Product of the Week - Komatsu D39EX/PX-24 crawler dozer

Komatsu's new D39EX/PX-24 crawler dozer features a 3.26-liter, 105-horsepower, EPA Tier 4 Final certified SAA4D95E-7 engine that offers the same power, while increasing fuel efficiency with the addition of the selective catalytic reduction system and diesel exhaust fluid (DEF). A new water-cooled, variable flow turbocharger is designed for durability and 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 are designed to help reduce idle time and save fuel.         

New standard, operator-selectable, automatic reverse grading mode enables automatic blade control, per customer feedback. A new triple labyrinth final drive and cover design are designed to provide improved protection from mud and debris.

Other noteworthy features include a choice between quick-shift, three-speed mode and a variable, 20-speed customizable transmission mode to suit personal preferences. The dozer's proprietary engine and hydrostatic transmission technology is designed to improve machine efficiency and cut fuel consumption.

A Level 5 KOMTRAX telematics system and monitor provides key machine metrics, including DEF consumption, fuel level, operating hours, location, cautions and maintenance alerts. The new operator ID also makes it possible to view KOMTRAX data by job, application or operator. A large multi-lingual, 7-inch, high-resolution LCD monitor with Ecology Guidance helps operators monitor machine performance in an effort to maximize fuel efficiency and provide real-time integrated diagnostics for troubleshooting without a laptop. A standard rear-view monitoring system promotes increased operator awareness of potential worksite hazards.
