The Cat® D3 delivers superior performance and the broadest choice of technology features to help you get the most from your dozer. Nimble and responsive, it has power for dozing and finesse for grading. Fully hydrostatic transmission gives you seamless acceleration, so you can get the job done quickly. The load sensing system automatically optimizes ground speed based on load, for the greatest productivity and fuel efficiency.

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, Grade, and Cat Command Features that work seamlessly to save time, effort, fuel, machine wear and overall cost.
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.
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.
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.
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.
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.
