Kubota B7800 hydrolics sound like it's cavatating.

I have no power steering, weak and Shakey loader, and 3 point. Also low power in low won't even go on high. Is it my pump or could it be something else?

I would perform the simple things first before condemning a pump.

1) have you verified system is full of oil?
2) when was light time filters were changed?
3) Has suction screen been cleaned? I believe that tractor has one but not not positive.
4) If rubber hose on pump inlet check for cracks in the hose. Also check if any clamps are lose.

Items 1 - 3 are mostly suspects.
Other possibility depending on location and temps is water is system has frozen blocking suction screen.

Check for air in the system.

I mean I read a lot of Tom Clancy novels and when your submarine is cavitating, it makes noise that can be detected by enemy destroyers.
