Benefits of technology

[0015]The field cultivator sweep of the present invention includes opposite left and right wings which extend outwardly and rearedly from a center line so as to form a symmetrical body with a V-shaped leading edge. An upstanding neck is provided on the body for mounting to sweep to a shank of a cultivator. A soil conditioning element extends downwardly from the bottom of the body. In a preferred embodiment, the conditioning element is a flat blade with a rearwardly angled leading edge. The blade creates a vertical slit in the soil as the sweep is pulled through the ground, thereby minimizing soil compaction and enhancing plant root growth.

Problems solved by technology

However, the sweeps have a tendency to compress the soil beneath the sweep, which makes it difficult for the roots of the crop to grow into or below the compressed soil.

Embodiment Construction

[0032]FIGS. 1-4 show a preferred embodiment of a field cultivator sweep 200 in accordance with the present invention. The field cultivator sweep 200 includes a first wing 210 and second wing 220, together forming a wing body, and an upstanding neck 230 at the rear of the body. The neck 230 is configured to attach to a shank of a cultivator. To this end, the neck 230 may include a plurality of apertures to connect the cultivator sweep 200 to the shank. For example, in FIG. 2 the field cultivator sweep 200 is illustrated as having two apertures 232 and 234 to allow the field cultivator sweep 200 to connect to the shank by a pair of bolts. It is understood the above connecting method is merely exemplary as the field cultivator sweep 200 may be attached to the shank by a different method, for example, by clamps, pins, screws, and welding. Furthermore, the number of apertures illustrated in FIG. 2 is not meant to be a limiting feature since some embodiments of the cultivator sweep 200 ma...

Abstract

The field cultivating sweep includes a body with wings extending from a center line in opposite directions, and a conditioning element extending downwardly from the wing body. The conditioning element may be a blade extending vertically downwardly along the center line of the body and having a leading edge sloped rearedly from front to back. In alternative embodiments, the conditioning element may have a triangular or rectangular shape or may be in the form of a fluted coulter. The conditioning element acts to till the ground vertically and break up compacted soil as the sweep is drawn along the ground.
