Japan Used Tractors

 

A tractor is an engineering vehicle specifically designed to deliver at a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery used in agriculture or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially (and originally) tillage, but nowadays a great variety of tasks. 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 mechanised.

 

History of Tractor:

In 19th century the first farm implements were Portable engines- steam engines on wheels that could be used to drive mechanical farm machinery by way of a flexible belt. Richard Trevithick designed the first ‘semi-portable’ stationary steam engine for agriculture use, in year 1812. In 1839 William Tuxford invented the truly portable engine, a large flywheel was mounted on

the crankshaft, and a stout leather belt was used to transfer the drive to the equipment being driven. In the 1850 John Fowler used a clayton & shuttleworth portable engine to drive apparatus in the first public demonstration of the application of cable haulage to cultivation. In year 1892 John froelich invented the first successful gasoline-powered engine that could be driven backwards and forwards. The word “ tractor” wasn’t used in those days, but that’s what it was. At that time, steam -powered engines were used to thresh wheat.

 

Gasoline Powered Tractor: 

Froelich worked with his blacksmith developed a vertical one-cylinder engine mounted on the running gear of a steam tractor engine and developed parts to make it all work together. Soon Froelich and his crew were using it to threshed 72,000 bushels of small grain.

 

Farm tractor design power and transmission:

Tractors can be generally classified by number of axles or wheels, with main categories of two-wheel tractors among four-wheel tractors (two-axle tractors), most are two-wheel drive (usually at the rear); but many are two-wheel drive with front wheel assist, four-wheel drive (often with articulated steering), or track tractors (with steel or rubber tracks).The classic farm tractor is a simple open vehicle, with two very large driving wheels on an axle below and slightly behind a single seat (the seat and steering wheel consequently are in the center), and the engine in front of the driver, with two steerable wheels below the engine compartment. Four-wheel drive tractors began to appear in the 1960s. Some four-wheel drive tractors have the standard "two large, two small" configuration typical of smaller tractors, while some have four large, powered wheels. The larger tractors are typically an articulated, center-hinged design steered by hydraulic cylinders that move the forward power unit while the trailing unit is not steered separately. In the early 21st century, articulated or non-articulated, steerable multitrack tractors have largely supplanted the Caterpillar type for farm use. Larger types of modern farm tractors include articulated four-wheel or eight-wheel drive units with one or two power units which are hinged in the middle and steered by hydraulic clutches or pumps. A relatively recent development is the replacement of wheels or steel crawler-type tracks with flexible, steel-reinforced rubber tracks, usually powered by hydrostatic or completely hydraulic driving mechanisms. The configuration of these tractors bears little resemblance to the classic farm tractor design

 

Engines and Fuels:  

The predecessors of modern tractors, traction engines, used steam engines for power.

 

Gasoline and Kerosene:

Since the turn of the 20th century, internal combustion engines have been the power source of choice. Between 1900 and 1960, gasoline was predominant fuel, with kerosene and ethanol being common alternatives. Generally, one engine could burn any of those, although cold starting was easiest on gasoline. Often, a small auxiliary fuel tank was available to hold gasoline for cold starting and warm-up, while the main fuel tank held whatever fuel was most convenient or least expensive for the particular farmer.

Diesel: Dieselisation gained momentum starting in the 1960s, and modern farm tractors usually employ diesel engines, which power output from 18 to 575 horsepower. Size and output are dependent on applications, with smaller tractors used for lawn mowing, landscaping, orchard work, and truck farming ,and larger tractors for vast fields of wheat, maize, soy, and other bulk crops

 

Liquefied Petroleum Gas:

Liquefied petroleum gas (LPG) or propane also have been used as tractor fuels, but require special pressurized fuel tanks and filling equipment, so are less prevalent in most markets.

 

Biodiesel:

In some countries such as Germany, biodiesel is often used. Some other biofuels such as straight vegetable oil are also being used by some farmers.

 

Types of Tractors: 

The Tractor Types can be classified into 3 major divisions namely:

  • Type of Construction
  • Type of Drive
  • The Purpose for which the usage is done

The First type is Construction type and it is further divided into 2 types.

i) First type is the Tractor in which the driver can easily sit and drive the machine.

ii) The Second type is the Tractor in which the operator walks along side and it is also called as Walking Type Tractor.

