Overview

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.

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.

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.

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).

LOWER MAINTENANCE COSTS

High quality cartridge fuel filters are purpose-built to help keep your fuel system clean and extend injector life.
High debris engine filter (optional) has a pleated design for less plugging - especially ideal for waste, wood chip, other fine debris applications.
Reduce cost, add versatility with rear implement valves that accommodate either a ripper or hydraulic winch with no changes and no trade-off in performance.

BUILT FOR LONG TERM PRODUCTION

More robust structures provide the added durability to handle the increased weight and productivity.
Caterpillar exclusive Elevated Sprocket undercarriage gives you an added edge in machine balance, component Long Term Value and Durability and ease of service.
Heavy Duty Extended Life undercarriage, HDXL with DuraLink™, is designed to help reduce your operating costs with heavier bushings for up to 25% more wear life, especially in high abrasion conditions.

BUILT-IN SAFETY FEATURES

Rear vision camera and cylinder mounted mirrors are available to enhance visibility around the machine.
Powered Bottom Guard option enhances safety during clean-out.
Convenient steps, handles and guardrail help you get on and off the tractor with greater ease.
Ground level access to lighting switch.

WASTE HANDLING PERFORMANCE

Build or close cells, push trash or spread cover – Cat Waste Handlers are designed and built from the frame up to take on the challenges of landﬁll work.
Specialized guarding, striker bars and seals help protect against impact and airborne debris.
Bottom and Final Drive guarding helps prevent damage from wrapping debris.

TAKE COMMAND

Cat Command for Dozing offers remote control operation for enhanced safety and greater productivity.
Command uses line-of-sight (LOS) control with an over-the-shoulder console, or a non-line-of-sight (NLOS) option using the Cat Command Station to run the machine remotely.
