止される。 When rotary tilling work is performed using the tilling and crushing claws 7 configured as described above, the part A is roughly plowed by the machete claws 9 rotating with a turning radius R as shown in FIG. The surface layer B of the plowed soil is further finely crushed by the crushing member 23 rotating at a rotation radius R', and the surface is leveled by the tip edge 23a.
In addition, resistance is received from the soil due to tilling of the machete claw 9, and this resistance applies a load to the attachment part of the machete claw 9, but since the crushing member 23 protrudes from both sides of the machete claw 9, the attachment of the machete claw 9 is difficult. Since the load on the part is applied evenly in the axial direction of the tilling shaft 1 and is not concentrated on one side, the bolt through hole 21
The fastening force of the bolt inserted into the bolt is unlikely to weaken, and therefore the attachment portion of the machete claw 9 is prevented from rattling or falling off.

ができる。 As can be understood from the above description of the embodiments, the gist of the present invention is as described in the claims for utility model registration. Even when subjected to resistance, it rotates smoothly and in a well-balanced manner with the tilling claws, and the surface layer of the tilled soil that has been roughened by the tilling claws can be further finely crushed by the crushing member. It is possible to improve performance and work efficiency. In addition, the tip of the crushing member is parallel to the direction of the axis of the tilling claw and is wide and protrudes from both sides of the tilling claw, so it rotates smoothly and in a well-balanced manner even when subjected to soil resistance.
The soil in the surface layer can be transported well, and the soil surface can be leveled. Furthermore, since the crushing members protrude on both sides of the tilling claw, the load due to the resistance of the soil is applied evenly in the axial direction of the tilling shaft at the attachment position of the tilling claw, so it is not concentrated on one side. The fastening force of the tilling claws to the tilling shaft is unlikely to weaken, and therefore, it is possible to prevent the tilling claws from rattling or falling off from the tilling shaft.
