Product comes with hard to use head. I bought this item to replace my Ryobi string trimmer. I attached the Ryobi string head, or an Expandit metal brush cutting blade setup. Both make this unit more useful. Expandit accessories for quick connect shafts are available at Home Depot. I also changed the head to a uiversal quick load head made by Echo(also available from Home Depor), and then use .155 string (thickest available). Now I have an extremely powerful electric trimmer, ready for hard work. Great , powerful unit.
