Yes. It could be the drive belt or the rivots that hold the clutch together could be getting ready to shear off. Toro had problems with these clutches and have since went with a different manufacturer. I would change the belt first and it might save you 3k when the clutch breaks in two pieces. A worn out belt puts added stress on your clutch. We change ours out twice a year as a proactive approach. Belt is $85.00. Don't wait, your next noise will be costly.
