GRADE with 3D and Slope Assist™ help achieve the best quality grading results, while new technologies make machine operation easier and more efficient.

Up to 10% Lower Total Ownership Cost

with improved fuel economy, long undercarriage life and easy maintenance.

Up to 15% More Performance

with customizable operator settings, improvements in grade control features and optimum machine balance for smooth, fast finish grading.

Features At A Glance

Displaying 1-6 of 6

IMPROVED VISIBILITY

IMPROVED VISIBILITY

  • New 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.
GRADE TECHNOLOGY

GRADE TECHNOLOGY

        
  •     

    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 Grade 2D and 3D with Assist 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.
UP TO 10% IMPROVED FUEL ECONOMY

UP TO 10% IMPROVED FUEL ECONOMY

  • The D3 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.
COMFORTABLE WORK SPACE

COMFORTABLE WORK SPACE

  • 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.
BIGGER, BETTER DISPLAY WITH CAMERA

BIGGER, BETTER DISPLAY WITH CAMERA

  • 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.
DURABLE UNDERCARRIAGE

DURABLE UNDERCARRIAGE

        
  • The D3 is available with either a Heavy Duty (HD) 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.
