INTRODUCTION

Tractors are definitely a special species in the
world of Automobiles and multipurpose
vehicles. I am always interested to explore
Tractors and apply innovative design principles
to them. There is a lot of scope for intervention
of Industrial Design in Indian Tractor.

I am fortunate to attain a right platform to
explore this field during my internship at TAFE.
During my Internship, I was given an
opportunity to study the evolution of TAFE
product styling and compare it with that of the
competitors.

As an extension of my internship study, I was
given an opportunity to takeup my Thesis
project in the field of Tractor in collaboration
with TAFE. After studying the form evolution of
Various Indian tractors, I was interested to
explore the possibilities of elevating the
comfort, aesthetics and user experience of
driver’s workspace of Indian tractor to develop
an wholistic knowledge of a tractor design by
combining the external styling and interior-
operational comfort.

Considering the evolution of Tractor design on
International basis and incresed demand in
Indian market, Indian tractor is going to
experience a design evolution in the coming
future. This provoked me to takeup this project
to Design futuristic concpts for Indian tractor.
considering the time span from
conceptualization to manufacturing, 2015 is
takenup as the year of target.



1. INTERNSHIP



My thesis project has got its base from my
internship project at TAFE. In this chapter I
have briefly summarized my work during
internship period.

Internship Brief: To study the evolution of form
and various aspects of TAFE/MF tractors that
make an appeal to the customer and compare
with that of competitors tractors.

INTERNSHIP
Objectives:
To study the form evolution of TAFE/MF
tractors.

To study the evolution of major competitors.

To compare the present range of TAFE/MF tra-
ctors with that of competitor tractors.

To study the current trends in domestic and
international designs.



1.1 OVERALL EVOLUTION OF TAFE/MF:
On the whole[Fig-1.1(a)], right from stubnose
bonnet to style ‘G’ bonnet, there have been
many changes in the styling that have taken
Fig-1.1(a): TAFE evolution place during the evolution which were
discussed earlier. One cannot find any drastic
change taking place during the evolution. The
identity of TAFE/MF is maintained through out
the evolution.

Some basic keywords that can be associated
with TAFE/MF product range are like;
Longish.
Bulky.
Flat.
Reliable.

INTERNSHIP
Friendly.
Strong.
Power full.

The styling has focused mostly on the feel part
of the form and gradually through the evolution,
expression is also being brought into the styling.
This can be observed from evolution of key
words related to expression like aggression and
wild along with key words like flat and longish.

The styling of TAFE/MF has its own identity in
the market and it draws no similarities or
inspirations from other existing product styling.
But, the main focus of industrial design has
TAFE/MF next generea�on only been on the hood. During further evolution
this factor may be considered and the tractor as
whole can be made more appealing. Designing
all the products together as a whole will help in
improving co-ordination and reducing visual
noise.



Fig-1.1(b): Identity Analysis During the evolution, the front grill underwent
6 many changes. In 1035 there were two
columns of horizontal bars(1) and from that.
they have slowly transformed to strong
horizontal bars(2). These horizontal bars are
further concentrated on and style ‘F’ kind of
5 expressive grill(3) came out. Finallyn this got
entirely transformed and in style ‘G’ the front
grill(4) is clean and fresh without any visual
noise and lights have taken care of the
8 expression. But, this has given up the identity
maintained by TAFE/MF.

1
Lights also underwent changes during the
evolution, the round lights(5) which used to pop

INTERNSHIP
4 out of the hood have slowly become the part(6)
of front grill. Then these round lights further
10 transformed into rectangular(7) ones. This has
9 changed the pleasant expression of the tractor
into a bit serious and masculine one. These
rectangular lights further got transformed into
sharp featured style ‘G’ lights(8). This shows
7 an indication that as being followed by the
international trends, head lights might be used
2 by TAFE/MF also to make the products more
appealing to the customer.

3 One can also observe that the products are
being made more usable and presentable by
decreasing the area of machinery being
exposed. The package and compactness
relatively increased. this can be observed from
disappearance of air filter(9) and exhaust(10)
from the external surface of style ‘G’. This is
making style ‘G’ more clean and stylish tractor.



1.2 OVERALL EVOLUTION OF MAHINDRA:
2 3 On the whole[Fig-1.2(a)], Mahindra is not
reluctant in introducing drastic changes in
styling during the evolution of its product range.
During the each stage of evolution, there has
been a considerable amount of change in the
3 styling of their products.
Due to these drastic changes in the product
styling, Mahindra could not maintain a partic-
1 ular identity for its design and there doesn’t
seem to be any Mahindra kind of styling
existing. But. they have done quite well in
maintaining certain features through out their
styling evolution which keep up their identity.

INTERNSHIP
One can observe that the cut - 1 shown in blue
can be seen in all the products of Mahindra.
All the products have front face(2) in the form
of vertically oriented rectangle. The wide
horizontal slots(3) in the front face have gained
the liking of many Indian farmers and these
slots have formed an identity for Mahindra
Fig-1.2(a): Evolution of Mahindra
during the evolution till styling ‘F’ has come into
the scene.

How ever, Mahindra seem to be following
benchmarking strategy in styling their
products. Most of their lower and medium HP
tractors seem to have some inspiration from
TAFE/MF and higher HP versions seem to have
some inspiration from John Deere. They are
always trying to catch-up the global trends and
seem to be keen in making changes to adopt
to the rapidly changing global trends.



