Design and experiment on the dextral and laevogyrate helicoid cutting mechanism for no-till drills

, : Design and experiment on the dextral and laevogyrate helicoid cutting mechanism for no-till drills. Nongye Jixie Xuebao = Transactions Of The Chinese Society For Agricultural Machinery: 12, 69-72

A dextral and laevogyrate helicoid driven cutting mechanism was developed for no-till drills in the area of two crops a year of Hebei province. In the operation of the no-tillage wheat drill, the mechanism worked well, moving the residue from the row, cutting off the corn stalk and rootstalk, loosening the soil of the seedbed and opening the seed furrows.
