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 and built by Ron Harmon and the employees of his Northern Manufacturing Company, at a cost of $300,000. It was made for the Rossi Brothers, cotton farmers of Bakersfield or Old River, California. It was used there for eleven years; it was then purchased by Willowbrook Farms of Indialantic, Florida. Both farms used it for deep ripping.
After a period of disuse, it was purchased by Robert and Randy Williams, of Big Sandy, Montana, within 60 miles (97 km) of where it was built, in 1997. 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 at a speed up to 8 miles per hour (13 km/h).
