PROBLEM TO BE SOLVED: To provide a combine in which a deposition state of soil in a cutting blade and waste straws can simply be grasped and the accuracy of removing deposits is improved.SOLUTION: A combine is provided with a control unit (40) including: a cutting blade device (15) with an upper blade (25) and a lower blade (23), and reaping grain culm in a field a deposit detection sensor (37) for detecting deposits deposited on the cutting blade device (15) and working state determination means for determining whether or not being in the reaping threshing work. When determined to be in the reaping threshing work by the working state determination means, a control signal is configured to be output from the control unit (40) based on detection information by the deposit detection sensor (37). Also, the control unit (40) is configured such that a warning signal is output based on the deposit detection information by the deposit detection sensor (37), or a signal for changing the cutting blade device (15) from a working posture (a) to a non-working posture (b) is output.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2018,JPO&INPIT【課題】刈刃上の土や藁屑等の堆積状況の把握の容易化と堆積物の除去の精度向上。【解決手段】 上刃(25)と下刃(23)を備え圃場の穀稈を刈り取る刈刃装置(15)と、該刈刃装置(15)上に堆積する堆積物を検知する堆積物検知センサ(37)と、刈取脱穀作業中であるか否かを判定する作業状態判定手段を備えた制御部(40)を設け、前記作業状態判定手段によって刈取脱穀作業中であると判定された場合に、前記堆積物検知センサ(37)による検知情報に基づいて前記制御部(40)から制御信号が出力される構成とした。また、制御部(40)は、前記堆積物検知センサ(37)による堆積物検知情報に基づいて、警報信号が出力され、あるいは、刈刃装置(15)を作業姿勢(イ)から非作業姿勢(ロ)へ変更する信号が出力される。【選択図】 図6
