- AGRICULTURAL MACHINES EVOLUTION IN A CHANGING
WORLD
2INTRODUCTION
We are in a changing world. And the changes,
even in far distant areas, are more and more
correlated (globalization effect). So we will
focus today mainly on Europe (now extended to 27
member states), but we cannot lose contact with
the rest of the world. What is relevant to
observe is that a lot of apparently independent
changes are causing economic, environmental and
social trends with combined relevant effects on
the evolution of agricultural machines.
3BASIC STATISTICS
Our world is rapidly changing. The continuous
evolution of society, economy, technology and
culture is under our eyes, and if we give a
closer look to some statistic key indicators we
can better understand the size and direction of
change.
- Demographics
- Agricultural labor force
- Cultivated land
- Organic land
- Farm size evolution
- Climate change and precipitations evolution
- Gross Domestic Product
- Agriculture value
- Commodity prices
- Agricultural income
- Bio-fuels
4Statistics Population
Europe has 7.5 of the world population and it is
about two times the USA population but it is
much smaller than both India and China.
5Statistics Demographics
The effect of Europe net migration will no longer
outweigh the natural decrease after 2025, when
the population will start to decline gradually.
The worldwide population of the least developed
areas will pass from 5,4 billion to 7,9 billion
in 2050 while the developed areas will remain
stabilized around 1,2 billion. They would undergo
a decline normally if one did not take in account
the migration of the developing countries towards
the developed countries
6Statistics Demographics
While the European population is substantially
not growing, China, India and the USA populations
are growing around or more than 1 per year.
7Statistics Demographics
- All European countries population evolution
by age groups
Europe has grown so far only due to the addition
of new state members (from Europe-12 to
Europe-27). The European lack of population
growth is also pictured here where the main age
group trends are shown.

8Statistics Rural Population
The percentage of rural population is wide
ranging and its decreasing everywere
9Statistics Agricultural Labor Force
Over the period 1995-2000, the agricultural labor
input has declined by 2.0 p.a. in the EU15.
This rate of change has speeded up since 2000 to
-2.3 for the period up to 2005 (EU25 -2.5)

11Statistics Organic Land
The total organic area in the EU15 increased from
2.3 million hectares in 1998 to 4.9 million
hectares in 2002. The organic farming area
reached 3.8 of the total Utilised Agricultural
Area (UAA) of the EU15 in 2002, up from 1.8 in
1998 Worldwide (2006) approx. 31 million of
hectares are grown organically

14Statistics Precipitations Evolution
Difference between the winter precipitations in
the period 2070-2099 and the ones in the period
1960-1989. Figures a and b are related to two
simulations of the period 2070-2099 versus the
period 1960-1989, made with the model
ARPEGE-Climat, different only by the initial
conditions assumptions. The scale is in mm/day.
The trend on both simulations shows an increase
in winter rainfalls over Europe and a decrease
over the Mediterranean see and the Northen
Africa. The figures c and d correspond to the
figures a and b and show the same trends for the
summer rainfalls.

