WELCOME TO KEY SURVEY AND STUDY

A.WHAT IS TRACTOR

A tractor is a vehicle specifically designed to deliver a high torquefor the purposes of hauling a trailer or machinery used in agriculture or construction. Mos

tcommonly, the term is used to describe the distinctive farm vehicle: agricultural

implements may be towed behind or mounted on the tractor, and the tractor may also

provide a source of power if the implement is mechanized. The word tractor was taken

from Latin, being the agent noun of trahere "to pull". The first recorded use of the word

meaning "an engine or vehicle for pulling wagons or ploughs" occurred in

1901,displacing the earlier term traction engine (1859).Tractors are used extensively in

mowing and land-clearing applications. In fact, the common suburban riding mower is

basically a scaled-down tractor. They're also used in construction, landscaping, livestock

operations, and industrial settings.

B.BASIC OF CHOOSING A TRACTOR

Getting the right tractor is important: it's an expensive purchase and one that you can

easily last 10, 20, or 30 years or more. This Buyer Zone Tractors Buyer's Guide will help

you through the process, answering questions such as:

How much horsepower do you need?

What features are most important?

Which attachments are the most useful?

How can you choose the right dealer?

How much you can expect to pay? Start choosing a tractor by determining if one is

actually right piece for you. There are three main points to consider when choosing which

type of equipment is right for you:

FLEXIBILITY

Skid steer loaders and tractors are designed to power many kinds of attachments, while

excavators and loader/backhoes are dedicated to the specific tasks of digging and loading.


7/33

7

As a result, the specialized machines are more efficient at their specific jobs, but the

generalists are useful in more ways.

SURFACE IMPACT

Skid steers and excavator tracks can wreak havoc on grass or loose surfaces. In contrast,

even fairly substantial tractors equipped with the right tires can work on these typesof surfaces without doing noticeable damage.

OVERAGE AREA

Since they can move at faster speeds, tractors are more appropriate than skid steers for

work that involves covering a lot of ground: mowing or plowing large fields. They have

ventured in to automobile sector also with the launching of Rhino

C.WHAT ARE OUR KEY CONSIDERATIONS AND

APPLICATIONS

Once you decide that a tractor is the right purchase for you, think through the specifics of

what you'll need it do and the environment you'll be using it in. Some points to consider:

What kinds of surfaces you will be using it on?

Will it be used mainly on flat ground, or hilly terrain?

What attachments will you use?

Are there any limiting factors on the size or weight of the tractor? (Gates, garage doors,

narrow paths, small bridges)

D.HOW MUCH HORSE-POWER DO WE NEED

Once you have a handle on the types of jobs your tractor will be tackling, you can work

with a dealer to determine what horsepower you need. Horsepower is the most basic

distinction between tractor models: it dictates what work the tractor can perform, what

types of attachments it can run, and, to a large degree, how much you'll pay. Tractors with

less than 25 HP make up the small end of the market. They're capable of handling most


8/33

basic lawn work, but often can't provide enough power for more demanding jobs like

tilling or heavy brush mowing. Between 25 and 65 horsepower is a comfortable middle

ground that features tractors with capabilities suited for communities, horse farms,

nurseries, and many commercial uses. Above 65 HP, you get into tractors designed for

strenuous agricultural use, such as tilling fields and baling hay. The largest tractors forcommercial farming feature 200 HP engines or larger. Be aware: in some tractors, the

horsepower available to attachments through the power take off (PTO) connection is less

than the overall engine horsepower. Some attachments have more specific HP

requirements than others, so make sure you check these ratings carefully. Once you know

the general range of horsepower you're looking for, the best way to narrow it further is to

talk to a dealer who carries a wide range of different brands and models of tractor. The

best dealers, like those on the Buyer Zone network, will ask you specific questions

designed to help them determine exactly how much power you need. When it comes to

tractor horsepower, there are problems associated with both overbuying and under

buying. Buy a tractor that's too small and you may not be able to complete the jobs you

Have in mind. Buy one that's too large, and you'll be wasting money, as well as increasing

the turning radius, clearance requirements, and damage to the ground.

