Cotton Yield Monitor Installation

• Sensor mounted on front and rear of chute
• Requires jig for easier installation
• Can monitor 1,2,4, or 6 chutes, accuracy better
  as more chutes are monitored
• Monitor mounts in cab
• GPS on roof of Picker

8
Cotton Yield Monitor Calibration

• Why calibrate
• Numbers meaningless if not calibrated
• Calibration similar in all cotton yield sensors
• Take known amount of harvested cotton and compare
  monitor reading to weight actual weight of
  cotton
• Yield monitor weight 3500
• Weight from truck scales 3200
• Calibration factor 3200/3500 0.91428
• Header Height Calibration
• Speed Calibration

Comparison of Cotton Yield Monitors

• Evaluated
• Agriplan
• Agleader
• Farmscan
• Mississippi State Yield Monitor
