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 450K 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.

KEY FEATURES
- 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.
ENGINE
- 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. Hydraulically driven fan runs only as needed, reducing fuel consumption and debris flow through the cores.
- 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.
HYDRAULICS
- 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.
CAB COMFORT
- 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.
- 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 detented 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 allows low-effort control of keyless start, and enables exclusive features such as turbocharger cool-down and auto shutdown. Touchpad security system requires a numeric pass code (when enabled) to help prevent unauthorized machine operation.
EASE OF SERVICE
- Hinged engine side shields swing open wide and the front grille tilts forward for convenient access to dipsticks, fill tubes, batteries, master electrical shutoff, the backside of the cooler, and engine, transmission, and hydraulic filters.
- Fluid-sample ports simplify preventative maintenance. Engine, hydraulics, and transmission utilize a common oil, further simplifying service.
- Conveniently located easy-to-read sight gauges for checking fluid levels
- Exhaust filter operation and status are indicated with icons and on-screen displays. The diagnostic monitor also provides easy-to-understand messages that help speed troubleshooting.
- Vertical filters allow quick, no-spill changes. Available severe-duty fuel filter provides an extra degree of filtration. Includes a heated water separator for cold-weather service.
CPU/MONITOR
- The enhanced multifunction LCD color monitor provides pushbutton access to a wealth of machine info. It also enables you to customize machine settings.
- If a spec is pushed beyond a critical range limit, an alarm will sound and a red warning light activated to unmistakably inform the operator to shut down the machine and investigate the cause.
- Total Machine Control (TMC) enables an operator to easily customize operating characteristics and machine response — for familiar operation and predictable control. TMC can also be used to monitor machine readings such as mileage and hours.
TRANSMISSION
- Infinitely variable range to 11 km/h (6.8 mph) allows total flexibility to match ground speed to the load. Travel can also be varied to fit specific applications, terrain conditions, or operating preferences — and even limited to maximize undercarriage life.
- Counter rotation boosts productivity by enabling an operator to overcome heavy corner loads and quickly reposition the blade on the go. Provides space-saving spot turns, too.
- Simply set maximum desired ground speed and the power management system automatically maintains peak engine rpm and power efficiency without stalling or shifting.
- These dozers steer the same and maintain their preset speed whether working on level ground or a 2-to-1 slope. So there’s never a need to cross-steer or ride a brake.
BLADE
- Closed-cell blade design and robot-welded, fabricated, box-section C-frame is strong and durable.
- The heavy-duty ball-and-socket joint, horizontally designed to resist material buildup for long-term grading precision, is built with unmatched strength and durability in mind.
- To do the job right, easily adjust blade-pitch angle with a single wrench to get the most productivity.
UNDERCARRIAGE
- Blade ratio and center of gravity are optimized, providing the balance needed for superior grade work. More track on the ground and an additional bottom roller give these dozers even better balance and grading ability than their predecessors.
- Available Maximum Life Undercarriage delivers up to twice the bushing life, for extra durability in extremely abrasive conditions. If you want to further reduce maintenance and operating costs, contact your John Deere dealer about our under-carriage wear-assurance programs.
- Heavy-duty sealed and lubricated undercarriage is built with no compromise to keep this machine in the field. Cleaning the undercarriage has never been easier. Specially designed, guarded, and sloped track frames resist buildup and ensure quick and easy clean-out when needed.
- Triple-reduction planetary final drives are mounted independent of the track frames, where they’re effectively protected.
