Kubota M115GX-III vs Kubota M6122

Verdict: Kubota M115GX-III vs Kubota M6122

The Kubota M115GX-III and the Kubota M6122 are both tractors — here is how they stack up on the figures that matter. Kubota M115GX-III leads on rated power with 123 hp against 122 hp. Kubota M6122 is the lighter machine (6,000 kg vs 10,604 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Kubota M6122 holds more fuel (230.1 L vs 190.0 L) for longer stints between fills. Kubota M6122 is the newer design (2020 vs 2016). In short: choose the Kubota M115GX-III for outright pulling power, or the Kubota M6122 if a tighter budget and lighter footprint matter more.
