When I use the auxillary valve on my 630 the Eagle Hitch arms slowly lower. The arms stay up any other time, even when the tractor is not running. Any ideas?

I have a loader on this tractor with a 5' manure bucket. It seems really slow and always has. I don't know what normal is nor how to measure flow or pressure of the system. The 3ph works fine except that it drops while using the auxillary valve.

I agree with Loren...It sounds like a mechanical (valve) issue. If you need to start checking the hydraulics. The system specs are 9 gal/m and 1300-1500 psi

Do you have a diverter valve to supply oil flow to loader, and nutralize the 3pt. They are hard to move back and forth and the spool can rust if left with the knob pulled back out exposing the spool. If you have this setup spend some time freeing the spool so it obtains full travel. Also the two levers in front of the stacked valves share a common shaft axis, one inside the other. They may be binding and when you move one, lever the other also moves. (on the same note are the levers beside the seat free on the sholder bolt that supports them, or is the bolt turning and moving both linkages). These are all mechanical issues and should be checked first. Address hyd leakage issues secondly.
