I agree with Bird and the dealer. Since it wasn't a defect, it's not covered under warranty.
A personal experience..
Within a few hours of taking delivery of my TC25D with a 60 inch mmm, I broke the front right caster wheel off the deck. As I was approaching our sidewalk, the front right of the deck dropped slightly (into some mulch in the flower bed which adjoins the sidewalk), the caster wheel swung from being parallel to the direction of travel to perpendicular causing the caster wheel to catch on the sidewalk instead of riding up and over it. As I drove forward (noticing none of this) the shaft the caster wheel was attached to broke. I only discovered this as I made my second pass over the sidewalk and noticed something laying in the flower bed. "What the heck is...oh crap!". The caster wheel and part of the shaft was laying there, the rest of the shaft was still in the deck.
The next day I called the dealer to see if they had the shaft in stock. They did, cost about $25 (I think). I asked them to reserve one for me and I'd be over to pick it up. I drove to the dealer, showed the guy behind the parts counter the two pieces to make sure the part they reserved was the right one. As he compared the new shaft with the two pieces I brought in, I told him what happened. He looked at the two pieces of the broken shaft and said, "This shouldn't have happened." He then took everything back to the shop where they installed the new shaft, greased it and gave it back to me at no charge. I fully considered this my fault and no way a defect with the shaft but I wasn't going to argue with him. /w3tcompact/icons/laugh.gif
Perhaps this is an example of the difference between a good dealer and a great one?
