The present invention provides a method and a device for controlling the disposal of a compost and a method of disposing of a compost, The present invention provides a manure spreader in which convenience of power transmission operation is ensured. The above object of the present invention is achieved by a Viterbor assembly 160 assembled in a standing state by an axial pin at equal intervals of 120 degrees between upper and lower discs so that compost comes into contact with a large- Wherein the beater blade assembly of the first beater blade assembly and the beater blade assembly of the second beater blade assembly are disposed such that they are superimposed on each other without rotation interference, The compost spraying means 100 and the frame housing elevating apparatus 170 provided on both sides of the frame housing are provided with a discharge port for loading the compost sprinkling means in the upward rotation about the hinge axis formed on both sides of the top of the loading box And a drive shaft clutch head engaged with the clutch head of the input shaft and connected to the power transmission of the manure spreading means by a downward in- A drive spline shaft formed in the front and rear bearing bases formed at the same interval in the circumferential direction so as to be engaged with key projections formed on the inner circumferential surface of the head, And a stop ring which is assembled to the end of the drive spline shaft by a bolt screwed in a state of being in tight contact with the inner end of the drive shaft clutch head, And a power transmission device (400) for controlling the driving of the compost sprinkling means by a clutch operation.본 발명은 퇴비살포에 따른 분쇄력 증대 및 부하의 최소화에 의한 이물질의 배출이 용이하여 동력전달계통의 무리한 부하 감소로 수명이 보장되고 적재함의 퇴비 적재 및 청소에 따른 퇴비살포수단의 개방 및 청소 후에 동력전달 동작의 편리성이 보장되는 퇴비살포기를 제공한다.본 발명의 상기 목적은, 판상의 비터날이 넓은면에 퇴비가 접촉하도록 상, 하부 원판디스크 사이에 120도 등분간격으로 축핀에 의해 기립 상태로 조립된 비터날 조립체(160)가 상기 제1, 제2 비터축에 일정간격을 갖고 조립되되, 상기 제1비터축의 비터날 조립체와 제2비터축의 비터날 조
