John Deere has a proud history in serving the earth moving industry. Since the model MC Dozer manufactured in 1947, John Deere construction has been at the leading edge of the industry. Colorado Machinery has been representing Deere Construction since 1967; adding additional product lines to better serve you, our customer.
At Colorado Machinery, we have what you need to get the job done.
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.
Our EPA IT4/EU Stage IIIB technology is simple, fuel efficient, fully integrated, and fully supported.It employs field-proven cooled exhaust gas recirculation (EGR) for reducing NOX, and a diesel particulate filter and diesel oxidation catalyst to reduce particulate matter.Available reversing hydraulic-powered fan automatically back-blows the cooler cores at preset intervals. When conditions demand more frequent cleaning, simply press a button to actuate the reversing cycle.Individually replaceable wet-sleeve engine-cylinder liners provide uniform engine cooling and long term durability.
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.
Separate, completely sealed hydraulic and hydrostatic systems with common fluid and filter codes eliminate the possibility of cross-contamination, leaving you with fewer maintenance issues to worry about.Accessible, clean-hose routing and Cordura® sleeve protection for cylinder lines to guard against accidental damage on the jobsite.With optional Integrated Grade Control (ICG), wiring harnesses, sensor mounts, control valves, and monitor bracket are factory installed. So adding your preferred grade- control system is easy. Simply plug in the components, calibrate, and go to work.
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.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®.
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.
Hinged side shields swing open wide for convenient access to dipsticks; fill tubes; batteries; master electrical shutoff; and engine, transmission, and hydraulic filters.Front grille tilts forward, simplying cooler-core cleanout. Engine side shields also swing open to provide back-side cooler access.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 in the field and at the shop.
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.High-profile blade with integral spill sheet is now standard equipment.
With John Deere WorkSight™, JDLink™ monitoring provides real-time machine utilization and health data, plus location information. Fleet Care proactively suggests maintenance to correct problems early before they turn into costly downtime. And Service ADVISOR™ Remote enables your dealer to read diagnostic codes, record performance data, and even update software without a trip to the jobsite. It’s the most comprehensive, easy-to-use suite of technology available for increasing uptime and productivity while lowering operating costs. And it’s only available from John Deere.
Onboard diagnostics allow quick and easy troubleshooting without special tools or secondary computers, and without the extra cost of having a technician spend hours manually attempting to isolate issues.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.
John Deere was the first North American dozer manufacturer to utilize dual-path hydrostatic drives in 1976. These dozers feature 30 years’ experience of unmatched best-in-class dual-path hydrostatics with counter-rotation, infinite speed control, live power turns, counter-rotation, and dynamic braking.Infinitely variable range to 8 km/h (5 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.Counterrotation 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.
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 the 550K and 650K even better balance and grading ability than their predecessors. Available extended-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, choose the SC-2™ extended-life option.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.Heavy-duty sealed and lubricated undercarriage is built with no compromise to keep this machine in the field.
