Description

The present invention relates to an agricultural work machine including a battery. For example, an agricultural work machine (“combine” in the literature) equipped with a battery is known (see Patent Document 1). In agricultural work machines, batteries are used as a power source for electrical components such as engine starting motors and headlights. It is a side view which shows the whole of the farm work machine.It is a top view which shows the whole of the farm work machine.It is a rear view which cut out a part of the agricultural work machine.It is a partial side sectional view of the agricultural work machine.It is a rear perspective view of the battery mounting part.It is a front view of the battery mounting part.It is a schematic diagram which shows the current circuit between a battery and an electric component. An embodiment of the agricultural work machine according to the present invention will be described with reference to the drawings. 1 and 2 show the entire head-feeding combine, which is an example of an agricultural work machine. The combine of the present embodiment performs harvesting work of rice, wheat and the like. In the following description, regarding the traveling aircraft of the combine, the direction of the arrow F shown in FIGS. 1 and 2 is "front of the aircraft", the direction of the arrow B is "rear of the aircraft", and the direction of the arrow U shown in FIG. The direction of the arrow D is "above the aircraft", the direction of the arrow D is "below the aircraft", the direction of the arrow L shown in FIG. 2 is "left of the aircraft", and the direction of the arrow R is "right of the aircraft".
