At the moment, almost every country in the world annually hosts an exhibition of agricultural machinery. One of the most significant for Russia was the exhibition of JSC "Petersburg Tractor Plant" in Moscow (2009), which showed the largest domestic tractor "Kirovets K-9520". But, despite its impressive dimensions and technical characteristics, it still does not surpass its American counterpart "BigBud-747" in quality, which has been considered the largest tractor in the world for more than 30 years.
What makes these giants special and unique?
Production history
The manufacture of this "giant" was carried out by the American millionaire inventor Ron Harmon, who then worked closely with the design bureau "Northern Manifacturing". In fact, Ron did not expect to create a new super-tractor that would be mass-produced on the assembly line. The "BigBud-747" was designed in a single copy for two brothers-agronomists Rossi, who cultivated cotton in Bakersfield, California in the 70s. To this day, the largest tractor in the world drives through the fields of America and for the entire period of its existence has not been put into mass production. What is most interesting, for 37 years not a single company in the world has developed a similar technique that would have similar dimensions and technical characteristics to the Big-Bud.
What is the largest tractor in the world capable of?
As it turned out, the power of this technique is enough to process about 400 hectares of soil per day. A huge 30-meter plow was attached to the tractor, which is capable of plowing the ground to a depth of 120 centimeters. Such performance cannot be boasted by any modern
Technical features of the American "BigBud-747"
Under the hood of the world hides a powerful 16-cylinder diesel engine with a capacity of 760 horsepower.
The company "Detroit Diesel" was engaged in the development of this unit. Naturally, the appetite of such a giant was immodest. The BigBud-747 consumed about 65 liters of diesel fuel per minute. But, despite everything, it was equipped with a very small fuel tank (only 567 liters). Thus, a full filling of the tractor was enough for only 8-10 minutes. The tractor is aggregated with a 6-speed gearbox. The brake system here, as on heavy trucks, is of the air type (on all wheels).
As for the dimensions, the "BigBud-747" simply amazes with its dimensions: the length is 8,200 millimeters, the width is 6,000 millimeters, and the height is 4200 millimeters. The equipped weight of the tractor is 45.5 tons.
It is worth saying that the tires for the "American" were developed individually by the Canadian company "United Tire Company". By the way, the tire diameter itself is 240 centimeters. Having received such large wheels and an engine, "BigBud-747" was instantly awarded the title of "The largest tractor in the world."
What's the fate of Big-Bud today?
11 years after using it, in 1988, the Rossi brothers decided to sell this equipment to Willowbrook Farms, which is located in Florida. For 9 years he was constantly engaged in loosening and plowing the soil.
And in 1997, "Big-Bud" passed into the hands of a new owner, and now he is in his small homeland, in the state of Montana. Having got to the new owner, he was slightly modernized and received a new diesel engine with a capacity of 900 horsepower. According to experts, its current cost is about 600 thousand dollars.
To this day, this tractor is in perfect working order and still works and loosens the soil of the fields.
Russian hero - "Kirovets K 9520"
Unlike its American counterpart, the largest tractor in Russia has a slightly less weak engine (516 "horses") and a more modern design. It is also worth noting a new modification of the old series "Kirovtsa" - "K-744R3 M1" with a 428 hp engine. with.
Both tractor models are equipped with the latest technology, and all components are manufactured by the world's leading manufacturers. Thus, the modernized K-744R3 is equipped with a MB OM 457 LA turbodiesel engine and a German axial piston hydraulic system from Bosch. According to the manufacturer, the K-9520 and K-744R3 M1 models have high performance, power, ease of use and modern appearance (see photo).
The largest tractor in Russia, the K-9520 series, is the latest development of the Kirovsky plant, which has inherited all the best features of its predecessors: a reliable design, a powerful and economical engine. Indeed, over the past few years, the pace of development of domestic technology has been so high that it is safe to say that Russian tractors will be leading in the entire world market in the next 5-10 years.
Conclusion
So, we examined the technical characteristics of the largest tractor in the world of American origin "Big Bud-747" and the features of the new Russian "hero" "Kirovets K-9520".
The creation of huge pieces of equipment is not required for the sake of striving to break a record. Their creation is in demand due to the complication of production tasks, as well as increased requirements for work results. This is why special tractors are much larger than conventional trucks. The size limitation for them is only the existing framework of scientific and technological progress, as well as the production task. In this article we will tell you about the largest tractor in the world.
First place - Komatsu D575A (Japan)
The largest tractor in the world at the time of this writing is this crawler bulldozer. The car was created in 1980, but it was not mass-produced until a decade later.

