I have a Cub Cadet Pro X 636. It’s basically brand new - only 52 hours. The past week, after mowing and with the engine off, I’m getting an odd whirring noise from somewhere at the back or behind the engine near the hydros. Has anyone ever encountered this? It happens every 30 seconds. Hour meter shows no errors in the cycle and the battery meter is still good. Video below -the sound starts at the 19 second mark.
