PROBLEM TO BE SOLVED: To provide a walking type cultivator with a parking brake which improves the stabilization and handleability of tillage operation by the cooperation of a deadman lever type clutch and a parking brake, and enables efficient and stable tillage operation by securing wide responsiveness depending on conditions.SOLUTION: A brake device (9) for parking includes a brake member (13) making a braking force act on an output shaft (3a) of a clutch device (8), an over-fulcrum spring (14) for holding the brake member (13) to a braking position and a not-braking position, respectively, and a retracting member (15) integral with the brake member (13) to retract the brake member from the braking position according to received action. The movable range of the clutch member (12) is provided in a position where the clutch member (12) at a transmission position acts on the retracting member (15) of the brake member (13) at a braking position within a range where the brake member is held at the side of the braking position, whereby braking can be controlled in conjunction with the operation of a clutch lever (8a).COPYRIGHT: (C)2013,JPO&INPIT【課題】デッドマンレバー式のクラッチと駐車ブレーキの連係によって耕耘作業の安定化と操作性の改善を図るとともに、状況に合わせた幅広い対応性の確保によって効率のよい安定した耕耘作業を可能とする駐車ブレーキ付き歩行型耕耘機を提供する。【解決手段】駐車用の制動装置(9)は、クラッチ装置(8)の出力軸(3a)に制動力を作用するブレーキ部材(13)と、このブレーキ部材(13)をその制動位置と非制動位置のそれぞれに保持する支点越えバネ(14)と、受けた作用に応じて上記ブレーキ部材(13)を制動位置から待避させる一体構成の待避部材(15)とを備え、伝動位置のクラッチ部材(12)が制動位置にあるブレーキ部材(13)の待避部材(15)に上記制動位置側の保持範囲内で作用する位置に上記クラッチ部材(12)の可動範囲を設けることにより、クラッチレバー(8a)の操作と連動してブレーキ調節可能に構成したものである。【選択図】図2
