Kubota M135GX vs Kubota M6122

Verdict: Kubota M135GX vs Kubota M6122

The Kubota M135GX and the Kubota M6122 are both tractors — here is how they stack up on the figures that matter. Kubota M6122 leads on rated power with 122 hp against 118 hp. Kubota M135GX is the lighter machine (4,705 kg vs 6,000 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 2012). In short: choose the Kubota M6122 for outright pulling power, or the Kubota M135GX if a tighter budget and lighter footprint matter more. Compare the full spec tables below before booking a demo.
