Abstract
To provide a work vehicle that can save space. [Solution] The system comprises a urea water tank 18 in which urea water is stored, and a urea water pump 19 that supplies the urea water from the urea water tank 18 to an exhaust gas purification device that purifies the exhaust gas of the engine. The urea water tank 18 has a pump housing recess 18b that houses at least a part of the urea water pump 19, and the pump housing recess 18b is formed on the side of the urea water tank 18 that faces outwards to the left and right sides of the vehicle body.
