Minneapolis-Moline U-302
Verified
The Minneapolis-Moline U-302 (1964–1970) was the later utility tractor carrying the U name, including the U-302 Super.
Identification & configuration
The U-302 sits in the U lineage but in the 1960s utility class; see the U-series overview.
Factory paint
Per the MMCI paint records, the 1964–1965 U-302 wore Industrial Yellow sheet metal with a Dyna Brown powertrain and Yellow wheels; later U-302 Super tractors moved toward the all-Yellow scheme. See the full paint reference.
What to verify
- U-302 vs U-302 Super: confirm by year and serial (ranges below).
- Trim: the yellow/brown scheme is a useful originality check for the year.
