We hear you loud and clear.

When our customers sound off, we listen. So when you asked us to turn down the noise and turn up productivity on our 550K Crawler Dozer, we responded with a spacious, redesigned cab that's up to 50% quieter. And a more powerful EPA Interim Tier 4 (IT4)/EU Stage IIIB diesel engine.

Equipment owners and operators will also find lots 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 and functions.

The K-Series are loaded with even more performance enhancements, like Total Machine Control (TMC). Standard on all of our K-Series Crawler Dozers, this performance-enhancing feature provides customized decelerator mode and response, forward/reverse ground-speed ranges, steering modulation, and more. It enables your operators to do their best, by being themselves.
