In a rice transplanter provided with a fertilizer (36) extending in the left-right direction on the traveling vehicle (1), the hoppers (371) (3)
72) and the feeding cases (381) and (382) and the air tanks (421) and (422) are set on the vertical axes (126) and (14).
2) The hoppers (371) and (372) and the feeding cases (381) and (38)
2) and the air tanks (421) and (422) can be compactly folded at the same position inside the traveling vehicle (1) to reduce the left-right width, and the left and right sides of the traveling vehicle (1) without removing the fertilizer application part (36). The width can be easily changed, and the outer hoppers (371) and (372) and the feeding case (381) are provided.
(382) and the air tanks (421) and (422) can be easily shifted to the fertilizer application position or the folding storage position at substantially the same operation position, and the transport workability using a truck bed or the like can be easily improved. Can be done.
