Abstract: The ridge raising operation is the key part of Puerarialotobaplanting production. The ridge raising height needs to be more than 50 cm, and the existing rotary tillage ridge does not meet the requirements. Based on the analysis of the existing rotary tillage ridgerin China,this paper puts forward the technical scheme of the rotary tillage ridger for Puerarialobata, which integrates deep rotary tillage and high ridging operation, and designs a new rotary tillage ridger for Pueraria planting. The machine can complete deep rotary cultivation and ridging at one time. It has the advantages of reasonable structure, stable work, high production efficiency, low operation cost, etc. it can meet the requirements of deep rotary cultivation and high ridging operation of Pueraria planting, and is suitable for the use of the vast Pueraria planting households, cooperatives and agricultural enterprises.
