AccuGrade Sonic

State-of-the-Art Control System

Enhance the performance of your motor grader with AccuGrade Sonic, a state-of-the-art grade control system designed to control surface elevation. The sonic system uses an ultrasonic sensor to maintain the blade at the same relative vertical distance to an external reference, such as a string line or curb and gutter.

Adjust Elevations Automatically

The system allows the operator to make automatic elevation adjustments when in the “cross slope only” control mode. The operator simply steers the machine to maintain the sensor over the external reference.

Single and Dual Sonic Systems

When combined with AccuGrade Cross Slope, the single sonic system provides automatic blade adjustments to one side of the blade for automatic control of elevation and cross slope.

When two sonic sensors are used, the system provides automatic elevation control to either side of the blade. The system typically uses only one sensor at a time. This allows the operator to control which side of the blade to control and change direction without relocating sensors.
