ることができる利点を有する。The clutch operating device in this type of reaper only operates to raise the reaping section to the height required for the turn when the machine turns at the end of the field. Since the power transmission clutch for the working device can be automatically disengaged, there is no need to disengage the clutch one by one each time the aircraft turns, which has the advantage of making the aircraft turning operation quick and easy.

る。On the other hand, for example, when reaping in wet fields or highly humid fields, the reaping section may be raised by the amount of settling of the machine to maintain it at the desired cutting height, or when reaping at the edge of a ridge, the reaping section may be raised along the ridge. Position it at a height where it won't collide with other objects! When you want to raise the reaping section to perform work, the clutch is actuated and disconnected dynamically in response to the raising of the reaping section, making it impossible to perform the intended reaping work. There is an inconvenience that cannot be avoided.

い得るに至った。That is, according to the present invention, during normal reaping work, in response to the raising and lowering of the reaping section, the power transmission clutch for the working device of the reaping section is automatically engaged, and the turning operation of the machine at the end of the field is performed. Although it can be done quickly and easily, it is also possible to release the linkage between the raising and lowering operation of the reaping section by the linkage mechanism and the power transmission clutch, and to engage the clutch while the reaping section is raised. Because it is equipped with an operating device that enables operation, the reaping part is raised higher than the normal ground height position, such as in reaping work in wet fields, highly wet fields, and ridge reaping work, so-called high reaping. When performing this, the clutch can be held in the engaged state regardless of the rise of the reaping section, so that the desired high mowing work can be reliably and easily performed.
