A four wheel drive working vehicle having a hydraulic block for covering one side of a propelling transmission case, an engine, and an HST attached to a side of the hydraulic block remote from the transmission case. The HST includes an input shaft for transmitting drive from the engine, and an output shaft extending through the hydraulic block for transmitting the drive to a transmission line in the transmission case. The vehicle further includes a drive transmission mechanism for selectively transmitting the drive from the transmission line to rear wheels, and a transmission shaft for transmitting the drive between the drive transmission mechanism and the transmission line in the transmission case. The drive transmission mechanism is attached to the side of the hydraulic block where the HST is attached. The transmission shaft extends through the hydraulic block.
