Abstract: Provided is a work vehicle capable of satisfying a user's demand to brake performance in a flexible manner. A wheel loader 1 comprises a controller 5 storing a plurality of control characteristics each of which is set such that a brake valve control pressure Pi of a solenoid proportional valve 45 increases as a pedal angle θ of a brake pedal 43 increases, and under the condition where a pedal angle θ is equal to or less than a predetermined pedal angle θ, an increase rate of the brake valve control pressure Pi with respect to the pedal angle θ varies. In a case where the pedal angle θ detected by a potentiometer 33 is equal to or less than the predetermined pedal angle θth, the controller 5, calculates the brake valve control pressure Pi based on the selected one control characteristic.
