Backhoe fell over and died.

It sounds like either you are getting nothing out of the power beyond circuit, OR, if you are, something on the hoe is letting it all bypass right back to the tractor.

As someone else mentioned, can you pull the loop of hose and hear anything change in the tractor's sound? That would indicate that it's dead headed with pressure and would indicate that there's flow available.

Another way, I guess, would be to measure the temperature of the loop of hose when the machine is cold, run it for 10 minutes, and measure the temp of the hose again. If it's significantly warmer, you know there's fluid going through it.

When you don't have the hoe on does the loader work correctly?
Is your setup one of the ones that you have to connect a bypass loop when you do not have the hoe on?
When you attempted to connect to the hoses was your loader still functional?
I am assuming that the two hoses you hooked up to from the hoe did not go to the same fittings as your bypass line does.

Do you have a pressure feed at the rear of your tractor?
There was a discussion recently were the tractor had 3 fittings at the rear,
a power (pressure feed),
a return to tank,
and a power beyond.

That hoe hooked up to the power (pressure feed) and the return to tank,
with the hoe removed the bypass line went from pressure to power beyond to power the 3 point.

Yup, that was mine, glad we finally got that figured out!

It looks like the boom is fully swung to the side. Probably settled that way when it fell over. I don’t know enough about hydraulics to know if that is creating a problem. I know if I take my loader off in the sun it gets pressure in the lines and makes it hard to hook up. Are the lines for the back hoe hooking up ok? Are they feeling like they hooked up but aren’t connected well?

My swing cylinder is not very strong and will not push much dirt sideways when trying to fill a ditch or hole. OP's may not be strong enough to swing the boom from that position, but he should be getting some indication of it trying. Outriggers and curl should also be trying to do something.

Good idea, will try that, thanks

At last resort can make a tripod over back-hoe to get it up right.

I would say that if 3pt is working and remote valves are working, you are getting flow through the power beyond. I also suggest getting someone to help you with standing the hoe back up. An extra set of hands and eyes will go a long way. Just be careful.

Hook on to the bucket and pull the boom straight. Then get some blocks and a hydraulic jack and start the slow process of getting it upright.

The tripod and chain fall will be the easiest and fastest way.

Forget the temporary hydraulic hookup and just work on getting the hoe upright.

Do you have rear counterweight? It seems that a 4520 would lift it with appropriate counterweight.

Tractordata specs on the 4520 loader lists 3800 lbs lift to full height.
It should easily be able to carefully stand the hoe up with a little judicious rigging and a few spotters.
Getting it upright may make other problems go away.
