Thinking about changing the belt routing on my walkbehind edger to make the blade spin backwards. The only time I use my walkbehind is for new clients to get a good edge / small trench so I can maintain with my edge-it. When doing new clients I usually walk backwards to dig the durt out so my edge-it works like it should. Just wanted to see if anyone has tried this. I was thinking of useing two 8-point edger blades (.200 thick) running the blade backward to dig out the dirt. Obviously you would have to go slow, but what does everyone think?
