摘要： A work vehicle includes an engine, a selective catalytic reduction apparatus, a fuel tank, and a reducing agent tank. The selective catalytic reduction apparatus treats exhaust from the engine. The fuel tank includes a fuel tank body retaining fuel and a fuel supply port which supplies fuel to the fuel tank body. The reducing agent tank includes a reducing agent tank body retaining a reducing agent used in the selective catalytic reduction apparatus and a reducing agent supply port which supplies the reducing agent to the reducing agent tank body. The fuel supply port protrudes from the fuel tank body toward a first direction left or right with respect to a center axis line in the front and back direction of the vehicle. The reducing agent supply port protrudes from the reducing agent tank body toward a second direction opposite to the first direction.
