Anything binding on the loader Grease it up. Also jsut had an issue with using aftermarket filters on a ford van MAybe filter is restricing flow?

Try disconnecting the quick disconnects and reconnecting them. One might be partially closed and restricting the flow.

Reading the after market filter post made me think of my neighbors hydraulic issue a few months back. He changed the fluid and filter, and with similiar results. When he opened the packaging for the filter, the gasket was loose, so he just put it just inside the rim, which it fit, and finished the job. When he couldn't figure it out, he called me over and we discovered the gasket was not supposed to fit just inside the rim, but on top of the rim in a groove in the housing. While sitting in the rim it mostly covered the outer holes of the filter restricting the flow of the hydraulic oil. Real easy mistake to make. I hope you solve it and please post back what you find. You never know who it may help. Good luck!

I notice there has been no mention of boom speed compared to bucket speed, the valve supplies two different hydraulic circuits. Does the boom seem slow or just the bucket?

Pull the boot up on the control valve so you see the linkages, check the movement of the valve spools.

You mentioned pressure ..how was this checked? Most systems in good condition will develop full pressure at or near an idle ..this is a quick way to check system health. Recheck your filter to see if there is a gasket leak (or did the problem develop before the filter was changed?)

I have seen the bolt that holds the rod piston back out on the Kubota loader, both in the boom and bucket cylinders. Oil can bypass the seals when this happens. This usually only affects one function of the loader (boom - bucket)

Your pump supplies both the loader and 3pt hitch ..is it also slow? >>Which leads to the next question, What did the oil look like and was the filter plugged? >> oil nasty + filter plugged + hydraulics slow = fried pump ..just a thought.
