The invention relates to a rotary harrow (roller) with helical leaf spring (4) for soil cultivation combinations. Machine combinations that can perform more than one operation in one pass are important in terms of reducing soil cultivation costs in agricultural production. Rotary harrow with helical leaf spring acting as the last operator in a combination mixes the soil and the plant residues homogenously in a stubble, and has a structure which does not spoil the evenness of the field through its special spring arrangement, and which breaks up the surface soil and performs a flexible compaction on the surface, not at the bottom.
