PROBLEM TO BE SOLVED: To provide an agricultural implement capable of coping with all of working forms in a field.SOLUTION: This trencher 1 which is an example of agricultural implements has a mounting part 10 to be mounted on the rear part of a traveling machine body 90, an offset mechanism part 20 attached to the same and forming a parallel link mechanism capable transferring in left and right directions, and a working part 40 mounted at the rear end side of the same and performing ditching work by being maintained in a prescribed direction. The working part 40 is provided by being mounted at the rear end part of the offset mechanism part as rotatable, progressing accompanying with the advancing and retreating travels of the traveling machine body 90, and performing an advancing work and a retreating work at optional positions from a left hand side offset working position to a right hand side offset working position. The working part 40 has a trenching body which has a rotary shaft equipped with a screw blade body and a jumping-out plate attached on the upper part of the same. The jumping-out plate is covered by a covering part 43, and a discharging direction-changing mechanism enabling the change of the discharging direction of soil is installed at the covering part 43.COPYRIGHT: (C)2007,JPO&INPIT【課題】圃場での作業をあらゆる作業形態で対応可能な農作業機を提供する。【解決手段】農作業機の一例である溝掘機1は、走行機体90の後部に装着される装着部10と、これに取り付けられて左右方向に移動可能な平行リンク機構をなすオフセット機構部20と、この後端側に取り付けられて所定方向に維持されて溝掘作業を行う作業部40を有する。作業部40はオフセット機構部の後端部に回動可能に取り付けられ、走行機体90の前進走行並びに後進走行に伴って進行して、左側オフセット作業位置から右側オフセット作業位置までの任意の位置において前進作業並びに後進作業を行う。作業部40は、溝掘り体を有し、これは螺旋刃体を備えた回転軸と、この上部に取り付けられた跳ね出し板を有する。跳ね出し板はカバー部43によって覆われ、カバー部43には土壌の排出方向を変更可能にする排出方向変更機構が設けられる。【選択図】図1
