Bought an Allis and want to identify the year? This guide will walk you through Allis-Chalmers serial number lookup and tell you what year your Allis-Chalmers is from. Let’s get started.
What Is Allis-Chalmers?
Allis-Chalmers was a major manufacturer of farming and industrial equipment in the United States. This company was headquartered in Milwaukee, Wisconsin, with a major tractor factory in nearby West Allis, a town named for the company. Its brand gained fame among consumers mostly from its farm equipment business’s orange tractors and silver combine harvesters. In the 1980s-1990s, a series of financial difficulties led to its dissolution. The farm equipment operations were sold to Klockner-Humboldt-Deutz of Germany. Tractor production continued under the Deutz-Allis name until 1989. Its successors are Allis-Chalmers Energy and AGCO.

How to Read the Allis Tractor Serial Number Table?
The Allis-Chalmers serial number tables nearly always show the first tractor built in each year. The other tractors for that year will have successively higher numbers. Your serial number should lie between two of the stated numbers.
Example serial number list:
| Model Year | Serial Number |
|---|---|
| 1943 | 64501 |
| 1944 | 65502 |
| 1945 | 70210 |
For example, if you have an Allis-Chalmers B tractor and the serial number plate displays 65432, the model year of your tractor is 1943, because it is after the first serial number for 1943 but before the first number for 1944. The table only shows the number from the first tractor built in each year. Unless you happen to have the first tractor off the production line, then your particular number will not be on the list. Your number will lie between two listed numbers.
