WORKING ELEMENT FOR DEEP LOOSENING OF SOIL Russian patent published in 2014 - IPC A01B13/08 

FIELD: agriculture.

SUBSTANCE: working element for deep loosening of soil comprises a rack with a chisel. The rack has a width of 2.2-2.6 times less than the chisel width. On the side surface of the upper part of the rack the through mounting holes and the adjusting holes are made, located on the same vertical axis.
