NH 6610S Hydraulics

[kbright]

Bought tractor back in November. Needed service bad changed hydraulic fluid and filter. Just hooked it to 10 foot bushog - Lift will not pick it up. Did pick it up twice after much trying but that was it. Will pick up light equipment. Transmission mounted single pump. Operators transmission, rear end, power steering, all. Pump lines go to power steering first. Suggestions? Thanks

Just various thoughts- can you check with the prior owner to see if they had any lift issues? Hydraulic fluid full? No whining or other odd noises (relief valve?) when trying to lift? Nothing physical blocking the lift? Any 3pt adjustment knobs that may be causing the weakness (ie: might be just an adjustment?)?

If you have a loader, can you lift the mower at all with that?
