Cat Grade with Cross Slope Indicate option provides a real-time readout of cross slope and can be scaled to Cat Grade with Cross Slope for automatic blade movement.
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.
