定時間後に復帰すべく制御したことを特徴とする
コンバインの刈取・車速制御機構。 A continuously variable transmission device A capable of changing speed by a control means is provided at the input section of the reaping drive, and a grain culm sensor 41 is provided at an arbitrary position where the grain culm passes through the reaping section to detect the grain culm and send the grain to the reaping section. A reaping/vehicle speed control mechanism for a combine harvester, characterized in that the continuously variable transmission device A is controlled to be shifted to the deceleration side immediately after detecting that the culm has disappeared, and to return after a certain period of time.
