Features At A Glance

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.
