I am trying to bring my lawn back to a pristine state after many years of gardeners who just do the basics, cut the grass and leave. So I'm educating myself as to how to maintain the lawn, besides fertilizer and watering correctly. I was having more run off of the water than I liked rather then penetrating the soil and roots. A friend looked over my lawn and showed me how much dead matter that won't decompose actually is sitting on top of the soil, but hidden by the grass. He then explained the need for thatching. There are alternatives other than this rake, but they are very heavy and expensive equipment. The first pass I made on a small 3'x5' patch of lawn brought up a large mound of dead brown dead grass and weeds, I was amazed. The first time you use this rake it is a bit on the hard work side, but afterwords on follow ups like prior to fertilizing it is much easier since the years of accumulation are gone. Use this rake right after cutting the lawn and you will find you aren't tangling up and pulling out some of the good grass too often. My run off problem disappeared and the lawn is much healthier. This rake is very sturdy, made well and works as described.
