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 percent more productivity without consuming more fuel, as well as unprecedented ease of operation. Added blade capacity, increased power and steering performance, and a full range of technology options help customers realize more productivity and a faster payback.
The new D8T moves up to 18 percent more material per hour than the previous model, while using about the same amount of fuel, representing a significant fuel efficiency gain. In lighter applications, customers can expect to see up to 11 percent fuel savings compared to doing the same work with the previous model.
Much of the productivity gain comes from a new Caterpillar designed 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.
The Semi-Universal (SU) blade capacity has been increased by 19 percent. At 13.4 cu. yd. (10.3 cu. m), the largest SU blade in the size class finishes jobs in fewer passes. Optional patented Performance Cutting Edges increase blade payload by up to 25 percent versus standard cutting edges, especially in hard/frozen ground or heavily compacted materials.
Powered by a Cat C15 ACERT engine, the new D8T offers class-leading 354 net hp (264 kW). Drawbar power is increased by up to 13 percent. A 10 percent increase in steering torque, fully automatic transmission and differential steering combine to provide best-in-class steering performance under load.
