In the working vehicle, each of the first and second hydraulic pump units includes a pump body; a port block formed with an oil passage for supplying/discharging an operating fluid to/from said pump body; a pump case connected to the port block so as to define a pump body accommodating space for surrounding the pump body; and a pump shaft for rotatably driving the pump body, the pump shaft having an input end operatively connected to said driving source. A drain port for opening the pump body accommodating space outward and a charge suction port for drawing in an oil from an oil tank in order to supply a charge oil to a hydraulic circuit fluidly connecting with the corresponding hydraulic motor unit are provided respectively in first and second assemblies formed by the corresponding pump case and port block. The drain port is provided on a wall surface other than an opposing wall surface facing each other of the wall surfaces of said first and second assemblies when arranging the first and second assemblies so that the input ends of each pump shaft are directed in the same direction.
