The first step in the design process was to estimate the system capacity. Assuming a ground speed of 5.2 km/h and soybeans planted in rows with 76.2 cm spacing and with a projected yield of 4.04 tonnes/ha, the conveying rate for
soybean grains was projected to be 1.84 tonnes/h. With a 50% content of MOG and a safety factor of 2.5, the final system
capacity was 9.07 tonnes/h. This safety factor was deter- mined by considering factors such as ground speed, yield, and driving conditions
