Minneapolis-Moline RTN
VerifiedProduction years: 1939–1951 (per TractorData).
The Minneapolis-Moline RTN is documented here with production years, manuals, and service references. Serial-number-by-year decoding for this exact variant is pending a verified source; the R/G series shared serial systems, so use the serial lookup and confirm by configuration. We do not assert horsepower or engine figures until confirmed against factory literature.
