I have a new to me 2015 Kubota MX5800 with LA1065 front loader. It has 3rd function and the quick couplers for it are seeping out the end. As I was raising a shoot house up (900lbs approximately) in about 20 or 30 seconds at 2k rpms it tilts down and continues to do so. So my question is with the couplers dripping is that allowing it to bleed off that fast or do I need to test cylinders for repack or god forbid a valve replacement? TIA
