did that and it does the same thing. Inspected my connections and still the same.Sounds like one of the Aux stems sticking. Pull both stems and inspect, if you do not notice anything obvious swap stem from left to right and see what happens.
What is low on power? Auxiliary, all hydraulics, or engine power? If the front couplers are fitted into a manifold style block its possible the male coupler on the machine is leaking internally to case drain. Is the rod end of the grapple plumbed to the male coupler? Only other thing I can see is the aux load check but the aux check has an orifice anyways so probably not that. Is this machine AHC, (Advanced Hand Controls).did that and it does the same thing. Inspected my connections and still the same.
Maybe the aux control switch is staying slightly engaged or still allowing power to continue through to the aux hyd solenoids. maybe try unplugging both solenoids & Then operating the machine. If the power is restored, then you will know it is an auxiliary hydraulic issue. Hope that helps you out some.What is low on power? Auxiliary, all hydraulics, or engine power?
