A radiator is arranged behind an engine, a selective catalytic reduction apparatus, and a connecting pipe. A partition wall partitions first and second accommodation spaces. The engine, the selective catalytic reduction apparatus, and the connecting pipe are arranged in the first space. The radiator is arranged in the second space. A reducing agent tank is arranged behind the partition wall. A reducing ejection apparatus attached to the pipe ejects reducing agent into the pipe. A reducing agent hose connects the tank and the apparatus. The hose has a boundary portion positioned at a boundary between the first and second spaces. A height position of the boundary portion is between top and bottom sections of the connecting pipe. The boundary portion and the reducing agent ejection apparatus are arranged on a left or right side of a center line extending in a front and back direction of the partition wall.
