Introduction
This manual has been written to provide the owner and
user with reliable and clear instructions on tractor
operation and maintenance.
By following the instructions in the manual, you will
not only get many years of efficient and faithful service
from your MCCORMICK tractor, but you will make your
work much easier.
Your dealer will give you operating and maintenance
instructions when you take delivery of your new tractor
and will make sure you have understood them
correctly. However, should any part of this manual not
be clear to you, do not hesitate to contact your
nearest dealer for explanations. It is very important for
you to understand and strictly comply with these
instructions. Carry out the maintenance checks daily
and keep note of the number of hours the tractor has
worked.
Use only genuine MCCORMICK spare parts when
replacements are required. MCCORMICK local agents
not only supply genuine spare parts. They can also
give useful hints and instructions on how they are to
be mounted and used. Remember that non-genuine
parts can damage other components. You are
therefore strongly advised to purchase any spare parts
that may be necessary from an authorized
MCCORMICK agent or dealer.
The tremendous variety of conditions in which tractors
work the world over mean that MCCORMICK cannot
provide perfectly accurate and up to date information
on the performance and efficiency of the tractors it
manufactures. The company therefore accepts no
responsibility for loss or damage caused by its
publications or any error or omission therein. Should
the vehicle ever be used in particularly adverse
conditions (e.g. in heavy soils or very muddy condi-
tions) contact your local dealer for specific instruc-
tions. Failure to do so may render null and void the
warranty on your tractor.
Customers are strongly advised to refer any difficulties
in use or assistance to authorized dealers. The
MCCORMICKdealership network is specially equipped
and trained to provide assistance and to advise
customers on how to use the tractor in special
working conditions.
The names and addresses of dealers throughout the
world may be obtained from the address indicated on
the next page.

Warranty, pre-delivery inspection,
and delivery
New products purchased through authorized dealers
are guaranteed, within certain limits, against defects in
materials and manufacture.
This manual is published for world-wide distribution. It
is thus impossible to describe the exact terms and
conditions of warranties in every single country.
Purchasers of new tractors are kindly requested to
ask their local Dealer for full details.
Since it is a MCCORMICK policy to make constant
improvements to all its products, the specifications of
its tractors may be modified at any moment and
without notice.
MCCORMICK declines all responsibility for
discrepancies between a tractor's actual features and
the descriptions given in this manual.
Your dealer is obliged to provide a number of specific
services when delivering a new tractor.
These services include a thorough examination of the
tractor prior to delivery to ensure that it is perfectly
functional and ready for immediate use, and an
explanation of all tractor operating and maintenance
instructions. These instructions cover the instruments
and controls, periodical maintenance and safety
precautions.
It is essential for all those involved in tractor operation
or maintenance to participate in this course.
MCCORMICKdeclines all responsibility for any damage
caused by the use of non-approved parts.
NOTE: Please refer to the 'Warranty Book' provided
with each tractor sold for the conditions of warranty or
for any problems concerning them.
NOTE: MCCORMICK declines all responsibility in the
case of claims for damages deriving from use of spare
parts or accessories that are not of the approved type.
Safety notes
The operator's safety is one of the main concerns of
those who design and develop new tractors and the
greatest possible number of safety devices are
included. Despite this fact, many accidents happen
every year that could have been avoided if the
operator had taken greater care when handling
farming machinery and equipment. Read this manual!
It will help you to avoid potential accidents. To
illustrate parts more clearly, some of the drawings in
this manual show panels or guards removed.
Remember that the tractor must never be used in
these conditions. Leave all panels and guards in place.
If you have to remove one to carry out repairs, you
MUST fit it back in place before starting the tractor.
Remove and replace guards ONLY with the engine
switched off. DO NOT remove or cancel any Caution,
Warning or Danger Instruction decals. Replace decals
that are missing or illegible. If the decals are missing
or damaged, new ones can be obtained from your
local dealer. The exact position for each safety decal
is shown in this manual. If you have purchased a used
tractor second-hand, check to make sure that all
safety decals are in the right positions and that they
are perfectly legible.
Use of the tractor on public roads
USA and Canada only
When driving the tractor and its implements on main
and secondary roads (at a speed of no more than 40
kph (25 mph), by day or by night, turn on the side
lights and display a Slow-Moving Vehicle sign. In most
places, the use of flashing amber warning lights is
permitted. In some areas however, use of these lights
is forbidden by law. Make sure you are familiar with
local legal requirements for warning lights and vehicle
identification symbols when driving on main roads.
Use the safety chain. Consult the operator's instruction
manual provided with the implement or the farming
machine attached to your tractor.
All other countries
Make sure you are familiar with the traffic regulations
and abide by statutory regulations when driving your
tractor on public roads, with or without any
implements in tow. Always observe any regulations
concerning the transport of projecting equipment or
loads.

