Big Bud was a brand of articulated tractors built by the Northern Manufacturing Co., later renamed Big Bud Tractors, of Harve, Montana, USA. The Big Bud 747 tractor was for many years the biggest tractor in the World at 900 hp (670 kW).
The company has built a range of high horse power tractors for use in the prairies of America and the Canadian wheat belt. The company went bankrupt in the early 1980s and was bought up by the Meissner Brothers in 1985. Production slowed in the late 1980s due to the farming recession and increasing competition from mainstream manufactures building ever bigger tractors. The last Big Bud rolled off the line in 1992.
Five different Big Bud models were built and painted in what has come to be known as "Bafus Blue" for the Bob Bafus of the Oregon-based Bafus Farms. These are unique in livery, and some of them have been rebuilt or customized. There were also models built in what is known as "Iranian-Gold" which were sent to Iran.
Several manufactures now offer tractors of 500 hp (370 kW) in their line-up after buying up some of the specialists manufacturers.
Case IH parent Tenneco bought Steiger in 1986, Ford bought Versatile in 1987, and John Deere put Wagner out of business after a contract deal that ended with Wagner no longer being about to sell tractors as a competitor during the late 60s and early 70s. Ford then sold out the tractor business to Fiat which then operated the agri business under the New Holland brand in 1993. Fiat then later bought out Case IH & merged it with New Holland becoming CNH Global. CNH had to divest Versatile and McCormick Tractors due to competition restrictions, as they also owned Steiger. Versatile was sold to Buhler Industries Inc. in 2000.
Fendt is testing a 6-wd tractor of a reputed 540 hp+ rating.
Challenger is a 'new' entry in the sector taking on the Caterpillar Challenger Tractor range when Caterpillar Inc. decided to exit the agricultural sector & divested its range of rubber tracked Crawler tractors that revolutionize the Ag crawler market in the early 1980s.

- Main article: BIG Bud 747
The biggest Big Bud ever built is Big Bud 747. It was built in 1977 for deep plowing (UK spelling; ploughing ) on a cotton farm. The Rossi Bros Cotton Farms in Bakerfield, California had the tractor custom built at a cost of $300,000 in 1977. The tractor works at the impressive rate of 1 acre every minute whilst crossing the fields at 8 mph
The tractor is fitted with a 24.1 litre Detroit Diesel 16V92T engine that produces 900 hp. This immense power is transmitted to the wheels by a 6F + 1R Gearbox. The Tyres are a massive 8 ft tall. The tractor can potentially be opened up to 1100 hp by replacing the unit fuel injectors with higher flow models. Fuel is carried in a huge 1000 gallon (US) tank with a 150 gallon hydraulic reservoir for the steering and implement control system.
Big Bud 747 is;
- 28½ feet long,
- 14 feet high,
- 21 feet wide
- 16 feet wheel base
