Before I screw something up, should I put the grinder to my mulching blades? I grinded my old bosses blades, side shute, now I'm starting my own business and am wondering if it will screw up anything by sharpening mulching blades. My wife says my biggest problem is I'm always trying to improve things, even if it's brand new, and even though I'm right in the fixes 90% of the time. More silly questions coming soon. Stay tuned.
