The harrow is very good and deserves 5 stars if it weren't for a tangling problem, not during use, but when the product was first received and when storing it.
The harrow works well, but we had to make some modifications because it had a tendency for the back corners to flip back over and get hooked up. We added a bar on each side so that the harrow will hold its shape. Now it stays in contact with the ground and does a great job.
