An agricultural tillage implement has a main frame with a plurality of ground support wheels, and a finishing attachment arranged behind a group of primary seedbed preparation tools. The finishing attachment includes a reel assembly having an over-frame tube to which reel standards are attached, and reel arms that connect the over-frame tube to the implement frame. The reel arms are attached to the over-frame tube by a flex pivoting connection that allows at least one degree of freedom movement when the reel encounters an obstruction. The reel assembly includes a rolling reel basket having slats made from half-round material. The slats are oriented with leading edges that provide clod breakage and residue pinning action during their descent, and rounded surfaces for firming soil at their lowest quadrant position. A push configuration treader assembly with multiple operation modes can be mounted compactly close to and ahead of the reel assembly.
