The L6060 has a LA1055 loader has a factory HD bucket and when carring a bucket of dirt the loader arms drop from 5' to ground in 1.5 min. and bucket rolls about 1/3 the way in same time.
It is Back at the dealer now, but they have offered nothing to date as to cause or fix. Not sure they know the cause. Everything is electro-hydraulic and new technology. Wondering if anyone had expierenced a similar problem.
The cause is clear - hydraulic leakage.
The boom dropping is likely spool leakage in the loader valve. Spool leakage is a normal fact of life in all valves but 5' in 90 seconds is excessive. The dealer may try to tell you differently.
The bucket sag is more complicated. It could be due to leaking piston seals in one or both cylinders abd/or spool leakage in the valve. If its spool leakage its excessive. If its leaking seals its defective. You can easily test the seals by loading the bucket and the disconnecting both of the bucket quick connects. If the bucket sags the seals are leaking. If it holds the spools in the valve are leaking.
I will also note that the loader valve may be auto leveling. That can make diagnosus more complicated. If you hsve an auto leveling vvalve and csn disable that feature it will simplify diagnosis.
EDIT: My money is on a decective loader valve. Dealer msy not be happy with that idea.
