The 4YMB-2 self-propelled flax harvester, manufactured by Dezhou Chunming Agricultural Machinery Co., Ltd., is a mechanized harvesting equipment specifically designed for flax crops. It is suitable for pulling up flax and sesame plants during their yellow ripening stage, and evenly laying the flax stalks in the field for natural degumming (i.e.,dew-watering method: its core is the decomposition of gum through natural microbial fermentation), thereby achieving effective separation of flax fiber and core xylem.

The walking mechanism of this machine adopts hydraulic stepless speed regulation and four-wheel drive.
