PROBLEM TO BE SOLVED: To provide a method for harvesting by a combine harvester designed to perform harvesting operation, while preventing thrusting or sinking of a reaping pre-treating unit into a farm field.SOLUTION: Harvesting travel is carried out by bringing a lowering stopper means 8 acting on the reaping pre-treating unit 10 to be effective, and supporting the reaping pre-treating unit 10 at a connecting height floated from the ground surface to the set reaping height and allowing the reaping pre-treating unit 10 to perform the lifting operation with ground contact reaction force.COPYRIGHT: (C)2010,JPO&INPIT【課題】刈取り前処理部の圃場への突っ込みや沈み込みを防止しながら収穫作業できるコンバインによる収穫方法を提供する。【解決手段】刈取り前処理部10に作用する下降ストッパー手段8を効かせ、刈取り前処理部10を地面から設定刈り高さに浮上した連結高さに支持させながら、かつ、刈取り前処理部10が接地反力によって上昇操作されることを許容しながら収穫走行する。【選択図】図3
