An airframe 1 is supported by a front wheel 2 and a rear wheel (drive wheel) 3 so as to be able to run, a handle 4 for walking is provided at a rear portion of the airframe 1, and a rear wheel 3 is provided. Is driven by the engine 5. The body 1 is provided with a ratchet 6 for carving a seeding groove A on the ground surface so as to rotate in a direction opposite to the rear wheel 3 against the traveling of the body 1, and the ratchet 6 is raised above the ratchet 6.

なったりする。On the other hand, especially in cold regions such as Tohoku and Hokkaido, the seeds are sown on the ground surface and are not covered with soil, or the cover is made thin (shallow planting) because oxygen is easily taken in or the germination rate is good. I understand that. In order to reduce the soil cover thickness, it is naturally conceivable to reduce the depth of the trench and reduce the amount of soil to be shaved, but there are large and small undulations in no-till fields.
Therefore, when the depth of the trench is made shallow, the amount of soil to be shaved varies greatly, so that an uncovered portion is formed or the thickness of the covered soil becomes unstable.

It has been found that the germination rate is better when the floor soil is removed, and that the octopus foot phenomenon that causes the lodging of rice can be prevented.
