PROBLEM TO BE SOLVED: To provide a weeder solving such problems that, in general, chemical weeding activities using agrochemicals have been conducted conventionally, but are not always good for human health and the environment; besides, as to physical weeding methods on the other hand, such weeders as to enable introduction into agrochemical-free agriculture in mild-seasoned districts lag behind in development. SOLUTION: The weeder is provided, being so designed that soil near the ground surface is agitated together with weed by high-speed rotation of a tractor rotary weeding tine body equipped with weeding tines formed of springy wires to crumble and embed the soil in the ground, thus improving the weeder's weeding capacity. Besides, the weeder is so structured that the worn springy wires can be easily replaced. Furthermore, this weeder is incorporated with such a mechanism that the weeding tine body can smoothly follow the unevenness on the weeding ground surface to reduce weeding activity loss.
