Minneapolis-Moline M-670 / M-670 Super
Verified
The Minneapolis-Moline M-670 (and M-670 Super) was the longest-lived of MM’s numbered M-series tractors, built 1964–1970.
Identification & configuration
The M-670 was part of the early-to-mid-1960s M line; see the M-series overview. The M-670 Super continued later in the decade.
Factory paint
Per the MMCI paint records, the M-670 wore Industrial Yellow sheet metal with a Dyna Brown powertrain and Yellow/Silver wheels (1964–1965); later M-670 Super tractors moved to an all-Yellow scheme. See the full paint reference.
What to verify
- 670 vs 670 Super: confirm which you have via the year and serial (ranges below).
- Fuel system & trim: verify configuration and check the yellow/brown scheme against the year.
