The 18-metric-ton Tier 4-lnterim 180G LC features a 121-horsepower John Deere PowerTech diesel engine utilizing EGR technology, a DPF and a DOC. A hydrauli-cally driven fan runs only as needed, reducing noise, fuel consumption and operating costs, the company says. An automatic or operator-activated reversing option back-blows cooler cores to keep them clean and free of debris. Three productivity modes (high-productivity, power, economy) allow an operator to choose the digging style that fits the task at hand.
