せればよいため、従って操作が簡単かつ容易である。Functions and Effects of the Invention When attaching the tilling blade (41) to the tilling shaft (1), instead of fitting the tilling blade into the holder and fastening it with bolts and nuts as in the above problem, it is necessary to attach the tilling blade (41) to the tilling shaft (1). Cultivating blade (4)
All that is required is to fit the mounting base (3) of and insert the locking pin 5), so the operation is simple and easy.

固に支持される。In addition, during tilling work, the tilling blade (4) is pressed in the counter-rotational direction by the resistance of the soil accompanying tilling, so the tilling blade (4) has a disc body ( 2)
It will engage in a wedge-shaped manner with the wedge-shaped slope part (a) (a) of the mounting base (3), so that the inner surface of the mounting base (3)
Even if there is a gap between the tiller blade (4) and the side portions (b) and (b), the tiller blade (4) is firmly supported by the disc body (2) without wobbling.
