To The Owner
Y our new I nternational Harvester tractor is design-
ed to meet today's exacting operating require-

ability to match ground speeds to engine power
and work requirement, and the effort less versatil-
ity of the hydraulic system are intended to lighten
your work and shorten your hours on the job.
Your local International Harvester dealer is inter-
ested in the performance you receive from this
tractor. He has factory trained servicemen, inform-
ed in the latest method of servicing tractors, and
modern tools, and original-equipm.ent IH service
parts
which assure proper fit and good perform-
ance.
To obtain top performance and assure economical
operation the tractor shou Id be inspected, depend-
ing on its use, periodically, or at least once a year,
'by your International Harvester Dealer.

carefully. It has been prepared to help you operate
and
maintain your tractor with utmost efficiency.
New copies may be ordered from your dealer at
a nominal price.

of parts, always specify the tractor
and engine serial numbers, including prefix and
suffix letters. Write these serial numbers in the
spaces provided below.

ing.
Alwa ys k ee p the tractor in gear when going down
hill s. A to w ed vehicle having a grossw ei g ht greater
than
th e weight of the towing tracto r must be
equipp ed with its own brakes.
Stay alert for holes, rocks, tree stum ps and other
hazards in terrain which coulid ca use an upset or
loss of control which could result in inj ur y.
Use care when pulling loads or using heavy equip-
ment:
A.
Use only approved hitch points.
B. Limit loads to those you can safely control.
C. Don't turn too sharp, and use care when
backing.
D. Use counterweight or wheel weights when
suggested in Operator's Manual

Al w ays avoid sudden starts, excessive speed, and
su dden stops.
To assure the protection provided by design, the
pro tective frame must not be altered by welding,
cu tt ing, drilling, or in any other manner.

TRANSP ORTING
Use warning devices (i.e. flags, S.M.V. emblem,
light
s, etc.) which are approved for use by your
loc al government agencies, when moving equip-
me nt on public roads. Keep these devices clean and
in good
working condition.
Before moving on public roads, or from field to
field, lock the brake pedals together for simultane-
o us operation.
Red uce speed when traveling on rough roads, sharp
tu rns, and down steep hills.
For your safety, avoid he avily-traveled roads when
moving equipment.
Be sure hitches and/or drawbars are properly stabil-
liz
ed before towing equipment. Be courteous, have
consider
ation for other traffic using the road.

WORK SAFELY -FOllOW T HE SE RUL ES
When transporting on the highway, use a safety
chain with a
10,500 pound (4767 kg) gross load
