Do you sharpen your blades or just replace them?
Checked the blades on my I210 today and noticed both edges are wearing at about the same rate. Seems the blade disc switches direction by itself, so flipping them isn’t necessary. That makes sense, but I saw some owners sharpen theirs every month, while others just replace them when the mower starts leaving rough cuts
Is sharpening them worthwhile, or how often do you change yours?
