I ran across this interesting article about the Deutz-Allis 9170. It was one of the first tractors made by the newly formed Deutz-Allis Corp. after the buyout of the Allis-Chalmers agricultural line. As Allis-Chalmers struggled in the 1980s the company looked to sell divisions off to stay in the black. Unfortunately, the manufacture of the firm’s orange ag line, which had been strong in the past, was not spared from this. Deutz had no interest in continuing the innovation of Allis-Chalmers–they saw a vast dealership network in North America to sell their product. This article explains how well that worked out for them.

I use to find history about the different Allis plants on your old website. I like reading about the industrial history of this country. Are these articles on this site somewhere?
I changed website names a few years ago. All of my AC transferred. You can do a search in the search bar on here to find them. Thanks for following/reading.
