PROBLEM TO BE SOLVED: To simplify a structure and to reduce a cost in a riding-type direct sowing machine especially used in a region in which the possibility of seed rice being eaten by a bird or the like is low. SOLUTION: The riding-type direct sowing machine is constituted as follows. A float 9 is supported around a horizontal shaft 77 in the right and left direction of a supporting frame 48 of a direct sowing device so as to be freely turnable in the upper and lower direction. A fertilizer-feeding part 17 for feeding fertilizer to a groove while forming the groove on the paddy field surface is attached to the float 9 so as to be positioned at the vicinity of the horizontal shaft 77 in the side view. A seed rice-feeding part 12 for feeding the seed rice to the groove while forming the groove on the paddy field surface is attached to a part of the float 9 separated to the front or rear side from the fertilizer-feeding part 17.
