PROBLEM TO BE SOLVED: To achieve the folding operation for a three-foldable rice paddy preparation tiller by use of electric power. SOLUTION: This folding rice paddy preparation tiller is constituted with three sections, namely, a central working body, a left side extended work body and a right side extended work body in which these extended work bodies are supported axially on both sides of the central work body so that they may be folded upward. A drive means capable of rotating forward and backward by an electric motor is set to an axial supporter and the extended work bodies are made folded to efficiently utilize the drive motion of the electric motor thereby providing the folding rice paddy preparation tiller of light weight and inexpensiveness.
