PROBLEM TO BE SOLVED: To provide a mowing cutter which gives a shock, friction, churning, and cutting, with the edged tool attached to a rotary disk, around grass roots spreading into the upper layers of soil or the topsoil, and plucks off the grass between ridges or roots of crops on a flat land and a dry field.SOLUTION: A plurality of mowing edges having the inclination and the centripetal force are mounted to steel disks attached to a shaft, so jolt is given to grass roots in topsoil simultaneously with rotation to pluck off the grass. Since the rotary edge has a diameter of 90 mm or so, grass between ridges or roots can be weeded, and moreover since a stabilizer is mounted, smooth operation is possible without vertical fluctuation.【課題】土壌上層部即ち表土に蔓延する草の根際に、回転する円盤に取り付けた刃物で衝撃、摩擦、撹拌、切断を与え、平坦地、畑地の畝、作物の株間の草を毟り取る刈刃装置を提供する。【解決手段】軸に取り付けた鋼製円盤に傾角と向心力を兼ね備えた複数の刃物を装着し、回転と同時に表土の草の根に衝撃等を与え草を毟り取る。回転刃は直径９０ｍｍ内外でできているので、畑地の畝、株間の除草ができ、しかも安定板を装着しているので上下動がなく円滑に操作できる。【選択図】図２
