PROBLEM TO BE SOLVED: To provide a work vehicle capable of ensuring safety during a reverse operation while a PTO is rotating. SOLUTION: In a work vehicle that transmits a driving force of an engine to a PTO shaft that interlocks a traveling transmission and a working machine, a reverse operation is performed in association with a reverse side operation of a forward/reverse pedal linked to the traveling transmission. An engine is provided when the reverse drive detecting means 36, 36A for detecting is provided, and the PTO clutch means for turning on/off the power to the PTO shaft is provided, and when the reverse drive detecting means 36, 36A detect the reverse drive side operation when the PTO clutch means is in the ON state. A reverse engine stop mode is provided to stop the engine. Further, even when the PTO clutch means is in the engaged state and the reverse drive detecting means 36, 36A detect the reverse drive side operation, the reverse drive engine stop mode release switch 51 is configured to continue driving the engine.
