To solve the problem in which: conventionally manual threshing operation needs individual operations of a throttle lever； and there is a problem in operability.SOLUTION: A combine-harvester comprises: a throttle lever 13 at an operation part 6 in which engine speed is raised by tilt operation thereof from an operation end side； a pin 17 arranged protruding in a direction orthogonal to a cross direction of a machine body； a reaping/threshing clutch lever 14 which switches between connection of power transmission and disconnection with respect to a reaping device 4 and a thresher 3； and a linkage plate 20 which is arranged extending to a base end part of the throttle lever 13 and being movable in the cross direction of the machine body by the linkage with the tilt operation of the reaping/threshing clutch lever 14, and has a cam surface 24 pushing the pin 17 in accompany with forward movement of the linkage plate； and an auxiliary nipping and pressing rod 31 which is rotatably arranged around a shaft between a nipping position of a base part at the upper direction of a starting end part of a feed chain 30 arranged at the side of a threshing chamber of the thresher 3 and a retreat position thereof retreating from the upper direction of the starting end part of the feed chain in which the throttle lever 13 and the reaping/threshing clutch lever 14 are moved by the linkage with position changeover of the auxiliary nipping and pressing rod.SELECTED DRAWING: Figure 3【課題】従来、手扱ぎ作業では、スロットルレバーを個別に操作する必要があり、操作性に課題がある。【解決手段】操縦部６には操作端部側からの傾倒操作によってエンジン回転速度が上昇するスロットルレバー１３と、機体の前後方向と直交する方向に突出して設けられたピン１７と、刈取装置４および脱穀装置３に対する動力伝達の接続と切断を切り替える刈脱クラッチレバー１４と、スロットルレバー１３の基端部へ向けて延伸するとともに刈脱クラッチレバー１４の傾倒に連動して機体前後方向へ移動可能に設けられ、前方への移動に伴ってピン１７を押すカム面２４を有する連動プレート２０とを備え、脱穀装置３の扱室の側部に設けたフィードチェン３０の始端部上方に位置する挟持位置と、補助挾扼杆３１の回動に連動してスロットルレバー１３と刈脱クラッチレバー１４が回動する構成としたことを特徴とするコンバイン。【選択図】 図３
