'My Black&Decker electric mower was loan to friend. He ran the mower
over several boulders several times, chipping a couple pearl size
sections off the blade. Possibly, this is causing the mover to vibrate
to the point of causing a shoulder sore.
I remove the blade, then clamp it to a vise grip. I have an angle
grinder that I will use to fix the balancing problem. The problem is,
I've never done this before. What is a practical way to balance a mower
ME: The crankshaft has been damaged. Its not the blade. The mower is
now history. See if your friend will go halves on another mower.