16Statistics Gross Domestic Product
17Statistics Agriculture value
- According to the EAA the output value at producer
prices (the producer prices excludes subsidies
less taxes on the products) of the agricultural
industry is 292 billion in 2005 for the EU25
18Statistics Commodity prices
- All the institutions are predicting significantly
higher prices for the next 10 years - than over the past decade.
- The projections are subject to many
uncertainties assumptions about productivity
growth, risks of sanitary and phyto-sanitary
crises, climate change, the weather, etc.
19Statistics Europe Agricultural Income
EU27 real agricultural income per worker rose by
5.4 in 2007, after increasing by 3.3 in 2006.
This increase was the result of a growth in real
agricultural income (3.1) and a reduction in
agricultural labour input (-2.2).
20Statistics Biofuel
Current biofuel technologies
Source IFP
- The use of vegetable oils as engine fuels may
seem insignificant today but the such oils may
become, in the course of time, as important as
petroleum and the coal tar products of the
present time. -
- Rudolph Diesel, 1912
21Statistics Biofuel
- EU Directives targets
- - Current 2 of biofuel
- - by 2010 5.75 of biofuel
- - by 2015 8 of biofuel
- - by 2020 10 of petrol and diesel to be replaced
by biofuels (20 of energy consumption coming
from renewable sources) - In 2005, 2.6 million hectares in Europe were
occupied by energy crops used to produce
biofuels 2.4 million hectares of crops to
produce biodiesel (95 rape, 5 sunflower) and
0.2 million hectares of crops to produce
bioethanol (49 wheat, 51 sugar beets) - In 2005, Europe consumed about 4.2 Mt of
biofuels, equivalent to 1.2 of road transport
fuel consumption. The European Union did not
attain its target biofuel content of 2 - which
represents 5.8 Mtoe of biofuels. - By 2010 the target is 16.6 Mtoe, which would
require about 82 Mt of farm biomass and a land
area of about 13.8 Mha. To meet this demand for
biofuel, it would be necessary to allocate a land
area for rape alone larger than the cumulated
area of all fallow land in Europe (approx. 8.2
Mha), knowing that not all of these lands are
cultivable.
22GENERAL TRENDS
From all these data we can observe, inside the
change, some clearly emerging trends
- Agricultural workforce decrease / average age
increase - Farm size increase
- more complex farm management
- Regulations evolution
- safety / health protection
- environment / pollution reduction
- Productivity / precision increase
- Bio-fuel / Bio-mass production increase
- Water shortages
- Organic cultivation expansion
23Population decrease / average age increase
- Agricultural workforce decrease (combined effect
of European population slight reduction and
decreasing agricultural percentage of the
population). - Average age of people working in agricultural
areas is increasing and this drives a strong
request for equipment ergonomic, ease of use,
low-effort controls, highly automatic operation
sequences, safe drive. - Agricultural income positive trend, in conditions
of workforce decrease, implies a significant
productivity increase.
24Farm size increase
- The progressive increase of farm size implies a
general complexity increase in the farm activity
management (more crops, more machines, more
workers). - The enterprise risk also increases and more
management skills and tools are required
(business approach, accurate accounting,
cultivation and crops planning, fleet management,
maintenance programs, purchase of services,
etc.). - The farm economic development implies a
continuous search for productivity and
efficiency, which means more machines and more
productive machines.
25Productivity / precision increase
- The demand for higher productivity on all farm
operations is constant - efficient machines
- high speed operations
- bigger machines, higher power
- automatic operations
- ease of use
- comfort
- Precision in farm operations is also an
increasing priority, because it usually increases
the efficiency in the use of machines and
materials (seeds, water, fertilizers, etc.).
26Bio-fuel / Bio-mass production increase
- The limited availability of fossil fuels and the
rapidly increasing oil prices are driving a
strong interest on bio-fuels - Both in the USA and Europe the spontaneous
extension of bio-fuel crops is supported by
dedicated governments plans.The European target
to have by 2020 10 of petrol and diesel to be
replaced by bio-fuels is going in this
direction and probably more specific support to
the bio-fuels crops will come. - The fight for low cost bio-fuel will drive even
more the productivity of these cultivations and
of the machines used for that, seen that the
available land is limited. - Bio-fuel will require wider fields for energy
crops, and farmers will require bigger machines,
with more hp, and bigger implements.
27Water shortages
- The climate changes are difficult to forecast,
but there is a general consensus among scientists
that the global warming is a real process and
that significant modifications will happen in the
next decades. - The main consequences of global warming will be a
change in precipitation pattern (probably some
increase of precipitations in Northern Europe and
a decrease of precipitations in Central and
Southern Europe). - Therefore the availability of water for
irrigation will change significantly, driving
changes in the mix of cultivations. - The demand for water will also increase
dramatically in the rest of world, with the
increase of irrigated land needs.
28Organic cultivation expansion
- In Europe the land cultivated organically is
roughly doubling every two years, leading to a
significant business impact in the agricultural
world. - The choice of non-OGM crops, the very limited use
of pesticides and herbicides and the use of
accurate cultivation methods is driving a
significant use of specialised machine work, but
with needs of clean machines, with low
emissions and high prevention of land and crop
contamination (e.g. oil drops). - This also leads to high value agricultural
production, sustained by prices higher than
average but with demand for high quality process.
29Regulations evolution
Another important trend in Europe, and in many
other countries, is the rapid evolution of
regulations. This is a direct consequence of the
social and political evolution, with increased
sensitivity to population and workers health and
safety. Air pollution and gas and particles
emissions are already strictly regulated and they
will be more. EEC legislation on agricultural
machines is quite complex and subject to
significant evolution. - machines need to
comply with a long list of EU directives -
homologation is gradually replaced by
self-certification
30Regulations evolution
- Typical examples where regulation has a
significant impact on the product design - Health and safety
- Roll over protection (ROPS), falling objects
(FOPS) - Hazardous substances
- Air purifying devices, to limit operator exposure
to hazardous substances (tractors, sprayers) - Protection of passenger
- Seat belts anchorages and location and mounting
of passenger seat - Social or horizontal Directives, intended to
cover the risks in the work sites. - Exposure of workers to the risks arising from
physical agents (vibration) - Compliance with these regulations is in charge of
the employer but, obviously, becomes a task for
the manufacturer. - Road transport
- Drive by noise
- Vehicle width, axle weights and signalisation
- Increased road speed, braking performance
- EMC (electromagnetic emission)
- Engine emissions
31Engines Emissions Targets
- Since 2000, there has been a continuous reduction
of particulate and NOx emission levels - From Tier 4 onwards exhaust after-treatment
devices will be required

