About Haas
Haas tractors were built after World War II by Metal Parts Corporation in Racine, Wisconsin. Ed Haas’s foundry business dated to 1939, and tractors continued into the early 1950s.

The machinery line was part of a broader metal-parts operation. The reviewed history does not establish that the foundry closed when tractors stopped, so the two activities are not assigned the same end date.
