Provided is a transmission for a tractor capable of accurate operation at an ultra-low speed and multistage transmission. The transmission of the present invention comprises: a forward and backward movement transmission unit (100) which outputs power of an engine, transmitted through an input shaft (Sa), as rotation in a forward or backward movement direction of a forward and backward movement shuttle shaft (130); an ultra-low speed transmission unit (200) which selectively outputs an ultra-low speed by making an output of the forward and backward movement shuttle shaft (130) pass through an ultra-low speed gear or preventing the output of the forward and backward movement shuttle shaft (130) from passing through the ultra-low speed gear; a main transmission unit (300) comprising a main transmission counter axis (310) which receives output of the ultra-low speed transmission unit (200), a main transmission axis (320) which outputs rotation of the main transmission counter axis (310) in a revolution number of multistage transmission, and multiple transmission gears which are installed on the main transmission counter axis and the main transmission axis and transmit a revolution number of the main transmission counter axis as output of multistage transmission to the main transmission axis; and a sub-transmission unit (400) comprising a spiral pinion (410) for outputting the rotation of the main transmission axis (320) in a rotation number of multistage transmission to a differential gear, and multiple transmission gears for performing multistage transmission from the main transmission axis to the spiral pinion.

    본 발명은 초저속의 구현이 정확하고 다단 변속이 가능한 트랙터의 트랜스미션을 제안한다. 본 발명의 트랜스미션은, 인풋샤프트(Sa)를 통하여 전달되는 엔진의 동력을 전후진 셔틀샤프트(130)의 전진 또는 후진 방향 회전으로 출력하는 전후진 변속부(100); 상기 전후진 셔틀샤프트(130)의 출력을 초저속기어를 경유하거나 경유하지 않도록 함으로써, 선택적으로 초저속 출력을 출력하기 위한 초저속 변속부(200); 상기 초저속 변속부(200)의 출력을 받는 주변속카운터축(310)과, 주변속카운터축(310)의 회전을 다단으로 변속된 회전수로 출력하는 주변속축(320), 그리고 상기 주변속카운터축과 주변속축에 각각 설치되어 주변속카운터축의 회전수를 다단으로 변속되는 출력으로 주변속축으로 전달하는 다수의 변속용 기어를 포함하는 주변속부(300); 그리고 상기 주변속축(320)에서의 회전을 다단으로 변속된 회전수로 차동장치로 출력하기 위한 스파이럴 피니언(410)과, 상기 주변속축에서 스파이럴 피니언으로의 다단 변속을 수행하기 위한 다수의 변속용 기어를 포함하는 부변속부(400)로 구성되고 있다.
