With the above-described configuration, in the rice transplanter with the fertilizer device in which the hopper 30 is disposed behind the seat 9 and in front of the planting section 4, the hopper connection particularly in the case of 5-row planting and 6-row planting There is a valid point in the configuration. That is, when removing the fertilizer remaining in the central hopper, the seat 9 is located in front of the hopper and there is no fertilizer removal space, so that the fertilizer is moved into the left and right hoppers and removed from the left and right sides. In this case, in particular, the five-row planting and 6
In the case of row planting, the hopper 30 is provided with a fertilizer reduction sensor 30.
Since the fertilizer can be displaced and moved on the gentle slope 30'e to which the s is not attached, it is easy to take out the fertilizer on the center side (the fertilizer is displaced and moved on the steep slope 30'd). In other words, the inclination is steep and it is difficult to move, and it is difficult to catch the fertilizer reduction sensor 30s attached to the surface.)

Further, a funnel-shaped front, rear, left and right inclined surfaces 30'c, 3 'provided on the bottom side of each single hopper 30'.
