Allis-Chalmers farm tractors

The Allis-Chalmers Company was a major manufacturer of farming and industrial equipment in the United States for most of the Twentieth Century. Allis-Chalmers was headquartered in Milwuakee, Wisconsin with a major tractor factory in nearby West Allis (a town named for the company). Financial difficulties led to dissolution in 1985. The farm equipment operations were sold to Klockner-Humboldt-Deutz of Germany. Tractor production continued under the Deutz-Allis name until 1989, when management purchased the company to form AGCO.