The Second type depends upon the type of drives i.e.

  • Track Type
  • Wheel Type

Tracked Type has Half Track and Full track types of tractors.

Wheel type is subdivided into: (i) 2 Wheeler or Two Wheeled (ii) Three Wheeler or 3 Wheeled and (iii) Four Wheeler types of tractors.

 

Track Type Tractors:

In these types of Tractors, instead of wheels one track is fitted on either side. This track get drive from the sprocket run by real axle shaft. To steer the Tractor, there is no steering gear fitted. Here, the machine is steered by applying brakes to one side of the track while the other track is in motion.

 

Half Track Type:

In these types of Tractors, a small track chain is fitted at the rear end only while tyres are fitted at the front axle. Track Type Tractors are generally used for reclaiming barren lands and are not much used for Agricultural tasks.

These machines are fitted with tracks in such a way that the contact area with ground is larger and facilitates in increased traction power. These machines are very useful in dams and in areas where earth moving tasks are required.

 

Wheel Type Tractors:

Their primary usage is in Agricultural tasks. They have fast running speed and the fitted tyres are able to absorb certain amount of field shock too.

The domain of use for these machines can be classified into small farms, hilly regions and for general gardening purpose.

 

Three Wheel or Tricycle Type:

Three Wheeled Tractors were very popular 20 years back but now they have been replaced by Four Wheelers. They had single or dual wheel fitted at front end and were considered apt for moving around shorter turns. The Types of Tractors in third classification depend upon the purpose for which they are used. They are further divided into broad categories listed below:

  • Utility Tractors.
  • Row Crop Tractor.
  • Orchard Type.
  • Industrial Tractor.
  • Garden Tractor.
  • Rotary Tillers.
  • Implement Carrier.
  • Earth Moving Tractors.

 

Utility Tractor is general purpose machine and is designed for ploughing and driving any other equipment through its drive and is considered good for such farms where farmer cannot afford more machines to perform specific jobs.

 

Row Crop Tractor:

This is an all round machine and is designed in such a way that it meets all the Agricultural demands like Ploughing, Harrowing, Levelling, Pulling Seed Drills, Weed Control, running different machines like Water Pumps, Threshers using belt pulley.

  • They have the below listed attributes.

  • They have greater ground clearance.

  • They have good row spacing provision.

  • They are easy to steer and can nicely take shorter turns.

  • These machines are user friendly and are easy to drive.

  • The attachment and detachment of Agricultural Implements is a quick and easy process with these machines.

  • There is a provision for power take off drive too.

  • A power lift is provided for heavy lifting or for lowering agricultural implements.

 

Orchard Type:

These special type Farm machines are only used in Orchards. These Tractors have big height so that while sitting on the Tractor the Driver can easily pluck the fruits or the trees can easily be trimmed. There is no part of this machine outside the surface and this allows easy passage in between the trees.

 

Industrial Type:

The Industrial Type machines are also called as Tuggers. They are useful in pulling loads and are fitted with crane boom for easy lifting of loads.

 

Garden Type:

These machines fall in the power range of 1 to 10 HP  and have very small construction size. They are mostly used for Grass Cutting or for making Flower Beds in the garden. The wheels fitted to such machines are having the size of a Scooter and have a thicker depth.

 

Rotary Tillers:

They fall under the category of Walking Type Tractors and are used in small fields or on hills where fields are smaller in size and are at different height levels. Here, Ordinary equipment cannot work efficiently. Blades are fitted to the tillers for the purpose of preparing seed beds efficiently by pulverizing the content of soil.

Implement Carrier: In these types of Tractors, there is an extended chassis frame between the front and rear tyres where all the implements like Seed Drills, Fertilizer, Drill, Duster, Sprayer, Rotary Sweeper, Loader, and platforms can be easily mounted.

 

Earth Moving Tractors:

These Farm Machines are heavy in weight and quite strong. They are available in both track and tyre type varieties. Their primary usage is for doing earth moving work on dams, quarries and different types of constructional works.

Tractor Agriculture leaves no stone unturned to showcase tightly knit information on relevant topics. These different types of tractors will give you a better idea of different machines that are being used worldwide.
