Took delivery of a new 2013 X738 and love every part of it. Auto connect 54" HC mower deck, Auto connect snow blower. They both go on very easy. All of the other features are great and perform well. The only thing that annoys me is the fan belt. When you first start it and about until 10 min. later the belt squeals. The belt is tight and I have spoke to others who have the same problem on tractors and gators. Question is : Anybody else had this prob. and how did you cure it ? Dealer says this is common on many J.D. products and goes away with time.
