Patent number: 8007403Abstract: A work vehicle includes a hydraulic stepless speed changing apparatus and a gear type speed changing apparatus operable to receive output from the hydraulic stepless speed changing apparatus to convert it into a plurality of stages of speed. A return oil passage connected to a high-pressure side circuit of the hydraulic stepless speed changing apparatus is connected to a hydraulic tank. The return oil passage incorporates an unload valve and a throttle valve, between which an operably coupling mechanism is provided. This operably coupling mechanism switches over the unload valve to an unload condition in response to an operational displacement of a brake operating member for operating a brake to its braking side.Type: GrantFiled: September 4, 2008Date of Patent: August 30, 2011Assignee: Kubota CorporationInventors: Yuuki Ishida, Hiroshi Shimada, Koji Nada, Masaru Nakaji, Hiroki Bessho, Masatake Murakawa, Yasunobu Nakatani
