Kubota B1121 vs Kubota XB-1

Verdict: Kubota B1121 vs Kubota XB-1

The Kubota B1121 and the Kubota XB-1 are both tractors — here is how they stack up on the figures that matter. Kubota XB-1 leads on rated power with 12 hp against 11 hp. Kubota XB-1 is the lighter machine (489 kg vs 600 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
