good luck. I've been wrestling with my tiller for three years. this was a low end rear tine tiller made by Ardisam, sold under the Scott's name at Home Depot, I think. I bought it 20 years ago, did absofuckinglutely nothing to it besides put gas and oil in it for 17 years, so I shouldn't complain about one serious tune up two years ago, forward and reverse drive belts last spring, and now the reverse drive belt again today. have really gotten my money's worth out of it, and haven't taken care of it at all, lol.
