D4
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.
BUILT TO PERFORM
- 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.
DESIGNED FOR OPERATORS
- 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.*
* Please consult your Cat dealer for regional availability.
MOVE MORE WITH LESS FUEL
- 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.
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 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.
BECAUSE UPTIME COUNTS
- 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.
PURPOSE BUILT SPECIALTY MODELS
- 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.
