Claim 13:
14. A transmission of an agricultural working vehicle, the transmission comprising:
a preceding transmission portion configured to perform shifting with respect to driving transmitted from an engine of the agricultural working vehicle;
an adjustment portion connected to the preceding transmission portion to perform shifting with respect to driving transmitted from the preceding transmission portion;
a clutch portion connected to the adjustment portion to selectively output driving transmitted from the adjustment portion; and
a succeeding transmission portion connected to the clutch portion to perform shifting with respect to driving transmitted from the clutch portion,
wherein the preceding transmission portion comprises a first preceding transmission unit configured to perform shifting with respect to the driving transmitted from the engine and a second preceding transmission unit configured to perform shifting with respect to the driving transmitted from the engine,
wherein the adjustment portion comprises a first adjustment unit connected to the first preceding transmission unit to perform shifting with respect to the driving transmitted from the first preceding transmission unit using a gear ratio and a second adjustment unit connected to the second preceding transmission unit to perform shifting with respect to the driving transmitted from the second preceding transmission unit using a gear ratio different from that of the first adjustment unit,
wherein the clutch portion comprises a first clutch unit connected to the first adjustment unit to selectively output driving transmitted from the first adjustment unit and a second clutch unit connected to the second adjustment unit to selectively output driving transmitted from the second adjustment unit, and
wherein the succeeding transmission portion comprises a first succeeding transmission unit connected to the first clutch unit to perform shifting with respect to driving transmitted from the first clutch unit and a second succeeding transmission unit connected to the second clutch unit to perform shifting with respect to driving transmitted from the second clutch unit,
wherein the first preceding transmission unit comprises a first preceding transmission shaft and a first preceding transmission gear which is coupled to the first preceding transmission shaft to be idly rotatable in order to rotate due to the driving transmitted from the engine,
wherein the second preceding transmission unit comprises a second preceding transmission shaft and a second preceding transmission gear which is coupled to the second preceding transmission shaft to be idly rotatable in order to rotate due to the driving transmitted from the engine,
wherein the first succeeding transmission unit comprises a first succeeding transmission shaft and a first succeeding transmission gear coupled to the first succeeding transmission shaft to be idly rotatable,
wherein the second succeeding transmission unit comprises a second succeeding transmission shaft and a second succeeding transmission gear coupled to the second succeeding transmission shaft to be idly rotatable,
wherein the first adjustment unit comprises a first adjustment input gear coupled to the first preceding transmission shaft and a first adjustment output gear engaged non-coaxially with the first adjustment input gear and coupled to a first adjustment shaft, and the first adjustment shaft is coupled to the first clutch unit,
wherein the second adjustment unit comprises a second adjustment input gear coupled to the second preceding transmission shaft and a second adjustment output gear engaged non-coaxially with the second adjustment input gear and coupled to a second adjustment shaft, and the second adjustment shaft is coupled to the second clutch unit,
wherein the first clutch unit is coupled to the first succeeding transmission shaft, and the second clutch unit is coupled to the second succeeding transmission shaft,
wherein a gear ratio of the second adjustment output gear to the second adjustment input gear and a gear ratio of the first adjustment output gear to the first adjustment input gear are different from each other.
