It turned out to be a frozen spindle. with only 18.3 hours of use on the machine I figured john Deere owed me a new one. I called the shop where we bought it and they agreed and gave me a new one. The book said to grease them after 50 hours of use but I dont think any grease was in it when we bought it. I made sure the new one had grease and hopefully it will last a long time. These spindles look different then any others I've seen and I'm not sure they can be rebuilt. I just hope its a hell of a long time before I really need to know.
