And a plurality of rake teeth are axially and uniformly distributed on the rake tooth beams. By designing the spiral blades and the rake teeth, the purposes of flattening soil ridges and loosening soil are achieved, and during working, under the combined action of the spiral blades and the rake teeth, the soil is conveyed to the rear portion and the side portion of the cutter, and the soil is loosened. Therefore, when the cutter works, on one hand, soil carried by unearthed root stumps is reduced while ridges are leveled; on the other hand, broken roots caused by stalk removal action are reduced due to loose soil. The cutter needs small power for operation, and is simple in structure, high in working efficiency and good in operation effect.
