It's got your fingerprints all over it.
Ok, maybe not YOUR fingerprints. But equipment owners and operators like you had a hand in perfecting the reimagined 850K. Armed with real-world experience, participants in our Customer Advocate Group (CAG) offered their expertise. We listened and responded with numerous K-Series enhancements including additional power and weight for increased productivity. An EPA Final Tier (4)/EU Stage IV diesel engine for work in nonattainment areas. Spacious redesigned cab that's noticeably quieter and more comfortable. And best-in-class serviceability features, such as an innovative easy-to-clean "V-cool" package. Add to those, the unsurpassed operating ease and maneuverability operators have come to expect from our crawlers, and the 850K is an obvious choice. To get your hands on one, see your John Deere dealer.
• 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 to burn up to 25-percent less fuel.
• Dual-path hydrostatic 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 groundspeed, 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).
V-cool design isolates coolers from dust and engine heat for increased efficiency and durability. Positioned behind the heavy-duty grille and fan, coolers are also less vulnerable. Reversing 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.
Flush-fit bottom guards and tight-fitting side shields help keep trash out. Hood and side-shield perforations function as a “first filter,” further preventing entry of most debris. Anything that gets past the five-mm holes also passes through the cooler cores.
Vertical filters allow quick, no-spill changes. Engine, hydraulics, and transmission utilize a common oil, further simplifying service. Available severe-duty fuel filter provides an extra degree of filtration. Includes a heated water separator for cold-weather service.
Sealed hydraulic and hydrostatic reservoirs are separate, eliminating any possibility of cross-contamination.
Accessible, clean-hose routing and Cordora® sleeve protection for cylinder lines to guard against accidental damage on the jobsite.
When you order your dozer grade-control ready, 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.
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®.
Your success depends on your ability to one-up your competition – and grade-control technology has become a must-have tool for maximizing productivity and minimizing daily operating costs.
Unlike traditional aftermarket grade-control systems, which are prone to theft and damage, and take time to set up, John Deere SmartGrade™ Dozers are purpose built. Combining the power of Topcon 3D-MC2 technology with the Deere track load-sensing system, these highly productive crawlers feature a fully integrated grade-control system that is as easy to set up as it is to run. And they're backed by our legendary Deere dealer network.
