    Loader is plumbed to the main hydraulics (I have two remotes behind the seat ). Thanks for the link JJ. Meant to answer a previous question...loader operates through It's complete range just not with any serious weight (round bale).

    yep, kidding yourself........having to rev to get enough pressure is an indication of a bad/worn pump......the milky fluid is doing it's damage internally to all components......better do your housekeeping thoroughly (clean, change oil and filter and repeat)

    you need to flow test it before doing anything else......sorry

    You could have a multitude or problems.

    Worn pump

    Worn loader spools

    Debris in relief valve

    Worn loader cyl seals

    Contaminated fluid

    Recommendations would be to flush the hyd well.

    Install a hyd gage and do some testing.

    Check relief valve settings.

    Do or have someone do a hyd flow test.

    The reason I think the pump is still ok is because the guy a bought from said he used it to dig a hole just two months ago without issue. Anyhow, thanks for the help guys...I am going to (as recommended) flush it again and pressure test when I get a guage. Merry Christmas

    One more thing...worst case scenario...bad hyd pump. I can get a rebuilt for @$600. Can I replace it myself or is it a dealer only deal with special tools?

    I would think a worse case senario would not be just the pump......it would rather be internally rusted control valves and barrels inside the cylinders too

    That milky hyd oil does lots of damage over time, it makes rust which contaminates everything floating around

    I don't think internal rust and corrosion is the issue. When I pulled the spool valve it moved freely and was clean as a whistle. Same with the other valve just behind it also, when I bleed my hyd lines nothing but clear (milky) fliud came out

    Can you hear your relief valve activating?

    If you install a hyd gage in the hyd system, you will see that sometimes it takes very little pressure to do a job.

    When you fully extend or retract your cyl, do you hear the relief valve squeal?

    If your pump is working at specs, you will know if cyl or spools are leaking. The cyl and or hyd motors is what develops hyd pressure. Any blockage will also develop pressure.

    Look at your hyd pump and see if you can unbolt it from the tractor. If so, then you can remove and replace it, saving you shop labor.

    You need to know the relief valve setting.

    Didn't you say you had to rev it up to pick it your round bales..??

    If your pump WAS good, it would lift it up at idle....it would work slower but it would work....

    Not suggesting the milky watery fluid is your immediate problem......rather I am saying the milky watery fluid eventually leads to component failure, which you have now

    And you don't know how long the oil has looked like this, right?

    Even after you find your immediate problem, the water (sometimes air entrainment looks milky too......from bad pump or suction hose) needs to be addressed too
