Komatsu increased the Sigmadozer blade capacity on its new D85-18 more than 22% above the -15 models, yet expects 15% improved fuel efficiency with the more-productive machine. The 264-hp Komatsu diesel got selective catalytic reduction (SCR) to reduce NOx emissions using diesel exhaust fluid (DEF). The exhaust aftertreatment achieved U.S. EPA Tier 4 Final emissions certification, and Komatsu says it will reduce fuel consumption up to 5% with no loss of performance.
A new automatic transmission with E- and P-Modes is designed to help match machine performance to the work at hand. E-Mode is for general dozing, leveling and spreading, providing adequate speed and power while reducing fuel usage up to 10%. The P-Mode is for heavier applications where engine power should have priority over fuel conservation.
The standard, 9.4-cu.-yd. Sigmadozer blade pushes through the soil easier, like a spade compared to a scoop shovel. With standard power pitch, Komatsu says it increases dozing productivity by up to 15% over a conventional semi-U blade.
A new Operator Identification System reports key operating information for multiple operators and a new Auto Idle Shutdown function helps reduce idle time.
