i was wondering if you could tell me what my problem is with my 520 power-trol when i lift my swather and it keeps lowering before i am positioned for a new round.i have to keep raising it to get turned around.my 520 is a later model.it just started this this summer.would it probably be bad o rings or do i have to remove the power-trol the fluid stays up in the power-trol.
thank-you in advance for your help. terry
