Weighing 109,900 pounds, Komatsu’s D275AX-5 crawler dozer features a Tier 3 engine — the turbocharged SAA6D140E-5 diesel engine, which provides 449 net horsepower. A new power train electronic control system improves operation and productivity. Blade capacities are 17.9 cubic yards (Semi-U dozer) and 21.7 cubic yards (U dozer). Fuel consumption is reduced significantly, says the company, by use of the lock-up torque converter function. The new, ergonomically designed Palm Command Control System offers operators a relaxed posture and excellent fine control to reduce operator fatigue.
