させる機構を設けてある乗用田植機に関する。[Detailed Description of the Invention] The present invention supports the aircraft on the ground by means of a propulsion wheel provided at one location in the front-rear direction when viewed from the side and three or more ground floats arranged laterally in parallel on the side of the planting device. In addition to being configured to allow planting to travel, an auxiliary support that can ground the planting device and support the planting device on the ground is provided in a vertically movable state, and is used to detect the ground pressure of the center float of the group of ground floats. Based on the above, the present invention relates to a riding rice transplanter provided with a mechanism for moving the auxiliary support body upward so that the float ground pressure is automatically maintained at a constant or approximately constant level.

い。In such a riding rice transplanter, it is necessary to ground the auxiliary support only when the mud is soft;
If it is possible to stably support the planting device on the ground using only a group of grounded floats, it is recommended to float the auxiliary support to the ground in order to prevent the auxiliary support from increasing movement resistance and disturbing the mud surface. It is desirable to switch to a positioned support configuration.

する状態に設けてあることを特徴とする。In view of this, the present invention makes effective use of the original function of the automatic vertical movement mechanism for the auxiliary support, and makes simple structural improvements by simply rearranging the ground pressure detection float.
The purpose is to automate the switching of support forms depending on the hardness and softness of the mud. The riding rice transplanter according to the present invention is characterized in that the ground pressure detection float is provided in such a manner that its lower surface is located slightly higher than the lower surfaces of the floats on both sides thereof.

させた支持形態に自動的に切換え得るに至つた。That is, by positioning the lower surface of the ground pressure detection float a little higher than the bottom surfaces of both floats, if the mud is hard and the amount of sinking of the ground float group is small, the ground pressure detection float By making the ground pressure zero or very small,
Since the above-mentioned automatic vertical movement mechanism can now be made to move the auxiliary support upward, an extremely simple structural improvement can be made by positioning the ground pressure detection float 5 higher than the floats on both sides. As a result, when the muddy soil is so hard that the planting device side can be supported on the ground only by the ground-contact float cart group, it has become possible to automatically switch to a support mode in which the auxiliary support body is placed in a floating position above the ground.
