TECHNOLOGY THAT GETS WORK DONE

The next generation motor grader offers updated Grade technology displayed on the 254 mm (10 in) color touchscreen option (LVR) or 203 mm (8 in) touchscreen display (JOY).
Use the Digital Blade Slope Meter to get to grade without relying on manual grade checkers.
Cat Grade with Cross Slope Indicate option provides a real-time readout of cross slope and can be scaled 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.
VisionLinkTM can help you monitor, track, and manage your road grader through sharing data and results with the organization.
Update machine software with Remote Services without taking the machine out of service.

BUILT-IN SAFETY FEATURES

The heated lens keeps the rearview camera clear.
In the event of an engine stall, count on the secondary steering system to turn on to help you stop the machine safely.
Ensure three points of contact when entering and exiting the machine with strategically placed walkways and grab rails.
Ground level engine shut-off switch stops all fuel to the engine when activated and shuts down the machine.
See the rear of your machine with connecting windows.
Work past sundown using the LED light option for increased night time visibility.
Keep your work site safer with Cat Grade technology, which reduces the need for manual grade checking with working machines.
Choose the optional 4-point safety harness for added operator safety

LOWER MAINTENANCE COSTS

Filters, such as fuel, engine air, and oil filters, are grouped together for easy access and preventative maintenance.
The next generation filters help reduce 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 reductions in maintenance costs 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.
