SUBSURFACE PLOW Russian patent published in 1995 - IPC

FIELD: agricultural engineering. SUBSTANCE: plow comprises two frames arranged at an angle to its longitudinal axis and carrying plow bottoms. First bottoms, as the plow moves, are for throw-in plowing and the following bottoms, for throw-out plowing. The rod link is formed between the last plow bottoms so that their furrows are covered with soil moved from the field surface by back-filling devices. The last plow bottoms are followed by moldless working tools so that their shares loosen the link soil while the supports secured on their shanks hold the link edges from falling until the furrows are completely back-filled with soil. EFFECT: improved design. 4 dwg