E.FEATURES

Once you decide on a base model tractor, there are several important features you

should consider

FOUR WHEEL DRIVE (4WD)

Dealers estimate that 90% to 95% of the small to medium-sized tractors they sell are four-

wheel drive (4WD) models. The reasons are simple:

4wd is critical if you want to use a loader on the front of the tractor

Tractors with 4WD have substantially better resale values

Tractors are often used on surfaces with poor traction, where 4wd is a huge benefit for

basic mowing on relatively level ground, 4WD doesn't really offer any advantages, and it


9/33

may do even more damage to finished lawns than 2-wheel drive tractors. The only time

2wheel drive is clearly a better choice is when driving the tractor for long distances at

road speeds. However, if you need to transport your tractor over long distances on a

regular basis, you'd be better off buying a trailer and transporting it that way.

ENCLOSED CABSAs in other types of small construction equipment, enclosed cabs are becoming a more

popular option with new tractors. Enclosed cabs can greatly increase operators' comfort

level when working in scorching sun or freezing temperatures. Like 4WD, cabs add a

significant amount to your initial purchase price, but also boost the resale value down the

line. They can be fairly basic an enclosure and a heater only or totally decked out, with air

conditioning and other comforts. Enclosed cabs are not available on all tractors. Because

of the power draw of the AC units (3-4 HP); they're less common on tractors less than 25

horsepower. And not all manufacturers offer cabs on all their models. But if your tractor

will see a lot of use in very hot or cold weather, the extra investment in an enclosed cab

can greatly increase their comfort and therefore their efficiency.

TRANSMISSION

While manual transmissions used to be the standard for tractors, other options are gaining

Popularity. In particular, the hydrostatic transmission, which allows clutch-free operation

in a range of speeds, has become far more common than in years past. Hydrostatic

transmissions are the best choice if the primary operators of the tractor aren't familiar with

using manual transmissions. However, they're more expensive, and they reduce the

available horsepower slightly when compared to manual transmissions. If your operators

are comfortable with using a clutch, you can save some money and get a little more

power out of your tractor by choosing a manual transmission.

SAFETY (ROPS)

All new tractors are required to come with rollover protection structures (ROPS) that

greatly improve safety. When used in conjunction with a seatbelt, ROPS prevent the

tractor from crushing the operator in a rollover accident. Another safety feature to look

for is an operator presence switch. These systems can detect the operator's weight in the

driver's seat and if there's no one in the seat, they automatically shut off the engine. Most

tractors will have basic lights and flashers for road operation, but you should check local

regulations for any rules about driving tractors on public roads to see if there are more

specific requirements.

HEAVY MACHINE SHOP

INTRODUCTION

The heavy machine shop is one of the most important shops of the industry. It plays a

very important role in the production of the tractors. As the name suggests all the heavy

components namely, the differential housing, the gear box housing, the crank case

housing, the cage and trumpet are machine here. The shop is called the backbone of the

industries.

Fig.1. Heavy Machine Shop

The heavy machine shop is divided into five sections.

1. Differential housing line2. Gear box housing line3. Cage & trumpet line4. Crankcase housing line5. Tool room

CNC Machines

Turning Centersare capable of executing many different types of lathe cutting operationssimultaneously on a rotating part. This arrangement allows quick return motion. Further

more of this allows feed rate change without any gear arrangement or control of speed of

motor. This is done by varying the eccentricity e. The higher the e, the higher the feed

rate is. A simple trade off of this feed rate control system is that as the feed rate is

reduced, the stroke of the ram also gets reduced. The hydraulic type shaper does not have

this problem and the feed rate and the stroke can be independently controlled. Figure 3-2

shows the hydraulic arrangement. This machine has been manufactured by Rockford

Machine Tool, Rockford, Illinois, USA.

G CODE AND M CODE

The entire functioning of the machine is based on G Code and M Code specifications. G

Codes define the preparatory functions of the machine. In simple terms, they control the

movement and machining related functions of the machine tool. For example, the code

"G76" followed by some related arguments is used for fine boring. "G00" with X, Y, Z

arguments rapidly move the bed and the spindle head to the position specified by the

arguments. M Codes are known as auxiliary functions. They control specific behaviors of

the machine. For example "M08" turns on the coolant, M05 stops the spindle.

Drill Press

Fig.4. Drill Press

A powered vertical drilling machine in which the rotating bit is pressed to the work by a

hand-lever. The work is secured to a table. The spindle speed is changed by selection of a

pair of step-pulley grooves. Larger drill bits turn at slower speeds. Lubricant (cutting

fluid) can be used to cool and improve cutting.

