D1

• The sloped hood provides better visibility to the work in front of the blade as well as the overall job site. Better visibility can equal less operator fatigue and more confidence in your work.

Cat small dozers include a suite of Operator Assist features that work seemlessly to save time, effort, fuel, machine wear and overall costs. Cat Grade with Assist is an optional technology available for small dozers.

    
• Steer Assist automates track steering with light or heavy loads and automates blade tilt steering to help push heavy loads with less effort. This feature helps reduce operator inputs by up to 75% and enhances operator efficiency and productivity. Steer Assist is standard with Assist with Attachment Ready Option (ARO). Steer Assist 3D is standard with Grade 3D with Assist.

    

• Stable Blade Lift and Tilt automatically works behind the scenes to allow operators to create smooth surfaces with less effort using accelerometers on the blade and chassis with an advanced algorithm to make minor blade raise and lower movements. Stable Blade Lift and Tilt is standard with Assist with ARO and Grade 3D with Assist.

    

• Blade Load Monitor provides real-time feedback of current load vs. target load to fully utilize machine capacity benefiting operators of all skills levels. Automatically compensates for ground conditions. This feature is not available indoors or in areas where a GPS signal is not available. Blade Load Monitor is standard with Assist with ARO and Grade 3D with Assist.

    

• Low Slip Traction Control prevents excessive track slip to improve machine efficiency and reduce burden on the operator. Feature offers two modes: Normal Mode helps when pushing heavy blade loads by limiting non-productive track slip, recommended for most applications. And Low Slip Mode limits track slip for applications sensitive to slip such as spreading material on top of a liner, select this mode when needed. Traction Control is standard with Assist with ARO and Grade 3D with Assist.

    

• AutoCarry™ raises and lowers the blade to maximize pushing capability and prevent excessive track slip when pushing heavy loads. Feature is designed to work in unison with other Operator Assist Features. Not available indoors or in areas where a GPS signal is not available. AutoCarry is standard with Assist with ARO and Grade 3D with Assist.

    

• Scalable 2D and 3D Cat Grade is an optional feature that makes your job up to 39% faster with up to 82% fewer operator inputs and less rework by maintaining blade angles for better surface quality – even with less experienced operators.

    

• Cat Command remote control is an optional feature that takes you off the machine and away from hazardous conditions, dust, noise or vibration or operating on unstable surfaces. Eliminates risk of injury from climbing on or off the machine. Integrated with dozer systems, Cat Command enables smooth, precise control with access to all machine functions and advanced features (if equipped) for maximum efficiency and productivity. Availability varies by region.

• The D1 features the lowest fuel consumption in this size class with the same great performance you’ve come to expect. Up to 20% improvement and no performance sacrifice when ECO mode is active.

• The spacious and comfortable cab features an optional heated and ventilated seat, along with heated joystick controls to make the operator comfortable no matter what the conditions are outside. The seat height and armrests can be easily adjusted to the operator’s preference.

• This new and improved optional 10 in (254 mm) touchscreen, color display is easy to use, with a great view of machine settings, rearview camera and Slope Indicate/Slope Assist screens. The large reversing camera gives the operator better visibility to the job site.

• The D1 is available with either a Sealed and Lubricated Track (SALT) or Abrasion undercarriage to best suit your application. The undercarriage has a longer life resulting in less down time. A one piece mainframe/track roller frame design and the large, double reduction planetary final drive allow the machine to push heavy loads.

    
• The Cat® C3.6 engine meets U.S. EPA Tier 4 Final, EU Stage V, Japan 2014, and Korea Tier 5 emission 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.

    

• Auto Engine Speed Control helps reduce unnecessary fuel burn and greenhouse gas emissions by allowing the engine to automatically go into idle mode when the machine is not working.

    

• 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.

    

• Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.

    

• 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.

*Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel.
