Cat D8 Dozer
THE RUNDOWN
NEXT GENERATION PERFORMANCE
- Fully automatic 4-speed powershift transmission continuously adjusts for maximum efficiency and power to the ground without added operator input.
- Next Generation cab for the D8 means common controls and interface for all D5-D8 machines, making operators more efficient across multiple dozers.
- Blades are right-sized to the machine to help you get jobs done in fewer passes.
- Elevated sprocket gives you better ride and balance, plus more penetration force.
- Long undercarriage is standard, with more track at the rear of the machine for superior dozing performance.
- Outfit your dozer from the factory to take on the challenges of slot dozing, ripping, and more.
OPERATOR HELPERS
Assist features help make work easier, especially for less experienced operators. Some blade and steering functions are automated so newer operators can work at productivity levels closer to their veteran counterparts. Seasoned operators can enjoy reduced effort and fatigue, along with faster, more accurate results.
**Feature not operational indoors or in areas where a GNSS/GPS signal is not available.
- Optional Assist features can reduce operator inputs up to 45%.*
- Cat Assist with Attachment Ready Option (ARO) features include:
- Stable Blade works seamlessly with operator inputs to help produce a smoother surface when operating manually.
- Traction Control automatically reduces track slip to save you time, fuel and track wear.**
- AutoCarry™ automates blade lift to help you maintain consistent blade load and reduce track slip.**
- Blade Load Monitor gives you real-time feedback on current load versus the optimal blade load based on your ground conditions. Actively monitors machine load and track slip to help you reach optimal pushing capacity. **
- Cat Grade with Slope Assist™ automatically maintains pre-established blade position without a GNSS/GPS signal – no additional hardware or software needed. For machines with 3D, operators can easily switch back and forth from full 3D automatics to Slope Assist.
- Steer Assist automates track and blade tilt steering. Helps reduce operator fatigue by automatically maintaining straight travel with light loads or heavy loads on flat ground and side slopes. Helps reduce steering inputs. No GNSS/GPS required.
- Slope Indicate is included in the main machine display and shows side slope and uphill/downhill grades to help operators with slope work.
- Attachment Ready Option (ARO) provides wiring and mounting provisions for dealer installation of Grade with 3D, Accugrade, UTS, or other grade control systems.
- AutoRip automates ripper raise/lower and shank in/out to maximize ripping productivity.
- Application Profile lets you save machine settings based on application or operator preference. Utilize any of the default profiles defined by our expert operators or customize profiles for various jobs or multiple operators.
- Operator ID allows you to save custom touchscreen setup, machine settings, and to track individual operator productivity, safety and training opportunities via Product Link™.
- Machine security – passcode helps prevent theft and unauthorized operation by requiring an operator to enter an ID to start the machine.
**Feature not operational indoors or in areas where a GNSS/GPS signal is not available.

HANDLE THE DESERT HEAT
- Choose from a variety of factory options to support machine performance and service life in extremely sandy or abrasive conditions.
- Cooling system designed for sand application with special fan coating and radiator grid.
- Turbine precleaner prevents particles from entering the engine system by delivering cleaner air to the powertrain.
- Sealed bottom guard and added seals help keep fine abrasive particles out of components. Access panels facilitate cleanout without removing bottom guard.
- Ducted and sealed alternator for longer life.
- Special seals throughout machine help reduce sand entering machine.
- Powered air precleaner helps keep cab air cleaner and pressurized for greater operator comfort.
- Solid-bottom engine enclosure doors help keep sand out for improved cooling and reduced cleanout.
- Specially coated fan and radiator core protection help resist abrasion. Reversing function is disabled on the hydraulic demand fan.
- Replaceable wear plates offer longer blade life when working in abrasive conditions.
CONNECT TO GREATER EFFICIENCY
