Has any 990 owner been contacted by their dealership latey in regards to some "product improvement" that has to do with a friction washer or some such thing? I am curious because that is what is happening to me. I got a phone call from the dealership saying that they were coming to replace/repair my tractor, and the woman said that is was a product improvment. I had no idea as to what she was talking about (I don't think that she did either!)
