PROBLEM TO BE SOLVED: To solve a problem that in a conventional multi-row agricultural implement in which two or more seeders, fertilizing apparatuses or the like are parallelly disposed, a seeder is made to rock following unevenness of a field surface for respective rows, a driving mechanism by a compacting roller or the like is disposed for respective seeders, and a driving speed of a seeder may change for respective seeders with a slip or the like of the compacting roller, thereby sowing accuracy falls off, and yield and quality of crops in the whole field deteriorate.SOLUTION: A single driving shaft 35 which transmits power to a seeder 8 is disposed, a first boss member 60 which pivotally supports the driving shaft 35, and a second boss member 62 which pivotally supports an input shaft 48 to a seeder 8 are connected together through a flexible link mechanism 53 which can be flexible in response to swinging of the seeder 8, the flexible link mechanism 53 is configured to continuously dispose two or more transmission cases 63, 64, and a power transmission route 55 from the driving shaft 35 to the input shaft 48 is disposed along the transmission cases 63, 64.COPYRIGHT: (C)2012,JPO&INPIT【課題】従来より、複数の播種装置・施肥装置等を並設した多条農用作業機では、各条毎に圃場面の凹凸に追従して播種装置を揺動させていたため、各播種装置毎に鎮圧ローラ等による駆動機構が設けられていた。このため、該鎮圧ローラのスリップ等によって各播種装置毎に播種装置の駆動速度が異なる場合があり、播種精度が低下し、圃場全体における作物の収量・品質が悪化する、という問題があった。【解決手段】播種装置8に動力を伝達する単一の駆動軸35を設け、該駆動軸35を軸支する第一ボス部材60と、播種装置8への入力軸48を軸支する第二ボス部材62とは、播種装置8の揺動に応じて伸縮可能な伸縮リンク機構53を介して連結すると共に、該伸縮リンク機構53は、複数の伝動ケース63・64を連設して構成し、該伝動ケース63・64に沿って駆動軸35から入力軸48までの動力伝達経路55を設けた。【選択図】 図7
