U0Rfi SAFELï - FOLLëU ThESfi ãßLt
Instructions given with this symbol are for
personal safety. Be sure you and your workers
follow them.
A CAREFUL OPERATOR IS THE BEST INSURANCE AGAINST
AN ACCIDENT Check brakes and clutch pedal (Gear
Drive) or foot-n-inch pedal (Hydrostatic Drive)
for correct operation. Be sure muffler and
exhaust pipe are in place so exhaust gases are
discharged above the operator. Use only metric
tools on metric fasteners. Refer to
theInch-Metric Hardwaresection. Always keep the
operator's compartment clean. Keep dirt, trash,
and grease from the pedals, steps, mounting
handles, steering wheel, and controls. Before
handling ANY equipment,
Always carry a Charged fire extinguisher and a
first aid kit. Adjust tractor wheels to the
widest practical setting to reduce the
possibility of tipping.

• READ the OPERATORS MANUAL.
• MA-ìó8Z5
• Misuse or modification of this machine can cause
• mechanical breakdown,
• property damage,
• injury or death.
• Always use proper safety precautions. Tell your
  workers how to work safely.
• SERVICING AND BEFORE STARTING
• Shut off the engine and lower mounted equip- ment
  to the ground before working on the equipment.
• Carefully supervise inexperienced operators.
• Check coolant and engine oil levels, and per-
  form any other necessary services, before
  starting the engine.
• Turn the radiator cap slowly coun-

Avoid loose-fitting clothing, which would
catch on moving parts. Mounting assist handles
and steps are pro- vided for your safety. Use
them when getting on or off the
tractor. STARTING Make sure that everyone is
clear of machin- ery before starting the engine
or operation. Always sit in the tractor seat to
start the engine. Never try to do it from the
ground. Know the controls and what they do. Place
the speed transmission lever in the N
(neutral) position, engage the park brake lever
and place all other controls in neutral before
starting the engine. Be sure power take-off lever
is in the OFF or disengaged position before
starting the engine. Make sure that the helpers
or obser- vers stand clear of the equipment.
t terclockwise to the pressure release

F0LL0/ THESE RIILES
To assure the protection provided by design, the
protective structure must not be altered by
welding, cutting, drilling, or in any other
manner. Always shut off the engine before
assembling an implement PTO shaft. The shaft can
be turned by hand so the splines can be
aligned. Where possible, avoid operating the
tractor near ditches, embankments and holes. Stay
off slopes too steep for safe operation. Watch
where you are going, especially at row ends, on
roads, and around trees. TRANSPORTING Use the
flashing yellow lights and SMV emblem when the
tractor is on public roads. Obey lecal laws. Keep
warning devices clean and in good working
condition. A towed implement weighing more than
the weight of the towing tractor should be equip-
ped with its own brakes. When transporting
heavy hitch mounted equipment, lock out all
side movement and drive at a slow speed to
maintain control. When moving on public roads or
from field to field, lock the brake pedals
together for simultaneous operation when making
a stop. Refer to theWeightssection of this
manual for applicable means of adding weight to
the tractor. Reduce speed when traveling on rough
roads, sharp turns, and down steep hills. Avoid
heavily-traveled roads when moving equipment, if
at all possible. When transporting equipment on
the highway, it is recommended that a safety
chain with a rating greater than the gross load
of the towed equipment, be used. Be sure hitches
and/or drawbars are properly stabilized before
towing equipment. Be courteous, have
consideration for other traffic using the road.
DURING OPERATION NO RIDERS! Carefully supervise
inexperienced operators. Hydraulic fluid escaping
under pressure can have enough force to penetrate
the skin. Hydraulic fluid may also infect a minor
cut or opening in the skin. If injured by
escaping fluid, see a doctor at once. Serious
infection or reaction can result if medical
treatment is not given immediately. Make sure all
con- nections are tight and that hoses and lines
are in good condition before applying pres- sure
to the system. Relieve all pressure before
disconnecting the lines or performing other work
on the hydraulic system. To find a leak under
pressure use a small piece of cardboard or wood.
Never use hands. Shut off the engine and wait for
all movement to stop before servicing or
unplugging power driven equipment. Shut off the
engine and lower any mounted equipment to the
ground before working on equipment.
CAUTION! Always shift to neutral and engage the
park brake before getting off of the
tractor. Make certain that everyone is clear of
ma- chinery before starting the engine or
operating. Keep all shields in place. Use the
fixed or swinging drawbar when hitching to a
heavy trailing load. Pull only from the drawbar
or hitch. Never hitch to rear axle housing or
front axle. Check overhead clearance carefully
before driving under power lines, guy wires,
bridges, low hanging tree branches, entering or
leav- ing building, etc.

' 900 SAFELY - FOLLOIT/ THESE RIILES
TRACTORS WITHOUT ROPS (Roll Over Protective
Structure) International Harvester strongly
recommends a ROPS (roll over protective
structure). A ROPS frame is available for these
tractors. TRACTORS CAN BE ROLLED OVER. To reduce
your chance of an overturn, slow down on turns,
rough ground or hills. Hitch only to the
drawbar-never higher. Do not jerk. TRACTORS WITH
ROPS (RoII Over Protective Structure) If ROPS
(Roll Over Protective Structure) is removed from
tractor for a specific reason, the ROPS mounting
hardware must not be substituted during
reinstallation of the ROPS frame. The ROPS
mounting bolts must be tightened to a specified
torque. Torque the three 7/8 x 2-3/4 inch bolts
and nuts at each fender 570 to 637 Nom (420 to
470 lbf. ft.) Torque the four 3/4 x 10 inch bolts
and nuts at each axle carrier in an X sequence
from front to rear in four progressive steps
BEFORE DISMOUNTING Always wait for the tractor to
come to a complete stop. Always shift to neutral
and engage the park brake before getting off the
tractor. If the tractor is to be left unattended,
lower the implement to the ground, shut off the
en- gine and remove the key. Leaving the trans-
mission in gear with the engine off may not
prevent the tractor from moving. DISMOUNTING Use
the assist handles and steps provided. Step out
of the operator's area backwards.
Do not attempt to step out of the operator's area
face forward or you may fall.
First Torque 100 Nom ( 75 Ibf. It.)

CAUTION ! Total weight of the tractor and mounted
attachments should never exceed 4608 kg. (10,150
Ibs.) when the tractor is equipped with a ROPS
frame. AFTER AN UPSET No attempt should be made
to straighten, weld, or otherwise repair the
protective frame. It must be replaced in its
entirety. NOTE Do not operate the tractor or run
the engine until a thorough inspection has been
made to determine that all components, controls,
systems, etc. are operating cor- rectly. The
tractor must be inspected for other damage,
preferably, by your Interna- tional Har tester
dealer, and all necessary corrections made.

recommendations are made by Produet and Test
Engineers to assist in operating equipment at
maximum efficiency. To do so will get the most
out of dollars spent on energy.
Excessive ballast is wasteful of fuel. Use
only enough ballast to insure stability and
traction for the job being performed. Many
tractor operations do not require full load
operation. Whenever possible shift to a higher
gear and throttle back to increase economy.
However, do not "lug" the engine under these
conditions. Fuel consumption is actually
increased during "lugging" and engine life
could be shortened. Operating at as high a speed
as practical has the following advantages Less
ground compaction More work done Less equipment
cost in the form of ballast and tools Less wheel
slippage. Make the minimum number of passes over
the field, consider low tillage practices. Keep
engine speed as slow as possible for the
