K Komatsu is building on the growing success of its intel- ligent dozers by introducing the updated Tier 4 Final version of the D61i dozer. The new dozer, the Dash-24, reduces fuel consumption and operating costs while delivering the integrated intelligent Machine Control (iMC) that Equipment World called a “killer feature” in its review of the dozer. From heavy dozing to fine grading, the machine can operate automatically, thanks to the iMC system. The dozer produces up to 8 percent greater efficiency in moving materials in start-to-finish grade testing compared to typical aftermarket machine control systems. “From first to last pass—rough cut to finish grade—the machine senses blade load, minimizes track slip and ensures operators get the most from every push,” said Sebastian Witkowski, Komatsu product manager. Since the system is fully integrated in the dozer, Komatsu has eliminated “the need to install or remove blade-mounted sensors each day. That not only saves on wear and tear and the potential for downtime, it saves operators valuable time that can be used to run the machine longer,” he added. Komatsu’s integrated system completely eliminates the cables needed in aftermarket systems. The new dozer—equipped with a 6.8-liter, 168-hp Komatsu engine—gives operators a choice between a quick-shift, three-speed mode and a variable 20-speed customizable transmission mode. The new auto-idle shutdown and economy modes limit the amount of time the dozer idles, saving fuel and wear on the machine. The D61i also features a standard rearview monitor- ing system that gives the operator a better view of potential worksite hazards. Many users find that iMC dozers are safer because the operator doesn’t have to monitor the blade constantly, allowing him to spend more time watching for possible hazards. Like all Tier 4 Final Komatsu machines, the D61i-24 is covered by Komatsu CARE for the first three years or 2,000 hours, whether it is purchased, leased or rented. Komatsu Care covers scheduled factory maintenance, a 50-point inspection at each service, plus two compli- mentary Komatsu Diesel Particulate Filter exchanges and DEF flushes in the first five years.
