Single angled blade coulter and fertilizer opener

摘要

A conservation tillage attachment for a seed planting unit that functions to cut and clear away prior crop residue, fracture the soil ahead of the seed trench opener, and form a trench for the deposit of dry or liquid fertilizer offset from and parallel to the later formed seed trench. The attachment includes a single disk blade disposed forward of the seed trench forming unit. The single disk blade is disposed at an angle of approximately 5° from the line defining the direction of travel of the seed planting implement. The attachment includes a selectively adjustable down force structure and a selectively adjustable depth control mechanism.
