Minneapolis-Moline RTS
Verified
The Minneapolis-Moline RTS was produced 1939–1954 (1939–1947 ranges documented here). 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 numbers were stamped on the right side of the transmission case; 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.
