6065 White

[bbattist]

I'm having a problem with a 6065 White tractor. When I have the tedder connected on the 3 point hitch in the raised position and travel over a bump it causes the arms to try and raise further making the relief valve to go off and they won't lower. The emplement has to be disconnected and then crack a fitting on the cylinders to allow them to lower to get it working again. I was wandering if anyone has experienced such a problem and how it was resolved.
