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.
