Abstract

A work vehicle according to the present invention has a plurality of work modes whereby it is possible to perform work in accordance with the load state said work vehicle being provided with an engine an exhaust gas treatment device a reducing agent tank a state determination unit and an engine control unit. The exhaust gas treatment device treats nitrogen oxides in the exhaust gas emitted from the engine. The reducing agent tank stores a reducing agent that is supplied to the exhaust gas treatment device. The state determination unit determines the state of the reducing agent stored in the reducing agent tank. The engine control unit controls the engine output according to the state of the reducing agent as determined by the state determination unit. When the state of the reducing agent is equal to or less than a reference value the engine control unit controls the engine output using a limited operation engine output torque curve such that the horsepower output by the engine becomes lower than the horsepower output by the engine when the respective work modes are selected.
