The Big Bud 747 or 16V-747 Big Bud is an agricultural tractor . It was built in 1977 as a one-off production in Havre in the US state of Montana and, according to its builders, is considered the "world's largest tractor" with its engine output of 1100 hp (820 kW). Measured by the parameters, it is about twice as large as the largest series tractors.
Manufacturer
When the business partners Wilbur Hensler and Bud Nelson lost their license to trade in the tractors of the Wagner Tractor Company ("FWD Wagner"), which were very popular at the time , they switched to the self-construction of agricultural tractors. In the same year a predecessor of the Big Bud 747 ("250 series") left the workshop and was sold to the farmer Leonard M. Semenza (Semenza Farms, 14,164 hectares , near Fort Benton ).
Priced at 300,000 US dollars took over in 1975 the 27-year-old Ron Harmon and his staff of the Northern Manufacturing Company the company. Bud Nelson, who was mostly called "Big Bud" because of his stature, stayed with the company for another six months. The company was renamed "Big Bud Equipment" and produced 80 to 100 tractors up to 525 hp (391 kW) per year (in 1980 and 1981 also tractors with 650 hp (485 kW) engine power), which were also sold to Australia, were sold to the Philippines and Iran.
The manufacturer ran into financial difficulties in 1980 because pre-ordered (and paid) tractors had severe transmission problems and the manufacturer of the transmission ("Twin Disc" from Wisconsin ) did not know how to remedy the situation. Big Bud Equipment was taken over in 1985 by the Meissner brothers' tractor company. Towards the end of the decade, tractor production slackened as a result of the agricultural recession and the growing competition from the large series manufacturers, who meanwhile also produced large tractors, also beyond 600 hp (447 kW). The last Big Bud, a model in the 450 hp series, rolled out of the production hall in 1992.
Big Bud 747, the world's largest tractor
In 1977 the Rossi brothers , cotton farmers from Bakersfield , California , ordered a particularly large tractor from Big Bud Equipment. The Big Bud 16V-747, the world's largest tractor, was built in just six months. Initially, it was delivered with an engine output of 760 hp (567 kW), but received an increase in output to 1100 hp (820 kW) in the subsequent years of its operation.
His owners who for the tractor US $ 300,000 paid (this would now around 1.3 million US dollars , respectively), it took 11 years, he has been to the Willow Brook Farm in Indialantic ( Florida sold). Both farms used the heavy tractor for subsoiling . After a period of non-use, it was bought in 1997 by Robert and Randy Williams from the village of Big Sandy, Montana. On the Williams Brothers farm in Chouteau County it was used to pull a 24 m wide cultivator . At a speed of just under 13 km / h he could work half a hectare per minute.
The giant tires were custom-made by the United Tire Company of Canada , which went bankrupt at the turn of the millennium. This contributed to the decision made in July 2009 not to continue using the tractor and to give it to a museum on permanent loan.
Today it can be viewed at the Heartland Acres Agribition Center in Independence , Iowa . An additional hall was specially built for this purpose.
