sources of yield map error
Sources of Yield Map Error
  • Unknown swath width
  • Time lag of grain through combine
  • GPS error
  • Multiple paths through combine
  • Surging of grain through combine
  • Grain losses
  • Sensor Calibration
sources of impulse yield sensor error
Sources of Impulse Yield Sensor Error
  • Grain Moisture
  • Grain Test Weight
  • Grain Temperature
  • Grain Cultivar
  • Grain Species
  • Contamination
    • Dirt
    • Plant oils, sap, etc.

basics of yield monitoring
Basics of Yield Monitoring
  • Possible Crops to Monitor
    • Wheat and other grains
    • Cotton
    • Potato and Sugar Beets
    • Beans
    • Rice
    • Specialty Crops
      • Grapes, Tomatoes, Carrots, etc.
yield mapping trailer
Yield Mapping Trailer
  • Measures change in weight in the trailer while allowing for comparison at different times.
  • Can be used for any crop that is loaded into a trailer continuously while harvested.
corn silage
Corn Silage
  • The drive shaft of the base unit powering the cutterhead, feedrolls, and front attachment, are instrumented with strain gauge torque transducers.
  • Cutting power is linearly related to material feedrate.
  • Material flow can be expressed as:
    • Fr(t)=Yi(t)Sp(t)W
