PROBLEM TO BE SOLVED: To provide a furrower that makes it possible to easily switch between a tilling operation and a furrowing operation by making collapsible a furrowing element used for furrowing.SOLUTION: The furrower is provided at the rear of a rotary tiller K having a tilling unit R and is used for a furrowing operation as the earth tilled by the tilling unit R is pushed away by the furrowing element 7. A rectangular leveling plate 3 is swingably attached via hinges 6 to a rear end edge section 2a of a rotary cover 2 covering approximately an upper half of the tilling unit R. A collapsible fixing means for enabling the furrowing element 7 comprising a plurality of ridging plates to collapse via hinges 8 into an inner surface 3c of the leveling plate 3 in such a manner as to overlap, and for fixing each of the ridging plates to the leveling plate 3 in an overlapping manner, is provided on the inner surface 3c of the leveling plate 3. An upright fixing means by which the ridging plates each having a certain shape matching the shape of a ridge to be made can be fixed in a certain position while being roughly upright is provided on the inner surface 3c of the leveling plate. A supporting and fixing unit 5 capable of fixing the leveling plate 3 in an approximately horizontal state is provided between a resisting bar 4 and an outer surface 3d of the leveling plate.COPYRIGHT: (C)2012,JPO&INPIT【課題】畝立てを行う畝立て体を折り畳み式とすることで容易に耕耘作業と畝立て作業の容易な転換を可能とした畝立て装置を提供する。【解決手段】耕耘部Rを備えたロータリ耕耘機Kの後部に設けられ、耕耘部Rで耕耘された土を畝立て体7で押し分けて畝立て作業を行う畝立て装置であって、耕耘部Rの略上半分を覆うロータリカバー2の後端縁部2aにヒンジ6を介して擺動可能に矩形状の整地板3を取り付け、整地板3の内面3cに複数の培土板から成る畝立て体7をヒンジ8を介して整地板の内面3c内に折り重なるように折り畳み可能とするとともに各培土板を整地板3に折り畳み状態で固定する折畳固定手段を設け、整地板の内面3cに畝立てする畝の形状に応じた任意の形状の培土板を任意の位置に略直立して固定可能とする直立固定手段を設ける。整地板3を略水平状態で固定可能な支持固定部5を抵抗棒4と前記整地板の外面3dとの間に設ける。【選択図】 図1
