The Drake is an innovative solution that combines two professional grooming tools into one. As you pull the drag, the head will open and scarify your soil while the mat grooms your surface to a pristine and professional finish. The Drake comes with the standard flexible steel mat, which is constructed from 3/8" deep x .046" thick crimp with a 1" x 1" mesh. The scarifier head is constructed of heavy-duty aluminum and is more effective at digging than most other lute rakes.
