FIELD: agriculture. ^ SUBSTANCE: ridge former contains passive working elements, active working element for formation of inner part of ridge, ridge-forming plate, covering cutter, casing and profiling planker. Passive working elements are made in the form of section of mouldboard hillers; at that, size of each next one is larger than that of the previous one. Active working element is made in the form of cone-shaped loosening cutters located at an angle to direction of movement and to horizontal plane. Cutter located under covering cutter includes shaft located horizontally along movement direction and blades are fixed on it. Guide shields are mounted on inner part of casing. ^ EFFECT: design will allow improving the quality of formed ridges during potato cultivation in climatic zones with insufficient moistening, owing to creating the ridge of aggregate structure and avoiding moisture losses during its formation. ^ 2 dwg |