SAFETY AND DANGER SYMBOLS AND TERMS
This safety symbol means WARNING! BE CAREFUL YOU ARE IN DANGER!
This warning symbol shows that the manual contains important safety information about the machine.
When you see this symbol, watch out for potentially serious injury to the person.
Comply with the instructions given in the safety message.
WHY IS SAFETY IMPORTANT FOR YOU?
 ACCIDENTS CAN MAIM OR KILL 
 ACCIDENTS ARE COSTLY 
 ACCIDENTS ARE AVOIDABLE 
Safety on the tractor and implement
The tractor is a source of - Mechanical power - Hydraulic power.
On its own, a tractor is of little practical value.
Only when it is used with an implement or other equipment does it become a working unit.
This manual has been written to explain safe working practices that must be applied when using the tractor.
It does not cover all safety operations and instructions for all available implements and equipment that may be fitted
at the time of delivery or at some later date.
The operator must understand and abide by the instructions provided in the manuals of such implements and
equipment.
Safety: rules for the operator
It is YOUR responsibility to read and understand the
safety section in this manual before you start using
the tractor. You must follow these safety instructions
as they take you step by step through your working
day.
In reading this section, you will notice that illustrations
are used to explain certain potentially dangerous
situations. Each illustration has a number and the
same number appears in brackets in the text. This
number is placed at the end of the text that refers to
the illustration.
Always remember that YOU are responsible for your
safety. Good safety practices not only protect you, but
also the people around you. Make sure you fully
understand the safety measures in this manual and
apply them at all times.
Safety: introduction
The safety section of your Operation and Maintenance
manual intends to highlight and point out some of the
safety situations that you may come across during
normal use and maintenance of your tractor and to
suggest ways of dealing with these circumstances.
This section does NOT substitute any other safety
regulations mentioned in other parts of this manual.
Extra precautions may be necessary depending on the
implements being used and the operating conditions
at the work site or in the service area. MCCORMICK
has no direct control over the applications, operations,
inspection, lubrication or maintenance of the tractor
and it is thus YOUR responsibility to follow good
safety practices at all times.

are not readable or are missing. Replacement
decals are available from your Dealer in the
event of loss or damage. The location of these
Safety Decals is illustrated at the end of this
section.
If a used tractor has been purchased, refer to the
illustrations at the end of this section to ensure that all
the safety warning decals are in the correct position
and are readable.
Follow the safety regulations
For safe operation
For safe operation, only fully qualified and authorized
operators are to use tractors. To qualify as an operator,
you must understand the instructions in this manual,
have training and know and understand the relevant
safety and work regulations.
For example, some regulations specify that nobody
under the age of 16 may use a work vehicle: this
includes tractors. It is your responsibility to know
these regulations and to comply with them at all
times.
They include the following instructions for using the
tractor safely.
WARNING: The operator must never use alcohol
or drugs that can affect his attention or the
coordination of his movements. An operator
who is prescribed narcotics or who uses them in
controlled amounts must have medical
authorization to use the tractor in conditions of
safety.
Observe the following precautions
• DO NOT allow children or unauthorized persons to
drive your tractor.
• Fasten your seat belt if the tractor is fitted with a
roll-over protective structure.
• Whenever possible, do not use the tractor near
ditches or embankments.
• Reduce speed when turning the tractor, crossing
slopes and on rough, slippery or muddy surfaces.
• Keep clear of slopes too steep for safe operation.
• Watch where you are going - especially at row
ends and around trees.
• NEVER let anyone else ride the tractor or the
implement.
• Operate the tractor smoothly, with no sudden
movements: do not turn, start or stop abruptly.
• Hitch only to the drawbar and recommended hitch
points - NEVER hitch above the central line of the
rear axle.
• Apply the parking brake whenever the tractor is
stopped.
• Never alter or remove any part of the equipment.
• Keep others well clear of your work area.
• NEVER use attachments that are not designed for
your tractor.
Safety notes

8. 8
Roll Over Protective Structure
(ROPS)
Roll over protective structure (ROPS)
Either a roll-over protective structure or a cab is
mounted as standard equipment together with a seat
belt: if the safety structure or cab have been removed,
you are advised to fit the tractor with a safety
structure or cab and a seat belt. A ROPS structure or a
ROPS cab reduce the risk of injury should the tractor
roll over. Rolling over without a ROPS or ROPS cab
can cause damage, serious injury or death.
Use
• Before using the tractor, ensure that the ROPS
frame or the ROPS cab has not been damaged and
that it is securely fastened to the tractor.
• DO NOT attach chains, cables, etc. to the ROPS
frame or to the ROPS cab for towing purposes as
this could cause the tractor to tip up: always use the
drawbar for this purpose.
• Always fasten your seat belt (only if applicable). Do
not wear the seat belt if the tractor is not equipped
with a ROPS or cab.
• Check the seat belt for damage. Damaged belts
must be replaced.
Damaged ROPS or cabs
If the tractor has rolled over and the ROPS or the cab
have been damaged, they must be replaced in order to
ensure the original degree of protection.
After an accident, check the ROPS or cab, the driving
seat, the seat belt and the anchor points of the seat
belt. Replace all damaged parts before using the tractor
again.
DO NOT WELD, DRILL, BEND OR STRAIGHTEN THE
ROPS OR CAB: to do so reduces the degree of protec-
tion that is ensured by the original equipment.
Safety precautions
Protect yourself
Wear all protective clothing and any personal protection
devices called for by the work conditions. Never take
risks (Fig. 1. 2).
You need the following protective clothing:
• A hard hat.
• Safety goggles or mask.
• Hearing protection.
• Respirator or filter mask.
• Clothing for bad weather.
• Reflective clothing.
• Heavy duty gloves (neoprene for chemicals, leather
for heavy duty jobs).
• Safety shoes.
