FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. Screw hiller consists of a shaft, two partial coils with the profile of the Archimedes spiral with a decreasing radius from start to finish, and a pitch of the first round, three times the pitch of the second, and the propeller-blade. And downstream of movement hiller supply cylindrical casing set at a minimum distance from the propeller-blade and two-centimetric clearance of uncultivated soil surface.
EFFECT: invention allows to push the soil from the scope of its interaction with the coils and improve the performance of agricultural equipment.
