PROBLEM TO BE SOLVED: To provide a farm working machine which has a working implement and an auxiliary working implement and in which the operations of a working clutch and an auxiliary working clutch into transmission states can suitably automatically be performed.SOLUTION: This farm working machine has a setting means for setting a timing when the working clutch 26 should be operated into the transmission state from the disengagement states of the working clutch 26 and the auxiliary working clutch 27 after the transmission. An auxiliary working clutch operation means 56 is provided for operating the auxiliary working clutch 27 into the transmission state, when reaching a timing earlier by a prescribed time than the timing by the setting means. Further, a working clutch operation means 54 is provided for operating the working clutch 26 into the transmission state, when reaching the timing by the setting means.COPYRIGHT: (C)2009,JPO&INPIT【課題】 農作業機において、作業装置及び補助作業装置を備えた場合、作業及び補助作業クラッチの伝動状態への操作が、適切に自動的に行われるように構成する。【解決手段】 作業及び補助作業クラッチ26,27の遮断状態から、どれだけの後に作業クラッチ26を伝動状態に操作すべきかのタイミングを設定する設定手段を備える。設定手段によるタイミングよりも所定量だけ手前のタイミングに達すると、補助作業クラッチ27を伝動状態に操作する補助作業クラッチ操作手段56を備える。設定手段によるタイミングに達すると、作業クラッチ26を伝動状態に操作する作業クラッチ操作手段54を備える。【選択図】 図3
