Allis-Chalmers Crawlers: An Impressive Track Record

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

The flagship of the Allis-Chalmers crawler fleet when Allis-Chalmers acquired the Monarch line in 1928, the Model F (or 75) was an impressive machine. An improved version with increased engine displacement appeared in 1929. It had a 60-gallon fuel tank and could use it all in a day’s work.
