I thought it was due to old belt so I replaced it but it came off in the first hour. Any ideas?

Check for a bad spindle bearing..

Just saying "came off" doesn't explain much but I'd guess bad bearing.
Assume no damage has happened to the deck, and no mis-aligned belt sheaves.

Everything seems to be in place. Nothing appears to be damaged. It just pops off while I'm mowing. How would I know if I have a bad spindle bearing? Which spindle would I check?

So, it appears to be the idler (JD Part #AM106627) that has gone bad. Thanks for the input beenthere!
