    • 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, fine grading, 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.
          
    • Standard 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.
    * Input reduction based on product testing of a D5 (17B) Next Generation Dozer with and without the use of Slope Assist in a side slope application. Inputs measured as number of times operator adjusts controls, collected and verified by electronic control module (ECM). Test conducted by Caterpillar at Washington, IL, in July 2022.
    **Feature not operational indoors or in areas where a GNSS/GPS signal is not available.
