In the above-mentioned known bifurcated stand 6, even if an attempt is made to operate the stand 6 during work in a field to bring it into a grounded state as necessary, as described above, the machine body is placed in the field. Since it sinks deeply, there is a problem in that the frame 5 and the field cannot be sufficiently spaced, and thus cannot be used as a stand.

The present invention solves the above-mentioned drawbacks by switching the side stand 7 made of a single bar member to the ground or non-grounded state on the front left and right sides of the frame 5. It is installed freely. Moreover, it is intended that the stand 7 can be remotely operated by the hand of the handle 2.

Therefore, when the single wheel management machine 3 is normally stored or placed on a truck for transportation, the main body stand 6 is mainly used to maintain a stable attitude of the machine body.
Further, when working in a field, it is an object of the present invention to provide a stand structure in which the unstable one-wheel management machine 3 can be stably used depending on its application by mainly using the side stand 7. And

[0007]

In order to achieve the above-mentioned object, the present invention runs on one drive wheel 1 and handles 2
In the one-wheel management machine 3 operated by, the main stand 6 having at least a bifurcated shape is mounted on the front part of the frame 5 on which the engine 4 is mounted so as to be switchable to a grounded state or a non-grounded state, and the left and right sides of the frame 5 are On the side,
The side stand 7 made of one bar is mounted so as to be switchable to a grounded state or a non-grounded state, and the main stand 6 and the side stand 7 can be remotely operated by the remote operation means 8 at the hand of the handle 2. It is characterized by

[0008]

With the above structure, the stand structure of the one-wheel management machine of the present invention can be used when the one-wheel management machine 3 is stored in a normal state or when it is loaded on a transportation truck and transported. The remote control means 8 is used mainly with the main stand 6 in a grounded state to stably maintain the body posture. Further, when the single wheel management machine 3 works in the field, the unstable single wheel management machine 3 is stably supported by mainly using the side stand 7 in the grounded state by the remote operation means 8. Therefore, the main stand 6 and the side stand 7 can be selectively used by the remote control means 8 according to the application.
