The first two Big Bud tractors out of the Havre, Montana plant were the 250-series and were purchased by Leonard M. Semenza of Semenza Farms in 1968 located between Fort Benton, Montana, and Chester, Montana on his 35,000 acre farm. The 747 tractor was originally designed by Wilbur Hensler[citation needed][3] and built by Ron Harmon and the employees of his Northern Manufacturing Company,[1][4] at a cost of $300,000.[4] It was made for the Rossi Brothers, cotton farmers of Bakersfield[1] or Old River, California.[4] It was used there for eleven years; it was then purchased by Willowbrook Farms of Indialantic, Florida. Both farms used it for deep ripping.

In 1997, after a period of disuse, it was purchased by Robert and Randy Williams,[5] of Big Sandy, Montana, within 60 miles (97 km) of where it was built. It was used on the Williams Brothers' farm in Chouteau County to pull an 80-foot (24 m) cultivator, covering 1.3 acres (0.53 ha) per minute[5] at a speed up to 8 miles per hour (13 km/h).

The United Tire Company of Canada, which made the tractor's custom 8-foot (2.4 m) tires, went bankrupt in 2000, partially contributing to the decision to stop using the tractor for regular work in July 2009,[4] and to move the Big Bud 747 to museums.[5]

After its work on the farm, it was displayed at the Heartland Acres Agribition Center in Independence, Iowa. In 2014, the Big Bud 747 was moved to the Heartland Museum in Clarion, Iowa, on indefinite loan from the Williams Brothers; the museum constructed a separate shed for the tractor in 2013.
