Kubota B21 vs Kubota BX24

Verdict: Kubota B21 vs Kubota BX24

The Kubota B21 and the Kubota BX24 are both backhoe loaders — here is how they stack up on the figures that matter. Kubota BX24 leads on rated power with 23 hp against 21 hp. Kubota BX24 is the lighter machine (1,542 kg vs 1,808 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Kubota BX24 is the newer design (2006 vs 2001). In short: choose the Kubota BX24 for outright pulling power, or the Kubota B21 if a tighter budget and lighter footprint matter more.
