550K Crawler Dozers

When customers sound off, we listen. So when our Customer Advocate Group (CAG) participants asked us to turn down the noise and turn up productivity on our 550K Dozer, we responded with a spacious, redesigned cab that's noticeably quieter. An EPA Final Tier 4 (FT4)/EU Stage IV diesel engine for work in nonattainment areas. And Eco mode for improved fuel efficiency with no loss of productivity. There's more to like in the K-Series — such as a hydraulic-driven fan that provides efficient cooling, reduces noise, and conserves precious fuel. And a convenient sealed-switch module for fingertip control of numerous one-of-a-kind features.
