FIELD: agricultural engineering, in particular, soil tillage equipment used for cultivation of farm crops.
SUBSTANCE: tillage machine has frame, rake-type grid adapted for distributing straw over field in windrow spacings. Supporting-driving roller is arranged behind rake-type grid and is adapted for cutting part of straw by means of spines and for deepening cut straw into soil to plowing depth. Upon exit from under roller, straw is ground and mixed with soil. Rotavation drum knives provide for mellowing of soil behind roller. During operation with wet soil, roller spines and rotavation drum knives are mutually cleaned since said knives are positioned between said spines. Roller spines are made in the form of triangles whose one side is oriented in radial direction and other side is extending tangentially to roller circumference.
EFFECT: increased efficiency, uniform distribution of straw from straw windrows followed with grinding and embedding of ground straw, and improved quality of tillage.
