John Deere 510D vs Komatsu WB156-5

Verdict: John Deere 510D vs Komatsu WB156-5

The John Deere 510D and the Komatsu WB156-5 are both backhoe loaders — here is how they stack up on the figures that matter. John Deere 510D leads on rated power with 100 hp against 99 hp. Komatsu WB156-5 is the lighter machine (7,498 kg vs 16,000 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 1991). In short: choose the John Deere 510D for outright pulling power, or the Komatsu WB156-5 if a tighter budget and lighter footprint matter more.
