Komatsu America Corp has introduced the new D39EX/PX-24 crawler dozer, a smooth, powerful, quiet machine for grading across a wide range of applications.

“I'd say to anyone looking for a nimble, powerful machine that's easy to transport and a breeze to operate, this is the dozer for you,” 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,” Tolomeo said.

Under The Hood

 A 3.26 L, 105 HP, EPA Tier 4 Final certified, 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).

 A new water cooled, Variable Flow Turbocharger, provides added durability and excellent engine response.

 The Komatsu Diesel Oxidation Catalyst provides 98% passive regeneration and does not interfere with machine operation.

 New auto-idle shutdown and economy modes that help reduce idle time and save fuel.

Machine Performance Enhancements

 New standard, operator-selectable, automatic reverse grading mode enables automatic blade control, per customer feedback.

 New Triple Labyrinth final drive and cover design provide improved protection from mud and debris.

Other noteworthy features on the D39EX/PX-24 crawler dozer:

 A choice between quick-shift, three-speed mode and a variable, 20-speed customizable transmission mode to suit personal preferences.

 Proprietary engine and hydrostatic transmission technology that improves machine efficiency and cuts fuel consumption.

 Pioneering Level 5 KOMTRAX telematics system and monitor that provides key machine metrics, including DEF consumption, fuel level, operating hours, location, cautions and maintenance alerts.

 New Operator ID also makes it possible to view KOMTRAX data by job, application or operator.

 Large, multi-lingual, 7 inch, high-resolution LCD monitor with Ecology Guidance that 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.

The D39EX/PX-24, whether rented, leased or purchased, is covered by the Komatsu CARE program for the first three years or 2000 hours, whichever comes first. Komatsu CARE includes scheduled factory maintenance, a 50-point inspection at each service and two complimentary factory recommended services of the SCR (Selective Catalytic Reduction)/DEF (Diesel Exhaust Fluid) system, including tank flushes and strainer cleaning at 4,500 and 9,000 hours in the first five years.
