Abstract

A work vehicle includes an engine, an injector injecting a reducing agent to an exhaust gas exhausted from the engine, a determination portion determining whether or not a temperature of the injector is high, a stop determination portion determining whether or not the engine has stopped while the injector is in a high-temperature state as a result of determination by the determination portion, a counter counting the number of times of stop of the engine while the injector is in the high-temperature state based on a result of determination by the stop determination portion, and a warning portion giving a warning in connection with stop of the engine when a count value of the counter exceeds a first prescribed value.
