Abstract
A work vehicle is provided with an engine, a variable displacement hydraulic pump, a hydraulic motor, a traveling apparatus, an exhaust treatment device, a reductant supply route, a controller, and an operation member. The variable displacement hydraulic pump is configured to discharge hydraulic oil when driven by the engine. The exhaust treatment device is configured to treat the exhaust from the engine. The reductant supply route supplies a reductant to the exhaust treatment device. The controller is configured to set an engine speed to a low idle when the reductant supply route gets into an abnormal state. The operation member is configured to indicate a change of a discharge capacity of the variable displacement hydraulic pump so that the travel speed of the traveling apparatus becomes a predetermined speed or greater when the reductant supply route gets into an abnormal state.
