I've got a rayco 1665AC stump grinder. I hate the lexan shield. There is a static charge that makes dust stick to it fast. It glares when the sun is just right. I'm thinking of replacing it with small hole expanded steel I realize that a small partical may slip through if it hits it just right but it should stop anything that can hurt,(I wear face protection) I guess I feel it's still safer than having my head around the side of the shield to see what I'm doing. Anyone else done this?
