Therefore, since the vehicle body cover is composed of two divided bodies, the die cost can be reduced as much as possible, and the connecting portion where the strength of the vehicle body cover is the weakest is usually used when the operator rides on the vehicle body cover. Since the front wheels, which are the heaviest on the axles, are arranged on the rear side of the axles so as to be spaced apart from each other, it is possible to secure sufficient mounting strength while reducing the weight of the vehicle body cover.

According to the second aspect of the present invention, in the rear split cover, both side portions of the portion rearward of the connecting portion are bulged in the left-right direction to form the cover extension portion, and the cover extension portion is formed. It is located behind the auxiliary step protruding from the fuselage frame.

Therefore, even when the fertilizer application device is mounted on the rear end of the rear split cover, the fertilizer application device does not interfere with the boarding / alighting operation, and the fertilizer application operation can be easily performed. It can be carried out. Also, if the cover extension is wider than the front of the auxiliary deck, the auxiliary deck will also be wider, and the auxiliary deck is cantilevered, so it is necessary to increase the weight in order to ensure strength, and to load it onto the truck. When doing so, there is a possibility that the truck hits the tilted door and cannot be loaded, but in the present invention, the above-mentioned problems can be eliminated as much as possible.
