PROBLEM TO BE SOLVED: To provide a working vehicle such as a rice transplanter, a tractor, a combine or a construction engineering machine having a continuously variable hydraulic gear change mechanism and a planetary gear mechanism.SOLUTION: A working vehicle comprises: an engine; a continuously variable hydraulic gear change mechanism; a planetary gear mechanism which inputs rotation power from the engine and rotation power from the continuously variable hydraulic gear change mechanism, and synthesizes them; and a forward/reverse switching mechanism which inputs the synthesized rotation power from the planetary gear mechanism. The planetary gear mechanism is constituted so as to increase a rotation speed of the synthesized rotation power to a one-way maximum rotation speed from zero following that the continuously variable hydraulic gear change mechanism is gear-changed to a forward direction maximum rotation output state from a reverse direction maximum rotation power output state via a neutral state at the zero of an output. |
