FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building. Chopper-spreader of solid organic fertilizers comprises a hopper with a feeding horizontal conveyor located therein. Above the conveyor there is a shredding rotor from the side of outlet, under which an adjustable concave is installed. Feeding horizontal conveyor is made by chain-and-slat with slats of circular cross-section. Checkerboard cutting discs are mounted on the slats by sliding bearings. Shear arcs constructed along parabolic curves are installed on the adjustable concave. Cutting discs on the shredding rotor are placed along the screw lines, from the center of the rotor having a left-sided direction and right-sided direction.
EFFECT: uniform distribution of organic fertilizers along the field surface is provided.
