This cutting body 20 is made of metal, heat-treated, and a pair of left and right symmetrically attached. And as shown in FIG. 2, the front-end | tip part of the cutting body 20 becomes the shape which started up upwards. Furthermore, as shown by the hatched portion in FIG. 3, the front portion of the cutting body 20 is provided with a cutting blade for cutting miscellaneous matters such as grass, and has a mountain shape with respect to the traveling direction.

Further, for example, a metal cutting plate attachment body 21 is detachably attached to the lower front side of the support frame 11 along the front end of the support frame 11. The cutting plate attachment body 21 includes a connection plate portion 23 having a connection hole such as a bolt insertion hole, and a slightly curved rectangular plate-shaped attachment plate integrally formed at the front end of the connection plate portion 23. Part 24.

Then, on the front surface of the mounting plate portion 24 of the cutting plate mounting body 21, while cutting the soil of the subsoil layer and the cultivating layer (an intermediate portion between the subsoil and the soil) with the movement in the traveling direction X, A cutting plate 26 such as a resin cutting plate, which is a divided work body for lifting the cutting soil to the vicinity of the ground surface G (near the soil layer) and lifting the cutting soil to the vicinity of the ground surface G (near the soil layer) is removable. The cutting plate 26 and the mounting plate portion 24 overlap each other and are in a laminated state.

Further, the cutting plate 26 is constituted by a relatively thin synthetic resin plate, for example, which has a shape corresponding to the mounting plate portion 24 and hardly adheres to soil. In addition, the cutting part 30 is comprised by the cutting plate 26 and the cutting plate attachment body 21. FIG.

Further, a reverse plate attachment body 31 made of metal, for example, is detachably attached to the front side of the substantially central portion in the longitudinal direction of the support frame 11 so as to be positioned along the front end of the support frame 11. The reversing attachment body 31 includes a connection plate portion 33 having a connection hole such as a bolt insertion hole, and a slightly curved substantially rectangular plate-shaped attachment plate formed in a cross shape integrally with the front end of the connection plate portion 33.
