To provide a combine capable of preventing damage of a waste straw shredding device due to vibration.SOLUTION: A combine comprises: a thresher 9 for performing threshing processing of reaped grain culms； and a waste straw shredding device 12 coupled to a rear part of the thresher 9, and performing shredding processing of the waste straw after being subjected to threshing processing by the thresher 9. The waste straw shredding device 12 comprises: a rotor 21 to which a plurality of rotary blades 20 are attached, and which can rotate around a shaft core X1 extending in a machine body lateral direction； and a case 22 which covers the rotor 21 and rotatably supports the rotor 21 around the shaft core X1. A vibration sensor 39 for detecting vibration of the waste straw shredding device 12 is supported to the case 22.SELECTED DRAWING: Figure 3【課題】振動による排藁細断装置の損傷を防止可能なコンバインが要望されている。【解決手段】刈取穀稈を脱穀処理する脱穀装置９と、脱穀装置９の後部に連設され、脱穀装置９による脱穀処理後の排藁を細断処理する排藁細断装置１２と、が備えられ、排藁細断装置１２は、複数の回転刃２０が取り付けられると共に機体左右方向に延びる軸芯Ｘ１周りで回転可能な回転体２１と、回転体２１を覆うと共に回転体２１を軸芯Ｘ１周りで回転可能に支持するケース２２と、を有し、排藁細断装置１２の振動を検出する振動センサ３９が、ケース２２に支持されている。【選択図】図３
