PROBLEM TO BE SOLVED: To provide an agricultural work vehicle which can be suitably used for keeping a definite tilling depth and achieving a highly accurate leveled surface necessary for the puddling work, etc., of a paddy field. SOLUTION: Provided is a puddling machine 1 provided with a rotary working part 13 attached to a traveling machine body, moving by the traveling motion of the machine body and rotating by the power transmitted from the traveling machine body. A shield cover 15 is placed above the rotary working part 13, an apron 29 is attached to the rear end of the cover in a vertically tiltable manner, a leveler 31 is attached to the rear end of the apron 29 in a vertically tiltable manner, a leveling board 23 is extended at the front side of the rotary working part 13 from one end to the other end of the width of the machine body and supported in a vertically movable manner, and an unevenness detection sensor 25 to detect the height of the unevenness of the field by the vertical motion of the leveling board 23 is attached to a link member 19 to movably support the leveling board 23. The apron 29 can be rotated by a rotation cylinder 51, and the action of the rotation cylinder 51 is controlled by a rotation controlling device 60 based on the detection value obtained by the unevenness detection sensor 25 to adjust the inclination angle of the apron 29.
