Does your 3 point work? If you have quick connects look at them real close. They can cause this problem. If your 3 point doesn't work, loader doesn't work, next is pump problems (sheared key, bad pump, etc.). Follow high pressure line from pump and loosen fitting to see if any pressure. Go from there.

I went back out and tried a few times over the next hour, and there was no change. The I waited about 2 hours intill everthing cooled down, when I started the tractor everthing jumped and all was fine.


Is ther something that might of heated up that could cause loss of hydralic power?

You might need to clean the pickup screen.

I went on Hoyte site and found a diagram of the screen. Looks eazy enuff to clean. My question do I need to releave pressure. How much oil will drian out at this level.

Pretty much all of it will drain out. My 2002 holds 4 gallons so I'm guessing yours may hold around 5 but don't really know. No pressure where the screen or drain plugs are.
