The present invention relates generally to agricultural tillage equipment and, more specifically, to a vertical tillage sweep providing low surface disturbance. The sweep comprises a wing structure with a downward and generally vertical fin, and having specific wear coating placed on the various wear surfaces.

A blade for use with a grading machine comprises an attachment portion, a working portion including a plurality of teeth, each tooth defining a bore, and a plurality of wear resistant inserts retained in the bores of the teeth.

A subsoil tool for ameliorating soil compaction having a shank attached to a toolbar of a tractor, wings on forward wing links pivotally engaged to the shank, and following wings on a wing rod pivotally engaged with the forward wing link. The forward wing links are positioned near the bottom of the shank in front of the rear of the shank. The wing rod is positioned behind the shank. A drive box having a hydraulic cylinder is engaged to the toolbar and pivotally engaged with the wing rod. In use, a portion of the subsoil tool may be inserted below a surface of the soil, the height of the subsoil tool may be adjusted, the subsoil tool may be rotated, and the hydraulic cylinder may be cycled to move the forward wings and following wings.

A sweep for cultivating soil in a field, the sweep comprising opposite left and right wings joined at a center line to form a V-shaped symmetrical body with leading edges. The body having a top surface and a bottom surface, with each wing having a wing tip, the wings forming a front nose, with the leading edge of each wing being spaced rearwardly from the nose. The sweep also includes a neck extending upwardly from the center line of the symmetrical body, a tungsten carbide nose plate attached to the body top surface at the front nose, and a pair of leading-edge tungsten carbide edge plates, one of each is attached to a respective wing leading edge.

An agricultural implement has (i) an elongated open channel member; and (ii) a connecting assembly comprising a first vertical connector plate positioned against a first vertical side of the open member and a second vertical connector plate positioned against a second vertical side of the open member. When the open member twists about a longitudinal axis, its upper and lower flanges will move within upper and lower channels about upper and lower raised surface areas. A clamping assembly includes: a first clamping member extending horizontally between the first vertical plate and the second vertical plate positioned over and proximate an upper surface of the upper flange; a second clamping member extending over and proximate a lower surface of the lower flange; and a third clamping member extending (i) over and proximate a lower surface of the lower flange or (ii) over and proximate an upper surface of the upper flange.
