PROBLEM TO BE SOLVED: To provide an agricultural implement without causing inconvenience such that crutch fitting is not released by an effect of attached soil. SOLUTION: This agricultural implement 1 is equipped with a central implement main body 2 and left and right foldable implements 3 installed as freely rotatable at the implement main body 2. At the implement main body 2, one side crutch 11 is installed, and at the foldable working bodies 3, another side crutch 20 is installed for fitting with the one side crutch 11. The agricultural implement 1 is equipped with a driving means 21 for rotating the foldable working bodies 3 relative to the implement main body 2, and an extension-locking means for locking the foldable working bodies 3 at an extended working position. On releasing the lock by the extension-locking means, the foldable working bodies 3 rotate a bit from the extended working position to the folded direction by an elastic recovering force of an elastic body 43 for assisting the release of the crutch fitting.
