Evolution of Tractors in India
Evolution of Tractors in India

• The very first tractors in India were imported by
  the British government in 1914 for the purpose of
  clearing bushes and shrubs from degraded forest
  areas and to use this cleared land for
  agricultural purposes. While these imported
  tractors were mainly used in governmental farming
  operations, they were also made available for
  hire to landowners that could afford them. By
  1930, while the use of tractors in farming still
  remained limited, an indigenous industry of
  manufacturing tractor spare parts and engines
  sprang up in India.

It is an implement that cuts and pulverizes the
soil by impact forces through a number of rotary
tines or knives mounted as a horizontal shaft. It
is also called rotary tiller. It is suitable
for shallow cultivation and weed control. It
consists of a power driven shaft on which knives
or tines are mounted to cut the soil and trash.
Rotor has got several types of tines fitted on
the shaft having a speed of 200-300 rpm.
Generally, sharp-edged L-shaped blades are used
on the rotor. According to the power used,
rotavators are classified as engine operated and
tractor-drawn rotavators.

One or two operations of this implement are
sufficient for good pulverization of soil
depending upon soil and crop conditions. It is
not meant for sandy soil. The power from the
engine to rotor shaft is transmitted through
chain or gear. A clutch is provided in the
transmission system for engaging and disengaging
power. The speed of the rotor is kept at about
350 rpm for rated rpm of 1500 of the prime mover.
The depth of penetration can be adjusted up to
12.5 cm. The suitable protective cover is
provided at the rear to prevent under a
scattering of soil.

• After India became independent in 1947, the
  Indian government placed great emphasis on
  reforming and modernizing the agricultural sector
  to pave the way towards food self-sufficiency.
  More land was brought under agricultural
  cultivation and more tractors were imported to
  speed up this task. These tractors were
  rigorously studied by Indian manufacturers,
  already well-versed in producing tractor parts
  and engines, and modified to suit Indian
  conditions, and, in 1961, Indian manufacturers
  began bringing out the first Indian-made
  tractors. Five major tractor producers Eicher
  Motors, Gujarat Tractors, TAFE Ltd., Escorts
  Tractors Ltd., Mahindra Mahindra. Domestic
  tractor production increased in the next ten
  years, but tractors still continued to be
  imported from the former Soviet Union, Poland,
  Romania, Czechoslovakia, the UK, and other
  countries.

Tractor Market in India
Many makes of rotavator are available in India
with various brand names. The some of leading
manufacturers of rotavators are   Shaktiman
Sonalika Dasmesh Group MASCHIO Mahindra
Swan John Deere Krushivator PREET

• Indian is one of the largest producers of
  tractors in the world, manufacturing around
  660,000 units per year. The main centers of
  tractor production are in the states of
  Karnataka, Maharashtra, Tamil Nadu and Gujarat,
  and the top domestic markets are in Maharashtra,
  Punjab, Haryana, Uttar Pradesh, Madhya Pradesh,
  and Andhra Pradesh. Indian tractors are also
  exported to other countries in Asia, Africa,
  Europe, and America.

Types and Uses of Tractors
To find any details information and can compare
models of many Indian-made rotavators on the
Khetigaadi website and Mobile app. Types of
rotary tiller (Rotavator) There are two types of
rotary tillers. One acts as an integral part of
the power tiller whereas the other is a separate
entity mounted on the tractor hydraulic system
and powered by the tractor PTO shaft.

• The most commonly used tractors in Indian are
  four-wheeled, 31 HP to 40 HP tractors. These can
  be put to multiple agricultural uses, and, aside
  from their price, this is the main consideration
  that farmers make in their purchase. Aside from
  their use in farms, orchards, and gardens, these
  tractors can also be used to haul produce, goods,
  equipment, and any other loads from one
  destination to another. To be able to drive the
  tractors on roads though, it is necessary for
  farmers to register them with the transportation
  department first.

