Had a friend of ours at my wife's work today ask if we had an edger, but I pulled the engine off it this summer to fix up an old mini-bike someone gave me. When I found out that he was trying to bury invisible fence wire on his new home without a lawn, I offered the 502 and my plow. it took an hour to trench around his whole property, shy of the one edge of his yard that took him 5 hours with a shovel! win for the WH!
