Header Height Sensor

Understanding Header Height Sensors for Combine Harvesters

Header height sensors detect the position of the combine harvester header.

• Sensors improve harvesting data quality by starting/stopping yield data recording based on the position of the combine header.
• They also help maintain optimal cutting height for different crop types and protect the header from damage by adjusting to uneven terrain

Extra added value for FieldView users:

• When mapping yield for the same field with multiple combines, one of which not equipped with header height sensors
• When mapping yield for the same field with multiple combines, one of which equipped with the Yield Kit without header height sensors.
  

The box is comprised of the following items:

• Sensor A master sensor body
• Sensor B remote sensor body
• CANbus M12 terminator
• CANbus M12 wire
• Sensor wire
• Alcohol swabs
• Y-split (only for retrofit version)

How it works

• Each sensor contains an inertial measurement unit (IMU) which can determine the sensor’s orientation relative to the ground.
• Sensor A is mounted to a fixed point on the combine frame, Sensor B to the feeder house.
• The Header Height Sensor must be mounted so that one of its axes is parallel to the axis running through the front axle of the combine (yellow line).
• Once calibrated, the relative angle between Sensor B and Sensor A is used to determine the height of the combine header. Using the relative angle, it can still function even when the combine is going up, down or on sidehills.
