的とする。However, the management work along the contour line on the left and right sloping land is usually reciprocated, and the lateral displacement direction of the machine body is switched to the left and right by changing the traveling direction of the machine body. It will be. To do this, either attach auxiliary disks to the outside of the left and right wheels, or
Alternatively, it is necessary to replace the auxiliary disk on the outside of the wheel on the inclined lower side each time the traveling direction of the machine body changes. However, with the means for mounting the auxiliary discs on the outside of the left and right wheels respectively, it is necessary to purchase two auxiliary discs, which imposes an economic burden on the user, and the storage and work place It is inconvenient to carry. On the other hand, in the form in which one auxiliary disk is replaced, the above problems are relatively small,
There was a difficulty in handling because it took time to replace the auxiliary disk every time the traveling direction of the machine body changed. The present invention has been made in view of such an actual situation, and an object of the present invention is to make it possible to easily and quickly perform the replacement work in the form of replacing one auxiliary disk.

At this time, the auxiliary disc can be removed by pulling out the auxiliary disc from the axle portion while the connecting pin provided on the boss of the auxiliary disc is pulled out against the biasing force. To attach the auxiliary disk, insert the auxiliary disk into the axle part while pulling out the connecting pin provided on the boss of the auxiliary disk against the urging force, and then free the connecting pin near the predetermined connecting position. If the connecting pin is aligned with the pin hole of the axle portion, the connecting pin is automatically urged and inserted into the pin hole, and the connection is completed.
