Looking for a little help and advice. A neighbor has a 48" Exmark CT, 18 hp Kolher with roughly 60 hrs on it. He is planning on selling it and he told me to make him an offer. What would be a fair price? Mower is well maintained. Second, if I buy this mower I will want to add a mulching kit. Will I have any problem mulching with the 18 hp engine.
