450K/550K/650KCRAWLER DOZERS60–78 kW (80–104 hp)

We hear youloud and clear.When customers sound off, we listen. So when participantsof our Customer Advocate Group (CAG) asked us to turn downthe noise and turn up productivity on our K-Series Dozers,we responded with a 450K that’s 16-percent more powerfulthan the previous model. Eco mode that regulates engine rpmand hydrostatic transmission to burn up to 20-percent less fuelin a wide range of applications. And Total Machine Control onthe durable sealed-switch module for easy customization andreliable control of a variety of machine functions. There’s moreto like in the K-Series.23Specifications450K450K LGPRated Power60 kW (80 net hp)60 kW (80 net hp)Base Weight7959 kg (17,510 lb.)8522 kg (18,752 lb.)Specifications550K550K LGPRated Power69 kW (92 net hp)69 kW (92 net hp)Base Weight8981 kg (19,758 lb.)9544 kg (21,000 lb.)Specifications650K XLT650K LGPRated Power78 kW (104 net hp)78 kW (104 net hp)Base Weight9691 kg (21,320 lb.)10 156 kg (22,343 lb.)

Pushes envelopes, too.Power turns. Counter-rotating tracks. Power management. Infinitelyvariable travel speeds. John Deere has been introducing productivityboosting advantages on our crawler dozers for decades. And our 650K,550K, and 450K are loaded with performance enhancements, includingEco mode and Total Machine Control (TMC).Our EPA Final Tier 4 (FT4)/EU Stage IVdiesels meet emission regulations withoutsacrificing power or torque. The 450Kdelivers 16-percent more horsepoweralong with a more impressive powerto-weight ratio, available torque, anddrawbar pull than its J-Series counterpart.Simply set maximum desired ground speedand the power-management system automatically maintains peak engine rpm andpower efficiency without stalling or shifting.451. TMC enables an operator to customizecontrol of decelerator mode and response,forward/reverse ground speed, steeringmodulation, and forward/reverse speedratios, and even record machine usage.Counter-rotation boosts productivity byenabling an operator to overcome heavycorner loads and quickly reposition theblade on the go. Provides space-savingspot turns, too.Infinitely variable range to 11 km/h(6.8 mph) allows total flexibility to matchground speed to the load. Travel can alsobe varied to fit specific applications, terrainconditions, or operating preferences —and even limited to maximize undercarriage life.2. Eco mode maximizes fuel economyby up to 20 percent compared toconventional torque-convertertransmissions without sacrificingperformance, automatically adjustingengine rpm and transmission settingsbased on load.3. When you order your dozer withelectrohydraulic (EH) controls, it’sgrade-control ready. Our “openarchitecture” design makes addinga grade-control system as easyas plugging in the components,calibrating, and going to work.

With you on the jobsite.K-Series Dozers quietly go about the business of helping make your operatorscomfortably productive. Inside their roomy, well-appointed cabs, you canalmost hear fatigue drop. You’ll discover what your operators need to getmore done in a 450K, 550K, or 650K.Sealed-switch module (SSM) allows low-effort control of keyless start andenables exclusive features such as turbocharger cool-down, auto shutdown,and Eco mode. Touchpad security system requires a numeric pass code (whenactivated) to help prevent unauthorized machine operation.Generous hydraulic flow and precise metering deliver powerful and quickblade response, while providing the natural “feel” that makes the mostof an operator’s grading ability.At just 75 dBA, the cab is noticeably quiet. Spacious and comfortable, too.11. Opt for the 360-deg. lightingpackage to extend your workdaybeyond daylight.672. Cab-forward design allows acommanding view behind, below,and beyond the blade. Side and rearvisibility is virtually unobstructed.3. Optional electrohydraulic (EH) controlssignificantly improve blade response,including increased hydraulic motorcapacity on the 450K that enables50-percent greater blade-raiseperformance. Blade Vibrate featurefor Power-Angle-Tilt (PAT) bladesautomatically shakes off dirt at thetouch of a button.

Built to take it on— and beyond.Tough conditions call for strong solutions. Our K-Series Dozersare built to tackle some of the most difficult applications you canput in front of them. When you know how they’re built, you’ll seewhat they can do for your operation.Eco mode automatically adjusts enginerpm and hydrostatic (HST) transmissionsettings based on load while maintainingground speed, to help optimize fueleconomy as much as 20 percent compared to conventional torque-convertertransmissions.1. Heavy-duty sealed and lubricated undercarriage is built without compromise tokeep these machines in the field. AvailableMaximum Life Undercarriage delivers up totwice the bushing life, for extra durabilityin extremely abrasive conditions. To furtherreduce maintenance and operating costs,contact your John Deere dealer about ourundercarriage wear-assurance programs.2. Direct-drive fan on the 450K and550K provides efficient cooling,contains noise, and conservesprecious fuel. Variable-speed fanon the 650K includes an optionalreversing feature that runs onlyas needed.Transmission temperature is constantlymonitored to protect the HST system.If temps get too hot or too cold, a warninglight illuminates, and transmission andengine speed are automatically deratedto prevent damage.3. Exclusive turbo cool-down increasesdurability by allowing the engine toidle momentarily prior to shuttingdown. Auto shutdown turns the engineoff after an operator-determinedperiod of machine inactivity, savingfuel and warranty hours.

Declare openseason onoperating costs.We’re pretty open-minded when it comes to keeping uptime up anddaily operating costs down. With our K-Series Dozers, you’ll spendless effort and expense getting ready for work — and more timegetting work done.1. Exhaust filter operation and status areindicated with icons and on-screendisplays. Diagnostic monitor alsoprovides easy-to-understand messagesthat help speed troubleshooting.2. Available quick fluid-evacuation systemhelps speed servicing. 500-hour engineoil and 2,000-hour transmission andhydraulic fluid intervals decreasemaintenance downtime and expense.3. Auto-idle decreases engine speedwhen the dozer is not moving, tohelp maintain quiet working conditions and conserve precious fuel.Operators can program auto-idle toactivate in increments from as soonas five seconds up to 15 minutes.11011Serviceability improvements onthe 550K and 650K over previousmodels include composite fueltank, redesigned diagnosticlines with pressure sensors,and John Deere transmissioncontrol unit software.23

The John Deere WorkSight suite of constructiontechnology delivers Productivity Solutions to helpyou get more done, more efficiently. The in-base,five-year JDLink telematics subscription providesmachine location, utilization data, and alerts to helpyou maximize productivity and efficiency. Otherproductivity solutions include grade-managementand payload-weighing options.To maximize uptime and lower costs, JDLinktelematics also enables John Deere ConnectedSupport. John Deere’s centralized MachineHealth Monitoring Center analyzes data fromthousands of connected machines, identifiestrends, and develops actions to prevent downtime called Expert Alerts. Dealers use Expert Alertsto proactively address conditions that wouldotherwise likely lead to downtime. Your dealercan also monitor machine health and leverageremote diagnostics and programming capabilityto further diagnose problems and even updatemachine software without a time-consuming tripto the jobsite.Ash-service intervals for the diesel particulatefilter (DPF) are condition based, meaning themachine will notify the operator before serviceis required. Typically, ash service is not necessaryuntil the first engine overhaul. Machine application, regular maintenance practices, and type oflubricating oil impact ash-service intervals.
