FIG. 1 is a top, left, rear perspective view of a tillage sweep, showing my new design;

FIG. 3 is a rear bottom perspective view thereof;

FIG. 4 is a front elevational view thereof;

FIG. 5 is a rear elevational view thereof;

FIG. 6 is a right-side elevational view thereof, a left-side elevational view being a mirror image thereof;

FIG. 7 is a top plan view thereof; and,
