D8 - 21B, 2022, EU, ANZ, North America, Korea, Turkey
Overview
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.

Benefits & Features
MOVE MORE WITH LESS FUEL
- Move up to 18% more material per hour without burning more fuel in most applications.
- Save up to 11% fuel in lighter applications.
- Fully automatic 4-speed powershift transmission optimizes the dozer for maximum productivity and efficiency.
- 19% larger standard Semi-Universal (SU) blade moves more material per pass.
- Transmission puts up to 13% more drawbar power to the ground.
- 10% increase in steering torque, fully automatic transmission and differential steering combine to provide best-in-class steering performance under load.
- Optional FirstCut™ cutting edges increase blade payload by up to 35% compared to standard cutting edges.
EASY TO OPERATE
- Fully automatic 4-speed transmission - just select desired ground speed and the tractor will automatically manage settings for maximum efficiency and power based on load.
- No need to upshift/downshift - saves effort for experienced operators and helps newer operators maximize productivity more quickly.
- Added gear between first and second ensures seamless lock-up clutch engagement for exceptionally smooth shifting.
- All speed and turning input is packaged in a single hand control for easy operation - thumb wheel puts easy on-the-fly ground speed changes at your fingertips.
- Automatic Ripper Control and new rip-to-depth feature help reduce operator fatigue and machine wear and tear.
- Engine Idle Shutdown Timer shuts the machine down after a pre-set idling period to save fuel and reduce unnecessary idling time.
- Emissions reduction technology is designed to work automatically in the background while you work.
TECHNOLOGY THAT GETS WORK DONE
- Hit target grade faster and more accurately with Cat Grade technologies. Finish jobs in fewer passes, and with less operator effort, saving you time and helping you increase profit.
- Cat Grade with Slope Assist™ automatically maintains pre-established blade position without a GPS signal. (Single Tilt machines only).
- 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.
