Hi all.... I have a problem with my 3PH lift... with an implement on it you can raise it just fine but then it drops a bit and starts "cycling"... raise, lower, raise,lower.....etc. Shut the tractor off and it drops. FEL is working just fine, just the 3PH is giving me issues. It has about 2200 psi on the guage at the FEL and you can watch it up and drop while the 3PH is doing its thing.... Any Thoughts? Is this just an adjustment or do I need to tear into the control valve?
