That is, by appropriately switching the switching mechanism during reaping work, when traveling on the road, etc., it is possible to switch the usage mode of the first operating tool and the second operating tool.
By switching to the mode in which the operating tool is used, it is possible to move the reaping section up and down by operating the first operating tool while holding the steering operating lever. When moving, the reaping section may be raised to a higher position than the normal reaping height to prevent it from coming into contact with irregularities in the field, or when entering the next stroke after turning,
This makes it possible to lower the reaping unit to the reaping height accurately and efficiently while turning by operating the steering control lever, and also to lower the reaping unit to the reaping height. If you switch to the mode that uses the second operating tool, you may accidentally make a mistake when operating the steering operating lever for steering.
Even if the first operating tool is accidentally operated, the reaping section can be raised and lowered accurately and safely using the second operating tool without causing problems such as the reaping section being raised or lowered unexpectedly. As a result, it has become possible to raise and lower the mowing in a manner that is suitable for both the time of reaping work and the time outside of reaping work, such as when traveling on the road.
