Description

[Detailed explanation of the invention] (Industrial application field) The invention is a mobile agricultural machine, more specifically, the machine body is equipped with an engine and a transmission case, as well as a battery and starter motor, and the starter motor is operated by operating a key switch. This invention relates to a cell-startable mobile agricultural machine that can be driven to start the engine.

(Prior Art) Conventionally, not only riding-type mobile agricultural machines but also walking-type mobile agricultural machines are known that are equipped with a battery and a starter motor to enable cell start.

In a walk-behind mobile agricultural machine, for example, as shown in Japanese Utility Model Application Publication No. 61-59173, a key switch for starting the starter motor is provided on a handle frame with a handle so that it can be operated at hand. A harness is interposed in connection with the starting motor, and since the walk-behind mobile agricultural machine allows the handle frame to rotate and has versatility, the harness is connected to the handle frame and the machine body in detail. is located outside the engine and transmission case.

(Problems to be Solved by the Invention) However, when the harness is installed in an exposed state as described above, there is a problem that it may be damaged by contact with external objects, and the handle frame may be rotated. In this case, it is necessary to set the harness to a length that can accommodate the turning, which increases the length of the harness, which increases the cost accordingly, and there is a problem that the surplus portion of the harness becomes tangled after the turning.

An object of the present invention is to ensure protection of the harness and to minimize the length of the harness even when the handle frame is rotated.
