The most expensive tractor in the world. Tractors STEIGER and QUADTRAC - when the size does not matter. The largest in Europe

At the moment, almost every country in the world annually holds an exhibition One of the most iconic for Russia was the exhibition of ZAO Petersburg Tractor Plant in Moscow (2009), which featured the largest domestic tractor Kirovets K-9520. But, despite its impressive size and technical characteristics, it still does not exceed the quality of its American colleague "BigBud-747", which for more than 30 years is considered the largest tractor in the world.

Empty the basket by pulling the linkage drawer as a standard before the auxiliary wheels of the mower, signaling the filling of the basket. Unpleasant vibrations and vibrations of the machine impractical and tense lowering of the mower larger gap in the sled with low rear seat tram runs without a front bumper. The tractor is equipped with a mower with two mowers, which is triggered by a button on the dashboard, controlling the electromagnetic clutch. The machine is sturdy in the field, turning a very small radius.

When lowering the grass is the same as with one of the tested machines, you can choose the maximum speed and still very well cut and fill the basket. Cutting high grass at medium speed is also seamless, a wide central ejection tunnel does not get stuck, but the basket is full. With a basket well-worked, it easily shifts from the driver's seat with the help of a retractable lever. When driving and taxiing in uneven terrain the tractor is relatively quiet, does not jump and has a low level of vibration.

What are special and unique these giants?

History of production

The American millionaire inventor Ron Harmon was engaged in the manufacture of this "giant", who then closely cooperated with the design office "Northern Manifacturing". In fact, Ron did not expect to create a new super-tractor, which will be produced serially on the assembly line. "BigBud-747" was developed in a single copy for two brothers-agronomists Rossi, who in the 70's were engaged in the cultivation of cotton in the city of Bakersfield, California. To date, the largest tractor in the world goes to the fields of America and for the entire period of its existence has not been put into mass production. What is the most interesting, for 37 years yet no company in the world has developed such a technique that would have similar dimensions with the "Big-Bud" dimensions and technical characteristics.

We were also pleased with the processing of the shops. The case of vertical metal pins, front wheel bearings are designed with rolling bearings. The overall good level is illustrated by other details, such as a steel frame in front of a mask or a drain plug for engine oil.

Very good grinding and filling the basket even at higher speeds smooth ride on large wheels easy to empty basket electromagnetic clutch closing mower alarm complete basket rear hitch basic equipment metal shell vertical pins and roller bearings on the front wheels adjustment of engine life. At that time, his plow was of good quality. He was always and is the forerunner of the ownership of the products of Dir. He still remembers his unforgettable story: "I will never give my name to a product that does not have the best in me."

What is the world capable of?

As it turned out, the capacity of this equipment is enough to handle 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 up to 120 centimeters. Such a productivity can not boast of any modern agricultural machinery.

Speaking of the wonderful deck of deer, which was really necessary in the difficult conditions of America, it spread widely. Soon the buyers learned that the plows have excellent geometry, good eyes, they do not care, and they are very reliable. Ten years later, he transferred his workshop to Moline, Illinois, where the company uses a profitable area near the Mississippi River and where it still has its own soap. A huge development of the company takes place over a century, and the growth of agricultural mechanization requires the growth of an incredible production of internal combustion engines in combination with plows, tractors, combines and other machines.

Technical features of the American "BigBud-747"

Under the hood the largest tractor in the world hides a powerful 16-cylinder diesel engine with a capacity of 760 horsepower.

The development of this unit involved the company "Detroit Diesel". Naturally, the appetite of such a giant was immodest. In a minute "BigBud-747" spent about 65 liters of diesel fuel. But, despite all equipped with a very small fuel tank (only 567 liters). Thus, a full refueling of the tractor was sufficient for only 8-10 minutes. Aggregated tractor 6-speed gearbox. The braking system here, as well as on heavy-duty wagons, air type (on all wheels).

There are 34 production and development enterprises in the world, of which 16 are farmers, 9 are horticultural and communal machinery, 3 are construction equipment for builders, and 6 are for component production. We should not forget about two centralized spare parts stores. This company is the largest German manufacturer and exporter of tractors. Bruchsal produces more than 20 000 cabins a year. This is the central warehouse for Europe and Asia. France is also the land where John Deere settled and where he also produces cars.

