摘要： There is provided a working vehicle having first and second hydraulic pump units operatively driven by a driving source and arranged away to each other in a width direction of the vehicle. 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.

摘要： A transmission for a working vehicle for transmitting drive power from an engine to a driving axle that includes: a flywheel including a flywheel body operatively connected with the engine and a flywheel housing for accommodating the flywheel body; a main-speed-change unit including a main-input shaft operatively connected with the engine via the flywheel body and a main-output shaft for outputting drive power to be transmitted to the driving axle; and a sub-speed-change unit including a sub-input shaft and a sub-output shaft, and disposed at a distance from the main-speed-change unit. The engine, the flywheel and the main-speed-change unit are integrally connected with each other so as to vibrate freely relative to a vehicle frame, and the main-output shaft of the main-speed-change unit is operatively coupled with the sub-input shaft of the sub-speed-change unit via a vibration-absorbing shaft coupling.
