PROBLEM TO BE SOLVED: To provide a technique for securing the transmission of driving power to a ground-leveling device without installing a single-purpose PTO driving mechanism in a transmission case in a rice transplanter equipped with the ground-leveling device for leveling a field surface by rotational motion at the front side of a transplanting part.SOLUTION: The structure for taking out the rotational driving power of the ground-leveling device 51 from a rear axle case 11 for supporting the drive of rear wheels 12 is adopted. The driving power is transmitted to the ground-leveling device 51 by branching the power from an intermediate shaft (a rear intermediate shaft 24) at the upstream side of the power transmission based on a final transmission shaft (a rear axle 14) for driving the rear wheels 12 in the rear axle case 11.COPYRIGHT: (C)2009,JPO&INPIT【課題】植付部の前方に、回転運動によって圃場面を均す整地装置を具備した田植機においてミッションケース内に専用のPTO駆動機構を設けることなく整地装置への駆動伝達を確保するための技術を提供することである。【解決手段】整地装置51の回転駆動力は後車輪12を駆動支持するリヤアクスルケース11より取り出す構造とし、該リヤアクスルケース11内の後車輪12駆動用の最終伝達軸(リヤ車軸14)に対して、動力伝達上手側の中間軸(リヤ中間軸24)より動力を分岐して前記整地装置51に駆動力を伝達する。【選択図】図2
