PROBLEM TO BE SOLVED: To provide a riding rice planting machine for solving the problem of a planting working machine in which: because devices and mechanisms such as a horizontal device and a lifting mechanism are arranged near the center part of the planting working machine, when an electric actuator unit for lifting up/down a soil preparation device is arranged near the center part of the planting working machine, the total length of the planting working machine becomes long as a gap between a driving machine and the planting working machine lengthens.SOLUTION: In a riding rice planting machine, a scrape amount adjusting lever 71 and a planting depth adjusting lever 72 are arranged on one side of a pair of stays 33, 35, namely on the stay 35 side, with respect to a lifting mechanism 9, and an electric actuator unit 61 is arranged near the stay 33 on the other side, opposite to the stay 35 side at which the scrape amount adjusting lever 71 and the planting depth adjusting lever 72 are arranged, with respect to the lifting mechanism 9.COPYRIGHT: (C)2014,JPO&INPIT【課題】植付作業機の中央部付近には、水平装置や昇降機構などの装置や機構などが配置されているため、整地装置を昇降させる電動アクチュエータユニットを植付作業機の中央部付近に配置すると、走行機体と植付作業機との間隔が長くなり、乗用田植機自体の全長が長くなってしまう。【解決手段】掻取量調節レバー71及び前記植付深さ調節レバー72を、昇降機構9に対して一対のステー33,35の一方のステー35側に配置し、電動アクチュエータユニット61を、昇降機構9に対して掻取量調節レバー71及び前記植付深さ調節レバー72が配置されたステー35側とは反対の他方側のステー33の近傍に配置した。【選択図】図3
