PROBLEM TO BE SOLVED: To provide a reaping and lifting or lowering controller of a reaping harvester, which can control the operation of a lifting or lowering operation means in a proper control state in response to the skill level of a worker, the difference of a working state, and the like.SOLUTION: In the reaping and lifting or lowering controller of the reaping harvester, a control means H for controlling the operation of a lifting or lowering operation means for lifting or lowering a reaping portion has an automatic lifting or lowering control mode for controlling the operation of the lifting or lowering operation means C1 in a form for executing a lifting treatment for lifting the reaping portion and a lowering treatment for lowering the reaping portion, and an automatic lifting control mode for controlling the operation of the lifting or lowering operation means C1 in a form for executing the lifting treatment only among the lifting treatment and the lowering treatment, as a control mode for executing an automatic control treatment. Also, the control means H can freely switch into a state for executing the automatic control treatment in the automatic lifting or lowering control mode or into a state for executing the automatic control treatment in the automatic lifting control mode, on the basis of the switching command of a manual operation type mode switching command means.COPYRIGHT: (C)2010,JPO&INPIT【課題】作業者の熟練度や作業状況の違い等に応じて適切な制御状態で昇降操作手段の作動を制御することが可能となる刈取収穫機の刈取昇降制御装置を提供する。【解決手段】刈取部を昇降する昇降操作手段の作動を制御する制御手段Hが、自動制御処理を実行する制御モードとして、刈取部を上昇させる上昇処理及び刈取部を下降させる下降処理の夫々を実行する形態で昇降操作手段C1の作動を制御する自動昇降制御モードと、前記上昇処理及び前記下降処理のうちの前記上昇処理のみを実行する形態で昇降操作手段C1の作動を制御する自動上昇制御モードとを備えるように構成され、且つ、手動操作式のモード切換指令手段の切り換え指令に基づいて、前記自動昇降制御モードにて前記自動制御処理を実行する状態と、前記自動上昇制御モードにて前記自動制御処理を実行する状態とに切り換え自在に構成されている。【選択図】図5
