Big Bud Farm tractors

Big Bud Tractors Inc. was born out of the Wagner tractor dealership in Havre, Montana in 1961. Big Bud manufactured heavy-duty high horsepower tractors with industrial engines fitted to custom-built frames. The company developed a number of innovations for heavy duty tractors, including tilt cabins and a skid system for engine removal. The company was purchased by Messner Brothers in 1985. Production slowed in the late 1980s and the last Big Bud rolled off the line in 1992.
