Komatsu Introduces D39EX/PX-24 Crawler Dozer
Komatsu America's new D39EX/PX-24 crawler dozer is a smooth, powerful, quiet machine for grading across a wide range of applications. The dozer has Komatsu's super-slant-nose design, change-on-the-fly modes to match power to work conditions, and a hydrostatic transmission that helps improve fuel efficiency.
It's a nimble, powerful machine that’s easy to transport and to operate, said Jonathan Tolomeo, Komatsu product manager. “Residential and commercial development, highways, golf courses - the D39EX/PX-24 gets it done on any of these light-to-medium dozing and fine grading applications and more."
The machine features a 3.26L, 105 HP, EPA Tier 4 final, SAA4D95E-7 engine offers the same power, while increasing fuel efficiency with the addition of the Selective Catalytic Reduction (SCR) system and Diesel Exhaust Fluid (DEF). It uses a new water cooled, Variable Flow Turbocharger to provide excellent engine response. The Diesel Oxidation Catalyst provides 98 percent passive regeneration and does not interfere with machine operation.
To save time and fuel, the machine has auto-idle shutdown and economy modes. New standard, operator-selectable, automatic reverse grading mode enables automatic blade control, per customer feedback. And its Triple Labyrinth final drive and cover design provide improved protection from mud and debris.
A choice between quick-shift, three-speed mode and a variable, 20-speed customizable transmission mode will suit personal preferences. Large, multi-lingual, 7 inch, high-resolution LCD monitor with Ecology Guidance helps operators monitor machine performance for maximum fuel efficiency and follow real-time integrated diagnostics for troubleshooting without a laptop. Standard rear-view monitoring system that promotes increased operator awareness of potential worksite hazards.
