ジンを始動させたような際、刈取部が不測に作動
して怪我をするなどの危険があつた。 In this type of combine harvester, the fixed connection between the rear body and the reaping section is released, and the reaping section is moved forward and away from the rear body, thereby creating a sufficiently wide space between the two. Maintenance and inspection of the engine and traveling transmission case located at the front end of the machine, or the reaping device and vertical conveyance device located at the rear end of the reaping section, will not be obstructed by the reaping section or the rear fuselage. However, even when the reaping section is moved forward in this way, the transmission device from the rear body to the reaping section remains in the transmission state. When you want to manually move operating parts such as the reaping device of the reaping section or the vertical conveyance device, it takes a lot of effort to manually operate them, and moreover, a third party can accidentally start the engine. When the machine was started, the reaping section would operate unexpectedly, posing a risk of injury.

に切換えるべく構成してあることを特徴とする。 In view of the above-mentioned circumstances, an object of the present invention is to enable easy and safe manual operation of various devices during maintenance. The present invention is characterized in that the transmission device from the rear body to the reaping section is automatically switched to a non-transmission state in conjunction with the forward movement of the section.

行ない得るに至つた。 That is, when the reaping section is moved forward and away, the power transmission from the rear body to the reaping section can be automatically cut off. It is easy to move, especially when you want to move it by hand for lubrication, and even if a third party accidentally starts the engine, there is no risk of the reaping part operating unexpectedly, and the desired result can be maintained. Maintenance can now be carried out safely and easily.
