I had skid plates welded to the bottom of my bucket, along the sides and across the back to keep from gouging my driveway and wearing a hole in the back of the bucket. Sure would like a replaceable cutting edge, though, as mine is welded on....
This is a front view of the bucket. I did not play with the bucket to reduce the gap between the ground and the bucket when I took the picture, the gap is about 1/2-3/4" But with the fel tilted it is less then an 1/8". The more I tilt the bucket the less gap at the bottom.
