When I purchased mine, I immediately welded a 1/2 inch by 2 inch piece of flat bar on edge for the entire length in the middle of the curve. It has really helped save that poor blade on many occasions. Although we all think we are going to be careful and ensure our equipment is not abused, the unforseen is called unforseen for a reason. I have hit survey irons, rebar, snagged pipelines and rock that looked like a stone and turned out to be a buried 600 pound boulder. I know it is hard to burn the paint off a brand new piece of equipment, but believe me, you will be glad you did. You may not have the hazards we have, but then you might.
