Abstract. Corn harvest is the key link in maize mechanized production process. At present, the commonly used maize picking structures have roller type and the spike plate. The picking performance of the spike plate mechanism is mainly affected by the structural parameters such as the shape of the rollers and the edge of ear stripper plate. Based on the existing 4-blade and 4-edge snapping rollers to design rollers with reverse-mounted pull stem cutter, a comparative experiment which the parameters are evaluated by the rate of grain loss and the rate of bract included was carried out. The results showed that different installation methods of the pull stalker have no significant effect on rate of bract included, but it is significant for the grain loss rate.
