PROBLEM TO BE SOLVED: To provide a working implement transmission of a rice transplanter capable of contributing to the control of the posture of planted seedlings.SOLUTION: In a working implement transmission of a rice transplanter, intrarow spacing transmission switching mechanism (intrarow spacing transmission) having an idle shaft (132) is provided. The rotation of a planting output shaft (134) is allowed to switch a uniform speed/non-uniform speed by the intrarow spacing transmission switching mechanism. Upon parse planting, the driving force of an input shaft (131) drives the planting output shaft (134) to set the rotation of a planting drive to a non-uniform speed.COPYRIGHT: (C)2014,JPO&INPIT【課題】植付けた苗の姿勢の統制に寄与し得る田植機の作業機変速装置を提供する。【解決手段】田植機の作業機変速装置において、アイドル軸(132)を備える株間変速切替機構(株間変速)を設け、この株間変速切替機構により植付出力軸(134)の回転を等速/不等速に切り替え可能とし、疎植時には、入力軸(131)の駆動力が植付出力軸(134)を駆動させて植付駆動の回転を不等速にした。【選択図】図6
