By this ON state, the buzzer switch 70 of the ON-OFF switch type is turned on as shown in FIG.
A full alarm lamp 69 is turned on when an alarm is issued from 71.

Further, when the buzzer-stop switch 72 of the ON-OFF switch type is turned on, the generation of the alarm from the buzzer 71 is stopped, and the lighting of the full display lamp 69 is continued. Thus, when the buzzer stop switch 72 is turned on in the past, the alarm from the buzzer 71 is stopped and the full display lamp 69 is turned off. However, according to the present invention, only the alarm from the buzzer 71 is generated. Is stopped, it is easily understood that the battery is full, and the cost can be reduced.

A support plate 64 is provided below the panel 14d of the operating device 14a, as shown in FIG. 14, and a rear portion of a throttle lever 65 provided on the operating device 14a is attached to the supporting plate 64. Is the ACD relay (L)

As a result, shortening of each harness and facilitation of routing are achieved. When the engine 15 is emergency stopped, as shown in FIG. 15 and FIG. 16, the OFF operation of the main switch 66 activates the emergency stop switch 66b via the timer relay 66a. An engine stop motor operating relay 67a is operated via a motor relay contact 66c, and in conjunction with this operation, an engine stop motor 67b is operated.
The cover 15a of the engine 15 is operated to the stop position of the engine 15, and the engine 15 is stopped.

Thus, safety can be improved and a safe harvesting operation can be performed. Throttle lever 65 for changing the output speed of the engine 15 and performing an emergency stop, etc.
Is divided into three operations of an open position, a closed position (idling position), and a stop position of the engine 15, as shown in FIG. 16, and the engine 15 is controlled via a connection wire -65a. Conventionally, the engine 15 was stopped by an operator (operator) manually pulling the engine 15 to a stop position to stop the engine 15. However, according to the present invention, the circuit 15 shown in FIG. As described above, this operation is automatically stopped by the engine stop motor 67b.

Thus, safety can be improved and a safe harvesting operation can be performed.
