FIELD: agriculture; engineering.
SUBSTANCE: chopper spreader includes a body mounted on the chassis with the feed conveyor and provided with a pulverized body is installed downstream of the input conveyor. Grinding body is in the form of two counter rotating drums knife set at an angle to the horizontal plane. At the bottom of the cutter drum below the bottom of a body closed knife drums with grooved sidewall. With the end surface of the drum covered trellis concave. Knives cutter drum mounted on the supporting disk and executed on a logarithmic spiral. Height "h" of the knife at the required size of the ground particles. Front and rear edge of the knife are rounded to the radius. Drive supply conveyor is made by the PTO shaft of the tractor through the gearbox. Drive knife drums made from hydraulic motors are aggregated tractor.
EFFECT: in so doing increases the productivity and the uniformity of distribution of fertilizer in the field.
