PROBLEM TO BE SOLVED: To provide a rice transplanter that simply performs attaching and detaching operation of a land-leveling rotor drive shaft for taking out power to a land-leveling rotor side and improves assembly workability of the land-leveling rotor drive shaft.SOLUTION: The rice transplanter has a constitution that a rear axle case 33 is equipped with a rear wheel travel input shaft 75 for transmitting power from an engine 21 and the land-leveling rotor drive shaft 85 for branching power of the rear wheel travel input shaft 75 and transmitting the power to a land-leveling rotor 80. A backward shaft hole 33b to which the land-leveling rotor drive shaft 85 is inserted is formed in the rear axle case 33. The land-leveling rotor drive shaft 85 is drawn out from the backward shaft hole 33b opened toward the rear side of the rear axle case 33 to the rear side of the rear axle case 33.COPYRIGHT: (C)2010,JPO&INPIT【課題】整地ロータ側に動力を取出す整地ロータ駆動軸の着脱作業を簡単に実行でき、整地ロータ駆動軸の組付け作業性を向上できるようにした田植機を提供する。【解決手段】リヤアクスルケース33に、エンジン21からの動力を伝達する後輪走行入力軸75と、後輪走行入力軸75の動力を分岐して整地ロータ80に伝達する整地ロータ駆動軸85を設ける構造であって、整地ロータ駆動軸85を内挿させる後向き軸孔33bがリヤアクスルケース33に形成され、リヤアクスルケース33の後面側に向けて開口された後向き軸孔33bから、リヤアクスルケース33の後側方に整地ロータ駆動軸85を抜出し可能に構成した。【選択図】図8
