    Abstract: A work vehicle includes a fixed hood covering a rear area of an engine compartment housing an engine and an engine accessory, a swing axis extending through the rear area of the engine compartment in a transverse direction of the vehicle, and a swing hood swinging around the swing axis between a closed position and an open position. The swing hood tucks the fixed hood inside the swing hood and thus covers the fixed hood in the open position, and covers a front area and a middle area of the engine compartment and overlaps with a front end portion of the fixed hood in the closed position.

    Abstract: A work vehicle is provided with fuel supply lines that include a first fuel supply line that connects a first fuel tank and a junction. A second fuel supply line connects a second fuel tank and the junction. A common supply line connects the junction and a diesel engine. A fuel pump is provided on the common supply line. A first check valve is installed on the first fuel supply line and opens in accordance with a pressure differential between a pressure in the first fuel tank and a pressure in the junction. A second check valve is installed on the second fuel supply line and opens in accordance with a pressure differential between a pressure in the second fuel tank and a pressure in the junction. A fuel return line returns excess fuel from the diesel engine to the first fuel tank and the second fuel tank.
