I have a hydraulic problem, the loader won't work and 3pt. won't go up, heard a high pitch sound while mowing with a brush hog. I can't find anything on taking the pump out, not sure where it is, I think under the seat, no leaks anywhere. Looks like I have to take everything off the rear to get to hydraulics?

Likely you have a hydraulic quick coupler become unseated.

From memory, your tractor normally has a backhoe.

The hydraulic flow goes to the backhoe valve and then, using a power beyond port, back to the rest of the tractor including the loader.

Do you have a hose loop which you connect when the hoe is off?

That would be the fist place I would disconnect and reconnect any couplers.

Do NOT go removing hardware as you will just make a small problem much bigger

The pump is in the transmission so you will not be able to get to it.
And like Dave said check the rear loop.
With the engine off, move the loader lever up/down/l/r to release any pressure.
Disconnect the loop and reseat it.
Otherwise it is on top of the transmission.

High pitch sound is usually a deadheading pump.

The hydraulic pump is actually mounted on the transaxle housing right above the Left-Hand rear axle housing.

Thanks Dave! I will check out the hose loop in the rear, took the loader off.

The high pitched noise and now no noise has me wondering what's really going on.
