Radar sensor solution for precise ground clearance control of combine harvester cutterbars.

Precisely adjusting the height of the combine header or tractor implement is essential to ensure optimal and efficient fieldwork. Our radar sensor solution reliably measures the distance between soil and combine header. As a result, the radar system provides a highly precise and fast ground clearance monitoring – even in dust, fog, rain, vibrations or extreme temperatures. Since the driver no longer has to control the height adjustment of the header or cutterbar, a higher operational speed is possible. This leads to increased productivity when using the combine or tractor in the field.

With the robust OndoSense radar technology, you will achieve reliable measurement results even in the challenging conditions of farming. Benefit from our innovative radar technology for the precise ground clearance control of your combine harvester header!

Your added value with radar


Minimal maintenance costs with radar.

  • Reduced maintenance effort: Radar has no moving parts, works contact-free and requires almost no cleaning.
  • Our radar measurements are very stable over a long period of time, so that no time-consuming recalibration is required.


Fast & efficient harvesting operations.

  • Faster, more productive operations: The driver no longer has to control the height adjustment of the combine.
  • Thanks to precise measurements (±1 mm) with a high measuring rate (up to 100 Hz), our radar always provides precise height settings.


Measures error-free in any weather.

  • Our radar sensor is weather-independent and also measures in heavy dust, rain, snow, fog or difficult lighting conditions.
  • Radar measurements are not affected by wind or vibrations - unlike ultrasonic sensors.
