I have had my snapper lt 16 for about 11 years without much of an issue. This year however I have been chasing repairs all summer. This repair has to do with the idler pulley and the belt tensioner. I have a 41 inch deck and the both are connect using a bracket. The deck has rusted thru and the bracket broke away from the deck. While shopping around for a used deck I found a guy that has an lt12 to pull parts from. The deck was quite a bit smaller than the one i got, but the mechanic assures me the smaller deck is interchangable. So my question is this should I just try to get it welded or change it to smaller deck.