34GENERAL TRENDS DRIVE MACHINE EVOLUTION
- All the trends we have seen so far have a
powerful drive into the evolution of agricultural
machines. - The combined effect of these drivers and the
evolution of technologies will cause rapid
changes and new offering in the machines
scenario. - The main evolution directions can be summarized
as follows - Bigger equipment / higher power
- Emissionised engines / clean machines / use of
bio-fuels - Safe work environment
- Higher speed
- Serviceability / maintainability improvement
- Precision farming / Auto-guidance
- Automation / CVT transmissions / electronics /
interaction with implements - Specialized products / highly configurable
products
35Bigger equipment / Higher power
- Larger fields, less manpower, demand for higher
productivity will continue driving up equipment
size and power. - Larger implements will then require more pulling
and controlling power. - The endless power up trend will continue.
36Emissionised engines / Clean machines / Use of
bio-fuels
- The future agricultural machines will be more and
more respectful of the environment.The engine
emissions regulations, already quite severe, will
continue to follow the big push for further
reduction, even in the emerging economies like
India and China. - The global push to save the environment and
respect the nature will drive our machines to
become always greener and cleaner. - The use of bio-fuels and all sort of alternative
fuels will increase significantly. Users and
dealers must become familiar with the storage,
handling and use of bio-fuels.
37Safe work environment
- The agricultural machine is often seen as a
working environment, where the operator stays for
many hours a day and where he does a lot of work
operations.European and North American
legislations are very focused on guaranteeing
safety and healthy working conditions. - This means not only safe equipment and low levels
of noise, vibration, air pollution, but also ease
of use and comfort. - Instructions must be clear and exhaustive
- Controls must be easily reachable and immediate
to understand and use. Signals and warnings have
to cover all the significant potential risks.
38Higher speed
- Even if the European legislation is a little bit
behind, the tractors speed desired by users is
often higher than 40 km/h. - 50 Km/h is becoming normal in many countries
(recently including the USA) and 60 km/h or more
is the next step. - Improved braking systems and axle suspensions
will be more and more required for a safe high
speed drive. And the same applies to trailers and
other towed machines. - But speed is also required in many other machine
operations, because it means productivity so it
will become a constant trend for complete
vehicles and for specific operations.
39Serviceability / maintainability improvement
- The social progress, the evolution of comfort
perception and quality of life and the ageing of
population will all lead a demand for better
machine serviceability. - Customers want to service their machines less
times and in an easy and safe way. - They want to access to all the relevant parts of
the equipment without risk or fatigue and easily
check the need for maintenance, in this supported
by clear on-board diagnosis. - Maintenance has to be easily planned and all the
service operations must be very simplified.
40Precision farming / Auto-guidance
- The adoption of precision farming techniques is
one of the most effective ways to increase the
yield and productivity of the agricultural land. - Satellite maps, ground and crop analysis, yield
history, culture optimization planning are now
possible with the help of services and equipment
available in the market place.And the use of
these tools is proving to be very effective in
farm operations improvement. - Auto-guidance systems will more and more drive
with precision the machines on the ideal paths,
to minimize errors and redundancies in field
operations, pulling increasingly sophisticated
large implements.
41Automation / CVT transmissions / electronics /
interaction withimplements
- The demand for productivity, ease of use and
field operations improvements will drive even
more the already exploding rate of electronic
and automatic devices on agricultural machines. - Continuous Variable Transmissions will grow at a
very high rate and electronics will become the
technology mostly spread around in our machines. - Electronic bus technology, based on existing
standards (CAN-bus, ISO-bus) and on new ones,
will transform the machines in complex integrated
systems, more and more intelligent and with
extended capabilities to communicate each other
and with implements and attachments.
42Look at this combine
43Or at this tractor driveline
44And the driver will no more be required
- The rapid evolution of the machine capabilities
will exceed the human expertise in the
agricultural domain and the machines will act
autonomously, fully robotized. - Examples will be
- machine to machine optimal settings - copying
- coordination of machine / machine activity
- fleet management (coordinating the operation
between all machines on the field for time and
efficiency gain) - Up to the full drone machine, working without any
operator on board and fully capable of
self-regulating and adapting to the field work,
taking instructions from remote computers and
operators.
45Specialized products / highly configurable
products
- In addition to the technology evolution, the
agricultural machines will also become more
specialized, to optimize their use in the various
conditions and cultivations. - This will follow a two-fold path
- true machine specialization, with specific
devices and features for a particular set of
operations - high configurability of generic machines, through
options and dealer installed accessories, to
adapt them to special work and conditions.
46Engineers Are Key Game Players
- Mechanical and agricultural engineers are key
game players in this evolving natural, social and
technological scenario. - Our best efforts should be devoted to
- - understand general change trends and
anticipate farmers and social needs - - continue pursuing innovation, not only on
technology - - identify new or specific needs of groups of
people in agriculture - - identify new product functions
- - develop new ways to provide functions.
- Knowledge, skills and innovation attitude are
needed qualities, to surf the wave of change and
shape the future of our agricultural world.
