Caterpillar 430D vs Komatsu WB156-5

Verdict: Caterpillar 430D vs Komatsu WB156-5

The Caterpillar 430D and the Komatsu WB156-5 are both backhoe loaders — here is how they stack up on the figures that matter. Komatsu WB156-5 leads on rated power with 99 hp against 98 hp. Caterpillar 430D is the lighter machine (7,356 kg vs 7,498 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Komatsu WB156-5 is the newer design (2006 vs 2000). In short: choose the Komatsu WB156-5 for outright pulling power, or the Caterpillar 430D if a tighter budget and lighter footprint matter more.
