Sounds like you are getting the run around treatment. They will just continue to ignore you and pretend no problem exists until your warranty is up. Then they will suddenly be willing to work on your tractor for $60.00/hr plus parts! My daughter had a similar problem with her $32,000 new Madza CX-7. Problems with the transmission. Every time she took the car in to be fixed, they said nothing was wrong. When she showed them how the transmission slipped, they said it was within specs! Sometimes you run into dealers that have no pride in their product or work. Unfortunately, thats when lawyers come in handy. Whatever you do, first try to get the area rep involved and if that doesn't work, get a lawyer before your warranty is up! I can't see how there could be another side to this story, since you bought a new tractor, its hard to imagine how the defective engine could be explained away and justified by another "side" of the story.
