Verdict: Kubota M115D vs Kubota M6121

The Kubota M115D and the Kubota M6121 are both tractors — here is how they stack up on the figures that matter. Kubota M6121 leads on rated power with 115 hp against 113 hp. Kubota M115D is the lighter machine (4,186 kg vs 6,900 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
