TILLAGE APPARATUS Russian patent published in 2007 - IPC A01B35/00 A01B71/00 

FIELD: agricultural engineering, in particular, tillage technique.

SUBSTANCE: tillage apparatus has tractor, multiple-section leveler to be moved to transport position, and mellowing tools mounted on lower horizontal strips of rear profiles of said sections. Apparatus is further equipped with carrier wheels, pulling-transporting beam, towing shackle, drop-type support, blocking chain, mechanism for lifting of pulling-transporting beam, supporting bar, and retainers for retaining sections in transport position. Upon movement of leveler to transport position, left-hand and right-hand sections define closed spatial parallelepipeds held in fixed position on supporting bar by means of left-hand and right-hand retainers. Pulling-transporting beam lifting mechanism is positioned under said beam and comprises base with pivot axles at ends for accommodation of supporting wheels. Carrier bar is fixed by means of junction plates under pulling-transporting beam. Articulation linkage mechanism positioned between base and carrier beam comprises at least two pairs of pivotally connected crossing levers. Extension-type drive is made in the form of hydraulic power cylinders.

EFFECT: improved quality of surface tillage of soil.
