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.
