ABSTRACT:
A working vehicle comprises: a power source having an output shaft; axles; a cargo deck; and a transmission apparatus for driving axles disposed below the cargo deck. The transmission apparatus includes an input shaft drivingly connected to the output shaft of the power source, a hydro-mechanical stepless transmission driven by the input shaft, and a differential gear assembly differentially connecting the axles to each other. The hydro-mechanical stepless transmission includes a planetary gear assembly and a hydrostatic stepless transmission drivingly connected to the planetary gear assembly. The differential gear assembly is drivingly connected to the hydro-mechanical stepless transmission.
