"Big Bud-747" is the largest tractor in the world. Photo and description

At the moment, almost every country in the world annually holds an exhibition of agricultural machinery. One of the most iconic for Russia was the exhibition of ZAO Petersburg Tractor Plant in Moscow (2009), at which the largest domestic tractor Kirovets K-9520 was shown. 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.

What are special and unique these giants?

Production history

The manufacture of this "giant" was engaged in the American inventor-millionaire Ron Harmon, who then closely cooperated with the design bureau "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 specifications.

What is the largest tractor in 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 was clinging 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.

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 this, the tractor was 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).

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 noted that the 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".

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

11 years after its use, in 1988, the brothers of 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 received a new diesel engine with a capacity of 900 horsepower. According to experts, today's cost is about 600 thousand dollars.

Until today, this tractor is in an absolutely 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 the new modification of the old Kirovtsa series - K-744R3 M1, with a 428-liter engine. from.

Both models of tractors are equipped with the latest technology, and all components are manufactured by the world's leading manufacturers. 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).

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: a reliable design, a powerful and economical motor. Indeed, over the past few years, the pace of development of domestic technology 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.

Conclusion

So, we reviewed 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.
