PROBLEM TO BE SOLVED: To make a hydraulic system from a hydraulic power source leading to each hydraulic system as simple and short as possible, in a work vehicle such as a tractor.SOLUTION: A work vehicle 1 includes: an engine 5 mounted on a travel machine 2 supported by travelling parts 3, 4; a transmission case 17 incorporating a hydraulic continuously variable transmission 500; and a rear travelling part 4 provided on left and right both sides of the transmission case 17 via a rear axle case 19. Left and right brake mechanisms 563 are arranged in the transmission case 17. On an upper surface of the transmission case 17, a hydraulic lifting mechanism 22 is mounted. It includes a pair of brake cylinders 630 and a pair of automatic brake valves 631. The pair of brake cylinders 630 and the pair of automatic brake valves 631 are assembled to a brake control case 664 and unitized, and the brake control case 664 is arranged on further front side than the hydraulic lifting mechanism 22 out of the upper surface of the transmission case 17.SELECTED DRAWING: Figure 28 |
