Steps to prepare the machine for harvest

The last four steps will help as you prepare the machine for harvest. These calibrations will affect your yield and moisture maps, so they must be done accurately.

  1. Header Calibration.  The header calibration determines the logging area.  When the head reaches its set point, the area count will stop.  The set point for the head is crop type specific because different crops are harvested with different heads and at different heights, so make sure you calibrate for each crop type.
  2. Vibration Calibration. When doing the vibration calibration the head needs to be attached to the combine, and the separator needs to be on, and the RPM’s must be between 250-650 RPM’s or full throttle.  Since different crops use different heads, the vibrations calibration is crop specific like the header calibration, so multiple calibrations are required for multiple crops. During this process, the system is recognizing any natural vibrations that is seen by the flow sensor that could be mistaken as grain flow.  Remember, the vibration calibration is very simple and only takes a minute, but don’t forget it. It’s important!
  3. Temperature Calibration is the next, and it is a one-time calibration.  If the temperature is calibrated later in the season, it will affect your moisture calibration, and it will throw off your data that you have already recorded, so do it right away.  The temperature reading that the sensor is giving should be close to the actual temperature outside, but it may not be exact.  Enter an offset to make the temperature on the display correct.  A temperature calibration should be done while temperatures are stable. If the combine has been sitting the hot sun or operating for a while, it may have a higher temperature that is not ideal for the calibration.
  4. Distance Calibration is the last calibration and the final step before completing the preseason checklist. The distance calibration is for calculating area accurately.  Generally, a GPS receiver displays speed and position, but if GPS is lost, there can still be an accurate area count by knowing distance traveled and swatch width.  For the distance calibration, flag a known distance, for example 200 feet press start and begin driving.  While driving the distance, the system counts pulses and converts them to feet.  You will press stop when the vehicle crosses the end marker.  If the system says it drove 206 feet and it actually drove 200, enter that information.  Repeat the process until it is accurate within a couple of feet.
