The ecosystem of grassland in China is degraded now. The situation should be changed as soon as possible. It is the key to achieve sustainable development. The type of grass in this paper is leymus-chinensis L (L-C.), which is the main grass in the north of China. The design is based on a device for mechanical remediation of degraded grasslands. The device is called 9QP-830 grassland soil-gashing and root-cutting device. The rhizomes of L-C. can be cut by the cutting machine with a high rotary speed, so the permeability of the grass land can be better. Some problems were found through the field trails. The tool shaft was easily bended and cutting blades were easily broken. In this study, the optimized design was developed, which included the design and research of independent profiling mechanism and the depth controlled wheel. In the meantime, software such as CATIA and CAXA were used to aid drawing the machinery. The optimized design of this machine can improve the function and effect of root cutting.
