on the dragging. Cleaned up many of then this way. Just don't attach anything to them. Let it drag straight, otherwise the links that are tied to what you are dragging will wear down and weaken the chain. Some people soak them in oil afterward but really you can't handle them after that. Well, not without gloves. A old milk crate is the best thing to store them in that I have found.
throw them in the cement mixer with some gravel.... Turn up the radio..Be careful about dragging the chain behind a lawn mower with the blade operating. Guy I know was mowing grass, there was a chain in the yard that got caught in the mower which was jerked into the blade and was slung around, hitting the guy in the lower leg. Cracked bones, great pain.

, the guy must not back up/turn much?
