COMBINED TILLAGE TOOL Russian patent published in 2006 - IPC A01B49/02 

FIELD: agricultural engineering.

SUBSTANCE: tillage tool has frame with carrier wheels, regulation mechanism, disk batteries, flat hoes, bladed drum, and toothed bar roller. Line of arrangement of outer disk batteries is offset rearward from line of arrangement of middle disk batteries by distance equal to 3/4 the diameter of disk. Front carrier wheels are located in spare sites. Bladed drum and toothed bar roller are positioned in staggered arrangement, i.e., sections of one working tool overlap spaces between sections of other working tool. Bladed drum and toothed bar roller shafts are rigidly coupled through underframe in intervals between sections. Hydraulic cylinder positioned in center of symmetry of underframe is adapted for moving working tools from operating position to transport position, and vice versa. Additional disk battery is axially positioned between outer disk batteries so that disks of additional disk battery are oriented with their convexities toward reverse side with respect to disks of forwardly arranged middle disk battery.

EFFECT: improved quality of tillage and reduced dimensions of tillage tool.
