PROBLEM TO BE SOLVED: To provide farm implement which can improve clod-breaking property.SOLUTION: This farm implement 1 includes a central working portion 2 and extended work portions 3 turnable with respect to central working portion 2. A tilling body 7 of the central working portion 2 has a rotation shaft 21, tilling tines 23 attached to the rotation shaft 21, and one side engaging members 22. An extended tilling body 32 of each extended work portion 3 has a rotation shaft 41, tilling tines 43 attached to the rotation shaft 41, and other side engaging members 42. Each of extended machine frames 31 has a bearing plate 39 projected from an inside plate 35 onto an outside plate 36 side, supporting the axial direction end of the rotation shaft 41, and covering the outer peripheral side of the other side engaging members 42. The tip portion 43a of the tilling tine 43 closest to the bearing plate 39 is moved on the outer peripheral side position of the bearing plate 39.COPYRIGHT: (C)2010,JPO&INPIT【課題】砕土性の向上を図ることができる農作業機を提供する。【解決手段】農作業機1は、中央作業部2と、この中央作業部2に対して回動する延長作業部3とを備える。中央作業部2の耕耘体7は、回転軸21と、回転軸21に取り付けた耕耘爪23および一方側係合体22とを有する。延長作業部3の延長耕耘体32は、回転軸41と、この回転軸41に取り付けた耕耘爪43および他方側係合体42とを有する。延長機体31は、内側板35から外側板36側に突出し回転軸41の軸方向端部を支持し他方側係合体42の外周側を覆う軸受板39を有する。軸受板39に最も近い耕耘爪43の先端部43aが軸受板39の外周側位置を移動する。【選択図】図1
