In this way, by separating the fertilizer application device from the work position to the non-work position, the maintenance work of the fertilizer device can be performed without being disturbed by other devices or structures arranged near the work position. It can be done easily.

According to the first aspect of the invention, the fertilizer application device can be moved up and down between the working position and the non-working position separated upward by the lifting mechanism. In addition, the fertilizer does not protrude largely in the lateral direction from the range of the rice transplanter with the fertilizer.

According to the first feature of the present invention, when the fertilizer is moved between the working position and the non-working position separated upward by the lifting mechanism, the fertilizer is moved while maintaining the posture at the working position. Since the fertilizer can be operated, the fertilizer in the fertilizer storage hopper of the fertilizer does not fall out when moving the fertilizer, and it is necessary to take out the fertilizer from the fertilizer storage hopper of the fertilizer for the moving operation. Absent.

[II] According to the feature of the first aspect, in the fertilizer that feeds the fertilizer to the field along a plurality of planting strips, the non-working apparatus in which all the fertilizers of the planting strips are simultaneously separated from the working position and upward. Since the moving operation can be performed over the position, the labor required for the moving operation is reduced as compared with a configuration in which the moving operation is performed for each part of the planting strip. In this case, the elevating mechanism is provided on the right and left sides of the fertilizer and the left and right elevating mechanisms are arranged at a slight interval. When the moving operation is performed over the non-working position, even if the left and right widths of the fertilizing device are wide, the fertilizing devices of all the planting streaks can be stably moved.
