Hissing coming from loader

[Fallon]

Mine drops fast, but not disturbingly so. I have no qualms about dropping my loader in float from any height. Quite probably a restrictor in there on the float circuit.

When my hydraulic oil filter needs changing, I hear it using the fel. When I change the filter, everything is quiet. Might check that out,

It's done that since day one. I've got 130ish hours on it now & it was doing it just after my 50 hour filter change. Pretty sure that's just Kubota thing, & it's only in float when dropping somewhat fast, not when being powered up or down.
