December 21 ~ 25 last year in Nanfeng County, Jiangxi Machinery Industry Bureau chaired a Nanfeng 100-4 harvester identification stereotypes. The machine through the seven harvest season trials and seven major improvements, basically in line with the production and promotion of the use of requirements. The study of valve reversing valve of this machine basically solved the problem of middle blockage theoretically and practically. The research on the stem of straw was successfully completed, and the loss of spike of TianTou was basically solved. The aircraft light weight, flexible operation, easy transfer, night operations, but also with less loss, laying more neat, more reliable work
