Well in 80 hours I have manged to break 7 belt idler springs. Dealer has come out and put new one on each time. Have new blades, checked belt for any flat spots or wear. All is good. Still manged to break another one yesterday. Everytime spring breaks right where hook is that attaches to the bolt on deck. A good friend of mine was there when it broke and he said right away. They have bolt which holds washers down and where spring hook attaches as tight as it will go. This is putting to much pressure on spring and why it is vibrating like crazy a snapping. He said loosen bolt a bit. Put some grease on the bolt where spring attaches and it should be fine. Sound feasible because I am running out of options. Thanks!