LATHE

Fig.5. Lathe

A lathe is a machine tool in which the work is held and rotated, while being shaped by a

cutting tool that is fed against the work carefully machined ways on top of the lathe bed

support and provide for precise alignment of the headstock and tailstock.

HEADSTOCK

The headstock contains the SPINDLE to which the various work holding attachments are

fitted. The spindle is hollow with the front end tapered internally to receive tools and

attachments with taper shanks. The hole permits long stock to be turned and allows a

KNOWCKOUT BAR to be used to remove taper shank tools. The spindle is usually fitted


15/33

15

with either a tapered nose or a threaded nose. Also found in the headstock is the SPEED

CONTROL MECHANISM. Power supplied by an electric motor is transmitted to the

spindle by moving the belts to positions on the pulleys or by changing the gear ratio. 21

Slower speeds on belt driven lathes are obtained by engaging the BACK GEARS. The

large gear (BULL GEAR) is keyed to the spindle and is locked to the pulley with theBULL GEAR LOCK PIN. The back gears can be engaged by disconnecting the bull gear

from the step pulley by releasing the bull gear lock pin. DO NOT ENGAGE THE BACK

GEARS WHILE THE SPINDLE IS ROTATING.

TAILSTOCK

The tailstock can be adjusted along the lathe ways to accommodate different lengths of

work. It mounts the dead center that supports the outer end of the work, and can be

fitted with cutting tools for drilling, reaming and threading. The unit is clamped to the

ways by tightening the clamp bolt nut. The spindle is positioned by rotating the

HANDWHEEL and is locked in position with the BINDING LEVER.

CARRIAGE

The carriage includes the SADDLE, APRON, CROSS AND LONGITUDINAL FEED,

SCREW CUTTING MECHANISM, COMPOUND REST and TOOL POST. The cutting

tool is supported and its actions controlled by the carriage which is moved along the ways

by hand or power feed. The power feed mechanism is located in the apron. A friction

clutch controls longitudinal and cross power feeds. Half nuts are engaged for thread

cutting.

FEED MECHANISM

The feed mechanism transmits power through a train of gears to the QUICK CHANGE

GEAR BOX, which regulates the amount of tool movement per revolution of the spindle.

The feed mechanism also contains gears for reversing tool travel. Lettering on the INDEX

PLATE tells how to position the levers for various thread cutting and feed combinations.

The LEAD SCREW transmits the power to the carriage through a gearing and clutch

arrangement in the apron. The FEED CHANGE LEVERS on the apron control the

operation of power feeds and, when placed in neutral, permit half-nuts to be engaged for

threading operations.

POWER TOOL SAFETY

Safety Tips:

Use the proper tool for the jobNever carry a tool by the cord or hose

Keep cords and hoses away from heat, oil, or sharp edges

Disconnect tools when not in use, before servicing and when changing accessories

Keep all guards in place and make sure they are working properly

Wear proper apparel. Loose clothing, long hair, and jewelry can become caught in

moving parts

Electric

Make sure tools are grounded

If working outdoors only use an outlet with GFI protection

Use double-insulated tools when possible

Do not use electric tools in damp or wet locations, and store the tools in a dry place

Hydraulic

Use approved fire-resistant fluid rated for the most extreme temperatures to which it

will be exposed

Do not exceed the manufacturers recommended safe operating pressures

Do not check for leaks using your hands because fluid under pressure may puncture

skin

PNEUMATIC

Always wear eye and hearing protection

Use a safety clip or retainer to prevent attachments, such as chisels on a chipping

hammer, from being unintentionally shot from the barrel

Fasten air hoses together securely with wire or a locking device

FUEL

Store and transport fuel only in containers approved for this application

Shut off the engine and extinguish all open flames before refueling

When operating equipment in closed areas is sure there is proper ventilation.

The Horizontal Band Saw

Fig.6. Metal Cutting Band Saw

The horizontal band saw incorporates a vise to clamp the material while the frame

holding the moving band saw blade pivots downward allowing the blade to contact and

begin cutting the material. The rate of feed is controlled by a hydraulic or spring

resistance. Please read and understand the Safety Rules in this section for both types of

band saws.

Horizontal Mill

This Mill has a spindle on a horizontal axis unlike the Vertical Mill. The cutters are

generally keyed to an arbor and driven by the spindle. A very robust and sturdy machine,

the Horizontal Mill is chosen over the Vertical Mill when large quantities of material has

to be removed by the cutters or there is less need for accuracy. A substantial vise is

required or very secure clamping techniques to secure the material to the table.

