Thatch layer is a build up of dead plant material, moss and grass clippings which combined prevent water, nutrients and oxygen from reaching the root zone. Using this scarifier will encourage a healthy lawn. The scarifying and aerator drums are interchangable and a T spanner is included for an easy change. This machine also includes four position height adjustment and a foldaway handle for comfort and easy storage.
