PROBLEM TO BE SOLVED: To appropriately operate each discharge mechanism in a harvester having two types of discharging mechanisms for discharging threshed grains.SOLUTION: A harvester includes a threshed grain discharge device having a first discharge port which discharges threshed grains when the threshed grain tank is in an ascending posture, a lateral transportation unit connected to an upper end of a longitudinal transportation unit, and a second discharge port arranged at the lateral transportation unit a turning mechanism which turns the threshed grain discharge device about a longitudinal device between a housed posture where the lateral transportation unit is positioned above the threshed grain tank, and a discharge posture where the lateral transportation unit is projected lateral outside of the machine body a discharge mode selection unit for selecting a first discharge mode for discharging the threshed grains from the first discharge port, or a second discharge mode for discharging the threshed grains from the second discharge port and a threshed grain discharge control unit which allows the threshed grain discharge device to turn to the discharge posture according to a threshed grains discharge preparation command when the first discharge mode is selected by the discharge mode selection unit.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2019,JPO&INPIT【課題】脱穀物を排出するための2つのタイプの排出機構を備えた収穫機において、各排出機構を適切に動作させること。【解決手段】収穫機は、脱穀物タンクが上昇姿勢となったときに脱穀物を排出する第1排出口と、縦搬送部の上端部に連結された横搬送部と横搬送部に設けられた第2排出口を有する脱穀物排出装置と、横搬送部が脱穀物タンクの上方に位置する格納姿勢と、横搬送部が機体横外に張り出す排出姿勢との間で脱穀物排出装置を縦軸心周りで旋回させる旋回機構と、脱穀物を第1排出口から排出する第1排出モードと、脱穀物を第2排出口から排出する第2排出モードとを選択する排出モード選択部と、排出モード選択部によって第1排出モードが選択されているときに脱穀物排出準備指令に応答して、脱穀物排出装置を排出姿勢に旋回させる脱穀物排出制御部を備えている。【選択図】図6
