Went out to use my new JD X354 to cut a very long lawn after all the rain we have had and guess what? 14.5 hours of use and the drive belt for the deck was off and totally jammed under one of the pulleys. I was fine last time I used it. I tried to get the pulley off to get the belt out but no luck. The nuts were so tight I could not budge them. JD dealer coming tomorrow. That's good service for this time of year. The must be very busy but it is a new tractor I purchased from them.
