The latest Cat D8T dozer is designed to move more material in less time, at a lower cost per ton, for a faster return on equipment investment. The bulldozer features an all-new fully automatic transmission, delivering up to 18% more productivity without consuming more fuel. Added blade capacity, increased power and steering performance, and a full range of technology options help operators realize more productivity.

Much of the productivity gain comes from a new fully-automatic 4-speed transmission. The powertrain continuously optimizes the dozer for maximum power and greatest efficiency based on the load. There is no need for the operator to upshift/downshift, so operators of varying experience levels can get the most from the dozer without having to manage gear shifts. The added gear and seamless lock-up clutch engagement ensure smooth shifting.

Powered by a Cat C15 ACERT engine, the D8T offers class-leading 354 net hp.  Drawbar power is increased by up to 13%. A 10% increase in steering torque, fully automatic transmission, and differential steering combine to provide best-in-class steering performance under load. 

Like all Cat dozers, the D8T is designed for easy routine maintenance with features like grouped service points and a ground level service center. New cartridge fuel filters, longer engine oil service interval, and standard programmable automatic reversing fan help save maintenance time.

The D8T is available in standard and low ground pressure configurations, as well as purpose-built waste and stockpile arrangements. A variety of blades and track shoe types/widths allows each machine to be optimized for performance in specific applications.
