FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to machines for surface treatment of soil with spring-loaded working elements, namely to soil levellers. Spring alignment device comprises a frame with working members. Frame is connected to working members by means of C-shaped spring post, which in lower part is connected to channel by means of two bolt fixtures, channel is connected by means of two right and left bolt joints with stands of working elements, made in the form of right-side and left-sided flat-cutting hoes with longitudinal triangular ledges.
