Another option might be to check with country machinery (see the post up top for contact info) and send your rollers to them to have new rubber put on.   My picker goes over a lot of acres a year due to my volume of ear corn sales so I prefer to put new parts on or have stuff rebuilt to like new whenever possible instead of dealing with someone else's half worn out used parts.  However, everybody's situation and budget is different, so whatever works best for you. 

Well I ended up ordering the rubber shucker rings from Country Machinery. They don't charge a lot for rebuilding the rolls but by the time they are shipped both ways it starts getting a little pricey. I opted to do the job myself . It took a little while but finally came up with a simple way to remove the old and replace with new. Only two more to go!
