Yesterday was not good for me. I was greeted with a flat tire on the LA120 when opening the garage door and found a nail causing the problem. Not having time to patch it, I blew it up and started mowing around the house and did the ditch. After a short hour, the tire needed more air but I parked it and started the 2320 to mow the big stuff. Well, after about 1/2 hour strange sounds started coming from the deck with a bit of a vibration and then BANG, the belt took off landing if front of the tractor. Not sure why the belt broke since the deck has may be 30-40 hours on it. No cut marks or rubs are shown. Anyone else had trouble with belts breaking with a small number of hours on them? The JD dealer said the belt will be in this Wed and will cost $71.. I asked about warranty and gave them all a good laugh. Now I need to plug the leak in the other tire. What next???
