TRAILED SOLI-TILLING UNIT Russian patent published in 2006 - IPC A01B7/00 

FIELD: agricultural engineering; disk tillers.

SUBSTANCE: proposed unit contains main frame resting on wheeled running gear whose position is set by hydraulic cylinder. Two rows of section frames with curvilinear disks, attachments for cleaning concave plane of curvilinear disks are arranged on main frame symmetrically to longitudinal axis in crosswise manner. Curvilinear disk mounted on bracket with bearing unit is arranged behind first row of section frames in middle part. Connecting device is installed before main frame. Each curvilinear disk on section frames is fitted at angle on fixed bracket with bearing unit, and axles of rotation of curvilinear disks are arranged with slope to horizontal, axles of rotation of curvilinear disks on each section are parallel.

EFFECT: reduced energy consumption at soil tillage and wear of disks.
