SONIC TRACER/SLOPE SYSTEMS
A sonic tracer and cross-slope sensor system is available for use with Bobcat’s larger grader attachments. Where the laser-guided systems require a laser transmitter, and can only follow a plane of light, the sonic/slope system will follow the terrain below the sonic tracer and maintain a consistent, predetermined cross-slope.
This system also works well on jobsites where obstacles prevent visibility between the transmitter and receiver required for laser-guided systems.
Scan the code and watch Bobcat blade automation systems in action.
Sonic Tracer/Slope Sensor Features
or standard measurements
of blade and display actual cross-slope of blade
“rebench” sonic tracer
Automatic Modes - Fully Automatic: sonic tracer and slope sensor each move one side of the blade
Manual Mode: operator controls both sides of blade manually

for sonic tracer
- Semi-Automatic: Manually operate one side of the blade while cross-slope is controlled automatically
When the sonic tracer is disabled, the system is also capable of operating only the cross-slope in automatic mode. Manually control the side of the blade on which the sonic tracer is mounted, while the cross-slope sensor automatically maintains the correct cross-slope across the blade. This is especially useful when making first passes to provide a smooth surface for the sonic tracer to follow on the next pass.
THE SONIC TRACER
Mounted on either side of the moldboard, the sonic tracer uses ultra sonic signals to maintain a distance between it and an object below, such as a stringline, previous pass, or curb and gutter. The sonic tracer only moves the elevation cylinder for the side of the blade on which it is mounted.
CROSS-SLOPE SENSOR
Mounted to the back of the moldboard, this sensor moves one side of the blade to maintain a set cross slope entered by the operator. The cross-slope sensor only moves the elevation cylinder on the opposite side of the sonic tracer.
AUXILIARY COMPONENTS
A rotation sensor and mainfall sensor provide correcting information to the slope sensor when traveling up or down hills or when the blade is angled.
The operator places the sonic tracer over the top of the object he wishes to use as a reference and sets the blade depth as needed.
