Rip strip primary tillage system

摘要

An agricultural tillage implement is disclosed employing a series of apparatus to perform one-pass primary tillage. A coulter is the first apparatus that works the field. These coulters cut, size and part the residue without mixing it into the seedbed. Next, a tillage shank runs a point through the compaction layer to fracture and loosen the soil, providing proper soil aggregate size and air pore space relationship throughout the shank tillage profile. Next is a pair of soil-gathering blades that capture and gather the loose soil and residue together and to create a berm of a mixture of soil and residue. The last apparatus to work the field is a rotary reel that conditions the strip of soil to give ideal seed-to-soil contact and uniform berm size.
