WORKING TOOL FOR TILLAGE APPARATUS Russian patent published in 2006 - IPC A01B15/16 A01B23/06 

FIELD: agricultural engineering, in particular, equipment for tillage machines.

SUBSTANCE: tillage tool has flat disks with central mounting opening and annular circumferential cutting edge, and teeth provided on side surface. Teeth are made in the form of acutely sharpened small flat disks loosely put on shafts, which are rigidly and symmetrically attached to side surface of main disk at both sides thereof so that cutting edges of each small disk are arranged at the same level with cutting edge of main disk. Small disks have different diameters: half the disks have diameter twice the diameter of other half of the disks, said disks being arranged in alternation and at equal pitch with respect to one another. Small disks are spaced from main disk by distance half the distance of larger disks. All the disks are put on their respective shafts for rotation on roller bearings.

EFFECT: wider processing zone and provision for active tillage of soil by means of working tool.
