PROBLEM TO BE SOLVED: To improve the arrangement of a hydraulic pump unit, and to enhance maintenance performance without impairing the balance of a machine body.SOLUTION: In a working vehicle having hydraulic motors Mr for driving left and right wheels 21, and making the hydraulic motors Mr rotationally interlock with each other by receiving the supply of pressure oil from a hydraulic pump unit P, an axle 20 which oscillates around a pivot shaft 19 while approximating a rear part of an engine 13 is arranged, the wheels 21, 21 are supported to both sides of the axle 20 in order to interlock with each other by a steering mechanism S, and the hydraulic pump unit P is arranged at an upper part of the axle 20. The hydraulic pump unit P can be supported by utilizing a frame portion which is rigidly constituted by a support constitution of the axle 20 and the pivot shaft 19. Furthermore, frame parts 16 which are connected to an engine 13, and oppose each other in the left-and-right direction are connected by a first plate 40 in the vertical direction, and the hydraulic pump unit P can be arranged in the vicinity of the engine 13 so as to be detachable in an upper part of the first plate. |
