A Brief History of the Big Bud Tractor

It was in 1968 that the Big Bud tractor made its debut, with the first two models bought by Leonard M. Semenza. It was designed by Wilbur Hensler and built by Ron Harmon and his Northern Manufacturing Company employees. Although it came out with only the 250-series, this impressive machine soon revolutionized farming with its 747 tractors used for deep ripping through 35,000 acres of land owned by the Rossi Brothers in Bakersfield/Old River, California, and Willowbrook Farms in Florida.

After falling into disuse, two brothers from Big Sandy, Montana – Robert and Randy Williams – made a wise decision when they purchased this remarkable machine in 1997. After integrating the Big Bud 747 farming tractor into their farm in Chouteau County, the Williams Brothers were thrilled with its capabilities. It could pull an 80-foot cultivator at speeds of 8 mph, making it able to cover 1.3 acres per minute! This fantastic technology revolutionized farming in this area and changed how farmers approached their work.

In July 2009, the Big Bud 747 retired from regular work due to a combination of circumstances, including the United Tire Company of Canada’s bankruptcy in 2000.

We are very happy to see the return of the Big Bud 747 Farming Tractor! It has been under the ownership of the Williams brothers of Big Sandy, Montana, for some time before being retired and placed on display at one˙ Museum in Clarion, Iowa. Then, on Oct 10, 2020, this massive machine returned to its home state – where it all began. What an incredible and inspiring story – something we should all reflect on as a reminder to never give up!
