Each aerator mechanism comprises a link member which supports a pivotable tine holder having at least one tine, a stop member attached to the link member for contacting the tine holder and maintaining a minimum predetermined angle between the tine holder and the link member; a means for adjusting the predetermined angle between the tine holder and the link member; an elastomeric band pivotally connected between the frame and the tine holder for urging the tine holder against the stop member; a drive link attached to the drive shaft; and a connecting rod pivotally attached between the drive link and the link member.
