Sumo trio

[Bobthebuilder]

Having an issue with our 3m trailed trio, when kicking the legs back on the hydraulics after a few mins they all drop back down by themselves, no signs of any oil leaking anywhere, happens on more than 1 tractor so not a tractor problem, even happens when taken off the tractor almost to the point that there’s actually pressure on the legs on the ground when hitching back up again, any ideas? Pressure accumulators/valve block ???

Could be one or more ram seal leaking internally ?
