FIELD: agriculture.

SUBSTANCE: cultivator for processing seed potato plantings contains a cross bar, support wheels, parallelogram sections, a plow beam with a gauge wheel, guide brackets rigidly fixed to the beam and equidistant from the cross bar, and holders installed in the guide brackets at an equal distance from the longitudinal axis of symmetry of the beam with the possibility of adjusting this distance. The holders are equipped with toothed disk working bodies. Parallelogram sections are two alternating parallelogram sections for surface treatment between ridges and in a ridge. The parallelogram section for surface treatment between the ridges is equipped with toothed disk working bodies, which are arranged in pairs at an equal distance from the longitudinal axis of symmetry of the beam and fixed at an angle of 34° relative to the vertical component of the beam to the stand with the holder. Each toothed disk working body on the beam is set at an angle of 5° to the direction of travel to converge to each other. A pointed share 35 cm wide is installed between the toothed disc working bodies. Parallelogram sections for surface treatment in the ridge are equipped with pointed shares 30 cm wide. EFFECT: weeds are trimmed when planting potatoes for seeds in two rows in the ridge, soil clods are destroyed, and ridge arches are strengthened.
