PROBLEM TO BE SOLVED: To provide a farm implement capable of suppressing the formation of difference in levels on a field surface, and improving the flatness of the field surface.
SOLUTION: The farm implement 11 is equipped with a tiller for carrying out tilling operation, and a first land-leveling body 41 and a second land-leveling body 46, for carrying out the land-leveling operation at the rear position of the tiller. Extendable land-leveling bodies 61 switchable between an extended operating state and a folded non-operating state are installed in the terminal parts in the right and left directions of the second land-leveling body 46 so as to be turnable through shaft parts 57. Passages 72 for muddy water through which the muddy water of the field flows are formed between the terminal parts of the second land-leveling body 46 in the right and left side directions, and the inner terminal parts of the extendable land-leveling bodies 61 in the extended operating state.