This is primarily a technique for harvesting fruits. It focuses mainly on two places - in Illinois and Waterloo, Iowa. In Molina, sloping millions are grown on the American continent. In the following places, next to Waterloo, there are engines, hydraulic system and other accessories for tractors, skidders, as well as for construction equipment and others. In terms of current needs or perception of our agriculture, the American continent was interrupted, especially in terms of more expensive tractors.

As for the dimensions, "BigBud-747" simply amazes with its dimensions: the length is 8200 millimeters, the width is 6000 millimeters, the height is 4200 millimeters. The equipped weight of the tractor is 45.5 tons.

It should be said that tires for the "American" were developed individually by the Canadian company "United Tire Company". By the way, the diameter of the tires is equal to 240 centimeters. Having received such large wheels and engine, "BigBud-747" was instantly awarded the title "The biggest tractor in the world".

You can also reach us through the ocean. Of course, these outputs are rated for the rated engine speed, and the maximum output is up to 22 kW. Small sizes, but large, in terms of large community users, are small tractors and a whole collection of petty mechanization. In recent years, John Deere also built a large clay mill in Brazil. Construction machines are manufactured. Despite their compact size, they provide a high degree of safety and comfort even for a long working day.

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

11 years after its use, in 1988, the brothers Rossi decided to sell this technique to the farm "Willowbrook Farms", which is located in the state of Florida. For 9 years he constantly engaged in loosening and plowing the soil.

And in 1997 "Big-Bud" passed into the hands of the new owner, and now he is in his small homeland, in Montana. Having got to the new owner, it was slightly upgraded and got a new diesel engine with a capacity of 900 horsepower. According to experts, today's cost is about 600 thousand dollars.

Despite their small width, these tractors offer all the necessary functions, providing high performance and perfect driver comfort for maximum productivity. Another way to use them is to deploy in public services. These universal tractors can be equipped with complete communal equipment for summer and winter maintenance of roads, sidewalks or business districts.

All of them are equipped with a cabin with air conditioning, suspended on quiet blocks and charcoal filters. For the comfort of even larger drivers, the cabin is equipped with an elevated roof level. For customers who work in less difficult conditions and in small rooms, you can put a version without the front axle. But even from the farm these tractors will play an important role. For example, in the transport of slurry or manure, for silage and a number of other operations in which speed plays an important role. Two other top models extend the performance range to 113 hp.

Until today, this tractor is in absolute working condition and is still processing and loosening the soil of fields.

Russian hero - "Kirovets To 9520"

Unlike its American counterpart, the largest tractor in Russia has a slightly weaker engine (in 516 "horses") and a more modern design. Also worth noting is a new modification of the old Kirovtsa series - K-744R3 M1, with a 428-liter engine. from.

So, the modernized "K-744R3" is equipped with a turbo-diesel engine "MB OM 457 LA" and a German axial-piston hydraulic system from the company "Bosch". According to the manufacturer, the models "K-9520" and "K-744R3 M1" have high performance, power, are characterized by ease of operation and modern appearance (see photo).

Up to 3 mechanical switchboards and up to 2 mechanical central switchboards. The possibility of installing a joystick to control the front loader directly on the panel to the right. The side doors provide access from both sides - almost without locking by the shift control levers and the front loader on the right panel. Extra seat for passenger seats for easy access.

Two night front working lights and two rear adjustable lanterns or 4 working lights are available for night work. Work lights are protected under the roof. Due to its robust design, it is also suitable for other agricultural applications, such as growing vegetables and special crops.

The largest tractor in Russia, the K-9520 series is the latest development of the Kirov plant, which inherited all the best features of its predecessors: reliable construction, a powerful and economical motor. Indeed, over the past few years the pace of development of domestic equipment has been so high that it can be confidently said that Russian tractors will be leading in the entire world market in the next 5-10 years.

It can also be found in public services. Robust, solid cast iron block construction for agricultural applications. The capacity of the fuel tank is 90 liters for long days. Increase of torque up to 35% for high loads. Air filter with exhaust system. Reversing is located on the steering column = easy access and high productivity due to a change in direction without the need to raise the clutch pedal. The joystick on the external boards allows you to control two switches at the same time.

