John Deere’s new 850K crawler dozer represents years of working side by side with customers. The dozer’s Interim Tier 4 engine uses EGR technology with exhaust filters and provides 187 to 205 horsepower at 1,800 revolutions per minute, depending on machine configuration. The engine’s diesel particulate filters are cleaned automatically during routine operation, so there’s no need to idle down for maintenance. A dual-path hydrostatic transmission automatically matches machine power and speed to load demand, eliminating the need for inefficient gear systems. Inside the cab, noise levels have been reduced by 45 percent, according to the company. The cab features larger access doors and more interior room for better comfort, as well as ample glass and well-positioned in-cab components for great visibility to the blade. Sloped cross members provide lateral strength and visibility to the rear of the blade. The dozer is available in six configurations.
