Workability of Tsukida planting machine was improved.

According to the first and second aspects of the present invention, when the fertilizer application device (the fertilizer storage hopper and the plurality of feed sections) is moved between the working device and the non-working device, the fertilizer device (the fertilizer storage hopper and the plurality of Since the fertilizer in the feed section of the feed does not spill out, there is no need to take out the fertilizer from the fertilizer (fertilizer storage hopper and feed section for multiple feeds) for moving operation. No waste is caused, and the occurrence of rust or the like due to the spilled fertilizer adhering to the metal part is also prevented beforehand.

According to the first and second aspects of the present invention, the fertilizer applicator (fertilizer storage hopper and a plurality of feeding sections) can be vertically moved between a lower working position and an upper non-working position. With this configuration, even in a relatively narrow place such as a barn, the fertilizer applicator (fertilizer storage hopper and a plurality of feeding sections) can be moved to the non-working position without hindrance. The workability of the rice transplanter can be further improved.

According to the features of claims 1 and 2, a plurality of fertilizers (fertilizer storage hoppers and a plurality of feeders) are connected and supported on a single support frame, and a plurality of fertilizers (fertilizers) are provided. Since the storage hopper and the feeding section for a plurality of rows can be moved at a time, the operability is improved.
