might be worth looking for a ariens mower if you are shopping used. i haven't seen a rotten one yet so i would assume the steel they use is better quality. just make sure to avoid self propel. parts are expensive. got one here that needs a $60 belt. avoid honda's with the steel decks. the engines are good but seem to see a lot with rotten decks so i would assume they use junk steel for the decks. the mtds are ok but i think they are effected by how you maintain/store them since they usually start rusting from 1 spot and it just spread from there.
