INTRODUCTION

Equipped with a high-powered· four-cylinder gasoline engine, SATOH

S-650G

tractor

does

an

extensive range

of

farming jobs. Because it

is

incorporated SATOH's latest technological innovation as well

as

many

years

ot

research

and

experience

in

manufacturing farm tractors, its

outstanding

performance

and

high efficiency have been already

recognized through

many

severest tests.

Every piece

of

the

tractor

S-650G

is

made

of

the

selected quality

materials

and

by

the

world's

most

advanced machine tools.

It

also

combines SATOH's highest standards

of

design

and

workmanship,

therefore,

both

longer service life and versatility are secured.

However,

to

work

out

these potentialities,

the

operator's

cooperation

is

a must. For this reason,

not

only

must

he

perform daily

check

and

periodical service,

but

also he

must

strictly follow

the

instructions given

in this manual.

These

instructions can

be

followed even

by

a novice,

however,

in

order

to

get easier and quicker operations, an

operator

is

requested

to

have a

fu

II

knowledge of

the

service procedures

and

a

skilled level of techniques. Once

the

operator

is

fully

acquainted

with

the

technical informations described

in

this manual,

he

will become a

qualified mechanic.

Prior

to

the

use

of

this new tractor, be sure

to

read

"Operation"

and

"Periodical Service"

in

this manual. It

is

desired

that

an

operator

keeps

this manual

on

hand

so

that

he

can look

into

it whenever necessary.

For

further questions, apply

to

your

nearest SATOH dealer, giving

The

differential lock

is

a device for making

the

rear wheels

at

the

same

.speed so

that

either

of

the

left or right wheel will

not

slip.

Fig.

11

Differential

Lock

How

to

engage

the

differential lock:

To

engage

the

differential lock,

stop

the

tractor

running before

start

to

slip

or

slow

down

the

tractor

speed, then, depress

the

pedal by

the

right

heel. Faulty engagement

at

one

time

depressing

is

requested

the

same

operation repeatedly with harder depressing. If either

of

the

left or

right wheel has already begun slipping;

turn

the

throttle

lever

to

the

idle

running or disengage

the

clutch, then, depress

the

differential lock

pedal. Make sure

that

the

pedal

is

fully depressed. As far

as

the

pedal

is

depressed,

the

lock

is

in effect.

How

to

release

the

differential lock:

Immediately after

the

right

foot

is

moved

off

the

pedal,

the

differential

lock

is

automatically released by force of

the

spring. However, it must

be remembered

that

the

lock may

not

be released

under

special

conditions.

In

this case,

the

right and left brake pedals should be

quickly

and

alternatively depressed, then,

the

differential lock

will

be

set free.

If

the

same occurs while plowing,

the

brake pedal

of

the

land

wheel side should be applied.

The

lock will be let out. When

the

both

right and left brakes are linked for towing a trailer, operation of

the

steering handle

to

right and left allows

the

lock becoming free. When

the

tractor

is

stopped with

the

differential lock applied, reverse running

with a jerk can release

the

lock.

Note: Avoid using

the

differential lock when operating

the

tractor

at

high speed

or

running

on

a road.

12. P.T.O. OPERATION

Tire slipping will

not

only damage

the

tire,

but

also waste the fuel.

If

heavier traction force

is

needed,

the

ballast weight should be attached

to

each wheel, or water can be fed into the tire tubes

in

combination

with

the

ballast weights.

In

this case,

if

atmospheric temperature tends

to

be below

the

freezing point an anti-freezing solution should be added

to

the

water.

TIRE

PRESSURE

Tire pressure should be frequently checked. Incorrect tire pressure,

either

too

high or

too

low, will result in

the

quick wear of

the

tire.

It

is

advisable

that

tire pressure should

be

checked

at

least once a week.

When water ballast

is

put

into

the

tubes, further frequent check

is

required.

A.

"Lift",

"Hold",

"Height", and

"Lower"

can be controlled by one

control lever.

B.

The operational position

of

an implement can

be

controlled by the

control lever.

C.

An automatic neutral device

is

incorporated so

that

an implement

can readily be raised and lowered

by

the

control lever.

D.

Although each valve

is

not

replaceable, spool valves and sleeves are

made

of

the

same material and their durability has been greatly

improved.

E.

The hydraulic pump

is

directly connected

to

the

engine, therefore,

the

pump operates independently from the clutch operation

..

F. Employment of

the

flow control valve has made it possible to

control the lowering speed

of

an implement. Further, an imple·

ment

can be stopped

or

locked

at

any desired position.

G.

The

hydraulic system has improved its performance and durability

by

the

use of an exclusive oil.

H.

External hydraulic valve (optional equipment) provides availability

of

hydraulically driven implements, such as

front

loader, dump

trailer, hydraulic mower, etc.

To

operate

the

SATOH

tractor

correctly, a good knowledge of the

operation of each hydra4lic mechanism

is

requested.

A.

Control lever

When

the

control lever

is

pulled toward the rear of the tractor,

the

hydraulic lift arm moves up, and pushed

toward

the

front, lowers

the

lift arm. Accordingly, an implement can be held

at

a desired

height according

to

the

type

of implements.

the

lever stopper

(see Fig. 20 A) has been set according

to

each tractor. Make no

attempt

to

change

the

stopper position

at

your

option. If

the

stopper

position had been shifted carelessly,

the

hydraulic pump

will be given

an

over load. Consult

the

nearest dealer for

correction of

the

stopper position.
