Minneapolis-Moline ZTS
Verified
The Minneapolis-Moline ZTS was produced 1937–1947. This page documents serial-number-by-year ranges for identification and dating, cross-checked against two published references that agree on the figures. It does not list horsepower, engine, or production specifications until each is confirmed against factory literature.
Serial-number location varies by model; always confirm the number against your own tractor and parts book before relying on it — Minneapolis-Moline serial numbers were re-stamped, swapped, and re-rated over the years, and were not unique across models.
