PROBLEM TO BE SOLVED: To provide a combine preventing a reaping device from lowering even with abnormality occurring to a control device and enhancing safety in a case where a worker enters under the reaping device to perform maintenance by lifting the reaping device.SOLUTION: A combine restricts lowering of a reaping device 3 by controlling a reaping lifting/lowering cylinder 8 via a reaping control device 29 linked to a main control device 25 based on operation of a reaping lock switch 25f connected to the main control device 25. The main control device 25, the reaping control device 29, and other plural control devices 26, 27, 28 are linked with communication means C1-C10. A communication state of the communication means C1-C10 is monitored and an emergency lifting control output lifting the reaping device 3 is executed from the reaping control device 29 to the reaping lifting/lowering cylinder 8 side when communication abnormality is detected.SELECTED DRAWING: Figure 4 【課題】コンバインにおいて、刈取装置を上昇させ、作業者が刈取装置の下に潜り込んでメンテナンスを行う場合に、制御装置に異常が発生しても刈取装置が下降することを防ぎ、安全性を高める。【解決手段】メイン制御装置（２５）に接続された刈取ロックスイッチ（２５ｆ）の操作に基づいて、前記メイン制御装置（２５）に連携された刈取制御装置（２９）を介して刈取昇降シリンダ（８）を制御し、刈取装置（３）の下降を牽制するコンバインにおいて、前記メイン制御装置（２５）と前記刈取制御装置（２９）と他の複数の制御装置（２６、２７、２８）を通信手段（Ｃ１〜Ｃ１０）で連携し、該通信手段（Ｃ１〜Ｃ１０）の通信状態を監視し、通信異常が検出されると前記刈取制御装置（２９）から刈取昇降シリンダ（８）側に前記刈取装置（３）を上昇させる緊急上昇制御用の出力がなされる構成とする。【選択図】図４
