D11 Dozer
The new Cat® D11 Dozer delivers higher productivity at lower cost. The latest technology provides operator with full command of the dozer for safe and efficient operation. This means you can comfortably move more material in less time, at a lower cost per ton, for a faster payback on your investment. This intelligent dozer has a sophisticated machine protection strategy, as well as a machine guidance system which further drives higher productivity and lower cost.
