Overview of the largest tractors in the world. The largest tractor in the world Heavy tractors

Modern special equipment should increase the productive process and cope with a huge amount of work. It is for this reason that engineers create tractors and other machines with significant technological capabilities that are record-breaking in size. Special equipment of impressive size can cope with jobs that would take people years to complete. Huge mechanized means are simply necessary in agriculture, timber and metallurgical industries, in construction. Most big tractor in the world is used to perform work in quarries.

Komatsu D575A - the largest tractor on the planet

The most powerful machinery in the world has always been used to carry out the heavy work associated with the extraction of minerals in quarries. Machines that could cope with a huge amount of work could perform the most difficult tasks in the shortest possible time. Best of all in this regard, the world's largest tractor Komatsu D575A has proven itself. This crawler bulldozer was designed by Japanese engineers. The first tractor model was manufactured in 1981. It took about 10 years for research and development before the tractor began to be mass-produced.

The Komatsu D575A career monster strikes with gigantic dimensions:

• unit height - 4.88 m;
• length - 11.71 m;
• width - 7.39 m;
• weight - 131.350.

The tractor can move rock at a time, with a volume of about 70 cubic meters. It is equipped with a diesel engine, the power of which is 860 kW or 1150 horsepower. The Komatsu D575A bulldozer can be equipped with a larger blade, the use of which allows you to move up to 96 cubic meters of earth or other materials at a time.

The largest tractor is produced in the Japanese city of Osaka. At first, a prototype was made, on the basis of which a bulldozer was created suitable for mass production. Today, the Komatsu D575A tractor can be seen in huge quarries all over the world. Most units of this technique are used in the USA, Canada and Australia.

The plant in the Russian city of Chelyabinsk produces the world's second largest tractor, the T-800. This unit is the largest in Europe and is used for work in quarries or large-scale construction. To date, only 10 of these bulldozers have been produced. At the present time, the management of ChZT is looking for new orders for the manufacture of such powerful special equipment, which come from India, Tajikistan and other countries.

The T-800 bulldozer can really carry out huge amounts of work in the shortest possible time. But the problem lies in the low mobility of technology. To deliver the tractor to its destination, a special airliner is used, the flights on which are very expensive. It is impossible to deliver the bulldozer with other equipment because of its gigantic dimensions:

• height of the special vehicle - 4.25 m;
• length - 7.95 m;
• width - 4.19 m;
• weight - 103 tons.

The place of honor in the list of the largest tractors on the planet goes to the Big Bud 747. This special vehicle was created for work in agricultural land. The first model Big Bud 747 was designed and built for an agricultural enterprise. The tractor was demonstrated to the world in 1977. It caused a real sensation among connoisseurs of technology, since it was many times larger than previously built similar machines.

The Big Bud 747 tractor is manufactured at a plant in Le Havre, Montana, USA. The machine is used to strengthen fertile soils subject to destruction and for deep loosening of fields of a large area. Today, the tractor is found in huge agricultural enterprises around the world.

The Big Bud 747 tractor is not accidentally considered one of the largest in the world. Its dimensions are really impressive:

• machine length - 8.69 m;
• width - 6.35 m;
• height - 4.3 m;
• weight - 48 tons.

The Challenger MT975B also impresses with its size. This tractor is able to carry out huge amounts of agricultural work in the shortest possible time. It is quite a bit smaller than the Big Bud 747, but it is much more common in the fields. The production of the huge Challenger MT975B tractor is carried out by the American corporation Caterpillar. Its engineers supplied the special vehicle with an engine whose power is equal to 600 horsepower. The tractor can loosen the soil over a large area in a short time. Also, due to its significant weight, the machine is used to compact fertile soil layers that are threatened with destruction.

The tractor has become a very successful version among similar equipment that is mass-produced. Challenger MT975B can be seen on large plantations and fields in most countries of the world. The car can move at a maximum speed of up to 40 km / h, which makes its mobility quite good. Such a unit weighs more than 27 tons. The length of the tractor reaches 7.57 m, and the width is 5 m.

The top five largest tractors include the Case STX Steiger special vehicle. It is produced in the American city of Fargo, located in North Dakota. The first model of a tractor designed for agricultural work was so successful that it was immediately launched into mass production. Since 1986, the plant has built about 50 thousand units of such equipment.

A notable feature of Case STX Steiger tractors is that they can be either wheeled or tracked. Engineers came up with triangular tracks that are easy to install in place of the wheels. Tractors are supplied to the market in various configurations. They are equipped with engines of various capacities, ranging from 274 kW to 439 kW.

The Case STX Steiger tractor of any modification impresses with its huge size. It reaches a length of 7.6 m, and a width of 3 m. The car weighs 24 tons when wheels are installed on it. Installing caterpillars makes the car slightly heavier, the weight of which is 26.3 tons. The tractor can travel at a maximum speed of 30 km/h. From 758 to 1,138 liters of fuel can be poured into its fuel tank.

