John Deere’s new 450K crawler dozer comes with a 4.5L Final Tier 4 diesel engine with 80 hp. The crawler addition delivers 16% more horsepower along with a more impressive power-to-weight ratio, available torque, and drawbar pull than its J-Series counterpart. It features Eco Mode that regulates engine RPM and the hydrostatic transmission to burn up to 20% less fuel in a wide range of applications. The addition of Total Machine Control (TMC) enables operators to customize control of decelerator mode and response, forward/reverse ground speed, steering modulation, forward/reverse speed ratios, and even record machine usage.

All K-Series models boast exclusive turbo cool-down that increases durability by allowing the engine to idle momentarily prior to shutting down. An auto shutdown feature turns the engine off after an operator-determined period of machine inactivity, saving fuel and warranty hours.

The dozer is available with optional electrohydraulic (EH) controls that improve blade response, including increased hydraulic motor capacity that enables 50%  greater blade-raise performance. Additionally, EH controls means the dozer is grade-control ready, and the John Deere “open architecture” design makes adding a grade-control system simple.
