変更との関連構成が複雑となる。Conventional technology and problems to be solved by the invention In mobile agricultural machines such as seedling transplanters that plant seedlings at a constant depth below the soil surface, it is difficult to maintain a constant height of the vehicle body relative to the soil surface. In order to do this, a lifting device is provided to move the running wheels up and down relative to the vehicle body. However, when the soil surface is in the form of ridges and grooves, it is necessary to change the tread so that the running wheels rotate in the grooves. The structure related to the lifting device and the tread change becomes complicated.
