チおよびブレーキを切換える油圧装置の操向バル
ブ６２を操作レバーで切換え操作するようにした
コンバインにおいて、前記操向バルブ６２のスプ
ールの外周端部に作動油を一部リークさせる定圧
部設けて油圧をサイドクラツチ切り圧まで昇圧し
た後一定圧を保持し、それに続くブレーキ作動過
程で更に昇圧させるように構成したことを特徴と
するコンバインにおける操向装置。 In a combine harvester in which a steering valve 62 of a hydraulic device for switching side clutches and brakes attached to a pair of left and right crawlers is switched and operated by an operating lever, a portion of hydraulic oil is applied to the outer peripheral end of the spool of the steering valve 62. A steering device for a combine harvester, characterized in that a constant pressure part is provided for leakage, the hydraulic pressure is increased to a side clutch disengagement pressure, a constant pressure is maintained, and the pressure is further increased during the subsequent brake operation process.
