PROBLEM TO BE SOLVED: To provide a mowing implement capable of working while offsetting a work part, easily performing posture adjustment or the like of a mowing work part, not requiring skill in work, having a simple structure, and reducing manufacturing costs.SOLUTION: A mowing implement includes: an installation part 2 installed on a tractor an offset mechanism part 6 including a rotation base part on the installation part 2 and being capable of moving in a right/left direction and a mowing work part 5 arranged on a moving end side of the offset mechanism part 6. The installation part 2 and the offset mechanism part 6 are connected so as to rotate vertically. The mowing implement further includes: rotation detection means 8 detecting a vertical rotation amount and connected so as to automatically control a control valve of a tractor 3-point link mechanism, which is operated so as to be lifted/lowered, of the tractor.COPYRIGHT: (C)2016,JPO&INPIT【課題】作業部をオフセットさせての作業が可能で、刈取り作業部の姿勢調整等が容易に行えて作業に熟練を要さない草刈り作業機であり、構造が簡易で生産コストを押さえた草刈り作業機を提供する。【解決手段】トラクタに装着される装着部2と、装着部2に回動基部を設け左右方向に移動可能なオフセット機構部6と、オフセット機構部6移動端側には刈取り作業部5が設けられていて、装着部2とオフセット機構部6は、上下方向回動自在に連結されているとともに、上下方向回動量を検知する回動検知手段8を備え、トラクタの昇降作動されるトラクタ3点リンク機構のコントロールバルブを自動制御させるべく連繋されている草刈り作業機による。【選択図】 図1
