Round disc rake is an agricultural machinery mainly used for tillage and soil preparation. It consists of multiple circular steel plates installed on the shaft, which rotate, cut, and loosen the soil under the traction of the tractor. The design of the disc rake enables it to effectively break up soil lumps, remove weeds, and mix crop residues, helping to prepare for sowing or other tillage activities.

According to different purposes and designs, disc harrows can be classified into light, medium, and heavy types. Heavy duty disc harrows are suitable for deep plowing and handling harder soils, while lightweight disc harrows are suitable for surface loosening and shallow plowing
