PROBLEM TO BE SOLVED: To provide a combine harvester having an image display monitor with an excellent operability, thereby to improve a working property.SOLUTION: A combine harvester comprises: an image display monitor M mounted on a drive area O and capable of splitting and displaying a plurality of images in one image plane a forward camera C1 disposed at the front portion of a machine body for photographing the forward image of the machine body a grain discharge auger camera C2 disposed in the upper portion of the machine body for photographing an image of the leading end portion of a grain discharge auger 13 and a backward camera C3 disposed at the back of the machine body for photographing the backward image of the machine body. The image display monitor M includes an image changeover mechanism S for displaying images taken for a work object containing the forward image of the machine body by the forward camera C1 the image of the leading end portion of the grain discharge auger 13 by the grain discharge auger camera C2 and the backward image of the machine body by the backward camera C3, and capable of changing into one image displaying the work in accordance with the object of the work. This image changeover mechanism S is equipped with a preference mechanism P for controlling the changeover of the object image in accordance with the work situation.COPYRIGHT: (C)2014,JPO&INPIT【課題】操作性に優れた画像表示モニタを備え、作業性を向上させたコンバインを提供する。【解決手段】操縦部Oに設けた、複数の画像を1画面に分割表示可能な画像表示モニタMと、機体の前部に設けた、機体前方の画像を撮影する前方カメラC1と、機体の上部に設けた、穀粒排出オーガ13の先端部の画像を撮影する穀粒排出オーガカメラC2と、機体の後部に設けた、機体後方の画像を撮影する後方カメラC3とを備え、画像表示モニタMには、前方カメラC1による機体前方の画像と、穀粒排出オーガカメラC2による穀粒排出オーガ13の先端部の画像と、後方カメラC3による機体後方の画像とを含む作業対象を撮影した画像を表示し、作業対象に応じて当該作業を表示する1画像に切換可能な画像切換機構Sを備え、この画像切換機構Sは、作業状況に応じて対象画像の切換を制御する優先機構Pを設けた。【選択図】図6
