PROBLEM TO BE SOLVED: To configure a combine harvester so as to be capable of handling design change of the vicinity of a motor part while configuring the combine harvester so that an operator can easily operate a threshing clutch and a work clutch to a transmission state and a cut-off state.SOLUTION: A combine harvester has upstream side transmission systems 9, 10 to which power of a motor part 6 is transmitted and from which threshing transmission systems 13, 14, 17, 21 connected to a thresher 3 and work transmission systems 34, 35, 36 connected to a work device 31 branch out. The upstream side transmission system 9 comprises an upstream side clutch 12 the threshing transmission system 14 comprises a threshing clutch 30 and the work transmission system 35 comprises a work clutch 39. The combine harvester comprises an operation device which operates the upstream side clutch 12, the threshing clutch 30, and the work clutch 39 to a transmission state and a cut-off state.COPYRIGHT: (C)2015,JPO&INPIT【課題】コンバインにおいて、運転者が楽に脱穀クラッチ及び作業クラッチを伝動状態及び遮断状態に操作できるように構成しながら、原動部の付近の設計変更に対応できるように構成する。【解決手段】原動部6の動力が伝達される上手側伝動系9,10が、脱穀装置3に接続される脱穀伝動系13,14,17,21と、作業装置31に接続される作業伝動系34,35,36とに分岐される。上手側クラッチ12を上手側伝動系9に備え、脱穀クラッチ30を脱穀伝動系14に備え、作業クラッチ39を作業伝動系35に備える。上手側クラッチ12、脱穀クラッチ30及び作業クラッチ39を伝動状態及び遮断状態に操作する操作装置を備える。【選択図】図4
