An aerator (100) with coring depth adjustment includes a coring depth adjust rod (130) centrally positioned between a left side and a right side of the coring head (114). 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 (144) 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.