Current Scenario
Types of blade used in rotavator
A. L-shaped blade Most common as the shape is
superior to others in heavy thrash. They are
better to kill weeds and generally cause less
soil pulverisation.   B. C-shapes blade
Penetrating hard ground is easier with these
blades. They are more curved than L-shaped blades
and are recommended for heavy, wet soils because
they have fewer tendencies to clog.   C. Long
shank blade They have longer shank than the
L-shaped blade and can be used for deeper
cultivation.  

• Indian farmers have become more aware of the
  benefits of farm mechanization and the role of
  the tractor in reducing farm labour drudgery,
  making multiple crops possible in a single year,
  speeding up farm operations, and reducing overall
  farm expenses.

7
D. Speed blade Especially suitable for
penetrating the hard ground and for mixing heavy
thrash. Have fewer tendencies to clog in wet
condition.   E. Straight knife blade These
simply slice through the soil to aerate and
loosen grass, eliminate soil compaction and
improve moisture penetration. The primary
application is for lawns, parks and golf courses.

• Government funding and subsidies, as well as the
  availability of nearly 95 credit from commercial
  banks, state land development banks, regional
  rural banks, and other financial institutions,
  have made it possible for a growing number of
  farmers with small-sized and medium-sized
  landholdings to purchase tractors. With the
  problem of rising labour scarcity due to
  increased migration to urban areas, better work
  opportunities in other sectors, and government
  employment schemes, having a tractor has become
  more or less of a necessity for many farmers.
  Without it, they wouldnt have sufficient
  manpower to complete all the essential farming
  tasks.

Future Industry Growth
Application of rotavator
1. Chopping and mixing Rotavator with its
chopping and mixing ability is ideal for crops
such as maize, sorghum, tobacco, sugarcane,
cotton, rice etc. The thrash mixed evenly
throughout the soil adds valuable humus to the
land.   2. Tilling and Planting To reduce
further operations, many rotavators may be
equipped with a toolbar mounted planter or a
hitch for towing a planter for tillage and
planting operations. By rearranging blades on the
rotor shaft, the rotavator may be used for strip
tillage in the seedbed.

• The future of the agricultural machinery market
  in India will continue to be influenced by the
  developments in the agricultural sector and vice
  versa. According to a report titled Agricultural
  Machinery Market in India 2017, published by
  Netscribes (India) Pvt. Ltd on the Research and
  Markets website, the projected growth of the
  Indian agricultural machinery market by 2022 is
  expected to reach 769.2 billion rupees.
• Also expected is an increased demand for more
  technologically advanced tractors with autonomous
  features, sensors, air-conditioned cabins,
  climate-controlled cabins, Internet connectivity,
  data collecting abilities, and several other
  capabilities.

3. Fertilizer and chemicals may be incorporated
by spreading in bands or broadcast from tanks or
hopper on the tractor or rotavator by
broadcasting ahead of the implement. The
stirring, mixing action of the rotavator provides
excellent incorporation of pre-emergent
chemicals.   4. Cultivating By rearranging the
blade flanges on the rotor shaft, most tillers
may be used for row crop cultivation. Rotor
diameter and operating depth are limiting factors
in the size of plants that may safely be
cultivated in this manner.

5. Orchard Tilling Rotavators are used in
vineyards, citrus groves and orchards because it
is easy to control operating depth to prevent
damage to trees or vine roots. They provide
sufficient mulch to conserve moisture. Some
rotavator models are built for offset operations.
The offset permits working under trees.   6. Rice
field Rotavators are adapted to work in wet rice
fields. The rotating blades help push the tractor
forward and reduce wheel slippage, where it would
be difficult to gain traction for plough and disc
operations. Heavy rice straw may be chopped and
mixed with the soil to improve fertility and soil
structure.

7. Weed control As many as 3-5 passes at 2-3
weeks interval may be required to completely
eradicate annual and. perennial weeds. Operate
the rotavator with a fast rotor speed and the
shield raised so that the roots are thrown on the
surface to die.   8. Pasture renovation Pasture
renovation with a rotary tiller involves breaking
up and kills the sod, mixing residues in the
soil, incorporation of fertilizers and
herbicides. Levelling of the surface and
preparation of seedbed.
