Soil surface tillage point in combination of primary tillage shank system

In a primary tillage shank system having a wheeled main frame adapted to be towed through a field by a towing vehicle, said main frame having a front end, an opposing rear end and opposing first and second sides extending therebetween, the improvement comprising:

• a plurality of similar working units supported by said main frame at generally equal intervals between said first and second sides, each said working unit having a working line along which it works the soil generally in a straight line in a direction generally parallel to the direction of travel of the system during use such that each said working unit works the soil and prepares a seedbed in a strip, and together the said plurality of working units prepare a plurality of generally parallel continuous seedbeds in the direction of travel of said tillage system;
• said working units each comprising a series of in-line ground-working apparatus including, in a line generally along the respective said working line, a surface soil tillage point to create loose soil, part the residue, and create small clod sizes of soil in front of the trailing tillage shank path, and a tillage shank to fracture and further loosen the soil.
