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.
GRADE with 3D and Slope Assist™ help achieve the best quality grading results, while new technologies make machine operation easier and more efficient.
with improved fuel economy, long undercarriage life and easy maintenance.
with customizable operator settings, improvements in grade control features and optimum machine balance for smooth, fast finish grading.

| Air Conditioning | The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a or R1234yf (Europe). See label or instruction manual for gas refrigerant identification. If machine is equipped with R134a (Global Warming Potential = 1430), the system contains 1.8 kg (4.0 lbs) of refrigerant, which has a CO2 equivalent of 2.574 metric tonnes (2.873 tons). If machine is equipped with R1234yf (Global Warming Potential = 0.501), the system contains 1.7 kg (3.75 lbs) of refrigerant, which has a CO2 equivalent of less than 0.001 metric tonnes (0.001 tons). |
