Allis-Chalmers Crawlers: An Impressive Track Record

Tracing the history of the Allis-Chalmers crawler and its parent companies.

The Allis-Chalmers HD-11 diesel crawler is shown in this 1957 photo with a hydraulic dozer blade. This mid-sized crawler was built from 1955 to 1970, and was one of the first to introduce the 6-cylinder, 4-cycle Allis-Chalmers/Buda engine.
