Though it's upsetting to me.  I bought this tractor from a John Deere dealer with the knowledge and documentation that it had been completely overhaulled, new clutch, PTO, hydraulics, etc. about 40 hours ago by an Agco dealer located nearby.  My local Agco dealer pulled head and sent it to Arnold's Motors and found that the head was planed OK front to back, but was crowned from side to side -- no wonder!  It wasn't really the first Agco dealer's fault, but he wasn't willing to stand anything other than a gasket.  I know, I bought it As-Is, but the first Agco dealer's policy is 1 year or 100 hours.  I was at about 80 hours, but 1 year and 5 or 6 days.  It was no skin off his nose and he wouldn't expect to see me going that far north again for service etc.  Sorry for rambling.  Don't know if I made sense, but.....well.....there it is.