1.3 INTERNATIONAL TRENDS:
In international market, Tractor design and
3 Styling is advancing at a very healthy pace.
Most of the international designs are focusing
on user needs and comfort to achieve user
centric design.

In Fig 1.3(a), one can observe that tractor is
not just considered as a machine. Tractor is
4 being made as stylish as other automobiles
4 and as comfortable as luxury cars.

4 One can also observe that the evolution of
electronic and sophisticated controls from the
1 early controls shows that farmers are also
2

INTERNSHIP
turning intelligent and are ready to handle
technology to work smartly for efficient out
4 put.

The fact that tractor is no more considered as
just a machine in international market can be
exemplified by how the latest hoods(1) are
covering/packing almost all the components,
how the fenders(2) are being used to cover the
front and rear wheels along with the most
important development like evolution of lux-
urious cabins(3). All these examples just show
that tractor is definitely being considered as a
posession and Tractor manufacturers started
consider user requirements and his/her tastes
before designing these wonderful machines.

There is also considerable development in the
usage of different materials and combinations.
Lights(4) are also being used as important
Fig-1.3(a): New Holland Tractor elements of of overall design



Lights of tractor are under going drastic
changes from time to time with the evolution of
tractor. Lights have become a major part of the
Fig-1.3(b): Few International Models
identity of a tractor. Different manufacturers are
2 using different style lights to create their own
2 identity.

On a whole, one can observe that there are
three basic types of lights in international
tractors with advanced design. The first type
being expressive lights(1) where the lights are
more sharp, curvy and organic in shape close
to the shape of eyes of real living thing. Lights
are generally treated as eyes of the vehicle by
industrial designers. We can observe that

INTERNSHIP
these kind of lights are already entering
domestic Indian market. Here one can observe
that New Holland confidently used their lights
to enhance the expression and these are
definitely extracted from the elements of eyes
3 from cat’s family.

The other type being long rectangular, horizon-
tally oriented lights(2) which are giving strong
outlook to the vehicle.

1 Third one being multiple lights(3). In this kind
of lights, many lights are used together in
different patterns to intelligently use them as
a part of visual identity of the vehicle.

The lights of type 2&3 might do well in
domestic market as these have a strong
outlook and gives a notion of getting ‘more’
which suits the Indian attitude of possessing big
things.



Companies in international market are keen
in forming an identity for themselves. This
6
1 seems to be a gesture extracted from luxury
1 car industry. BMW is an example for that where
they never change the design of the front grill
of their vehicles. This forms an identity for
BMW and people can recognize a BMW from a
2 distance.
2

In the same way Tractor manufacturers are
also trying to go for having their own identity.
To exemplify, one can observe that
New Holland is maintaining similarities in front
grill(1), its lights(2) and the slope(3) towards
the front of the hood. In Lamborghini tractors

INTERNSHIP
we can find that this identity is invisibly and
Fig-1.3(c): Trend Analysis sensitively maintained. Lamborghini maintains
the similar form in its tractor hood. There is a
4 line(4) which cuts the front most region of the
5 hood. A horizontal strip(5) are some things
which are maintained in common and highlights
6 the identity of Lamborghini.
5

On a whole, one can observe that the new
4 generation of international tractors got rid of
the blunt boxy kind of look and evolved into
a well designed forms with many curves and
lines. Most of the tractors are coming with
slopy hoods and as the complete coverage of
internal components has almost become
common in international market the openings
in the hood(6) for air circulationa and cooling
purpose have become part of design and they
are being well utilized by the designers.



Tractor manufacturers in international market
are using colours in an intelligent way to stand
out in the market. Colour is one of the major
assets for John Deere and New Holland.
Fendt of Agco group is good in their designs
which l are competitive and they are launching
vehicles with different colour versions.
Manufacturing of vehicles with customers
choice of colour might become common in
future just like it is in the case of Car and Bike
industry.

Tractor industry is also keeping in pace with
other automobile industries interms of
technology usage and development. Tractor
manufacturers are using different materials and

INTERNSHIP
modern sensitive technologies to keep them
selves upgraded with the latest evolutions.
New Holland has the technology of Hydrogen
Fuel cell tractor and they have concept design
for it.

Just like other advanced automobile industries,
International tractor industries are always
trying to have future concepts for their backup
and with the growing competition in this
sector, concept designs make the companies
feel secured and go ahead in global
competetive markets.

One can also observe that all the controls and
products in the operators area of the tractor
are evolving as per customer needs and these
are also being given importance just like the
importance given to interiors in car design.

4.1 EXPLORATION:

4.1.1 Self Exploration:.
As I have mentioned earlier that tractors are a
new species of Vehicles with which I had very
minimum interaction. During my system study
phase, I started with exploring the tractor by
trying to understand the way to use it, with out
any external guidence. I started with this
inorder to develop a better understanding of the
work space and the level of communication it
provides to the users.

During this process, I could identify and
Fig-4.1.1(a): Self Exploration observe many minute aspects in the

SYSTEM STUDY
workspace which influence the usage pattern
to a great extent.

4.1.2 Interaction with Drivers:
Fig-4.1.2(a): Interaction with Drivers After going through self exploration, I started
interacting with users/drivers who are actually
using the existing workspace of Indian Tractor,
to under stand the actual usage pattern being
followed by the users and to understand the
level of understanding amond the users and
the level of communication, workspace is
providing to those users.

In this process, I discussed about the problems
users are facing with the existing workspace
and the kind of improvements they are
expecting. Afetr completing these two
explorations, I could understand the function
of each and every control existing and the way
to use those controls.
