Komatsu America Corp. D155AX-7 crawler dozer is powered by an EPA Tier 4 Interim and EU Stage 3B emission certified Komatsu engine. The powerful SAA6D140E engine is rated at 354 net horsepower. The efficient automatic transmission is matched with the new engine to achieve exceptional productivity and maintains the same excellent fuel economy as the model it replaces. Komatsu’s new crawler dozer has an operating weight of 87,100 pounds. In addition, the D155AX-7 builds on the SIGMADOZER* blade that was introduced in 2006, but now incorporates a new auto blade pitch function. The new dozer is equipped with the latest KOMTRAXÒ where hour meter, location, cautions and maintenance alerts – to name a few of its features – are relayed to the web application for analysis. The KOMTRAX fleet monitoring system increases machine availability, reduces the risk of machine theft, allows for remote diagnosis by the distributor, and provides a wealth of other information.
