として、手抜き作業形態への切替えに多大な操作を要し
面倒であった。With this type of combine harvester, when the machine is moved to the headland with the reaping part raised above the ground and the headland is handled manually,
It is necessary to lower the reaping section to a set height position to secure a wide space between the reaping section and the threshing section for supplying the culm, and in parallel with the lowering operation of the reaping section,
It is necessary to engage the clutch for the threshing section and disengage the clutch for the reaping section and the clutch for the traveling device, and as a whole, it is troublesome because a large amount of operations are required to switch to the shortcut work mode.

本考案は、上述のような手扱ぎ作業形態への切替え操作

。In other words, when the machine is moved to the headland with the reaping section raised above the ground and the headland can be handled manually, the clutch for the threshing section is engaged, the clutch for the reaping section and the clutch for the traveling device are disengaged. This is naturally necessary for manual handling work such as manual handling work, and by simply operating the latch, the reaping part can be automatically lowered to a set height position suitable for manual handling work. There is no need for any special operation to perform this operation, and the switching operation to the manual work mode can be performed simply and easily with as few steps as possible.

また、前記刈取部の設定高さ位置がこの刈取部駆動昇降
