Kubota B21 vs Kubota BX25D
Verdict: Kubota B21 vs Kubota BX25D
The Kubota B21 and the Kubota BX25D are both backhoe loaders — here is how they stack up on the figures that matter. Kubota BX25D leads on rated power with 23 hp against 21 hp. Kubota BX25D is the lighter machine (1,587 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 BX25D is the newer design (2013 vs 2001). In short: choose the Kubota BX25D for outright pulling power, or the Kubota B21 if a tighter budget and lighter footprint matter more.
