Allis-Chalmers was a prominent tractor manufacturer that operated from 1901 until 1985. Founded in Milwaukee, Wisconsin, the company initially specialized in manufacturing machinery for the milling and mining industries. However, it gained widespread recognition for its tractors, which were known for their reliability and innovation. Allis-Chalmers played a significant role in the agricultural sector, producing a variety of tractor models over the years, including the well-known WD and D17. The company's orange-colored tractors became iconic in the farming community. Unfortunately, financial challenges led to its eventual bankruptcy and acquisition by Deutz-Allis in 1985. Despite its closure, Allis-Chalmers tractors remain collectible and are cherished by tractor enthusiasts and collectors worldwide.
