Intended use
NOTE: Your tractor is designed according to European
directives related to health and safety risks; though it
has been designed to minimize all the potential risks it is
mandatory to carefully read, understand and observe all
the decals and labels and to always refer to information
and prescriptions outlined in this manual to prevent all
residual potential risks . If you need further assistance
please do not hesitate to contact your dealer.
Your tractor is designed and made to pull, carry and
power a variety of mounted or towed equipment, al-
though within some physical limits. The working speed
and performance may depend on various factors, such
as weather and terrain conditions. Though the tractor
is designed to perform in combination with a variety of
equipment, there may be a number of combinations of the
above parameters for which there is severe degradation
of performance of the tractor and/or its mounted or trailed
equipment. If you notice degradation of performance,
contact your dealer for assistance, he may have useful
information for improvements, or a kit may be available
to enhance the performance.
Please carefully read and consider the following
precautions:
• Do not use the tractor for purposes other than those
intended by the manufacturer and outlined in this man-
ual.
• Do not use the tractor beyond its limits of terrain gradi-
ent and stability. Using the tractor beyond these limits
may result in roll-over or tip-over. Observe the recom-
mendations in this manual.
• Do not use the tractor at higher speeds than those al-
lowed by the load and the environment. A wet surface
or other low adherence conditions may increase the
braking distance or result in vehicle instability. Always
adapt your travelling speed according to the load of the
vehicle and the characteristics of the road.
• Do not use the tractor near or on soft verges of canals
and brooks or banks and verges that are undermined
by rodents. The tractor may sink sideways and roll over.
• Do not use the tractor on unstable crossings or bridges
and/or on soft surfaces or ones that are not strong
enough. These constructions may collapse and cause
roll-over of the tractor. Always inspect the condition
and carrying capacity of bridges and ramps before
crossing.
• Do not use equipment mounted on the tractor which is
not correctly matching and firmly fixed. The use of im-
plements or accessories that have not been approved
or are not correctly connected may increase the risk of
roll-over of the tractor if they come loose. Ensure that
the dimensions of the three-point linkage interface of
both the tractor and the equipment comply with the cat-
egories defined in ISO 730. Ensure that the dimensions
and speed of the PTO shaft on the tractors match those
of the equipment.
1 - GENERAL INFORMATION
• Do not use the tractor in combination with equipment
without having consulted the specific Operator's Man-
ual provided with the equipment. The tractor is a uni-
versal tool to carry, tow and drive a variety of equip-
ment. This manual alone cannot provide you with all
the information required for the safe operation of the
combination.
• Do not use the tractor for pulling work, in cases where
you do not know whether the load will yield, for instance
when pulling stumps; the tractor may flip over when the
stump is not yielding.
• Be cautious that the centre of gravity of the tractor may
increase when loads on the front-end loader or the
three-point linkage are raised. In these conditions, the
tractor may roll over earlier than expected.
• Do not step down from the tractor without shutting down
the PTO, shifting the transmission to park or neutral and
applying the park brake, unless continued PTO opera-
tion is required for some equipment, such as pumps
or wood chippers. The latter equipment may have an
emergency stop device on the equipment itself, as hu-
man intervention is needed during operation. But other
equipment, engaged and driven by the tractor will have
no means to stop the power transmission, other than
the PTO clutch of the tractor.
• You must take the necessary precautions (e.g. assis-
tance) to always be aware of the possible presence of
bystanders, especially when manoeuvring in confined
areas, such as the farm yard and sheds. Keep people
away from the tractor during work. Ask bystanders to
leave the field. There is not only the risk of being run
over by the tractor, but objects ejected by some equip-
ment mounted on the tractor, such as a rotary mower,
may cause harm. Stones may be thrown further than
the mowed crop. Pay the necessary attention while op-
erating next to public roads or footpaths. Thrown ob-
jects can be projected outside the field and hit unpro-
tected people such as cyclists or pedestrians. Wait to
cut the edge of the field till it is clear of bystanders.
• Do not allow riders on the tractor; do not allow people
to stand on the access step to the cab when the tractor
is moving. Your view to the left will be obstructed and a
rider risks falling from the tractor during unexpected or
abrupt movements.
• Always stay clear from the implements operating area
and especially do not stand between the tractor and
the implement or the trailed vehicle when operating lift
controls; ensure no bystanders are near these operat-
ing areas.
• Certain functions of your tractor are controlled by soft-
ware and some of them are safety-related. Do not at-
tempt to modify or download software not certified and
distributed by the manufacturer. Electronic settings and
logics may be destroyed and seriously affect the func-
tioning of the tractor. This may result in unpredictable
and unsafe behaviour of the tractor. Always refer to
your dealer; he has the appropriate tools and data sets