General Mill Information

COLUMN AND KNEE TYPE MILLING MACHINE


18/33

18

The column knee type milling machine is so named because the components that provide

movement to the work consists of a COLUMN that supports and guides the knee vertical

movement. The knee supports the mechanism for obtaining cross traverse and

longitudinal table movements: VERTICAL, CROSS, & LONGITUDINAL, all of which

are controlled entirely by hand levers. All milling operations fall into two maincategories:

1. FACE MILLINGThe surface machined is parallel with the face of the cutter. Large

flat surfaces are machined by this method.

2. PERIPHERAL MILLINGThe surface being machined is parallel with the periphery

of the cutter. Milling cutters come in a large number of stock shapes, sizes, and kinds to

meet many requirements.

There are two general types:

1. SOLID CUTTERThe shank and body are made in one piece.

2. INSERTED TOOTH CUTTERThe teeth are made of special cutting material and are

brazed or clamped into place. Teeth can be replaced. Consult your instructor for the type

of cutter needed.

There are two distinct cutting methods in milling operations:

1. CONVENTIONAL or UP-MILLINGThe work is fed into the rotation of the cutter.

The chip is at minimum thickness at the start of the cut and is so slight that the cutter has

a tendency to slide until sufficient pressure is built up to make it bite into the work.

2. CLIMB or DOWN-MILLINGThe work moves in the same direction as the rotation

of the cutter. Full engagement of the tooth is instantaneous. The sliding action of

conventional milling is eliminated resulting in a better finish and a longer life. Climb

milling is not recommended on light milling machines because lack of rigidity and light

support offsets any advantages of the technique.

Care of Milling Cutters and Cutter Holding & Driving Devices

1. Support the cutter properly and hold the work rigid

2. Use the correct cutting speed and feed

3. An ample supply of cutting fluid is essential

4. Use the correct cutter for the job

5. Store cutters in individual compartments or on wooden pegs

6. Clean cutters before storing


19/33

19

7. Never hammer a cutter on the arbor. Examine the arbor for burrs or nicks if the cutter

does not slip on easily.

8. Use sharp cutters End mills are held in collets or special holders while drill bits are

held in chucks that install into the spindle.

To maintain accuracy during the machining operation it is necessary to prevent damage tothe cutter holding and driving devices:

1. Keep the taper of the arbor free of nicks

2. Clean and lubricate the bearing sleeve and arbor support bearing before use

3. Clean the spacing collars before placing them on the arbor, otherwise cutter run-out

will occur.

4. Store arbors separately and in a vertical position

5. Never loosen or tighten the arbor nut unless the arbor support is locked in place

6. Use a wrench of the correct type and size

7. Do not tighten the arbor nut by striking the wrench with a hammer or mallet. This may

crack the nut or distort the threats

8. To remove an arbor or adapter from the machine:

a. Loosen the nut on the draw-in bar a few turns. DO NOT remove it from the arbor

completely

b. Tap the draw-in bar head with a lead hammer to loosen the arbor from the spindle

c. Hold the loosened arbor with one hand and unscrew the draw-bar with the other

d. Remove the arbor from the spindle, clean and store it

Cutting Speeds and Feeds, Fluids the time required to complete a milling operation and

the quality of the finish of the machined surface is almost completely governed by the

CUTTING SPEED and FEED of the cutter. Cutting Speed refers to the distance, measure

in feet, a point (tooth) on the circumference moves in one minute. It is expressed in terms

of FEET PER MINUTE (FPM) and is directly dependent on the REVOLUTIONS PER

MINUTE (RPM) of the cutter.

Feed is the rate the work moves into the cutter and is given as FEED PER TOOTH PER

REVOLUTION (FTR). The selection of the proper feed is probably the most difficult

thing for the machinist to determine. In view of the many variables; width of cut, depth of

cut, condition of the machine and cutter etc., feed should be as coarse as possible and

consistent with the desired finish. Consult the mill manual or wall chart for the speeds and

feeds required for various materials.

21/33

21

DIFFERENTIAL SYSTEM:-

FUNCTION

If the axle is a single unit and the wheels are free on the axle that is just moving on thebearings, as is the case of tractor front axle, the wheel swill turn at different speeds to

compensate for the difference in travel. However when the wheel are driven positively by

engine, a device is necessary which can make the wheels moves at different speeds on turns, whereas

the speed of both the wheels should remain equal when the tractor is following a straight path.

