D6 Dozer

Powerful, Reliable, Durable

• Proven Cat® C9.3B engine eliminates Exhaust Gas Recirculation (EGR) system, updated fuel system, and simplification of electronic control modules (ECM) all contribute to a more reliable machine.
• Fully automatic 4-speed transmission continuously adjusts up or down for maximum efficiency and power to the ground without added operator input.
• Redesigned structure, with more weight and horsepower than D6T*, has configurations for you to build the machine for the work you do. Variable Power Angle Tilt (VPAT) tractors with improved range of motion for balanced, high-speed grading or robust Push Arm dozers for heavier applications, larger blades, and optional FirstCut™ cutting edges (SU blades only) for increased payload.
• Heavy Duty Extended Life undercarriage
   - HDXL with DuraLink™
   - features Positive Pin Retention (PPR2) pins and link improvements for more seal life in high impact conditions.
• Cat Abrasion™ undercarriage is a low cost-per-hour solution for high abrasion and low impact jobsites. The design offers double the seal life and eliminates bushing turns, reducing your costs per hour compared to traditional undercarriage. Reduces link scalloping for smoother operation.
• Improved structures for HDXL and Cat Abrasion undercarriage enable changes from one to the other.
• Common sprocket mounting style as other dozers, with segments on the outside of final drive improve serviceability.
• Purpose-built Waste and Forestry/Heavy Duty arrangements.

* Comparison for weight is between the standard configuration operating weights for the D6T and the D6 20C. Horsepower comparison is between the maximum engine horsepower for the D6T at 1,200 rpm and the D6 20C at 1,300 rpm.

Technology Made Simple

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.

• Optional Assist features can reduce operator inputs up to 45%.* Cat Assist with Attachment Ready Option (ARO) features include:
  • Attachment Ready Option (ARO) provides wiring and mounting provisions for dealer installation of Grade with 3D, Accugrade, UTS, or other grade control systems.
  • 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 up to 75%. No GNSS/GPS required.
  • Stable Blade works seamlessly with operator inputs to help produce a smoother surface when operating manually.
  • Slope Indicate is included in the main machine display and shows side slope and uphill/downhill grades to help operators with slope work.
  • 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.**
  • 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.**
• 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 ProductLink™.
• 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 GPS signal is not available.
