[0002] The micro-tillage machine has the characteristics of light weight, small size and simple structure. It is widely used in dry land, paddy fields, orchards in plains, mountainous areas and hills. It can be equipped with corresponding machines for pumping water, generating electricity, spraying medicine, spraying and other operations. The micro-tillage machine is usually equipped with a wheeled traction walking mechanism to provide driving force for walking, which is convenient for users to use and store, and eliminates the trouble that large agricultural machinery cannot enter the field area. During the use of the existing micro-tillage machine wheeled traction walking mechanism, in order to ensure the walking stability of the operating micro-tillage machine, the span between the two walking wheels on the left and right sides for towing the micro-tillage machine is large, and because the distance between the two walking wheels is fixed, if the micro-tillage machine that is not in operation encounters a narrow ridge road condition when walking, it is difficult to ensure that both walking wheels are on the narrow ridge road surface, which is easy to cause inconvenience when walking on the narrow ridge road surface, affecting the applicability of the micro-tillage machine when walking on complex road conditions.
