SYSTEM AND METHOD OF VERTICAL SOIL TREATMENT WITH SHALLOW DISC BLADES Russian patent published in 2014 - IPC A01B7/00 A01B5/00 A01B21/08 A01B13/00 

FIELD: agriculture.

SUBSTANCE: tool comprises the front and rear rows of shallow concave disc blades. The front and rear rows of blades have respectively the front and rear right part and the front and rear left part, symmetrically located about the centre line of the tool. The rear right part is located behind the front right part on the right traffic lane, and the rear left part follows the front left part on the left traffic lane when the tool is moved along the field. The tool has no device coming in contact with the ground on the right traffic lane between the front right part and the rear right part, and no device coming in contact with the ground on the left traffic lane between the front left part and the rear left part. The shallow concave disc blades have the concavity of approximately 31.75 to 42.9 mm with the outer diameter of approximately 508 mm. The front left part and the front right part and/or the rear left part and the rear right part are located at an angle of approximately 18 degrees relative to a line perpendicular to the centre line. The concave disc blades are grooved.

EFFECT: constructive implementation enables to improve the quality of soil treatment at high speeds of the tool movement.
