NEXT GENERATION PERFORMANCE

  • Harness 6% more weight and 12% more horsepower than D7E to take on a wide range of dozing and grading tasks.
  • Move up to 8% more material per hour.
  • Like D6 and D8, fully automatic 4-speed powershift transmission continuously adjusts for maximum efficiency and power to the ground without added operator input.
  • SU and S blades are 10% larger to help you get jobs done in fewer passes.
  • Optional FirstCut™ cutting edges for SU blades increase blade payload by up to 35% compared to standard cutting edges.
  • Elevated sprocket gives you better ride and balance, plus more penetration force.
  • Outfit your dozer from the factory to take on the challenges of waste handling, land clearing, stockpile work, dredging and more.

All comparisons to D7E.

TOP TECHNOLOGY CHOICES

  • Cat Grade with Slope Assist™ automatically maintains pre-established blade position without a GPS signal – no additional hardware or software needed.
  • Factory integrated Cat Grade with 3D uses GPS to control the blade so you can get to design plan faster.
  • Cat Grade with 3D has no masts - small antennas are integrated into the cab roof and GPS receivers are mounted inside the cab for better protection.
  • Grade operator interface is intuitive and easier to use: 10-inch (254 mm) touchscreen, Android OS platform, operates like a smart phone.
  • Slope Indicate shows machine cross-slope and fore/aft orientation right on the main display to help operators with slope work.
  • Attachment Ready Option (ARO) comes from the factory with key sensors and wiring installed so you can easily upgrade to fully integrated grade control or blade mounted system.
  • All Cat Grade systems are compatible with radios and base stations from Trimble, Topcon, and Leica.
  • Already invested in a grade infrastructure? You can install grade systems from Trimble, Topcon, and Leica onto the machine.

BOOST OPERATOR EFFICIENCY

  • New assist features just work together behind the scenes to help make machine operation easier.
  • Make the most of every pass with Blade Load Monitor to help you optimize blade capacity.*
  • Stable Blade works seamlessly with operator inputs to help produce a smoother surface.
  • Traction Control automatically reduces track slip to save you time, fuel and track wear.*
  • AutoCarry automates blade lift to help you maintain consistent blade load and help reduce track slip.*

*Feature not operational indoors or in areas where a GPS signal is not available.

COMFORT AND VISIBILITY

  • Common cab with D5 and D6, for a whole new standard in comfort and productivity.
  • Easy-to-use 10-inch (254 mm) touchscreen main display.
  • Standard High Definition rearview camera shows prominently in the main display.
  • Key Features Help, built into the display, gives you an overview of machine and technology features and helpful operating tips.
  • Wide air suspension seat has multiple adjustments for personalized comfort.
  • Ample storage spaces throughout the cab.

BUILT-IN DURABILITY

  • Elevated sprocket protects major components from shock loads.
  • Heavier frame and structures for added durability.
  • Cat C9.3B engine eliminates Exhaust Gas Recirculation (EGR) system for greater reliability; Simplified with a single engine Electronic Control Module (ECM).
  • Redesigned fuel system provides greater reliability and more accurate fuel delivery.
  • Heavy Duty Extended Life undercarriage – HDXL with DuraLink™ – provides up to 20 percent more seal life in high impact conditions.

Comparisons to D7E.

BECAUSE UPTIME COUNTS

  • Elevated sprocket makes cleanout easier and provides convenient, modular service.
  • Standard dozer offers 12-foot (3.7 m) shipping width for easier transport with blade installed.
  • Reversible hydraulic demand fan helps remove debris while you work, saving cleanout and maintenance time.
  • Easy access under the cab floor if needed. Cab can be removed in about 30 minutes.
  • Platform with guard rail makes refueling and DEF fill convenient.

WASTE HANDLING PERFORMANCE

  • Cat Waste Handlers are designed and built from the frame up to take on the challenges of landfill work.
  • Specialized guarding, striker bars and seals help protect machine and undercarriage from impact, wrapping and airborne debris.
  • Waste cab has impact-resistant polycarbonate doors, eliminating the need for door screens.
  • High-debris cooling system with automatic reversing fan and swing-out cleanout access.
  • Lights mounted up and away from main debris area for protection, while still giving you plenty of light on the work area.
  • Waste undercarriage, center-hole track shoes and landfill blades help optimize performance.
  • Laminated thermal shields and insulated Clean Emissions Module.

CONNECT TO GREATER EFFICIENCY

  • Product Link™ collects machine data that can be viewed online through web and mobile applications.
  • Access information anytime, anywhere with VisionLink® – and use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve safety and security on your job site.
  • The Cat App helps you manage your assets – at any time – right from your smartphone. See fleet location and hours, get critical required maintenance alerts, and even request service from your local Cat dealer.
  • Remote Troubleshoot saves time and money by allowing your Cat dealer to perform diagnostic testing remotely.
  • Remote Flash updates on-board software without a technician being present, at a time that is convenient for you, potentially reducing update time by as much as 50%.

REMOTE CONTROL READY

  • Cab is Remote Control Ready from the factory with external connector for dealer installation of a plug-and-play roof-mounted remote control unit.
  • Cat Command for Dozing offers remote control operation for enhanced safety and greater productivity.
  • Command uses line-of-sight (LOS) control with an over-the-shoulder console, or a non-line-of-sight (NLOS) option using the Cat Command Station to run the machine remotely.

SUSTAINABILITY

  • Optimize machine performance for greatest productivity, while helping improve fuel efficiency and reduce greenhouse gas emissions with a fully automatic 4-speed transmission with lock-up clutch.
  • The Cat® C9.3B engine meets U.S. EPA Tier 4 Final, EU Stage V, Japan 2014, Korea Tier 5 and China Nonraod Stage IV emissions standards.
  • Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels up to: 20% biodiesel FAME (fatty acid methyl ester) ** or 100% renewable diesel, HVO (hydrogenated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.
  • Cat® Grade with Slope Assist™ helps you avoid costly rework and wasteful fuel burn and greenhouse gas emissions by automating your blade position without a GPS signal.
  • Cat® Grade with 3D automates blade movements using a GPS signal helping you follow a grade design, reducing fuel burn and greenhouse gas emissions by improving efficiency and accuracy.
  • AutoCarry™ automates blade lift to reduce track slip for maximum efficiency on each pass to help lower fuel burn and greenhouse gas emissions.
  • VisionLink® displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
  • Remote Flash minimizes downtime and maintenance time while keeping your asset running with maximum efficiency. Alerts for machine updates are sent virtually from your Cat dealer and updates can be deployed without a dealer technician needing to be onsite.
  • Remote Troubleshoot decreases maintenance time and keeps your machine running with maximum efficiency by allowing your Cat dealer to virtually test the machine while working. Once a problem is identified, a technician can fix it the first time, saving time and money.

All comparisons to D7E. Productivity, fuel and CO2 emissions vary by application. CO2 emissions calculations based on a reference work cycle using 2.2 U.S. gallons per hour of #2 U.S. diesel fuel. Applies IPCC2006 methodology using U.S. EPA Emissions Hub emission factors. Includes DEF (diesel exhaust fluid) related CO2. Fuel measurements are at 15°C. Estimated average fuel consumption improvements are based on tests or Product Link™ data where available. Productivity improvements are based on test data.
**Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel.