The construction of huge equipment is not caused by the desire for records, but by the desire to increase productivity and return on its work. Therefore, no one is surprised that the dimensions of mining dump trucks are many times larger than conventional trucks. The same applies to special and agricultural machinery.

For special equipment, only technological capabilities are a limitation, which is why the largest tractors in the world are used in mining and construction work. But the increase in agricultural units is limited by the need to preserve fertile soil from destruction.

However, in recent years, the gap between special equipment and agricultural machinery has been narrowing.

As evidenced by our selection of the largest tractors in the world.

Quarry King

The championship in the category of special equipment belongs to the Japanese tracked bulldozer Komatsu D575A. The model was first introduced in 1981, but mass production began only 10 years later. Then a bulldozer equipped with an 1150 hp engine. and 12.7 meters long, interested mining companies. This is not a career worker, but its dimensions are impressive.

The unit is equipped with a water-cooled engine with direct fuel injection and turbocharging. Thanks to a powerful engine and a blade 3.63 m high and 7.39 m wide, it is capable of moving rock with a volume of 70 cubic meters at a time. As an option, the Komatsu D575A can be equipped with a blade 5 meters high and 11.7 meters wide.

Largest in Europe

The Chelyabinsk T-800 became the largest tractor in Europe for a reason. Its dimensions are 12.4 m. The length and width are 4.2 m. The mass of the unit reaches 106 tons, 30% of which falls on attachments.

This car is driven by an 820 hp engine, equipped with an intercooler and a gas turbine cooler. The gearbox has 4 forward and 2 reverse gears.

The bulldozer is designed for mining or construction involving significant amounts of excavation. To date, only 10 cars have been produced.

The only one in its class

The American Big Bud 747 is considered the largest agricultural tractor in the world. At birth, the tractor received a 16-cylinder engine from Detroit Diese, capable of developing 760 hp, and after modernization in 1997, engine power increased to 900 hp .

The length of the tractor exceeds 8 m, the width is 6.3 m.

Especially for the tractor, exclusive tires with a diameter of 2.4 m were made. The weight with full equipment is 50 tons. It is used for deep plowing and is capable of processing 400 hectares per day with a 30 meter plow, with a plowing depth of 1.2 m. The tractor is equipped with a 6 + 1 gearbox and pneumatic brakes. Fuel consumption 65 gpm (246 lpm) at full load. Fuel capacity 567 liters in the hydraulic reservoir. The fuel tank is designed for 3785 liters diesel fuel.

Challenger MT975B - a serial production giant

The giant "Challenger MT975B" is the largest representative of the "MT900B" series produced by the agricultural division of the American corporation Caterpillar. It is a four-wheel drive articulated tractor equipped with an engine of more than 600 hp and an operating weight of 27 tons.

The tractor is only slightly smaller than the Big Bud 747, with a height of 8.2 meters and a width approaching 5 meters, thanks to which it managed to surpass its competitors from Case and become the largest mass-produced agricultural tractor in the world.

The unit is equipped with a 6-engine C18 ACERT certified to Tier III requirements.

The torque reserve is 42%, which allows the tractor to be used in all jobs requiring increased traction.

Standard equipment includes a Powershift 16/4 transmission, which is a version of the gearbox used on Caterpillar heavy duty vehicles.

STEIGER and QUADTRAC tractors - when size doesn't matter

If in terms of dimensions the Case IH Steiger 600 Qudtrac 600 tractors are inferior to the brainchild of Caterpillar, then in terms of engine power they have no equal.

The maximum power developed by these monsters is 670 hp. otherwise, these models are similar to each other almost like twin brothers.

Same 16/2 Powershift PS6 transmission, same variable displacement, pressure and flow compensated (PFC) hydraulic system. The only difference between them is that, due to the twin wheels, the Steiger 600 looks larger than its caterpillar counterpart.

John Deere 9RT - a classic with a modern twist

Crawler 9RT can be attributed to the largest tractors with a classic layout. As you can see in the video, the world's largest solid-frame tractor is not much inferior to its articulated-frame competitors. The PowerTech 13.5L Stage II engine develops 616 hp and is capable of running even on low-quality fuels without loss of power.

The tractor itself is equipped with a track leveling system and special drive wheels for improved traction. The unit is equipped with the AirCushion suspension system, which allows the tractor driver to feel comfortable even when traveling over rough terrain.

Video of the world's largest tractor on display.

Unfortunately, you can see the largest tractor in the world in operation only in photos and videos, of course, with the exception of serial samples. But even such an acquaintance allows us to imagine what power lies in these tractors.

The largest tractors in the world were created not for the sake of vanity, but to increase labor productivity. They work in extreme conditions, performing super-heavy work.

