PROBLEM TO BE SOLVED: To provide an agricultural implement capable of carrying out advancing operation along the side of a field, and capable of carrying out the advancing operation from an edge to another edge of the field.SOLUTION: A groove-digging machine 1 which is an example of the agricultural implement, has an attaching part to be attached to the rear part of a traveling machine body, an offset mechanism attached thereto and forming a parallel link mechanism movable in the right and left direction, and an operation part 50 attached to the rear end side of the offset mechanism and carrying out a groove-digging operation by being maintained in a prescribed direction. The operation part 50 has a groove-digging body 60 attached so as to be freely rotatable to a flange 51 attached to a supporting shaft 25 extended downward from the rear end of the offset mechanism, and the groove-digging body 60 has a rotary shaft 61 having a helical blade 62, and a throwing-out plate 63 attached to the upper part of the rotary shaft 61. The throwing-out plate 63 is covered with a cover 53, and a discharging direction-changing mechanism 66 enabling the discharging direction of dug soil to be changed, is installed in the cover part 53.COPYRIGHT: (C)2011,JPO&INPIT【課題】圃場の辺に沿って前進作業ができ、圃場の端から端まで直進作業が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、走行機体の後部に装着される装着部と、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り作業を行う作業部50を有する。作業部50は、オフセット機構部の後端部から下方へ延びる支持軸25に取り付けられたフランジ部51に回転自在に取り付けられた溝掘り体60を有し、溝掘り体60は螺旋刃体62を備えた回転軸61と、この上部に取り付けられた跳ね出し板63を有する。跳ね出し板63はカバー部53によって覆われ、カバー部53には掘削された土壌の排出方向を変更可能にする排出方向変更機構66が設けられている。【選択図】図2
