Kubota M8540HDN vs Kubota SMZ85

Verdict: Kubota M8540HDN vs Kubota SMZ85

The Kubota M8540HDN and the Kubota SMZ85 are both tractors — here is how they stack up on the figures that matter. Kubota M8540HDN leads on rated power with 86 hp against 84 hp. Kubota SMZ85 is the lighter machine (2,919 kg vs 4,343 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
