Kubota M125GX-III vs Kubota M128X

Verdict: Kubota M125GX-III vs Kubota M128X

The Kubota M125GX-III and the Kubota M128X are both tractors — here is how they stack up on the figures that matter. Kubota M128X leads on rated power with 134 hp against 133 hp. Kubota M128X is the lighter machine (4,409 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 M125GX-III is the newer design (2016 vs 2008). In short: choose the Kubota M128X for outright pulling power, or the Kubota M125GX-III if a tighter budget and lighter footprint matter more.
