Kubota B20 vs Kubota BX23S

Verdict: Kubota B20 vs Kubota BX23S

The Kubota B20 and the Kubota BX23S are both backhoe loaders — here is how they stack up on the figures that matter. Kubota BX23S leads on rated power with 23 hp against 20 hp. Kubota BX23S is the lighter machine (275 kg vs 929 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Kubota BX23S holds more fuel (25.0 L vs 20.1 L) for longer stints between fills. Kubota BX23S is the newer design (2017 vs 1990). In short: choose the Kubota BX23S for outright pulling power, or the Kubota B20 if a tighter budget and lighter footprint matter more. Compare the full spec tables below before booking a demo.
