PROBLEM TO BE SOLVED: To provide a combine capable of conveying and reaping grain culms appropriately, which has a structure capable of securing safety.SOLUTION: A combine includes, in a reaping pretreatment apparatus (3) for reaping grain culms and conveying them: a conveying device (10) for conveying the grain culms a reaping device (80) having a cutting blade device (20) for cutting the grain culms a reaping table (30) having an auger (32) for gathering the reaped grain culms and a feeder house (40) for conveying the grain culms to a thresher (4). A rear part of the reaping device (80) is supported vertically and rotationally on a front part of the reaping table (30). The combine includes a ground contact type height sensor (70) for detecting a height from the ground of the reaping device (80), and a control device (100) for executing control to lift and lower the reaping pretreatment apparatus (3) based on the height from the ground detected by the height sensor (70). When it is detected by the height sensor (70) that the height from the ground of the reaping device (80) has become a predetermined height or lower, driving of the conveyance device (10) is started.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2019,JPO&INPIT【課題】穀稈を適切に搬送して刈取ることができ、かつ、安全性を確保できる構造を備えるコンバインを提供する。【解決手段】穀稈を刈取って搬送する刈取前処理装置(3)に、穀稈を搬送する搬送装置(10)と穀稈を切断する刈刃装置(20)を有する刈取装置(80)と刈取られた穀稈を寄せ集めるオーガ(32)を有する刈取テーブル(30)と、穀稈を脱穀装置(4)に搬送するフィーダハウス(40)を備え、刈取装置(80)の後部を刈取テーブル(30)の前部に上下回動可能に支持したコンバインにおいて、刈取装置(80)の対地高さを検出する接地式の高さセンサ(70)と、この高さセンサ(70)で検出される対地高さに基づいて刈取前処理装置(3)を昇降制御する制御装置(100)を備え、高さセンサ(70)により、刈取装置(80)の対地高さが所定高さ以下になったことが検出された場合に、搬送装置(10)の駆動が開始される構成とする。【選択図】図7
