PROBLEM TO BE SOLVED: To improve the workability for forming a groove in a paddy field surface in a working vehicle for a paddy field. SOLUTION: The working vehicle for the paddy field is constituted so that a land-leveling device 37 and a groove-forming member 99 may be freely lifted and lowered to a first operation position A1 at which the land-leveling device 37 and the groove-forming member 99 contact with the paddy field surface G, a second operation position A2 at which the land-leveling device 37 is positioned higher than the paddy field surface G and the groove-forming member 99 contact with the paddy field surface G, or a housing position A3 at which the land-leveling device 37 and the groove-forming member 99 are positioned higher than the paddy field surface G.
