Allis Chalmers entered the farm equipment industry in 1914, having been a manufacturer of parts since the early 1840s. After having entered into the farm equipment industry, Allis Chalmers became the company to keep an eye out for. Innovative and driven, Allis Chalmers quickly became known as being one of the largest and most diverse manufacturers in North America. 

In 1985, Allis Chalmers was forced to sell the farm equipment devision of the brand. Not shortly after, in 1988, the remaining manufacturing parts of the company were sold. Even so, Allis Chalmers maintained a local office in Milwaukee up through January of 1999.
