An Agleader cotton yield monitor was modified for use as a peanut yield monitor for harvest during the 2000 and 2001 season. A single pair of optical sensors was mounted on the vertical portion of the delivery chute between the air fan and basket. Because the Agleader console required a fan speed, a small box fan with a magnetic switch was used to generate the needed fan speed input to the console. The first seasons harvest resulted in severe pitting and scarring of a glass plate used to protect the sensors from peanut and foreign material abrasion. Even so, mean load absolute error was only 11.6 percent for 25 loads of peanuts harvested. For the second season, a deflection baffle and a small air circulation opening at the bottom of each sensor was made to prevent abrasion from peanuts and foreign material and to reduce dust build-up, respectively. Inspection of the sensors showed that the modifications did prevent pitting and scarring on the sensor covering and that the dust build-up was reduced significantly. Mean load error for two different fields harvested was 9.4 and 3.2 percent. It was determined that adjustments to the combine at the beginning of the harvest season increased the error in yield monitor readings. Once the machine is adjusted and the yield monitor calibrated to that setting, the Agleader yield monitor results were comparable to the results predicted by Agleader when used to monitor cotton yield.
