The present invention relates to a management machine provided with a clutch lever for operating the clutch via a side operation wire.

(Prior Art) Conventionally, when operating a clutch of a working machine mounted on a management machine, a clutch lever is provided at a proximal portion of a steering handle of the management machine, and the clutch lever and the clutch of the working machine are operated by an operating wire. That is, the clutch of the working machine was operated by connecting with.

(Problems to be solved by the invention) By the way, the management machine described above is mainly used for management work in an orchard or a small condominium in a mountainous area because the management machine itself is small and convenient. Therefore, in consideration of the ease of maneuverability, it is usual that the management machine can be maneuvered from both front and rear directions by moving the steering handle of the management machine back and forth.

In that case, a problem arises in the length of the operation wire installed between the management machine and the working machine.

That is, when the handle of the management machine is moved back and forth, the handle is moved horizontally in a clockwise or counterclockwise direction with the mounting portion of the handle attached to the management machine body as a fulcrum.

Therefore, with the movement of the handle, it is necessary that the length of the operation wire, which is arranged substantially in parallel with the handle, has a margin sufficient to follow the movement of the handle. As a result, when the handle is attached to the normal position, the operation wire may be slackened more than necessary and may be caught in a part of the machine or a crop, which may cause troubles in performing farm work. There was a problem to succeed.

Further, in the management machine used for multiple purposes, various work machines are prepared as attachments, and each of the work machines operates a mechanism for performing its function.
An operating wire is used. However, one end of the operation wire is connected to the clutch lever of the management machine and the other end is connected to the working machine so that the working machine is operated. However, when connecting the operation wire, one end of which is connected to the management machine, to the working machine, there is a difference in structure and shape of the working machine. However, the operating wire from the management machine to the working machine has to be attached and detached from the connecting portion on the management machine side every time the working machine is replaced. was there.

The present invention has been devised in view of the above problems, and its purpose is to attach a work machine having a clutch to the rear part of the management machine main body in a detachable manner, and to connect the main body side operation wire to the hand side of the control handle. In a management machine provided with a clutch lever for operating the clutch via a wire, even when the handle is moved in the front-rear direction, the length of the wire can be minimized, and the work machine is different. Even if the wire is replaced with a new one, part of it can be left attached to the main body of the management machine without removing the entire wire, and the operation wire on the working machine side can be easily connected to the wire on the main body that remains on the main body of the management machine. It is possible to easily connect the clutch lever of the main body of the management machine and the clutch of the working machine by the operation wire.
