Abstract
An agricultural tillage implement that employs multiple apparatus to carry out a strip-till farming operation is disclosed. A tillage shank runs a point through the compaction layer to fracture and loosen the soil, forcing it upwardly and outwardly where a pair of angled soil-gathering blades, located adjacent the shank, redirect the soil into a newly created berm. A trailing conditioning rotary reel having a particular cross-sectional profile forms the soil into a uniform raised berm ideally suited for planting.
