Minneapolis-Moline U Series

Introduced in 1938, the Minneapolis-Moline U was the company’s mid-to-full-size workhorse of the Prairie Gold era — and the platform behind some of MM’s most sought-after tractors. Like most Minneapolis-Moline models, the U was sold in body-style configurations rather than as a single bare “U.” Here’s how the family fits together — each links to its full documented page with serial numbers, specifications, paint, and parts.

The U-series configurations

• UTU — U Tractor Universal: the adjustable row-crop (tricycle / wide-front) version, and the most common U.
• UTS — U Tractor Standard: the fixed-tread “wheatland” version built for small-grain country.
• UTI / UTI-M — U Tractor Industrial.
• UDLX “Comfortractor” — the 1938 enclosed-cab deluxe U, now one of the most collectible American tractors ever built.
• UB — the updated, more-powerful U introduced in 1953 (UB Special / Super).
• U-302 — the later U-series utility tractor (1964).

Minneapolis-Moline marketed the U in these configurations; it did not sell a separate base “U” tractor. Always confirm a specific tractor’s identity by its serial number.
