A rice planting machine configured in such a manner that a ground leveling rotor drive structure for taking out power to the ground leveling rotor (80) side can be disposed at low cost. A rice planting machine provided with: a travel machine body (1) on which an engine (21) is mounted; a seedling planting device (2) mounted on the rear side of the travel machine body (1) with a lifting/lowering link mechanism (67) provided therebetween; a rear axle case (33) on which left and right rear wheels (4) are mounted with left and right rear wheel axles (43) provided therebetween; a ground leveling rotor (80) for leveling off the surface of the field in which the planting is to be performed; and a distribution shaft (91) for transmitting rear wheel travel power to the left and right axles (43). The rear axle case (33) has formed therein an input shaft case section (43a) to which a rear wheel travel input shaft (75) is provided, left and right final gear case sections (43b) to which left and right axles are provided, and a side clutch case section (43c) to which the distribution shaft (91) is provided. Power is transmitted to the ground leveling rotor (80) through the ground leveling rotor drive shaft (85). A drive shaft case section (43d) is formed in the rear axle case (33), a ground leveling rotor drive shaft (85) is provided to the drive shaft case section (43d), and the drive shaft case section (43d) is provided under the input shaft case section (43a) in a double tier arrangement. |
