ZTU
VerifiedThe Minneapolis-Moline ZTU was produced 1936–1948. 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.
Where sources disagree: for one or more years, TractorData and Old Iron Garage report slightly different boundary serials. Those rows are marked conflicting in the table below and show the issue rather than picking a side. Verify against the Floyd County factory ledger.
