Cat GRADE Attachment Ready Option (ARO) gives you the connections that you need to add grade control technologies.
Stable Blade senses blade bounce before you to reduce manual throttle use and site rework.
Product Link™ provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes, and other machine data on demand through the VisionLink® online interface, which helps you improve jobsite efficiency with lower operating costs.
Update machine software with Remote Services without taking the machine out of service.
Safety
View your surroundings with the rear camera option to ensure the safety of you and those around you. The dedicated display can be always on to ensure a safe work environment.

Filters, such as fuel, engine air, and oil filters, are grouped together for easy access and preventative maintenance.
Be more environmentally friendly with the next generation filters to get up to 15 percent in reduced filtration costs.
Maintain roads with the standard drawbar circle moldboard with hardened circle teeth for increased durability.
For tight finish grading, consider the top adjust drawbar option for applications that require maximum accuracy. It offers up to 45 percent reduction in maintenance cost over the standard.
Hydraulic brakes are well oiled to keep them maintenance free.
Lower costly repairs to your circle and pinion with the Circle Saver.
Versatility
Improve the balance of your machine with the counterweight or push block for increased performance and efficiency.
