The effects of the type of the snapping rolls of the harvester on harvesting performance are significant. For the vertical corn harvester, the effects of the type of the snapping rolls on harvesting performance were studied through orthogonal test, while the movement parameters of the interaction were analyzed, to determine the optimal production conditions. The pattern and shape of snapping roll on loss rate is significant; the roll of dome pattern under the conditions of 1000r/min can achieve the best results. The influence of roll shape on power is significant; the roll of dome pattern under the conditions of 900r/min can achieve the lowest power consumption. The relationship between working gap of snapping roll and loss rate is linear.
