Filters, checked releif valve, checked 2 check valves, all good, was tould to remove fill cap and have someone work 3 point lever, listen an look for fluid movement, i do hear it spraying inside, what should i expect to see once i remove cover?

That your model was made from 2003 - 2007 - so it's at least 16 years old -

The next test I would do is hang an implement on the hitch, rev it up til you can lift it, then turn off the tractor. If my thinking is correct, when you shut it off (the tractor, NOT the lift) that there's a good chance the lift will drop in less than a minute. If so, you'll probably need to find (at least) a replacement seal ring for the (internal) 3ph lift cylinder.

If you don't already have a SERVICE manual you'll probably want one (unless you're filthy rich) it's painful enough to pay today's prices for parts, WITHOUT also paying even MORE for labor - good luck... Steve

Even better - having been one I know it sometimes take a bit for a "newby" to find the best path to the answers they need ... Steve

Thank you, i found problem, in top cover in main valve, the accessory valves had a LOT of brass grindings in return which in turn goes back through main valve, i took valve completely appart and cleaned, repaired problem, thanx for your thoughts

You're welcome - and thanks for the update; seems like well over half of this type post NEVER gets a final update... Steve

Brass is found in the sleeves of piston pumps. You may have a bigger problem soon.

I believe this brass debri came from another piece of equipment, this tractor has had this problem for what i understand, about 5 years, the guy that owned it previously didnt worry about it because it would still pickup what ever was on 3 point, just had to rev throttle, so after i got tractor, i wanted it workin correctly, thank you for your advice

This tractor has 2 cylinders that make 3 point piviot, i thought maybe i had a blown cylinder too but when i took the 2 top lines off and pressured cylinders, i had maybe a very little fluid come thru, not anything under any pressure also once you got 3 point lifted, it would hold load, thank you for your thoughts

"This tractor has 2 cylinders that make 3 point piviot"

If you can SEE the cylinders, those are NOT the one I mentioned - your comment sounds to me like the tractor has hydraulic top link and hydraulic tilt - but the cylinder that actually does the LIFTING is buried inside the housing that's under the seat - it rotates a shaft that connects to the upper arms on either side of the housing.

The GOOD news is that my comments about the "invisible" cylinder's seal ring does NOT appear to be the problem... Steve
