    • PROBLEM TO BE SOLVED: To provide a working vehicle having simple construction for allowing the self-propelling movement of a vehicle body in a backward boarding fashion. SOLUTION: The working vehicle comprises a hydrostatic continuously variable transmission 16 for transmitting engine output to travelling devices 1, 2, and a change pedal mechanism 30 for speed change operation of the hydrostatic continuously variable transmission 16. A travel lever 50 is provided at the rear part of the vehicle body. A mechanical interlocking mechanism 25 is provided for interlocking the travel lever 50 with the change pedal mechanism 30 so that the hydrostatic continuously variable transmission 16 is operated via the change pedal mechanism 30 by the travel lever 50.

    • PROBLEM TO BE SOLVED: To enable the easy confirmation of changeover operation and the changeover position of an operation pattern changeover valve without difficulty in a circumstance that there is no other choice the changeover valve should be placed in a space under a floor near a foot on either right or left side of the operator. SOLUTION: A small hydraulic excavator comprises an upper part rotating body mounted to a lower part travelling body in a manner of being rotatable around a vertical shaft, a control valve unit 22 in which a plurality of control valves are unified, and the operation pattern changeover valve 23 for changing over patterns of the combination of an operation valve and the control valves which are arranged side by side in a front/back direction in a valve housing space 21 between an upper frame bottom plate 12 and a floor plate 13. In the small hydraulic excavator, the operation pattern changeover valve 23 is arranged in a manner that an upper surface including the operation lever 27 is inclined forward in a state of facing an operation port 30 formed at the floor plate 13.
