Abstract: A work vehicle includes an engine, an exhaust gas purification apparatus, a reducing agent tank, an engine coolant circuit, a branch path, a valve, an accepting portion, and a valve control unit. The exhaust gas purification apparatus purifies a nitrogen oxide in an exhaust gas. The reducing agent tank stores a reducing agent to be supplied to the exhaust gas purification apparatus. The engine coolant circuit includes a water pump for circulating a engine coolant through a circulation path as the engine is driven. The branch path is provided for heat exchange between the engine coolant and the reducing agent in the reducing agent tank. The valve controls supply of the engine coolant into the branch path. The accepting portion accepts an operation instruction from an operator. The valve control unit gives an instruction for an opening operation of the valve in response to the operation instruction from the operator.
