I had never even heard of the edgit disc until i started at work this year. I used to mow for myself with just a regular ryobi string trimmer. From doing this sometimes i would take dirt off so the edge of the yard is pulling back away from the curb a good 2-4 inches. I wanna take it back out but the problem is my yard is 3 inches higher than the curb...so if i put dirt on there it'll just wash down the side with the next big rain. What else is there?
