Thank you. That was my line of thinking as well. The Edge Tamers are designed to keep the bucket from digging in. With them installed, the bucket rides about 3/4 inch above the ground. For moving snow or a pile of something, that keeps the bucket from destroying the yard. But you can only level with the back edge of the bucket and you cannot easily dig below ground level. Since both the Edge Tamers and the PTB are easy and quick to install and remove, I think they may be good complementary additions that can be alternated when needed.
