National rice planting area accounts for about 30% of the total area of food crops, nearly half of the total output of food crops production. And a large part of region is hilly areas, these places harvester inconvenient to use, most of them still use of human work productivity isnot high. So design a small, in the foothills of the harvest swather is particularly important. This article isa small swather power mapping and improved design. The power section to be able tobe used in conjunction with cutting table, cutting table move on their own power in the course of their work. Can effectively adjust the speed of field operations and adapt to different environments. Its main contents include transmission scheme, the dynamic part of the Dimensions of Surveying and Mapping, manipulation armrest, rear diesel engine, sprocket, pulley and bevel gear drive design, as well as the choice of gearbox.
