I am currently in search of a 48 walk behind. I'm looking to upgrade from my 36in. walk behind. I am interested in trading to settle any price difference if it is a possibility. My mower is a 32in snapper. I replaced all the belts and the engine last June (so about 100 hrs.) I replaced the gear box 2 weeks ago. In all I have about $1,000 in upgrades. I do not think there is anything major on this mower that can break because I have replaced and upgraded all the major components.
