Abstract

The performance of two yield monitors was tested using two combines equipped with yield monitoring hardware in a field study. The data stream from the yield sensing element was sampled at 500 Hz and comparisons were made between the data recorded at high frequency and the processed result from the yield monitor. A calibration to determine the percent error as a function of mass flow rate could not be developed for either machine because inbound grain flow was not controlled as the data was recorded during normal field operations. Based on the similarities between the data collected here and that from previous studies, the precision of yield sensing hardware has significant room for improvement.
