Has anyone ever had an issue with one of these planters not raising/lowering level at all times? I am working with a 2008 JD 1770NT 16 row that consistently will not lower properly. The RH wing always is slow to respond. Have replaced check valves in main hyd block and both sequence valves on the wings. Only change to this planter from new was adding a 600 gallon liquid fert system. TIA
