PROBLEM TO BE SOLVED: To provide a working vehicle which can make a worker sense lowering of output horsepower irrespective of a work mode at which the worker performs work according to a state of a reductant or the like.SOLUTION: A working vehicle having a plurality of work modes at which a worker can perform work corresponding to a load state includes an engine, an exhaust emission control device, a reducer tank, a state determination part, and an engine control part. The exhaust emission control device cleans a nitrogen oxide in an exhaust gas discharged from the engine. The reducer tank accumulates a reducer which is supplied to the exhaust emission control device. The state determination part determines a state of the reducer accumulated in the reducer tank. The engine control device controls an output of the engine according to the state of the reducer which is determined at the state determination part, and when the state of the reducer becomes a reference value or lower, the control device controls the output of the engine by using a restricted operation engine output torque curve in which the output horsepower of the engine becomes smaller than the output horsepower of the engine when each of a plurality of the work modes is selected. |