Versatility: central switch for external circuits for managing additional applications with joysticks on external boards for simultaneous control of two switches. During development, the emphasis was placed on the perspective and ergonomics of the loader and the entire tractor. Panoramic roof for excellent and convenient control of the front loader. Folding steering column and dashboard with pedal for quick customization.

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.


American farmers in the state of Carolina do not suffer from gigantomania, but to process their crops they use the biggest tractor   in the world - BigBud-747.

When boarding, there is a folding seat without restrictions. Air is distributed in the cabin through 10 exhalations, which are located on the front panel. Their new design is designed for versatility and high comfort. This type was mainly developed by the farmers themselves who were asked about the operational requirements of tractors involved in research and prototype testing. They constantly meet all the requirements of modern small and medium-sized farmers.

The sturdy construction of the cast iron block ensures durability for all agricultural applications. The capacity of the fuel tank is 155 liters for long days. High-performance cooling system = increased heat output by 30% and increased fan diameter from 480 to 520 mm. The number of external hydraulic circuits is 2 or 3 external hydraulic circuits, which can have up to 8 fast couplings. Cabin cab, which was designed for work pleasure. Perfect views from the driver's cab thanks to the panoramic roof panel for an ideal and easy handling of the front loader, comfortable driver's seat, easy tilt steering column and dashboard.

It was a long time ago when American colonists used the manual labor of involuntary slaves who worked the ground with a hoe. Technical progress developed by leaps and bounds and in 1977 the largest tractor in the world of analogues was constructed and built, which in this class is still not available. The tractor was named by the big name BigBud-747, the serial number of which, perhaps, hints at the Boeing-747, the serial production of which started a little earlier.

Their new design, finish and comfort move them to the very top of the class. Tractors are powerful universal tractors, suitable for farms with the production of plants and livestock with a number of innovative features. Automatic transmission at specified speeds.

The number of external hydraulic circuits - 2 or Hydraulic circuits can be equipped with a timer to improve performance. Less electronics, more mechanics predetermine these tractors for those who want a simpler option for daily work.

The cab comes with a reduced roof on request, for better portability. The strongest hydraulics in this category ensures that you pick up even the most sophisticated tools, and you will always have enough hydraulic oil. Extended service intervals guarantee low operating costs.

Video of the biggest tractor in the world

BigBud-747 - a tractor that exists in a single copy, still working on agricultural cotton fields in the state of Carolina, was designed by the American inventor and millionaire Ron Harmon, who lived in the same state. The design documentation was developed by the Northern Manifacturing Design Bureau, which took an active part in the development of this machine.

With a service interval of up to 600 hours, which are the longest in your class, you save your time and money. At the same time, they are characterized by low emissions. With power management, you can get up to 28 extra calories. Effective torque transmission.

The sorting between the two mechanical operating ranges is performed automatically with a double clutch. The double-clutch technology provides less loss of the hydrostatic branch due to the lower inclination of the hydrogenerator. The cabin is the largest in its class and provides a very good view. The ergonomic arrangement of all controls ensures efficient operation. Lifting power - more power for working with hydraulics.

Big Bud 747, was originally developed for the farmers of the Rossi brothers, who were engaged in the cultivation of cotton in the town of Bakersfield, California. Brothers Rossi used the biggest tractor   for deep plowing of soil. The tractor's power was enough to plow the soil with a 30-meter plow to a depth of up to 1.2 meters. For a day Big Bud 747 allowed to process up to 400 hectares. For 11 years, the Rossi brothers used the Big Bud tractor, then it was sold to the Willowbrook Farms farm, Florida, where it was also used for deep loosening of the soil.


The tractor was born with a 16-cylinder diesel engine produced by Detroit Diesel and 760 horsepower, instantly gaining the status of "the biggest tractor". The length of the Big Bud 747 tractor is 8.2 meters, width - 6 meters and height 4.2 meters.

Tires for the tractor were specially manufactured by United Tire Company of Canada, whose diameter is 2.4 meters.


In 1997, the biggest tractor, Big Bud 747, returned to his small homeland, Montana, in a place just 60 miles from where he was built. Having got to the new owner, the tractor was slightly upgraded and received a 900-horsepower power unit. At the moment, the cost of the tractor is estimated at $ 600,000.
