Kubota M8580 vs Kubota M85D

Verdict: Kubota M8580 vs Kubota M85D

The Kubota M8580 and the Kubota M85D are both tractors — here is how they stack up on the figures that matter. Kubota M8580 leads on rated power with 85 hp against 84 hp. Kubota M85D is the lighter machine (3,289 kg vs 3,799 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Kubota M85D holds more fuel (190.0 L vs 104.8 L) for longer stints between fills. Kubota M85D is the newer design (2005 vs 1991). In short: choose the Kubota M8580 for outright pulling power, or the Kubota M85D if a tighter budget and lighter footprint matter more. Compare the full spec tables below before booking a demo.
