摘要：
An aerator with coring depth adjustment includes a coring depth adjust rod centrally positioned between a left side and a right side of the coring head. A portion of the coring depth adjust rod is threaded to a frame member of the coring head, and a base of the rod abuts a stop on a frame member of the aerator. The coring depth adjust rod rotates to raise and lower the coring head relative to the aerator frame to vary the coring depth.
