PROBLEM TO BE SOLVED: To provide a combine harvester which can surely perform the IN-operation of a reaping clutch on the start of a harvesting work and also enables the IN-operation of only a threshing clutch, if necessary.SOLUTION: A working clutch lever 45 is formed in a state capable of being freely operated into a clutch-off position OFF, a threshing work position M or a harvesting work position ON, and has a threshing position sensor 64 and a harvesting position sensor 65 for detecting the operations. Clutch control means 87 for controlling a threshing clutch Ce and a reaping clutch Cd from the detection results of the sensors is disposed. The clutch control means 87 sets the threshing clutch Ce and the reaping clutch Cd to clutch-in states at the harvesting work position ON without setting the threshing clutch Ce to a clutch-in state, when the working clutch lever 45 is operated from the clutch-off position OFF to the harvesting work position ON, and passes through the threshing work position M without setting the threshing clutch Ce to a clutch-in state, when the working clutch lever is operated from the clutch-off position OFF to the harvesting work position ON and passes through the threshing work position M.COPYRIGHT: (C)2011,JPO&INPIT【課題】収穫作業の開始時には刈取クラッチの入り操作を確実に行い、必要に応じて脱穀クラッチのみの入り操作も可能なコンバインを構成する。【解決手段】作業クラッチレバー45が、切り位置OFFと、脱穀作業位置Mと、収穫作業位置ONとに操作自在に構成され、この操作を検出する脱穀位置センサ64と収穫位置センサ65とを備えている。これらのセンサの検出結果から脱穀クラッチCeと刈取クラッチCdとを制御するクラッチ制御手段87を備えている。クラッチ制御手段87は、作業クラッチレバー45を切り位置OFFから収穫作業位置ONに操作する際に、脱穀作業位置Mを通過する際に脱穀クラッチCeを入り状態に設定せず、収穫作業位置ONにおいて脱穀クラッチCeと刈取クラッチCdとを入り状態に設定する。【選択図】図11
