450K Crawler Dozer

EPA Final Tier 4 (FT4)/EU Stage IV diesel meets emission regulations without loss of power or torque. Four-valve head delivers increased intake-air and exhaust-gas flow for each wet-sleeve cylinder, for long-lasting performance.

Standard Eco mode maximises fuel usage by up to 20% compared to conventional torque-converter transmissions, automatically adjusting engine rpm and powertrain settings based on load, without loss of performance. Eco mode automatically adjusts engine rpm and hydrostatic (HST) transmission settings based on load while maintaining ground speed.

When you order your dozer with electrohydraulic (EH) controls, it’s grade-control ready, giving you the ability to add the grade-control system of your choice. Optional Slope Control provides in-depth factory integration and is supported by your John Deere dealer.

Slope Control system provides simple-to-use grade control includes a deluxe LCD colour monitor
that gives a real-time display of mainfall and cross-slope information, allowing operators to set desired slopes, put the system in automatic, and let it do the work. It helps both new and veteran operators hold grade with less effort and without needing an external elevation reference.

Cab-forward design allows a commanding view behind, below, and beyond the blade. Side and rear visibility from inside the cab is open to the surrounding job site.

Sealed-switch module (SSM) allows low-effort control of keyless start and enables exclusive features such as turbocharger cool-down, auto shutdown, and Eco mode.

Total Machine Control enables an operator to customise control of decelerator mode and response, forward/reverse ground speed, steering modulation, and forward/reverse speed ratios, and even record machine usage.

Available quick fluid-evacuation system helps speed servicing. 500-hour engine oil and 2,000-hour transmission and hydraulic fluid intervals decrease maintenance downtime and expense. In-cab diagnostic monitor also provides easy-to-understand messages that help speed troubleshooting.
