Abstract: At present，row corn harvest technology has been basically mature in our country，but non row corn harvest technology has yet to be improved.A kind of mini amplitude modulation non row corn combine harvester matching with hand tractor was designed.This machine not only could achieve not row harvest，but also could adjust harvesting width continuously according to corn plant spacing and growth status.It could complete many works such as corn ear harvesting，corn ear collecting and corn straw returning to field.This mini amplitude modulation non row corn combine harvester played an important role in promoting corn non row harvesting mechanization realization in hilly and mountainous areas of our country.