Big Bud-747 - the world's largest tractor

Big Bud-747 from USA leads the . It has been in service since 1977. His 16-cylinder diesel engine Detroit Diese provides a unit power of 900 liters. With. The dimensions are impressive: 8.8 × 6.3 × 4.2 m, its weight with equipment is 50 tons, the tank holds 3785 liters of fuel.

With a 25 m wide cultivator, the eight-wheeled monster processes 1 hectare in 2.5 minutes. He loosens the soil with a 30-meter plow, plunging it to a depth of more than a meter, regardless of the condition of the soil. It so happened that the largest tractor was made in a single copy. Despite its venerable age, the price of the Big Bad is kept near the $1.3 million mark.

The most powerful bulldozer in the world is the ACCO Dozer Caterpillar bulldozer, made in Italy in 1980. The length of the bulldozer is 12 m, the weight is 183 tons. It has 2 engines with a capacity of 675 hp each. With. each. The giant was never launched into series. In addition, ACCO Dozer did not reach its customer, so he never had to work.

Modern heavyweights

The world's best manufacturers of agricultural equipment are creating heavy universal units, which, although they could not surpass the Big Bud and ACCO Dozer, amaze with their large size and power. The parameters of some brands of tractors and bulldozers are presented in the table:

This is the latest modification of the Russian TERRION tractors, produced by Agrotekhmash CJSC in 2011. The unit has earned high praise from Russian farmers. Thanks to good traction, the tractor can easily cope with the lifting of fallow lands. It has an economical engine, reliability is ensured by components and mechanisms made in Germany and Italy. Compared to prices for foreign analogues, the cost of a tractor is almost a quarter lower.

Fendt 936 tractor Vario

• The latest transmission, which increased engine efficiency by 12%.
• Diesel fuel supply system common rail, providing its low consumption at high power.
• Improved hydraulic system for automatic control of the work of hinges depending on the relief and the depth of soil processing.

The Fendt 936 is characterized by reliability and agility, and so far there is no analogue in the world. It is adapted to perform any agricultural and transport work.

Model Massey Ferguson MF8600

The American heavy-weight tractor works in any difficult conditions, in various field works, and can be used as a bulldozer. Its benefits include the following:

• Heavy-duty diesel engine of the famous Finnish company AGCO SISU Power.
• Special gearbox with automatic speed control depending on the load.
• Tires made of durable exclusive rubber with a deep tread pattern that is difficult to damage.

Reduced emissions of harmful substances makes the machine environmentally friendly.

German Claas Xerion 4500

This model of a large tractor is produced by the largest German company Claas. A unique find of the inventors is the swivel cab (Variable Cab), which can be located in the middle, front or rear. This expands the functionality of the unit. Various functions are controlled by a joystick with 8 buttons.

Due to the fact that all wheels have the same size, the engine power is evenly converted into tractive effort, and the tractor weight is equally distributed on both axles. This ensures low pressure on the soil.

The birthplace of the New Holland tractor of the T9000 series is the USA. It is characterized by such unique engineering solutions:

• a large margin of torque of a diesel engine with gas turbine supercharging;
• powerful transmission;
• increased wheelbase;
• high performance hydraulics.

The giant is able to perform deep loosening and any heavy work on soil cultivation.

This bulldozer, the largest in Europe, was created at a tractor plant in Chelyabinsk and is listed in the Guinness Book of Records. Its length with attachments is greater than that of the world's largest tractor, and its height is only 50 cm less. The huge power of the bulldozer allows you to loosen the soil, which even explosives cannot cope with. Due to its impressive weight, it destroys any obstacles in its path.

Used in construction and mining industry. The Ural bulldozer can replace an excavator and vehicles (it digs and pushes the soil itself). A total of 10 tractors of this series were produced, the last one in 1999.

John Deere 8345R and John Deere 8360R

John Deere models 8345R and 8360R belong to the line of row-crop tractors. Engine power - 345 and 396 liters. With. respectively. They are very popular with farmers.

Deservedly considered the king of quarries, this Japanese caterpillar armored tractor is used in the mining industry. Its serial production began at the very end of the last century. With the help of a blade measuring 7.39 × 3.63 m, the bulldozer moves up to 70 m 3 of rock at a time.

Despite the power and impressive size, heavy tractors and bulldozers are easy to operate and have low noise in operation. Tightness, reduced vibration and noise insulation of the cab, the presence of an air conditioner and an on-board computer create all the conditions for a comfortable work of the driver.

At the moment, an exhibition of agricultural machinery is held annually in almost every country in the world. One of the most significant for Russia was the exhibition of CJSC "Petersburg Tractor Plant" in Moscow (2009), which showed the largest domestic tractor "Kirovets K-9520". But, despite their impressive size and specifications, he still does not surpass in quality his American counterpart "BigBud-747", which has been considered the largest tractor in the world for more than 30 years.

