D4 Track-Type Tractor

The Cat® D4 dozer combines excellent fuel efficiency with the power and precision to excel in a wide range of jobs. A balanced design and available technologies like Cat Grade with Slope Assist™ and Cat Grade with 3D make it the ideal finish grading tractor.



  • Cat C7.1 engine gives you reliable power and top fuel efficiency.
  • Optimized undercarriage – eight (8) bottom rollers and two (2) carrier rollers for smoother ride and excellent finish grading performance.
  • Wide blade helps get more work done in fewer passes.
  • Traction Control feature reduces track slip in poor underfoot or muddy conditions.
  • Variable Pitch Angle Tilt (VPAT) blade for more versatility, simpler adjustment.
  • Forestry/Agriculture arrangement is factory equipped with specialized guarding and features for working in harsh applications like forestry and land clearing.*

    * Please consult your Cat dealer for regional availability.


  • Intuitive, precise electro-hydraulic controls with sensitivity adjustment.
  • Liquid Crystal Display (LCD) places machine data, settings menus and more conveniently in front of the operator; Display for optional rear vision camera so no additional monitor is needed.
  • Easy maintenance with grouped service and diagnostic points.
  • Convenient ground level access to primary fuel filter/water separator.
  • Easy to transport without blade removal.
  • Foldable blade option.*

  • Eco Modes optimize engine rpm while maintaining ground speed, saving up to 18 percent fuel in lighter blade load applications like finish grading.
  • Auto Engine Speed Control reduces engine speed when idling for added fuel savings.
  • Engine Idle Shutdown Timer shuts down machine after specified idle time to help save fuel and meet idling regulations.


  • 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 to increase your profit.
  • Cat Grade with Slope Assist™ automatically maintains pre-established blade position without a GPS signal.
  • Updated Cat Grade with 3D offers greater speed, accuracy and flexibility. Factory-integrated system eliminates position sensing cylinders. Antennas integrated into the cab roof for better protection. More intuitive 10-inch (254 mm) touchscreen display is easier to use.
  • AutoCarry™ automates blade lift to maximize blade load, improve load consistency, reduce track slip.
  • Cat Stable Blade works with electro-hydraulic controls to complement the operator’s blade-control input to get better finish grades faster and with less effort.
  • Standard Slope Indicate displays machine cross-slope and fore/aft orientation right on the main display.
  • Factory Attachment Ready Option (ARO) simplifies installation of all brands of grade control system.
  • All Cat Grade systems are compatible with radios and base stations from Trimble, Topcon, and Leica.
  • Already invested in a grade infrastructure? You can install grade systems from Trimble, Topcon, and Leica onto the machine.
  • Product Link™ collects machine data that can be viewed online through web and mobile applications.
  • Access information anytime, anywhere with VisionLink® and use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve security on your job site.


  • Long service intervals and easy maintenance keep the machine up and running to help lower your owning and operating costs.
  • Large, hinged door on the engine compartment for easy access to all regular engine maintenance points.
  • Grouped pressure taps for quick testing and troubleshooting of the hydraulic system.
  • Lower service panel can be removed without tools providing quick access to inspect engine compartment and filters.
  • Ground level access to hydraulic filters and primary fuel filter/water separator.
  • Improved fuel filtration system.
  • Tool box to keep your tools and grease gun at hand.
  • Optional bracket mounts to rear of machine to keep a shovel handy.
  • Monitoring system with automatic checks at start up.
  • Robust and convenient modular design.


  • Equip your dozer from the factory with added protection to work in harsh applications like agriculture, forestry and land clearing.
  • Specialized guarding on the undercarriage, lift cylinders, fuel tank, winch, radiator grill and crank case.
  • Heavy duty cab and overhead sweeps.
  • LED lights for added visibility.
  • Hydraulic demand fan adapts to engine heat load and reverses to help prevent plugging.
  • Turbine air precleaner with screen to help improve filter life in high debris situations.
