PROBLEM TO BE SOLVED: To make left and right implement parts as foldable toward a central implement part, and install crutches which are cut off automatically by a folding action. SOLUTION: This foldable agricultural implement separated into three parts of the central implement part 4, and the implement parts 5L, 5R at both left and right sides, linking inner end parts of the implement parts 5L, 5R with the side end part of the central implement part 4 by a rotary supporting member 6 as rotatable by approximately 180°, and making them as foldable by overlapping the back surface of the central implement part 4 with the back surface of the left and right implement parts 5L, 5R is provided by (1) installing crutches 11, 12 which transmit a power from the central implement part 4 to the left and right implement parts 5L, 5R when the left and right implement parts 5L, 5R are extended in their working positions relative to the central implement part 4, and cut off the power when the left and right implement parts are folded. (2) The crutches 11, 12 become automatically a connected state when the left and right implement parts 5L, 5R are extended in their working positions relative to the central implement part 4, and become automatically a cut off state when the left and right implement parts 5L, 5R are folded.
