K Komatsu’s new D39-24 dozers are powerful, efficient and available either as a conventional dozer or with Komatsu’s integrated machine control system. A new standard feature on all versions is an automatic reverse grading mode that allows the operator to enable automatic blade control while reversing, a feature that many customers requested. The D39s are powered by a 105-hp Tier 4 Final engine that increases fuel efficiency by up to 5 percent over previous models without affecting power. The new water-cooled Variable Flow Turbocharger increases durability and engine response. Other enhancements on the D39EX/PX-24 and D39PXi-24 include a new Triple Labyrinth final drive and cover design that provides more protection from mud and debris. The D39i features Komatsu’s intelligent Machine Control (IMC) system that provides automatic dozing from the first pass to the finish pass. The system maintains high dozing productivity by maximizing blade load and minimizing track slip. In start-to-finish grading tests, iMC is 8 percent more productive in moving material compared to aftermarket machine control systems, with no need to install and remove blade-mounted sensors daily. “With factory integration and a host of intelligent capabilities, the more owners of the D39PXi-24 run their machines, the more they save,” said Jason Anetsberger, Komatsu senior product manager. “The monthly production gains from starting sooner, finishing faster, using less fuel and saving on materials add up quickly.” All the D39-24 models are smooth, powerful machines designed for a wide range of applications. “Residential and commercial development, highways, golf courses—the D39EX/PX-24 gets it done on any light-to- medium dozing and fine grading application … and more,” said Jonathan Tolomeo, Komatsu product manager. The machine is also easy to transport, he added. Whether purchased, rented, or leased, these machines are covered by Komatsu CARE scheduled maintenance for the first three years or 2,000 hours.