To accomplish this purpose a system of gears called differential system is provided.

WORKING:-

The engine drives the crown wheel mounted on the cage assembly through tail pinion. Four bevel pinions

are mounted on the bull pinion shafts lt. and rt. which are supported on the taper

roller bearings in the differential housing. These taper roller bearings give rigid support to

cage assembly. The differential system is very useful in the automobiles. This help in turning

the vehicle. As already discussed above that how the vehicle differential works while the vehicle

is taking turn. During the turning the inner speed of the wheel reduces and the outer wheel moves

faster than the inner wheels. The differential on the vehicle distributes the power between

the two wheels by giving the less power to the inner wheel than the outer one & the vehicle moves

easily. Steering system is used for the turning of the vehicle on the cross, which is fitted in

the cage assembly.

2) GEARBOX LOOPS:-

1. Gearbox housing mounted on trolley.

2. Drive shaft & input shaft assembly.

3. Output shaft assembly

5. Shifter rod assembly.

6. Steering assembly


22/33

GEAR BOX

The gearbox used in the tractors being manufactured by ITL is of the CONSTANT MESH

TYPE. This is the simplest type of gearbox. The power comes from the engine to the clutch

shaft and hence to the clutch gear which is always in mesh with a gear on the lay shaft. All the

gears on the lay shaft are fixed to it and as such they are all the time rotating when theengine is running. The clutch is engaged three and one reverse speed are attained on suitable moving the

gear on the main shaft by means of selector mechanism. The power, which the engine develops, is

transmitted to the wheels of the tractor by certain essential parts. The application of engine

power to the driving wheels through these parts is called POWER TRANSMISSION.These parts

are clutching, gearbox, differential and rear axles. To start a tractor from rest, the inertia

of its whole weight must be overcome. Diesel engine does not develop its full power at low speed. It

has to run at fairly high speed before it develops max power and torque. Since much power is needed in

starting, climbing uneven land and pulling loads, a provision must be made to permit the engine to run at

high speed while the wheels run at low speed. This is achieved by a system called

Gearbox.With the help of gearbox, we can achieve this and pulling power of the tractor can be

increased or decreased by varying the speed of tractor. For this we use ConstantMesh Gear

type.

PRINCIPLE:-

As we know that the horsepower developed is directly proportional to the product or

torque and rotational speed, i.e. H.P= K.N.T

FUNCTION

1. To convert the power of the engine running at high speed into lowspeed at high torque

2. To exchange the forward motion into the reverse motion of thevehicle.

3. To disconnect the engine from the rear wheels by putting the gearbox into neutral position.

TYPES OF GEARBOX

1. Selective gearbox

2. Sliding mesh type

3. Constant mesh type

4. Synchronous type

5. Planetary gear

will see a lot of use in very hot or cold weather, the extra investment in an enclosed cab

can greatly increase their comfort and therefore their efficiency.

TRANSMISSION

In particular, the hydrostatic transmission, which allows clutch-free operation in a rangeof speeds, has become far more common than in years past. Hydrostatic transmissions are

the best choice if the primary operators of the tractor aren't familiar with using manual

transmissions. However, they're more expensive, and they reduce the available

horsepower slightly when compared to manual transmissions. If your operators are

comfortable with using a clutch, you can save some money and get a little more power

out of your tractor by choosing a manual transmission.

SAFETY (ROPS)

All new tractors are required to come with rollover protection structures (ROPS) that

greatly improve safety. When used in conjunction with a seatbelt, ROPS prevent the

tractor from crushing the operator in a rollover accident. Another safety feature to look

for is an operator presence switch. These systems can detect the operator's weight in the

driver's seat and if there's no one in the seat, they automatically shut off the engine. Most

tractors will have basic lights and flashers for road operation, but you should check local

regulations for any rules about driving tractors on public roads to see if there are more

specific requirements.

TIRES

Your application will also determine what type of tires you should choose. Tractors can

use many types of pneumatic tires: agricultural tires for working in loose dirt; industrial

tires for heavy moving and loader work, or turf tires that reduce damage when mowing

finished lawns. Your dealer should show you several types of tires that appropriate foryour use.

