In order to improve the adaptability of row spacing, a new type of corn harvester with reel star wheel harvester head was developed. The corn harvester head was composed of the star wheel, the screw roller and stalk pulling roller. The star wheel had six fingers, and the screw roller could lift tilting corn and feed the corn in the picking device. And the stalk pulling roller were designed by analyzing the conditions of maize not pushing to break and single continuous feeding. Finally the performance of the corn harvester head was tested when working along row or inclined row or vertical row in field. The results showed that the corn harvester head could work along row or inclined row or vertical row, and the adaptability of row spacing was improved largely, when the operation speed was 1.1~1.5 m/s, star wheel speed was 50 r/min, lifting import roller speed was 1300 r/min, and stalk pulling roller rotate speed was 1050 r/min. 