The tractor is a faithful assistant to a person in many areas of economic activity.
The very word "tractor" is associated with strength, power and endurance! Today we will tell you about the largest tractors in the world today.
The largest tractor in the USSR
During the Soviet era, a huge industrial crawler tractor was created, which earned the attention of the Guinness Book of Records. We are talking about the T-800 bulldozer. It is recognized as the most productive, largest and most powerful in the world.
The giant's length is twelve meters forty centimeters, its height is almost five meters. The mass of the unit is also serious, it is one hundred and six tons. The engine of the bulldozer is "BelAZ" with an intercooler and gas turbine supercharging. Its speed is insignificant - it moves forward at a speed slightly greater than ten kilometers, and backward at a speed of fourteen kilometers per hour.
This largest bulldozer with loosening and bulldozer equipment was built by the Chelyabinsk Tractor Plant. The largest bulldozer in the Soviet Union was produced in Chelyabinsk The largest bulldozer in the Soviet Union was produced in Chelyabinsk.
Initially, as planned by the developers, the tractor was supposed to become an assistant when working with frozen heavy soils and rocks, where explosives are powerless. It was supposed to be useful for large-scale excavation work during road construction. With such an assistant, drilling and blasting is not required, since the bulldozer is able to tear the rock with its weight and fang.
The T-800 fully demonstrated its capabilities during the construction of the South Ural nuclear power plant, as well as during the reconstruction of Magnitka. After labor baptism, the giant bulldozer began to be used where other equipment turned out to be powerless.
The most powerful tractors in history
The tractor is an irreplaceable assistant in many fields of activity. One of the most powerful tractors was created in America in the state of Montana. Its name is "Big Bad", which can be translated as "Big friend".
Who was involved in the design is unknown, but several adventurers developed this huge tractor. The team was led by Ron Harmonn. The width of the tractor is six meters forty centimeters, the height is more than four meters, and the length is eight meters.
The engine power is nine hundred horsepower, and the travel speed is seven miles per hour. The weight of the Big Friend is fifty-two tons. The plow length of this tractor is twenty-five meters, which allows you to cope with work on plantations of any size without much difficulty.
A powerful tractor is the TERRION ATM 7360, manufactured at the St. Petersburg Tractor Plant. It has a capacity of three hundred and sixty horsepower. One of the most popular large tractors in Europe is the Fendt 936 Vario. It is produced by the German company AGCO Corporation. The power of the car varies from three hundred and fifty-five to five hundred horsepower, depending on the engine firmware.
A tractor with a rated power of three hundred and seventy horsepower is produced by Great Britain. Its name is Massey Ferguson MF 8690. The Dutch New Holland T9000 tractor is equipped with a 15-liter engine. Its capacity is five hundred thirty-five "horses". Germany is engaged in the production of Claas Xerion 4500. The power of this tractor is four hundred and eighty-three "horses".
Huge units are manufactured in America by John Deere. One of the largest giant tractors is called John Deere 8345R and 8360R with a capacity of up to three hundred and sixty horsepower, as well as a John Deere 9R series with a capacity of five hundred and sixty "horses". It is known that John Deere machinery works on sixty percent of all agricultural land on the planet.
One thousand one hundred and fifty horsepower - this is the power of the engine of the Super Dozer bulldozer. Its full name is KOMATSU D575A-3 SD. The length of the car fell slightly short of twelve meters. Another powerful machine is the KOMATSU D475A-5 SD, with a capacity of eight hundred and ninety horsepower. There is a bulldozer with a capacity of eight hundred and fifty "horses" - this is the CATERPILLAR D11R / D11R CD.
The largest tractor in the world
A lot of powerful large-sized tractors have been produced. But among them is recognized as the largest in the world. We are talking about a bulldozer that has never been used - this is an ACCO dozer with a capacity of one thousand three hundred horsepower. It was designed by the Italian company ACCO for Libya in the early eighties. The bulldozer was supposed to help in the development of new territories.
In those years, Gaddafi, who was the customer of this giant, was accused of international terrorism, which is why the UN sanctioned trade embargoes for Libya. As a result, ACCO dozer remained in Italy. There he is to this day.
A large tractor is considered to be an American-made "Big Bad". Its full name is Big Bad 747. The giant was built in 1977 and was intended to work on cotton plantations. He can cultivate an acre of land in a minute.
We remind you that you can buy a tractor in Tashkent in the company website, both in leasing and by transfer.
The company implements the websitetractors from various manufacturers.
