At the moment, virtually every country in the world every year an exhibition of agricultural machinery.One of the most significant for Russia was the exhibition of JSC "Petersburg tractor factory" in Moscow (2009), which was shown to the largest domestic tractor "Kirovets K-9520."But, despite its impressive size and specifications, it is still not superior to its American counterpart "BigBud-747", which is more than 30 years, is the largest tractor in the world.
What is special and unique, these giants?
production history
manufacture of the "giant" was engaged in the American millionaire inventor Ron Harmon, who then work closely with the design office "Northern Manifacturing".In fact, Ron did not expect to create a new super-tractor, which will be produced in series on the line."BigBud-747" has been designed in a single copy for two brothers agronomists Rossi, who in the '70s were engaged in cultivation of cotton in Bakersfield (CA).By far the largest tractor in the world goes through the fields of America and for the whole period of its existence has not been put into mass production.What is most interesting, for 37 years, yet no company in the world has developed such technology, which would have a similar "Big-Bud" dimensions and specifications.
was capable biggest tractor in the world?
As it turned out, the power of this technique enough to ensure that the day to process about 400 hectares of soil.I clung to the tractor huge 30-meter plow, which is able to cultivate the land to a depth of 120 centimeters.Such performance can not boast of any modern farm equipment.
Technical features of the American "BigBud-747"
Under the hood is the largest tractor in the world, hides a powerful 16-cylinder diesel engine rated at 760 horsepower.The development of the unit was engaged in company "Detroit Diesel".Naturally, such a giant appetite was indiscreet.At the moment "BigBud-747" expended about 65 liters of diesel fuel.But despite all this, the tractor is equipped with a very small fuel tank (total 567 liters).Thus, complete filling the tractor just enough for 8-10 minutes.Aggregated tractor 6-speed gearbox.Brake system here, as in the heavy wagons, aircraft type (all round).
As for size, the "BigBud-747" is striking for its dimensions: length is 8200 mm, width - 6000 mm, height - 4200 millimeters.The curb weight of the tractor is 45.5 tons.
It is said that the tires for "American" were developed individually by the Canadian company "United Tire Company".Incidentally, the diameter of the tire is 240 centimeters.Having such a large wheel and the engine, "BigBud-747" immediately awarded the title "The biggest tractor in the world."
What is the current fate of the "Big-Bud"?
11 years after its use, in 1988, the brothers Rossi decided to sell the farm this technique "Willowbrook Farms", which is located in Florida.For 9 years he was constantly engaged in plowing and loosening the soil.In 1997, "Big-Bud" has passed into the hands of a new owner, and now he is on his native land in Montana.After falling to a new host, it was slightly modernized and received new diesel engine with 900 horsepower.According to experts, today the cost of it is about 600 thousand dollars.
Until today, the tractor is in proper operating condition and still handles and loosens the soil fields.
Russian hero - "Kirovets K 9520»
Unlike its American counterpart biggest tractor in Russia has slightly less weak engine (516 "horses") and a more modern design.Also worth noting is a new modification of the old series "Kirov workers" - "K-744R3 M1" with engine capacity of 428 liters.from.
Both tractors are equipped with the latest technology, and all components are manufactured by leading world producers.So, the upgraded "K-744R3" equipped with turbo diesel engine «MB OM 457 LA» and German axial piston hydraulic system from the company «Bosch».According to the manufacturer, the model of "K-9520" and "K-744R3 M1" have a high performance, power, are easy to operate and modern in appearance (see. Photo).
biggest tractor in the Russian series "K-9520" is the latest development of the Kirov plant, which has inherited all the best features of its predecessors: robust design, powerful and economical engine.Indeed, in recent years the pace of development of domestic appliances were so high that we can confidently say that Russian tractors are leading the whole world market in the next 5-10 years.
Conclusion We have examined the technical characteristics of the largest tractor in the world of American origin "Big Bud-747" and features the new Russian "hero" "Kirovets K-9520."
