Overview

PRODUCTIVITY THAT PAYS

The Cat® D8 dozer (formerly D8T) increases your productivity up to 18% without using more fuel. A fully automatic 4-speed transmission and a choice of factory integrated Grade technologies help make optimal productivity and efficiency easier for operators of all experience levels.

Benefits

Zero Additional Fuel

Move more material without burning more fuel in most applications. Use up to 11% less fuel in lighter applications.

Up To 18% More material per hour

Fully automatic transmission, added power and steering performance team up for a new level of productivity. Larger blade capacity gets the job done in fewer passes.

Move More, Spend Less

Grade technologies help you work more precisely for faster results, less rework. Blade and undercarriage options help you take on the harshest conditions at a lower overall cost.
