D8

Medium Dozers

The Cat® D8 dozer (formerly D8T) increases your dozing productivity up to 18% without using more fuel. This means you can move more material in less time, at a lower cost per ton, so you get a faster payback on your equipment investment. The D8 bulldozer offers unprecedented ease of operation as well. A Caterpillar designed, smooth shifting, fully automatic 4-speed transmission makes it easy for operators of all experience levels to achieve optimal productivity and efficiency without having to manage gear shifts. Factory integrated Grade technology options help you get quality work done even faster, from first pass to finish grade, while relying less on operator input.
