    Abstract: A work vehicle includes a hydrostatic stepless speed changer device configured to speed-change driving power of an engine steplessly, a plurality of planetary gear speed changer devices configured to speed-change the driving power speed-changed by the stepless speed changer device, a plurality of clutch mechanisms corresponding to the plurality of planetary gear speed changer devices in order to take off the driving powers from these plurality of planetary gear speed changer devices individually, and a traveling speed changer device for speed-changing and transmitting the driving powers transmitted from the plurality of clutch mechanisms to a traveling mechanism. The plurality of planetary gear speed changer devices the plurality of clutch mechanisms and the traveling speed changer device are accommodated in a transmission case.
