PROBLEM TO BE SOLVED: To provide a combine-harvester that prevents a tip of a reaping and transporting part from being plunged into a field and damaged when automatically lifting and lowering the reaping and transporting part, and also when performed manually.SOLUTION: A combine-harvester includes: a left/right tilt control for constantly maintaining a left and right tilt state of a traveling undercarriage (1) and a controller (21) capable of executing a reaping height control for constantly maintaining a ground height of the reaping and transporting part (7). The controller (21): performs the left/right tilt control while aiming at a state where a traveling undercarriage (1) is parallel to the ground in a fully automatic reaping control mode of executing both of the left/right tilt control and the reaping height control and performs the left/right tilt control while aiming at a state where the traveling undercarriage (1) is right downward to the ground in a manual reaping lift control state by executing only right-left level control and manually controlling the lifting of the reaping and transporting part (7).COPYRIGHT: (C)2015,JPO&INPIT【課題】本発明は、刈取搬送部の昇降を自動で行う際だけで無く、手動で行う場合にも刈取搬送部の先端が圃場に突っ込んで破損することが無いようにすることを課題とする。【解決手段】走行車台(1)の左右の傾斜状態を一定に維持する左右傾斜制御と刈取搬送部(7)の地上高を一定に維持する刈高さ制御を実行可能なコントローラ(21)を備えたコンバインにおいて、コントローラ(21)は、左右傾斜制御と刈高さ制御の双方を実行する全自動刈取制御モードにおいて、走行車台(1)が地面に対して平行な状態を目標として左右傾斜制御を行い、左右水平制御のみを実行して手動で刈取搬送部(7)を昇降制御する手動刈取昇降制御状態においては、走行車台(1)の地面に対して右下がりの状態を目標として左右傾斜制御を実行する。【選択図】図4
