1. A transmission of an agricultural working vehicle, the transmission comprising:
a preceding transmission input shaft configured to rotate due to driving transmitted from an engine;
a first preceding transmission shaft configured to perform shifting with respect to driving of the preceding transmission input shaft and to output the shifted driving;
a first succeeding transmission shaft configured to be selectively connected or disconnected to the first preceding transmission shaft;
a first clutch unit configured to selectively connect or disconnect the first preceding transmission shaft to the first succeeding transmission shaft;
a second preceding transmission shaft disposed to be parallel to the first preceding transmission shaft and configured to perform shifting with respect to the driving of the preceding transmission input shaft and to output the shifted driving;
a second succeeding transmission shaft disposed to be parallel to the first succeeding transmission shaft and configured to be selectively connected or disconnected to the second preceding transmission shaft;
a second clutch unit configured to selectively connect or disconnect the second preceding transmission shaft to the second succeeding transmission shaft;
a succeeding transmission output shaft configured to perform shifting with respect to driving of the first succeeding transmission shaft or driving of the second succeeding transmission shaft and to output the shifted driving;
a first adjustment shaft coupled to the first clutch unit;
a first adjustment input gear coupled to the first adjustment shaft and configured to rotate as the first adjustment shaft rotates;
a first adjustment output gear engaged with the first adjustment input gear and coupled to the first succeeding transmission shaft;
a second adjustment shaft disposed to be parallel to the first adjustment shaft and coupled to the second clutch unit;
a second adjustment input gear coupled to the second adjustment shaft and configured to rotate as the second adjustment shaft rotates; and
a second adjustment output gear engaged with the second adjustment input gear and coupled to the second succeeding transmission shaft;
wherein, even when both the driving of the first preceding transmission shaft and the driving of the second preceding transmission shaft are outputted, the succeeding transmission output shaft outputs the shifted driving after the driving is selectively inputted to the first succeeding transmission shaft or the second succeeding transmission shaft since the first clutch unit and the second clutch unit selectively transmit the driving,
wherein a gear shifting rate between the preceding transmission input shaft and the first preceding transmission shaft is the same as a gear shifting rate between the preceding transmission input shaft and the second preceding transmission shaft.
