Craftsman YT 4000
I went to my sisters house to look at their hydro mower which was making alot of noise when the pedal was released. Found a worn drive belt and a bad plastic idler pulley. What a pile of junk! It has right at 50 hrs on the meter. I can't believe they would use plastic pulleys behind a 24 hp motor. It was covered under warranty but if they replace with plastic again it won't be long before it's broke again. Just commenting on the cheap build quality of mowers these days.
