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.

Cat Grade with 3D option is factory-integrated grade control that helps you improve grading efficiency, accuracy and productivity. Automates blade movements in both fine grading and production dozing applications, reducing operator inputs by as much as 80%. Antennas on top of the cab eliminate blade masts and cables. Reduces need for grade checkers and staking, enhances safety and reduces labor costs.
Standard Slope Indicate displays machine cross-slope and fore/aft orientation right on the main display.
Gain even more productivity and reduce operator inputs with Auto Blade Assist, AutoCarry™ and Automatic Ripper Control.
Factory ARO Option provides optimal mounting locations, brackets, and hardware to simplify installation of an aftermarket grade control system.
All Cat Grade systems are compatible with radios and base stations from Trimble, Topcon, and Leica.
Already invested in a grade infrastructure? You can install grade systems from Trimble, Topcon, and Leica onto the machine.
Product Link™ collects machine data that can be viewed online through web and mobile applications.
Access information anytime, anywhere with VisionLink® – and use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve safety and security on your job site.

LOWER MAINTENANCE COSTS
