This has nothing to do with the problem you asked about but . . what kind of shape is your drive-
disk in? Mine rattles a lot and I looked to see what a new one cost. I was in shock! Mine will stay until it goes - or maybe I'll go first.
The one-piece spring-loaded drive-disks used in 1010s and early 350s were a much better set-up that the convoluted mess Deere changed over to up through the C series. It resulted in many siezed engines and dead crawlers.
