Minneapolis-Moline’s U series was the company’s full-size mainstay from the late 1930s into the 1960s. This overview maps the main models; each links to its own page with serial-number ranges.

Model Years Notes
UTU 1938–1955 Row-crop (universal), tricycle front
UTS 1948–1957 Standard-tread
UB 1953–1955 Updated U; offered in gas, LP-gas and diesel
U-302 1964–1970 Utility

How they line up

  • UTU vs UTS: the UTU is the tricycle-front row-crop (universal) U; the UTS is the standard-tread version.
  • UB (1953–1955): the updated U, offered across gas, LP-gas and diesel fuel systems.
  • U-302 (1964–1970): the later utility model carrying the U name.
