Net Power - Rated - ISO 9249/SAE J1349354 HP (264 kW)
The new Cat® D8T dozer 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 new bulldozer offers unprecedented ease of operation as well. A new 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.

Note (1)Net power at 1,900 rpm. Net power advertised is the power available at the engine flywheel when the engine is equipped with a fan, air cleaner, clean emissions module and alternator. Advertised power is tested per the specified standard in effect at the time of manufacture.
Note (2)All non-road Tier 4 Interim and Final, Stage IIIB, IV and V, Japan 2014 (Tier 4 Final) and Korea Tier 4 Final diesel engines are required to use only Ultra Low Sulfur Diesel (ULSD) fuels containing 15 ppm EPA/10 ppm EU (mg/kg) sulfur or less. Biodiesel blends up to B20 (20% blend by volume) are acceptable when blended with 15 ppm (mg/kg) sulfur or less ULSD. B20 should meet ASTM D7467 specification (biodiesel blend stock should meet Cat biodiesel spec, ASTM D6751 or EN 14214). Cat DEO-ULS or oils that meet the Cat ECF-3, API CJ4, API CK-4 and/or ACEA E9 specification are required. Consult your OMM for further machine specific fuel recommendations.

  • 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.
  • New 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 Performance Cutting Edges increase blade payload by up to 35% compared to standard cutting edges.

  • 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.
