A bulldozer comprises a blade, an engine, a selective catalytic reduction device, a reducing agent tank, and a cab. The engine is disposed behind the blade. The selective catalytic reduction device treats exhaust from the engine. The reducing agent tank stores a reducing agent to be supplied to the selective catalytic reduction device. The cab is disposed behind the engine. The reducing agent tank is disposed on a first side of a lower part of the cab. At least a part of the reducing agent tank overlaps the cab as seen in a top view.
