Big Bud 747 is the worlds largest Farm Tractor. It was built in Havre, Montana USA in 1977 by Ron Harmon of the Northern Manufacturing Company. Big Bud 747 is 28½ feet long, 14 feet high, 21 feet wide and has a wheel base of 16 ½ feet; it weighs in at 45 tons with a full diesel and hydraulic oil tank. The total cost to make this kind of huge tractor was $300,000.
Big Bud 747 is 16 cylinder behemoth powered by a 24.1 litre Detroit V16 92Turbo engine delivering 900hp. It has six forward and one reverse gear driving all of its eight foot tall wheels. With hydraulic powered steering and air brakes, and a 1000 gallon diesel tank with a 150 gallon hydraulic reservoir tank, BigBud is big enough and has the endurance for any job. Big Bud 747 works at a rate of one acre every minute whilst motoring along at 8 mph.
The world’s Largest Farm Tractor was initially designed for the Rossi Brothers, cotton farmers in Bakersfield, California. The Rossi Brothers used the tractor for deep ripping. They owned and operated the BigBud 16-V747 for 11 years.
After leaving the cotton farm of the Rossi Brothers the Big Bud 747 found its way to Indlantic, Florida. The second owners, Willowbrook Farms, also used the tractor for deep ripping purposes. Few years later Willowbrook Farms stopped working by the Big Bud and left it to rest.
The Big Bud 747 Tractor was rebuilt and reconditioned at the end of 1990, after successfully working for many thousands of man hours. In 1997 the Big Bud found its way back home to Montana, where it is apparently still in use today, pulling a huge eighty foot wide plough. It is owned by The Williams Brothers of Big Sandy whose farm is in Chouteau County.
Robert Williams, the current owner of Big Bud said that the tractor has a potential of up to 1100 horsepower and it can handle the biggest equipment at the current setting, so there’s no advantage to burning more fuel and putting more stress on the drive-train. He also said they have daily visitors for this giant tractor.
