ABSTRACT:
A cultivator sweep includes a body with a forward point and wings diverging outwardly in the rearward direction. In one embodiment, a row side sweep includes a row side wing angled upwardly from the horizontal at an angle of approximately 27 degrees, and the opposite wing is angled downwardly, to closely match the profile of the ground from the row bed to the row middle. In another embodiment of the invention, a wide sweep extends between the beds of adjacent rows and includes wings with outermost portions bent upwardly at an angle with respect to the horizontal to provide a sweep profile which closely approximates the ground profile between the rows for more uniform depth of penetration, less soil throw and crop root damage, and reduced draft. The sweep configuration, wherein a fore-and-aft extending line connecting a point anywhere on the leading edge of a sweep wing with a corresponding point on the trailing edge of the wing lies at a substantially constant angle relative to a horizontal plane, provides constant soil lift regardless of soil contact point along the leading edge. The sweep configuration therefore provides soil flow characteristics similar to those of a conventional flat sweep.
