Who Big Bud was
Big Bud built the biggest tractors in American farming. Founded in Havre, Montana in 1968, the company made its name on scale alone — articulated four-wheel-drive machines engineered to pull the widest implements across the largest dryland acreages, at a time when most tractors were a tenth their size.
Roughly 500 tractors were built before production ended in 1991, and the marque is best known for the one-off 16V-747 of 1977 — still widely cited as the largest farm tractor ever made. That single-minded focus is why the brand reads as an outlier in every power chart: Big Bud never built a small tractor.
