Abstract
A work vehicle according to the present invention includes an engine installed in a traveling machine body supported by traveling units, and a transmission case incorporating a hydraulic continuously variable transmission. The transmission case incorporates a forward/backward traveling switching mechanism. The work vehicle includes forward traveling valves for forward traveling hydraulic clutches, a backward traveling valve for a backward traveling hydraulic clutch, and a master valve configured to control hydraulic oil supplying to the forward traveling valves and the backward traveling valve. A part of a hydraulic circuit is formed on a front lid member of the transmission case. The forward traveling valves, the backward traveling valve, and the master valve are attached on a front surface side of the front lid member.
