4020 Bursting Power Steering hoses

My 4020 keeps bursting power steering hoses. Has anyone had this problem? Is there any pressure adjustments that can be made to lessen the pressure?
 
Is it that little steel line behind the panel at your feet?
If it is, I have the same problem. When one pops we just make a new line. It will last about six mouths and pop another.
If you find out let me know.

DO NOT get the kit that John Deere says will fix it. Dontt waste your money. It has two metal fittings and a rubber line, and two clamps. I put that kit on one of my tractors, and the motor didnt start till the that rubber line was busted.
 
One of the reasons that line fails is the hold down clamps have been left off some where along the line and vibration works on them till they fail..
 
The replacement oil line and hose is more than adequate to handle normal oil flow and pressure from the stering valve case drain. Problem is when this line burst or leaks, steering valve has allot more than normal oil flow and pressure on it due to internal leakage of steering valve seals and orings. Long story short replacing the line is not repairing the problem. Remove and reseal steering valve and the line will no longer be a issue. I have done two of these steering valves in the last three weeks. Pretty common repair on these old tractors.
 
The supply lines that I think you are talking about should never have more than system pressure (2250psi) on them, no matter what goes on in the steer valve. I'm still leaning to vibration being the probable cause for line failure. A lot of times when steer valves are removed these line clamps don't make it back in place..
 
Thanks WTW for the info. I thought excessive pressure was a problem, but didn't know what I needed to do. I knew someone would know what to do. You people sure are helpful. Hope I may be able to repay the help sometime.
 
More 4020 saga, it is leaking hydraulic out of the steering column today. I believe one of the lines is leaking. It is leaking about a gallon an hour, and there are 6 hours left to plant. We are hoping to get done with it.
