full
to minimize condensation.
CAUTION: DO NOT refill fuel tank with en-
gine running or hot. Allow cooling period.
DO NOT smoke near fuel tank. Clean up any
