That is, when the muddy soil for planting seedlings is hard, the biasing force is increased, the control sensitivity of the automatic lifting mechanism 39 based on the vertical swing of the float 13 is made dull, and the unevenness of the mud surface is suppressed by the float 13. At the same time, the float 13 is set in a forward upward position so that it can ride smoothly over the unevenness of the mud surface. On the other hand, if the mud is soft, the biasing force should be reduced to make the control sensitivity more sensitive.
The float 13 is set in a slightly horizontal position in order to improve the ability of the lifting mechanism 39 to follow the up-and-down movement of the float 13, and at the same time to avoid troubles such as disturbance of the mud surface due to sinking of the rear part of the float. The hardness and softness of the mud is detected by the sensor 44, and based on this, the biasing force is automatically adjusted and the float attitude is changed, so that the appropriate adjustment is made according to the hardness and softness of the mud. It has become possible to perform precise control with good operability.
