Cutting performance, reliable work, adaptability is strong. This design uses the gasoline engine as power, the weight is light, convenient farmer friend fields harvesting, greatly reduce the labor intensity of farmers. This machine adopts a vertical cutting platform of rice and wheat crops stalk after cutting, cut in the side of neatly stacked. The small rice and wheat Reaper machine has the advantages of simple structure, convenient operation, can effectively complete the wheat and rice harvesting task.Key word: The reaper; Reciprocating cutter; Vertical table; Divider
