I would absolutely save that pulley. I do a lot of repairs on the fly for myself and neighbors. I live a ways out out of town so running to grab a part really quick isn't a thing here.
The belt only runs these two pullies and the transaxle. With the clutch in, spin these pullies and see if they are noisy, check the condition of the belt, then spin the transaxle pully. I hope it's something simple and easy.
I get lots of questions related to parts for lawn tractors, so I took the time and made a video all about how to find parts and how to save $ buying parts. This video will post to my channel on December 3rd at 6 am West Coast Time
@@GlennsSpeedShop Super cool, thanks! Turns out the parts manual was easy to find and a little Googlefoo got me what I needed on Amazon for about 20 bucks each.
