Overview
The Cat® D9 Dozer is a versatile machine designed to be used in a variety of applications, such as ripping overburden, production dozing, stockpiling, winching, site maintenance, fleet support and reclamation. It can be equipped with a number of blade options to meet site-specific needs. A highly reliable and fully integrated Cat machine, the D9’s components work together to ensure top performance, high availability and long life. Features like the new stator clutch torque converter boost efficiency and reduce fuel usage, and a number of onboard technology solutions further increase efficiency and performance. These improvements — and more — make the D9 a dozer that delivers a lower overall cost per unit of material moved.
