The present invention relates to an agricultural plastic paper coating machine, and more specifically, both ends 10b and 10c of the front support 10a have a connection portion 10e and 10f of the towing handle 10d and a nut 10g '. It is fastened with the fixing bolt (10h) is provided with the axial bolt (10g) and the nut (10h ') provided and the front support and " "A pair of guide transverse pipes (2) (2a) having a square hole formed in a direction perpendicular to the moving direction on the bottom of a flat plate (10) made of a rectangular plate connected in a shape is fixed by adjoining side by side at the same height. A main body having a pair of vinyl support rollers (1a) and (1b) installed thereon by forming a screw hole (2b) in the fixing bolt (2c) to be assembled with screws and maintaining a constant distance back and forth in the center of the flat plate. 1) and It is connected to the inner end of the rotary shafts 4a and 5a of the wheels 4 and 5 installed on both sides of the main body 1, and is formed into a rectangular rod body to penetrate the rectangular holes of the guide transverse tubes 2 and 2a into the guide transverse tubes. Wheel supports 4b and 5b which are inserted and fixed to the guide transverse pipes 2 and 2a by fixing bolts 2c inserted into the screw holes 2b formed inward from the outer surface of the guide transverse pipes； Fixing bolts in the guide tubes 60 and 60a and the threaded holes 61 formed in the guide tubes, in which rectangular guide holes are formed to fit the wheel supports 4b and 5b and slide in the longitudinal direction of the wheel supports. (62) are assembled and the fixing plates (63) and (64) are attached to the upper surface of the guide tube, respectively, to the same height as the supporting rollers (1a) and (1b) installed on the upper surface of the main body (1) on the upper surfaces of each fixing plate. A pair of supporting rollers 63a, 63b, 64a, 64b are installed, and vertical protrusion pieces 63c, 64c are
