WORKING TOOL OF TILLAGE APPARATUS Russian patent published in 2002 - IPC

FIELD: agricultural engineering. SUBSTANCE: working tool has tine mounted on frame. A-hoe is installed on tine end and flat blade is attached in vertical position to A-hoe and tine so as to adjoin A-hoe chest and tine. During operation of tillage apparatus blade cutting edge is extending forward of A- hoe point to cut through weedage before A-hoe and tine come into engagement therewith. It reduces soil resistance against passage of tine through it and decreases soil scatter. Upper end of cutting edge extends beyond soil surface. It provides cutting through of weedage accumulated in front of blade due to permanent pressing down of weedage to soil surface by cutting edge. Blade cutting edge is made in the form of arc of circle. EFFECT: simplified construction and improved quality of soil tillage. 2 dwg
