PROBLEM TO BE SOLVED: To provide a combine in which an actual loss amount corresponds to a detection value of a loss sensor.SOLUTION: A grain amount determined from a detection value of a loss sensor 34 is corrected according to the setting of a chaff sieve 18 or a winnower 27, and a loss amount is calculated accurately by correlating an actual loss amount with the detection value of the loss sensor 34, to thereby control properly operation of the chaff sieve 18 or the winnower 27. A function showing a relation between the loss amount and the detection value of the loss sensor 34 is set according to the magnitude of an angle of the chaff sieve 18 or a rotational frequency of the winnower 27.COPYRIGHT: (C)2014,JPO&INPIT【課題】実際のロス量とロスセンサの検出値とが対応するコンバインを提供する。【解決手段】チャフシーブ18又は唐箕27の設定に応じて、ロスセンサ34の検出値から求まる穀粒量を補正し、実際のロス量とロスセンサ34の検出値とを対応させて、精度良くロス量を演算し、チャフシーブ18又は唐箕27の動作を適切に制御する。チャフシーブ18の角度又は唐箕27の回転数の大小に応じて、ロス量及びロスセンサ34の検出値の関係を示す関数を設定する。【選択図】図2