In Russia. The tractor belongs to the 6th traction class, and is capable of performing the entire range of agricultural operations on any type of soil and in the most difficult conditions. Cars of this class are not in great demand, but in some climatic conditions they are the best option. Ruslan has been produced at the Cheboksary plant of JSC Promtractor since 2008.

The special equipment plant ZST is also a young production company, created on the basis of one of the branches of the former Kirovsky Plant. The ZST trademark was registered in 2011 and inherited the traditions of Soviet engineering. K-714 Petra is very similar to the legendary Kirovets K-700, not only externally, but also internally. K-714 is as simple and maintainable as possible, is not picky about fuel quality and can operate in the most difficult conditions. The level of localization is also high. All models are equipped only with domestic engines and almost all units of Russian production. The model has 20 different modifications from a bulldozer to a front loader. It is due to the low price, high functionality and unpretentiousness that the K-714 has a steady demand in the domestic market.

Tractors for various purposes are universal human assistants. Large and powerful special equipment is produced by manufacturers in many countries. Such products can be divided into the following categories: the largest tractor in the world, and mini special equipment; the most expensive cars and the cheapest; the strongest and fastest; the coolest and most sophisticated.
Komatsu record holder
The largest and heaviest tractor is the Komatsu D575A. Its gigantic size is amazing.
This is a real giant. Monster parameters:
- Height - 488 centimeters.
- Length - 11.71 meters.
- Width - 739 centimeters.
- Weight - 131 tons.
This is no longer a simple agricultural technique, the machine moves rock with a volume of 70 m³ in one step. Equipped with a 1150 horsepower engine. These are the largest tractors in the world. For comparison, the T 800 tractor and its technical characteristics:
- Height - 477 centimeters.
- Width - 419 centimeters.
- Length - 794 centimeters.
- Working weight - 106 tons.
- Equipment weight - 29 tons.
- Engine power - 820 horsepower.
- Fuel tank capacity - 2050 liters.
The bulldozer is equipped with two types of tracks: for rocky soil and clayey. This is not the heaviest tractor in the world, however, it takes a worthy second place.
The most powerful tractors in the world are not always and everywhere in high demand. They are more often employed in quarrying than for agricultural purposes. Powerful machines are the best for efficiently moving large volumes of soil. The production of large-sized and powerful special equipment is motivated by the desire to increase labor productivity, and not by the desire to achieve records. After all, for a long time no one is surprised by the dimensions of mining dump trucks. If their dimensions are not limited by anything, then tractors are limited by many technical characteristics aimed at preserving the soil.
Expensive agricultural machinery
The Big Bud 747 is the most expensive tractor today, with a price tag of $ 1,130,000. Technical characteristics and parameters of the most expensive tractor in the world:
- Length - 880 cm.
- Width - 550 cm.
- Height - 420 cm.
- Weight - 45 tons.
- The diameter of the wheels is 240 cm.
- Engine power - 760 horsepower. This power is achieved thanks to sixteen cylinders.
- The working volume of the engine is 24.1 liters.
- Fuel tank capacity - 3800 liters.
The giant consumes an incredibly large volume of diesel fuel - 65 liters per minute.
Fastest and smallest
Today there are a lot of agricultural machines, however, the fastest tractor in the world is the modernized MTZ-80 model. During test trials, the tractor reached a speed of 120 km / h. Despite this, this speed is not the most extreme. The car was tested on snowy ice. The developers are confident that this model can move much faster.
In addition to huge monsters intended for quarrying, manufacturers offer small, but fairly productive agricultural machines. Today the smallest tractor in the world is "Bulat 120". Its overall dimensions are slightly larger than a walk-behind tractor. However, due to its four-wheel design, this model belongs to the category of mini-tractors.
Product specifications:
- Length - 214 cm.
- Width - 95 cm.
- Height - 1175 mm.
- The power of the single-cylinder diesel engine is 12 horsepower. This is enough for a wide variety of everyday tasks.
- Water cooling.
- The limiting frequency of rotation of the crankshaft is 2400 rpm.
- Six-speed transmission, not counting two reverse gears.
- The ground clearance is 18 cm.
- Fuel tank capacity - 5.5 liters.
- The maximum speed is 22 km / h.
- Weight 410 kg.
Attached equipment allows you to use the tractor as a loader. It is an indispensable tool for harvesting onions, beets and potatoes. This technical tool is successfully used in arable work, in the transportation of goods, as well as in the cleaning of territories. The smallest tractor has a fairly high maneuverability, which is especially appreciated on personal and summer cottages.
