A Study on Yield Monitoring System for Head-Feeding Combines (Part3)

Systemization of Data Acquisition, Analysis and Mapping

Abstract

A yield-monitoring system for head-feeding combines was developed and its usefulness was shown. The system monitors the yield using an optical sensor and a load cell, while simultaneously recording position information during harvesting using GPS. The system draws a yield map after analyzing the tailings return and operation width.
Using a head-feeding combine equipped with our system, it was possible to obtain yield information during normal fieldwork. The resulting yield map was equivalent to one obtained using quadrate sampling. The yield-monitoring error of our system was about 10%.
