TILLAGE TOOL Russian patent published in 2007 - IPC A01B73/00 A01B59/42 

FIELD: agricultural engineering, in particular, surface soil tillage equipment.

SUBSTANCE: tillage tool has tractor and sequentially arranged multiple-section leveler designed so as to move sections to transport position for movement on roads, and mellowing units mounted on lower horizontal strips of rear section profiles. Leveler central section has carrier wheels and turnbuckles for fixing of left-hand and right-hand side sections in their transport position. Pulling-and-transporting beam is positioned in central section for movement in plane of symmetry of tillage tool by means of hydraulic drive. Bases of hydraulic cylinders of hydraulic drive are connected to front end of pulling-and-transporting beam. Hydraulic cylinder stems are connected to brackets of middle left-hand and right-hand side sections. Mellowing units are arranged in groups connected through flexible tie-rods to respective pulling bars positioned on middle and outer leveler sections.

EFFECT: improved quality of soil tillage and reduced labor intensity for moving outer and middle sections to working and transport position.
