Published on: Apr 20, 2017

The newly launched D51 EX/PX-24 crawler dozer from Komatsu  has  Tier 4 Final engine and an electronically-controlled hydrostatic transmission.  These two features provide up to 13 percent less fuel consumption along with  better maneuverability. Also the new model has high-capacity blade with wear-resistant moldboard, which can increase production by 15 percent in comparison to the previous model versions. 

Jonathan Tolomeo, product manager, Komatsu America said, "The D51EX/PX-24 is a versatile machine, at home on jobsites from landscaping to site prep, as well as highway projects where you're sculpting on and off ramps, for example,"

Among other features the new Komatsu Diesel Oxidation Catalyst and Selective Catalytic Reduction ( system reduce particulate matter and NOx, using 100% passive regeneration without a diesel particulate filter. The new programmable auto-idle shutdown helps reduce unproductive idle time and saves fuel thereby enhancing fuel efficiency.

There are two operator selectable transmission modes - quick-shift, three-speed mode, and a variable, 20-speed mode  providing options to suit operator preference and application. The new model also has rear mounted, high capacity radiator with tilt-up, reversible fan module which are  easy to maintain and gain access to cooler cores.
