PROBLEM TO BE SOLVED: To provide a combine capable of grasping an overall predicted yield of an entire field. SOLUTION: A threshing unit 6 for threshing a harvested grain, a grain tank 8 for storing the threshed grains, a grain detection unit 39 for detecting the stored amount of the grain tank 8, and running in a field. The machine body position detection sensor 52 that measures the position of the machine body 3 and the field area of the already cut land that has already been cut and the uncut land that has not been cut at the stage when the outer circumference cutting work of the field is completed are calculated. , The control unit 51 that calculates the overall predicted yield of the entire field based on the yield of the harvested land measured by the grain detection unit 39, and the control unit 51 that calculates the overall predicted yield of the entire field. The display device 65 and the like are provided. [Selection diagram] Fig. 6【課題】圃場全体の全体予測収穫量を把握可能なコンバインを提供すること。【解決手段】刈取られた穀稈を脱穀する脱穀部６と、脱穀された穀粒を貯留するグレンタンク８と、グレンタンク８の貯留量を検出する穀粒検出ユニット３９と、圃場内における走行機体３の位置を測定する機体位置検出センサ５２と、圃場の外周刈取り作業が終了した段階における既に刈取り作業を終えた既刈り地と刈取り作業を終えていない未刈り地との圃場面積を算出し、穀粒検出ユニット３９で計測された既刈り地の収穫量に基づいて圃場全体の全体予測収穫量を算出する制御部５１と、制御部５１で算出された圃場全体の全体予測収穫量を表示する表示装置６５と、を備えた。【選択図】図６