What is special and unique about these giants?

Production history

The manufacture of this "giant" was carried out by the American millionaire inventor Ron Harmon, who then closely collaborated with the design bureau "Northern Manifacturing". In fact, Ron did not expect to create a new super-tractor that would be mass-produced on an assembly line. "BigBud-747" was developed in a single copy for two agronomist brothers Rossi, who in the 70s were engaged in growing cotton in the city of Bakersfield (California). To this day, the largest tractor in the world drives through the fields of America and has not been put into mass production for the entire period of its existence. What is most interesting, for 37 years, no company in the world has developed such equipment that would have dimensions and technical characteristics similar to Big-Bud.

What is the largest tractor in the world capable of?

As it turned out, the power of this equipment is enough to process about 400 hectares of soil per day. A huge 30-meter plow clung to the tractor, which is capable of plowing the earth to a depth of 120 centimeters. None of the modern

Technical features of the American "BigBud-747"

Under the hood in the world hides a powerful 16-cylinder diesel engine with a capacity of 760 Horse power.

The development of this unit was carried out by Detroit Diesel. Naturally, the appetite of such a giant was immodest. In a minute "BigBud-747" consumed about 65 liters of diesel fuel. But in spite of everything equipped with a very small fuel tank(only 567 liters). Thus, the full refueling of the tractor was enough for only 8-10 minutes. The tractor is aggregated with a 6-speed gearbox. Brake system here, as on heavy trucks, air type (on all wheels).

As for the size, "BigBud-747" is simply striking in its dimensions: length is 8200 mm, width - 6000 mm, height - 4200 mm. The curb 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. With such large wheels and engine, "BigBud-747" instantly won the title of "The Biggest Tractor in the World."

What is the current fate of "Big-Bud"?

11 years after its use, in 1988, the Rossi brothers decided to sell this technique 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.

Until today, this tractor is in absolutely working condition and still processes 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 powerful engine (516 "horses") and a more modern design. It is also worth noting a new modification of the old Kirovets series - K-744R3 M1 with an 428 hp engine. With.

Both models of tractors are equipped with the latest technology, and all components are manufactured by the world's leading manufacturers. Thus, the upgraded 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 models "K-9520" and "K-744R3 M1" have high performance, power, are easy to operate and modern appearance(see photo).

The largest tractor in Russia of the K-9520 series is the latest development of the Kirov Plant, which 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 equipment has been so high that it can be said with confidence 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 tractor is a universal assistant to a person, which is used in many economic fields of activity. Large and powerful machines are produced by several countries of the world. What are the largest tractors?

The largest tractor in the USSR

The length of the giant 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. Bulldozer engine - "BelAZovsky" with an intercooler and gas turbine supercharging. Its speed is negligible - it moves forward at a speed of a little more than ten kilometers, and backwards at a speed of fourteen kilometers per hour. This largest bulldozer with loosening and bulldozer equipment was built by the Chelyabinsk Tractor Plant.

Initially, as conceived 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 high-volume earthmoving 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 showed its capabilities during the construction of the South Ural NPP, as well as during the reconstruction of Magnitogorsk. After labor baptism, the giant bulldozer began to be used where other equipment was powerless.

The most powerful tractors in history

A powerful tractor is TERRION ATM 7360, produced 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 machine varies from three hundred and fifty five to five hundred horsepower, depending on the engine firmware.

The tractor with a nominal power of three hundred and seventy horsepower is produced by Great Britain. Its name is Massey Ferguson MF 8690. The Dutch tractor New Holland T9000 is equipped with a fifteen-liter engine. Its power 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 produced in America by John Deere. One of the largest giant tractors is called the John Deere 8345R and 8360R with a capacity of up to three hundred and sixty horsepower, as well as the 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 - such is the power of the Super Dozer bulldozer engine. Its full name is KOMATSU D575A-3 SD. The length of the car was a little short of twelve meters. Another powerful machine is KOMATSU D475A-5 SD, the power is eight hundred and ninety horsepower. There is a bulldozer with a capacity of eight hundred and fifty "horses" - this is CATERPILLAR D11R / D11R CD.

The largest tractor in the world

In those years, Gaddafi, who was the customer of this giant, was accused of international terrorism, because of which the UN authorized 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 the "Big Bad" produced in America. Its full name is Big Bad 747. The giant was built in 1977 and was intended to work on cotton plantations. He can work an acre of land in a minute.

The most powerful armored tractor in the world is going to be created in Russia, while the T-800 bulldozer will be taken as the basis. This machine will be more powerful than the American Caterpillar D9 unit.

Big equipment is needed in big enterprises. For example, according to the site, the largest factory in the world is engaged in the production of aircraft.
