PROBLEM TO BE SOLVED: To provide an agricultural working vehicle improved in traveling performance and speed change operability.SOLUTION: This agricultural working vehicle comprises: a traveling vehicle 1 mounted with an engine 2; a hydraulic speed change mechanism 57 of a type of a hydraulic pump 85/hydraulic motor 86 for speed-changing the power of the engine 2; a planetary gear mechanism 83 for synthesizing a rotation force in one direction from the engine 2 and a speed change output from the hydraulic motor 86 in the hydraulic speed change mechanism 57; and a transmission case 4 having a synthetic output shaft 84 to which a synthetic output of the planetary gear mechanism 83 is transmitted as the rotation force in one direction. In the agricultural working vehicle for transmitting the rotation force in one direction in the synthetic output shaft 84 to a traveling output shaft 63, an output to the synthetic output shaft 84 is changed by output-controlling the speed change output from the hydraulic motor 86 in forward/reverse directions. |
