I love the Mow Aerator. I am able to lay the tracks out and drive my riding lawn mower on them and fasten them. I used them all season and my lawn has improved tremendously. I do have to remember that I am not able to drive up on the driveway because you can bend the spikes, but beyond that these work GREAT! Well worth the price and you can use them every time you mow and keep using them every season to keep improving your lawn.
