Minneapolis-Moline Buyer Guides

What to know before buying or selling a Minneapolis-Moline — identification, what to inspect, and how to weigh value.

• Identification GuidesTell confusing models apart — ZA vs ZB, 5 Star vs M-5, RTU vs RTS — with sourced comparisons.
• Verify Before You BuyDecode the serial to confirm the model and year — and spot mismatched or restamped numbers.
• Originality & PaintCheck factory paint configuration for the year to judge an honest restoration.
• Parts AvailabilityGauge restoration cost by how well a model is supported by reproduction and salvage sources.

Identification guides

• ZA vs ZB: telling the Z generations apart
• 5 Star vs M-5: two different tractors, commonly confused
• RTU vs RTS: row-crop vs standard-tread R
• The Twin City tractors: MM’s predecessors

What to inspect

• Identity: confirm the serial/plate matches the claimed model and year.
• Engine & fuel system: verify the correct configuration (gas/LP/distillate/diesel) before assuming parts fit.
• Completeness: sheet metal, grille, gauges, and correct wheels are the costly items to source.
• Documentation: ask for the serial and cross-check against our records.

Buyer guides

• How to Inspect Before You BuyA walk-around checklist — confirm identity, judge the mechanicals, and spot the costly-to-source items.
• How to Research ValueWhat an MM is actually worth — using documented sales, condition, completeness, and rarity.

Model-by-model buyer guides and a documented collector-value reference are in progress. We publish value guidance only from documented sale results — not anecdotal asking prices.

General guidance; always inspect in person and verify against factory literature.
