How to Identify Your Minneapolis-Moline Tractor
Model name, series, configuration, and serial number
Minneapolis-Moline tractors carry a few overlapping labels, and mixing them up is the most common reason people get stuck:
- Series / family — the platform, such as the U, Z, G, or R series.
- Model / configuration — how that platform was built. The U family, for example, was sold in several configurations, each with its own documented model page.
- Plate designation — the text actually stamped on your tractor’s plate. Sometimes it matches the configuration; sometimes it shows only a base letter.
- Serial number — the production number on the plate. It tells us the production-year range through documented records, but on its own it often does not pin down a single model.
You don’t need to know which is which before you start — enter the serial number and the tool does the matching.
When the plate shows only a base letter
If your plate shows just a base letter (for example “U”), that is a valid, correct designation — Minneapolis-Moline stamped some plates that way. The specific configuration is worked out from the serial number and the build, and any such conclusion is clearly labeled as inferred rather than presented as a fact printed on the plate. We never quietly relabel what your plate says.
Where to find the serial number
The identification plate’s location varies by model and production period, so follow the documentation for your specific model whenever available. On the U series, for example, the serial is documented on the transmission/gear case (right side) rather than on a separate nameplate. Clean off grease or paint and read it square-on. Where our records hold a documented plate location for your model, it is shown alongside your result.
Serial-number formatting
Enter the number exactly as it appears — the tool reads the digits, so the following are all treated the same: 1106191, 1 106 191, 1-106-191, and 01106191 (leading zeros are fine). A short letter prefix or suffix, such as 420151S, is also fine. Please enter just one serial number rather than a sentence or several numbers.
What a match proves — and what it doesn’t
A verified match tells you which documented model and production-year range your serial falls within, with the source and confidence for that record.
It does not, by itself, prove a specific tractor’s complete identity, confirm that every installed component is original or correctly configured, or certify authenticity. Serial numbers were restamped, swapped, and re-rated over the decades — treat the result as a sourced guide and confirm against your own plate and parts book.
What to do when there’s no match
A “no match” means the number isn’t in our verified records yet — not that it is wrong or invalid. Re-check the reading (characters like O/0, I/1, S/5, and B/8 are easy to confuse), make sure you’re reading the tractor’s serial plate rather than an engine or casting number, try the full serial-number lookup, and consider adding your tractor to The MM Census so we can document it.
How to photograph your plate
- Fill the frame with the plate and shoot square-on, not at an angle.
- Side lighting makes stamped digits easier to read; avoid direct glare.
- Take one close-up and one wider shot showing where the plate sits.
- Wipe off grease, but don’t wire-brush a stamped number — you can lose digits.

How we source and rate results
Every serial range on MinnieMo is tied to a source and a confidence level, and where published records conflict we show them side by side instead of choosing a winner. Primary sources (such as the University of Nebraska Tractor Tests) outrank secondary ones, records still under review are never shown as verified matches, and where we are unsure we say so. A missing fact is better than a wrong one. See our Sources & Methodology.
Frequently asked questions
How do I identify my Minneapolis-Moline tractor?
Enter the serial number stamped on your tractor’s identification plate into the tool on this page. We check it against our documented, verified serial-number ranges and show the model and production-year range it falls within, along with the source and confidence for that record.
Where is the serial number on a Minneapolis-Moline tractor?
It varies by model and production period, so follow the documentation for your specific model whenever available. On the U series, for example, the serial is documented on the transmission/gear case (right side). Where we hold a documented plate location for your model, it is shown with your result.
What does a serial-number match prove?
A match identifies the documented model and production-year range for that number. It does not, by itself, confirm that every component currently on the tractor is original or correctly configured.
Why did my serial return more than one model?
Minneapolis-Moline did not use globally unique serial numbers, so the same number can fall within more than one model’s documented range. We show every documented match rather than guessing one.
Why was there no match for my serial?
It may mean the number was read incorrectly, the number is from another component such as the engine, the relevant range has not been verified yet, or our database does not yet cover it. A no-match is not a verdict that the number is invalid.
