The Case dealer: Your professional partner

Start with world-class Casemachinery and attachmentsYour Case dealer will help youwork smarter and faster by select-ing equipment that delivers quality,performance and operator comfort.Your dealer has the knowledge andexperience necessary to guide youin choosing the right attachmentsso you can…• Work faster with less wear on your

equipment• Reduce the number of machines

you need• Increase your capabilities

Let your Case dealer service yourmachine on the jobsiteYou’ll be back in the dirt fasterwhen your Case dealer servicesyour equipment on the jobsite.Advantages include…• Saving time and the cost of

transporting machines to and fromyour dealer

• Reducing costs due to downtime• Reducing service staff and stocking

fewer parts

Manage your equipment betterThe Case Care PlusPac™ is a pre-paid maintenance plan designedespecially for your machine.

Factory-trained Case techniciansperform routine inspections andregular service to detect problemsbefore they start. Other plans,such as the Machine ProtectionPlusPac, can be purchased toextend protection beyond the basewarranty. Add the GlobalTRACS®

Fleet Management CommunicationsSystem to complete your program.GlobalTRACS gives you the infor-mation to manage your fleet betterwhile protecting it against theft.Ask your local Case dealer aboutadding value and peace of mindto your machine with thesehelpful programs.

Power behind the pushFor the really big jobs, you need acrawler dozer with the fortitude to pushdirt, mud, or whatever Mother Naturedeals on a given day. While the power-train provides the driving force behindany crawler dozer, you need a heavy-duty engine to power it. The 1650K and1850K get their power from high torque,long lasting, 6-cylinder diesel enginesthat maximize productivity. These ruggedengines are extremely durable andfeature outstanding fuel economy.

With a 5.9-liter engine in the 1650K andan 6.7-liter engine powering the 1850K,these dozers keep pushing on, hour afterproductive hour.

Premium push powerSmart engineering makes the most ofpower and speed—the torque converterautomatically matches speed to loadconditions for optimal push power whilepreventing driveline shock, protectingyour investment. Torque multiplicationdelivers maximum drawbar pull—onthe 1850K, that’s 65,200 lbs. (290.0 kN)in first gear.

Three-speed PowershiftTransmission smoothes the rideThe Case three-speed PowershiftTransmission provides outstandingdurability and performance, withelectronically controlled, smoothlymodulated shifts. The PowershiftTransmission features two specialmodes, Auto Shift and Auto Load.

In the Auto Shift Mode, the unit shiftsfrom 1st forward to 2nd reverse, andback to 1st forward for faster, easier, andmore efficient operation. This is reallyhandy when you’re doing precisiongrading work.

In the Auto Load Mode, thetransmission downshiftsautomatically whenengine RPM drops belowthe preset speed, allow-ing you to concentrateon the job. Auto Loadis designed for highspeed bearing loadssuch as light grading.

Doze where you want to…PowerSteer moves you in the rightdirection, wherever it isThe exclusive Case hydraulic variablePower Steer feature delivers maximumpower to both tracks. This feature letsyou push a full load of material througha turn with no problem. A single, easy-to-use lever controls both directionand steering. The drivetrain deliversoutstanding power to each track throughbeefy double-reduction final drives.

There’s absolutely no need to brake orlift the blade to lighten the load whenturning—no wonder we call it “PowerSteer.” This means you’ll make fewerpasses to move material for greaterproductivity. You’ll find these dozersare much more productive thancompetitive machines using clutchand brake steer systems. And thePower Steer feature makes the dozereasy to run, improving productivity,reducing operator fatigue, and loweringoperating cost per cubic yard.

Maximum maneuverabilityCounter-rotation gives you maximummaneuverability. One track movesforward, one track reverses, and thedozer rotates in place. The 1650K and

1850K can turn withintheir own length.It doesn't get anybetter than that.

Long Track, Wide Track, and Low Ground Pressure VersionsThe 1650K and 1850K are available in a wide variety of undercarriage andblade versions to match application requirements. Correctly matching themachine configuration to the application results in maximum productivityand efficiency, improving your bottom line.

The Long Track (LT) is perfect for rough grading and stumping. Select theExtra Long Track (XLT) version for precision grading and increased flotation.The Wide Track (WT) version provides extra stability and accommodateswider blades for finish grading or slope work. For applications requiringlower ground pressure, the LGP Track version maximizes flotation whileproviding superb blade coverage. Ask your Case dealer to help youdetermine the best track/blade combination for your application.

Blade visibilityVisibility to the blade is important for precision work –even with machines as productive as these. The narrowdash and tapered engine compartment on these dozerspermit the operator to see the cutting edge of the bladeand monitor material flow off the blade.

Equalizer Beam SuspensionThe Case 1650K and 1850K Dozers feature anoscillating undercarriage, which means the tracksfollow the terrain, no matter what the conditions, foroutstanding traction, stability and blade control. Theoscillating undercarriage makes these dozers highlyproductive in all kinds of applications, generatinggreater revenue for your business.

POWER AND VERSATILITY

Iso-Mounted Cab/ROPSThe operator platform is isolation mounted from themain frame to cushion your body from the effects ofnoise and vibration, providing a comfortable ride,reducing fatigue, and increasing your productivity levels.

Power Angle Tilt OptionThe Power Angle Tilt (PAT) blade is standard onthe 1650K and is available as an option on the1850K. The PAT blade provides the flexibility thattoday’s job sites require. It is ideally suited tobackfilling, finish and rough grading, mediumdozing, windrowing, V-ditching, and side-slopeoperation. Simply put, the PAT blade makes aCase 1650K or 1850K Dozer more versatile.

Tapered Track CoversSmooth tapered track covers are just one of thestandard features included on the Case 1650K and1850K Dozers to help ensure long life and minimizeowning and operating costs. Track covers contributeto longer undercarriage life by minimizing packingand resultant undercarriage component abrasion.

In this cab, you’ll hardly know you’re outdoors

Please see your Case dealer for specialapplication needs.

To add versatility to your Case Crawler Dozer, equip itwith attachments and special packages designed foryour application. These include:

The luxurious cab available on the 1650Kand 1850K gives an exceptional view tothe blade and provides a comfortableworking space you’ll tailor to fit yourneeds. The heating, ventilation, andcooling system keeps the environmentjust right—no matter what the weatherconditions. All cabs are equipped with amechanical suspension seat, adjustablearmrests, feature low dB(A), and areradio-ready. Add in the optional, air-suspension, 15-degree swivel seat,and you’ll feel like you’re not evenworking outdoors.

Intuitive controlsErgonomically designed controls helpkeep you relaxed yet focused on thejob. The intuitive, single-lever steering/directional control and the hydrauliccontrol make operation of these dozersa breeze. If you’re a novice operator,you’ll be up to speed quickly. If you’rehighly experienced, you’ll be moreproductive than ever.

VisibilityExpansive, tinted glass provides 360-degree visual command of the entire jobsite. All-around visibility is outstanding.The tinted glass helps reduce eye strainfrom long days in the sun, reducingfatigue and increasing productivity.