TRACTOR ATTACHMENTS

While the tractor itself provides the power to get your job done, the attachments are what

actually do the work. As one dealer told us, a tractor without attachments is basically a

slow ride to the mailbox. Buying the right attachments for the job you need to do is an

essential part of a tractor purchase. The most common type of application is moving

materials around, and for that job, a front-end loader is a great choice. A simple scoop

on two arms, a loader can be used for carrying dirt, rocks, mulch, or other loose material

leveling and landscaping work; and for carrying heavy items. Unlike most attachments,

this popular tool connects to the front of the tractor, instead of the back, meaning it can be

left on while using the back end for other attachments.

Box blades

These are used to scrape or push earth, for grading, leveling, or bulldozing applications.

Mowers

These come in many types: rough cut and brush mowers for cutting through heavy growth

and finish mowers for more detailed work.

CONNECTING TRACTORS ATTACHMENTS

Most attachments connect using a three-point hitch at the back of the tractor. This lets

them use the power take-off unit (PTO) as a power source. Almost all tractors use a

standard 540 RPM PTO and three-point hitch, which means attachments are generally

interchangeable between different tractors. Verify that the horsepower rating of your PTO

is enough to run the attachments you plan on using.1000 and 2000 RPM PTOs are also

available, but unless you need a specialized attachment that only works at those speeds,

they're not important. Some tractors have a PTO located in the middle of the tractor,

beneath the operator. This can be helpful for precise mowing, but it's not very common.

CHOOSING A TRACTOR DEALER

Buying a tractor involves more than just choosing the right model and the rightattachments: you have to choose a tractor dealer you can work with for the long term.

Like any piece of heavy equipment, your tractor will wear and eventually break, making

your relationship with the dealer important. Having warranty coverage on your tractor

isn't worth much if the dealership can't do the work you need. Ask potential tractor

dealers about their service policies:

Do you provide loaners if my tractor needs to be taken in for service? Will you pick my

tractor up if it needs to go in for extensive work?

You should visit the dealers facility. Simply seeing the parts warehouse and service areas

can give you a good sense of their capabilities.

REGULAR MAINTAINENCE

Relatively simple tasks like changing the oil, replacing filters, and lubricating joints arean essential part of extending your tractor's lifespan, and many tractor owners choose to

take care of routine maintenance on their own. But in addition to repairing breakdowns,

your dealer should also help with this type of preventative maintenance. They should

provide you with a detailed maintenance manual, and walk you through the basic

maintenance procedures if necessary. They can also be your source for the parts and

supplies you need to keep the tractor running smoothly.

Handling this routine maintenance isn't difficult, but it does require that you stick to a

schedule. Because regularly scheduled maintenance is so important, it can make sense

to purchase a maintenance contract. For a small yearly fee, the dealer will make sure all

required maintenance is done right and on time, either at your location or theirs.

OTHER CONSIDERATIONS

Many tractor manufactures have been around for decades. While newer or lesser-known

brands maybe cheaper, choosing a brand with longevity helps unsure that you'll be able to

find parts when you need them. Better dealers will let you take a tractor for a demo at

your own site. This is a great way to evaluate different models: you'll be able to get a feel

for how well each performs in your specific applications. You'll also be able to directly

evaluate subjective issues like visibility and ease of use.

Lastly, dont underestimate your personal reactions. Choose a dealer you feel is honest

with you and easy to work with: those impressions are often good indicators of how the

dealer will treat you in the long run. If the dealer aggressively starts selling you on a

tractor without trying to determine your needs, you may want to keep moving. Quality

dealers want to put you in the right tractor, knowing that if you're satisfied with your

purchase, you'll eventually come back.

USAGE OF TRACTORS IN MODERN TIMES

Tractors form an integral part of farm mechanization and have a crucial role to play in

increasing agricultural productivity. Tractor is a highly versatile piece of machinery

having a multitude of uses, used in agriculture both for land reclamation and for carrying

out various crop cultivation and also employed for carrying out various operations

connected with raising the crops by attaching suitable implements and to provide the

necessary energy for performing various crop production operations involved in the

production of agricultural crops. Tractors are capital intensive, labor displaying used as a

mode of transport, in electricity generation, in construction industry and for haulage

operation. It has now become an integral part of farm structure .The application of tractor

for agricultural activities which swept India during the last twenty years have erased the

problem of farmers. Farm mechanization program in India aims to integrate the use of

available human and animal farm power with mechanical sources of power for increasing

the productivity. India is mainly an agricultural country.

Agriculture accounts for approximately 25 percent of IndiasGDP and employs nearly 62

percent of the population. It is therefore considered to be the vital sector of Indian

economy.
