PROBLEM TO BE SOLVED: To provide a harvester capable of suppressing an increase in harvest loss. SOLUTION: This is a harvester 1 capable of automatic traveling, and a reel 17 for scraping a planted grain culm while rotationally driving it around a reel axis along a lateral direction of a machine body, and a mowing device 15 for mowing the planted grain culm. An automatic reel control unit that automatically controls the raising and lowering of the reel 17 with respect to the mowing device 15 during automatic traveling, and an automatic mowing device control unit that automatically controls the raising and lowering of the mowing device 15 with respect to the machine body during automatic traveling An automatic control unit is provided, and the automatic control unit performs mowing control in which the reaper 15 is raised and the reel 17 is lowered when the uncut area CA enters the cut area SA. [Selection diagram] Fig. 5【課題】収穫ロスの増大を抑制できる収穫機を提供する。【解決手段】自動走行可能な収穫機１であって、機体左右方向に沿うリール軸芯周りに回転駆動しながら植立穀稈を掻き込むリール１７と、植立穀稈を刈り取る刈取装置１５と、自動走行中に刈取装置１５に対するリール１７の昇降を自動的に制御する自動リール制御部、及び、自動走行中に機体に対する刈取装置１５の昇降を自動的に制御する自動刈取装置制御部を有する自動制御部と、を備え、自動制御部は、未刈領域ＣＡから既刈領域ＳＡへの進入時に、刈取装置１５を上昇させると共にリール１７を下降させる刈抜け時制御を実行する。【選択図】図５
