PROBLEM TO BE SOLVED: To provide a harvester in which crops are not conveyed to a storage tank by a conveying part when the storage tank is not in a storage state.SOLUTION: A harvester includes: a harvesting part for harvesting crops in a farm field a storage tank 8 for storing the crops harvested by the harvesting part a feeder for conveying the harvested crops from the harvesting part to the storage tank 8 a clutch 28 that is switched between a transmission state in which power is transmitted to the feeder, and a cut-off state in which power is not transmitted to the feeder a tank cylinder 13 for performing a state change operation for the storage tank 8 between a storage state in which the crops can be stored, and a discharge state in which the stored crops can be discharged a tank sensor 16 that can detect the storage state of the storage tank 8 and a clutch restraining part 20 for restraining the switching of the clutch 28 to the transmission state when the tank sensor 16 does not detect the storage state.COPYRIGHT: (C)2015,JPO&INPIT【課題】貯留タンクが貯留状態でない場合に、搬送部によって作物が貯留タンクに搬送されることがない収穫機が要望されている。【解決手段】圃場の作物を収穫する収穫部と、前記収穫部によって収穫された収穫物を貯留する貯留タンク8と、前記収穫物を前記収穫部から貯留タンク8に搬送するフィーダと、前記フィーダに動力を伝達する伝達状態と前記フィーダに動力を伝達しない遮断状態とに切り替わるクラッチ28と、貯留タンク8を、作物を貯留可能な貯留状態と貯留された作物を排出可能な排出状態との間で状態変更操作するタンクシリンダ13と、貯留タンク8が貯留状態であるのを検知可能なタンクセンサ16と、タンクセンサ16が貯留状態を検知していない場合に、クラッチ28が伝達状態に切り替わるのを牽制するクラッチ牽制部20と、が備えられている。【選択図】図7
