Allis-Chalmers first entered the manufacturing business as E.P. Allis of Milwaukee in the 1840s making waterwheel, sawmill and grindstones. They soon became a major manufacturer of steam engines and industrial equipment after merging with other firms.
Allis-Chalmers was very active during war time entering into the farm equipment business in 1914. The company would also play a major part as a manufacturer in the World War II building pumps for uranium separation as part of the Manhattan Project and building electric motors for U.S. Navy submarines. Allis-Chalmers also built triple expansion marine steam engines for Liberty ships.

The company began to struggle in the 1980s There was a climate of rapid economic change. They were
forced to sell its farm equipment division to K-H-D (Klöckner-Humboldt-Deutz) AG of Germany in 1985 and was renamed Deutz-Allis and the tractors were sold under the AGCO-Allis name.
Briggs & Stratton announced in August, 2008, that it would sell lawn tractors under the Allis-Chalmers brand name.
