We hear you loud and clear.
When customers sound off, we listen. So when participants of our Customer Advocate Group (CAG) asked us to turn down the noise and turn up productivity on our K-Series Dozers, we responded with a 450K that’s 16-percent more powerful than the previous model. An EPA Final Tier 4 (FT4)/EU Stage IV diesel engine for work in nonattainment areas. Eco mode regulates engine rpm and hydrostatic transmission to burn up to 20-percent less fuel in a wide range of applications. And Total Machine Control on the durable sealed-switch module for easy customization and reliable control of a variety of machine functions. We also include Ultimate Uptime featuring John Deere WorkSight™ in base. You get pre-delivery and follow-up inspections, plus three years of JDLink™ Ultimate telematics, machine-health prognostics, and remote diagnostics and programming. You can work with your John Deere dealer to add other uptime services that meet the needs of your operation, too.
• EPA Final Tier 4 (FT4)/EU Stage IV diesel delivers impressive power, torque, and drawbar pull for work in nonattainment areas and unsurpassed productivity.
• Eco mode regulates engine rpm and hydrostatic (HST) transmission system to burn up to 20-percent less fuel in many applications.
• Dual-path HST transmission ensures smooth moves and allows you to push a full load through turns without losing material.
• Total Machine Control (TMC) allows you to customize decelerator mode and response, forward/reverse ground speed, steering modulation, and forward/reverse speed ratios for superb control.
Our FT4/Stage IV diesels meet emission regulations without sacrificing power or torque. We built on our Interim Tier 4 (IT4)/Stage IIIB solution to deliver the best combination of performance, efficiency, and reliability. This technology is simple, fluid efficient, fully integrated, and fully supported.
It employs field-proven cooled exhaust gas recirculation (EGR), easy-to-maintain high-uptime exhaust filters, and selective catalytic reduction (SCR).
Innovative V-Cool design provides convenient access to both sides of the coolers for easy cleanout. Hydraulic-driven fan on the 450K provides efficient cooling, contains noise, and conserves precious fuel.
Eco mode maximizes fuel economy without sacrificing performance, automatically adjusting engine rpm and transmission settings based on load.
Auto-idle helps save fuel by reducing engine speed when the dozer is not moving.
Accessible, clean-hose routing and sleeve protection for cylinder lines to guard against accidental damage on the jobsite.
Our “open-architecture” design makes adding a grade-control system as easy as plugging in the components, calibrating, and going to work, whether your preference be Trimble, Leica, or a factory-installed Topcon 3D-MC2 system.
Standard high-back air-suspension seat and optional deluxe heated and leather-bolstered lower cushion adjust multiple ways for daylong comfort and support. Arm- and footrests also adjust. Operators will find plenty of space to stow beverages, a cooler, and other carry-ons.
Cab-forward design provides a commanding view behind, below, and beyond the blade. Side and rear visibility is also unobstructed. And at just 75 dBA, the redesigned cab is noticeably quiet. Spacious and comfortable, too
The in-dash compartment is ideal for permanent placement of a grade-control monitor or as a lockable compartment for storing.
Overhead radio and storage console includes a 12-volt electrical outlet for powering a cell phone or an iPod®.
Ease of Control
Single lever provides low-effort control of steering, forward/reverse travel, and ground speed. It’s also detected so it doesn’t require an operator’s constant touch or attention, and employs a thumb-actuated travel-speed switch.
The power-management system allows the operator to concentrate on controlling the blade rather than controlling the transmission. The operator simply chooses the maximum speed at which he or she is comfortable operating, and the power-management system automatically shifts and controls machine speed depending on load and grade.
Ergonomic T-bar hydraulic control precisely meters flow for a natural "feel" and provides advanced optimum blade control that will enhance any operator’s grading skills. Blade response is powerful and quick.
Sealed-switch module (SSM) allows low-effort control of keyless start, and enables exclusive features such as turbocharger cool-down and auto shutdown. Engine RPM is controlled by the engine speed increase and decrease buttons on the SSM. Touchpad security system requires a numeric pass code (when enabled) to help prevent unauthorized machine operation.
