置。[Scope of claim for utility model registration] At the bottom of the planting section attached to the rear of the traveling aircraft,
The rotation shaft is supported with the shaft length direction as the left and right direction,
Floats for surface sliding are attached to the rear ends of a plurality of rotating arms provided on the rear side of the rotating shaft, and the rotation of the rotating shaft is restrained at an appropriate position. A rice transplanter is equipped with which the planting depth can be adjusted according to the vertical position, and the planting depth is adjusted according to the displacement of the central float among the floats, which moves up and down regardless of whether or not the rotation shaft is restrained. A rising/lowering control device for a rice transplanter that raises and lowers the attachment part relative to the traveling body in order to maintain a predetermined height above the rice field surface, wherein an elastic force is applied to the central float in order to suppress vertical movement of the float. An elevator control device for a rice transplanter, comprising: a float pressing member that applies a force; and means for increasing or decreasing the elastic force applied to the member.
