Cat Grade Control System
The Cat Grade Control System brings to the customer an increase in productivity by up to 40 percent while reducing their site costs dramatically. The revolutionary Caterpillar® solution is factory integrated, sensor-independent, and features a suite of products, which includes cross slope, sonic, laser, GPS, and ATS technology.


We understand that productivity and our customer’s bottom line depend on moving material accurately, quickly, and safely the first time. Maintaining consistent grade is difficult, labor intensive, and challenging for even the most experienced operators. By combining digital design data, in-cab operator guidance features, and automatic blade controls, our Cat Grade Control System actually enhances grading accuracy and virtually eliminates the need for survey stakes.

Most importantly, Caterpillar is raising the bar in the industry by backing our solutions with our renowned, customer-centric worldwide dealer network.
Fine grade with greater accuracy and control with Cat Grade technology solutions for motor graders. Cat Grade begins with the basic cross slope system. System flexibility allows elevation control to be combined with cross slope control to meet a wide range of site-specific grade requirements.

Features and Benefits
Cat Grade delivers a wide range of customer benefits designed to: increase operator efficiency and productivity, improve accuracy, reduce material costs, reduce surveying and labor costs, and lower overall operating costs.

Cat Grade Sonic
The Sonic System uses ultrasonic sound waves and a sonic elevation sensor to measure distance and calculate elevation. The system features automated blade adjustments for automatic elevation control and built-in vertical guidance indicators for manual control.

Cat Grade Cross Slope
The Cross Slope System uses three machine-mounted sensors to calculate cross slope of the blade. The system combines automated controls with manual elevation adjustments to achieve desired cross slope.
Cat Grade Ready Option (ARO) Machine
The ARO machine simplifies system installation and reduces machine downtime. The AccuGrade system is designed and integrated into the machine systems and controls to optimize performance and reliability.

Cat Grade ATS
The ATS System uses an Advanced Tracking Sensor (ATS) with target recognition to track a machine and determine precise blade positioning. The system features fully automated blade adjustments for automatic elevation control.

Cat Grade GPS
The GPS System uses Global Positioning System (GPS) satellites to determine precise blade positioning. The system features fully automated blade adjustments for automatic elevation control, and vertical and horizontal guidance light bars for manual control.

Cat Grade Laser
The Laser System leverages laser technology to create an accurate grade elevation reference over the work area. The system features automated blade adjustments for elevation control with tight tolerances and built-in elevation/grade display indicators for manual control.
