できる利点がある。Such a power working vehicle with a simple riding device is of course easier to construct economically than a tractor-type riding working vehicle, and since the riding device is self-propelled, it can be used even in fields with high running resistance such as wet fields and semi-wet fields. Even in a riding device, smooth and reliable running operation can be carried out, and the turning radius of the driving wheel in the riding device is small, and the driving wheel passes through the ground contact point and rotation axis of the riding device. By turning around the vertical axis, the positional fluctuation of the drive wheel ground contact part with respect to the main body due to turning can be eliminated or minimized, so even if turning with a small radius, the stability of the entire machine can be maintained. Although it is not a simple riding type, it has the advantage of being able to maintain its stability and make safe turns, and has excellent running and turning performance.
