Im looking to buy another mower this season. Im not sure if i want to spring for a brand new mower, because of brand new mower prices. So im looking to buy a used one at the auction at the dealer by my house. What type of things should i look out for. What are the expensive things to fix (that are likly to go wrong with mowers), and what are your thoughts on used mowers that you don't really know the history on?
