Abstract: To provide a working vehicle with a simple body structure, an HST case containing a hydraulic stepless transmission is disposed between an engine adjacent one end in a fore and aft direction of a vehicle body, and a propelling transmission case disposed adjacent the other end in the fore and aft direction. The HST case, with the engine and propelling transmission case, forms the vehicle body. With this construction, a driving deck is located at a relatively low level so that the driver may board and alight from the deck with ease. Despite the low level of the deck, the bottom of the vehicle body is at a relatively high level to be free from contact with projections on unleveled terrain. Frame strength may be increased where the HST case is connected between a main clutch housing connected to the rear of the engine and the propelling transmission case.
