問題があった。In order to properly obtain the performance of the raising device and the weeding device, it is necessary to reliably hook the tine to the foliage. However, because the tines are securely hooked to the foliage, the torn foliage is likely to be generated, and in particular, those with a small breaking force of the foliage have more torn foliage, and the torn foliage is caught by the tine and carried around, and the tine case is carried. Not only is the appearance of the tines trapped and accumulated at the entrance, causing poor performance due to poor operation of the tines.Finally, clogging occurs, and the tines malfunction, resulting in inability to work or damage. Was.
