The present invention further combines auxiliary blades at both ends of the feed screw shaft for transferring the compost loaded in the loading box to the spraying port side, so that the remaining amount of compost between the screw and the side wall of the front and rear of the loading box can be minimized. Of course, by installing an auxiliary beater on the inner bottom of the angle adjustment plate to prevent the compost to stick to the angle adjustment plate, to ensure that the compost can be scattered smoothly, the connection portion with the PTO shaft for receiving power from a moving means such as a tractor By installing a multi-layer flange and fixing it with pins, it is possible to prevent damage to the PTO shaft or gears due to overload during power transmission, and it is related to a compost spreader that can be easily replaced even if the shaft is damaged. . The present invention for achieving the above object is formed in the shape of a rectangular box having an open top surface is formed with a loading space (2) for loading the compost inside, the lower side of one side spraying for spraying the loaded compost A loading box 2 in which 3 is formed； It is rotated by receiving the driving force from the gear group connected to the main shaft (5) that is connected to and installed with the PTO shaft (4) of the moving means, such as a tractor, is installed in the transverse direction (1) in the transverse direction and rotated to cross each other A pair of conveying screw shafts 7 for conveying the compost loaded through the plurality of screws 6 fixedly installed on the outer circumferential surface of the sprinkling hole 3； Compost spreader for spraying compost made of a beater (8) for spraying the compost transported to the sprayer (3) through a screw (6) is installed at the lower end of the sprayer (3) installed on one side of the loading box (1) To Coupling piece 10 is installed to protrude on both ends of the transfer screw shaft (7) for transporting
