If this not the correct forum for this thread, then please advice. I need to get longer life out of my bagger blades if possible. They are heavy duty/high lift blades on my Kubota 40" lawn tractor. The blades are only about ten years old, and they still have good mass, even though I keep the blades so sharp that leather gloves and extreme caution must be used to R&R the blades.The wear rendering them useless however, is at the blade tips, but not the leading edges. They are paper thin where the lift angle, or bend, is. Does someone out there know anything about ultra-hard powder coating mower blades? I just hate to toss the blades as they still have usable leading edge material. I understand that the coating would go away from the cutting edge as it is sharpened, but coating might significantly reduce wear at the bend.
