Well I bought it with about 6 on it from dealer. It was a demo. Assumed they did it. I just changed the oil now. I put a new hour meter on it because the other one broke. They only had a Scag one. It works tho. I'm running Rotella synthetic blend 10w 30. To me it sounds like one of the rollers on the deck is rubbing but that's not it. Mine has I would say 16 hours on it. Just turned 10 hours on the new meter. I look every bolt is fine. No grease fittings besides the spindles that I can see. And its squeaking. The chain hung deck might be moving? I have no clue. I could have spend a little more money and got a better mower. But I thought buying ferris they would be very well built even being low end commercial. I like it for the price. If I could have spent more I would have and bought a exmark Lazar z or walker.
