PROBLEM TO BE SOLVED: To easily and reliably remove foreign matter such as a stone caught in a working unit, and to efficiently execute catch-removing work in a working vehicle having a PTO shaft for transmitting the power of an engine to the working unit and a PTO clutch for engaging/disengaging the power transmission to the PTO shaft in a transmission case. SOLUTION: An inversion changing mechanism for receiving the power branched from the downstream side of a PTO clutch 39 and an inversion clutch for engaging/disengaging the power transmission to the inversion changing mechanism are provided in a transmission case. The PTO clutch 39 is a wet type multiple disk clutch, and has a PTO clutch cylinder 122 for engaging/disengaging the clutch. When the inverse clutch is coupled, the PTO shaft is intermittently subjected to the inverse drive by repeating the coupling operation of the PTO clutch 39 by the PTO clutch cylinder 122.
