[0002] The existing weeders mainly cut stubble by a spiral knife fixed to a knife shaft. However, when the spiral knife is cutting the grass on the surface and the rhizomes under the surface, the spiral knife, due to its unique spiral shape, will cause the grass and rhizomes to entangle on the spiral knife edge, making it impossible to cut them thoroughly. In particular, some grass and rhizomes are more resilient and grow vigorously, which are more difficult to cut and will also entangle on the knife shaft. The more they accumulate, the higher the failure rate of the weeder will inevitably be, affecting the operating efficiency of the weeder.
