1. A transmission apparatus of an agricultural vehicle, comprising:
a leading transmission part which shifts power transmitted from an engine of an agricultural vehicle;
a clutch part connected to the leading transmission part to selectively output power transmitted from the leading transmission part;
an adjustment part connected to the clutch part; and
a following transmission part connected to the adjustment part to shift power transmitted from the adjustment part,
wherein the leading transmission part includes a first leading transmission unit which shifts the power transmitted from the engine and a second leading transmission unit which shifts the power transmitted from the engine,
the clutch part includes a first clutch unit connected to the first leading transmission unit to selectively output power transmitted from the first leading transmission unit and a second clutch unit connected to the second leading transmission unit to selectively output power transmitted from the second leading transmission unit,
the adjustment part includes a first adjustment unit connected to the first clutch unit, a second adjustment unit connected to the second clutch unit, and an integration unit connected to both the first adjustment unit and the second adjustment unit, and
the following transmission part includes one following transmission unit connected to the integration unit,
wherein:
the leading transmission part includes a leading transmission input unit which transmits the power transmitted from the engine to each of the first leading transmission unit and the second leading transmission unit;
the leading transmission input unit includes a plurality of leading transmission input gears which are engaged with a plurality of first leading transmission gears included in the first leading transmission unit and a plurality of second leading transmission gears included in the second leading transmission unit, and a leading transmission input shaft which is rotated by the power transmitted from the engine, the leading transmission input shaft rotates the leading transmission input gears and rotates the first leading transmission gears and the second leading transmission gears through the leading transmission input gears; and
the first leading transmission gears and the second leading transmission gears, which are engaged with one sides and the other sides of the leading transmission input gears, are formed to be the same to shift power at the same gear shift ratio,
wherein the integration unit is connected to:
the first adjustment unit to shift power at a first gear ratio; and
the second adjustment unit to shift the power at a second gear ratio which is different from the first gear ratio.
