METHOD FOR BOARDLESS PLOWING OF SOD MINERAL SOILS AND DEVICE FOR ITS REALISATION Russian patent published in 2011 - IPC A01B79/00 A01B49/02 

FIELD: agriculture.

SUBSTANCE: method includes boardless and further active tillage of soil. Tillage is carried out with alternation of passive and active zones. Width of tillage zones is established as not more than 30 cm with ratio of depth of passive tillage depth h to width of zones b and to feed at one cog of active tillage S, equal to h:b:S=0.7…1.0:1.0:1.0…1.4. Depth of active tillage is established as more than depth of the passive one by value of longitudinal ridge h_l of active tillage. Vegetation remains are removed from the middle of active and passive zones to the sides of their borders by 80…100 mm. Device comprises a frame, a power train, passive working elements and rotor arranged behind them with active working elements. Passive and active working elements are arranged in the form of chisel hoes and chisel teeth accordingly. Chisel hoes and teeth are arranged on frame in staggered order and are equipped with smoothly bent cylindrical bars with diametre equal to thickness of a chisel hoe. Ends of bars are distanced from planes of symmetry of working element stands by 80…100 mm.

EFFECT: technology and structural design will make it possible to improve quality of treatment of sod soils containing large quantity of vegetation remains.
