PROBLEM TO BE SOLVED: To obtain an operation structure of a parking brake responding to posture change of an operation unit, in a harvester where the posture of the operation unit can freely be changed into a normal posture and a maintenance posture.SOLUTION: A harvester is provided with an operation tool side portion 17 of the brake operation tool 12 side and a brake side portion 19 of the parking brake side in a link mechanism 21 for linking a brake operation tool 12 with a parking brake. When an operation unit is changed in the maintenance posture side, a first member 18 of the operation tool side portion 17 and a second member 19b of the brake side portion 19 are separated from each other. When the brake operation tool 12 is operated to the braking side in a normal posture of the operation unit, the operation tool side portion 17 is connected with the brake side portion 19 by a contact press between the first member 18 and the second member 19b, and whereby the parking brake is operated to the braking side.SELECTED DRAWING: Figure 12COPYRIGHT: (C)2018,JPO&INPIT【課題】運転部が通常姿勢及びメンテナンス姿勢に姿勢変更自在な収穫機において、運転部の姿勢変更に対応した駐車ブレーキの操作構造を得る。【解決手段】ブレーキ操作具12と駐車ブレーキとを連係するリンク機構21に、ブレーキ操作具12側の操作具側部分17と駐車ブレーキ側のブレーキ側部分19とが備えられている。運転部がメンテナンス姿勢側に変更されると、操作具側部分17の第一部材18とブレーキ側部分19の第二部材19bとが分離する。運転部の通常姿勢においてブレーキ操作具12が制動側に操作されると、第一部材18と第二部材19bとの接触押圧によって操作具側部分17とブレーキ側部分19とが連係されて、駐車ブレーキが制動側に操作される。【選択図】図12
