When ever my flail mower gets a vibration, it means some blades have been knocked off. Yesterday I got a vibration. No blades missing. It isn't so bad at times, and is mostly when the mower is up. I can't find anything wrong. The universal is fairly tight in the cups, but there is some up, and down in the universal bearing cross shaft. Will a universal joint with some slop cause a vibration? The shaft is not straight back, but is a fairly good angle. The mower has been in operation for at least 5 years. Never had this problem before. Any thoughts on what other problem may cause a vivration? Stan
