Kind Code:
A1
Abstract:
A working vehicle, wherein flows of hydraulic oil delivered under pressure from two or more hydraulic pumps are joined together and the joined hydraulic oil can be taken out.
A working vehicle is provided with two hydraulic pumps independent of each other and adapted to deliver hydraulic oil under pressure, a mode switching valve (230) capable of being switched to a flow joining position (K) at which flows of the hydraulic oil delivered under pressure by the two hydraulic pumps are joined together, PTO ports (260, 261) out of which the hydraulic oil is taken, and a PTO switching valve (240) provided downstream of the mode switching valve (230) and switching flow of the hydraulic oil so that the oil can be delivered under pressure to the PTO ports (260, 261).
