Backhoe fell over and died.

Discussing rigging to set the hoe up is distracting to the real problem. That hoe will easily right itself if properly coupled to the tractor.

Discussing rust or damage to the hoe cylinders is also distracting. It didn't tear itself up by falling over or by accumulating a bit of rust. Again, if properly engaged to the tractor it will overcome any forces that are being applied to the cylinders.

There's something wrong in the hydraulic hookup. The smaller hoses will only limit speed of operation, not pressure produced. Somewhere, possibly in the couplers as suggested above, there's a flow problem. Also as mentioned above, if there's any flow the elevated outrigger would easily function. The fact that there's no function of any cylinder indicates a problem with how it's coupled to the tractor.

Wish I were your neighbor, I'd come over and brainstorm this with you. It's definitely a K.I.S.S. problem.

Let's say everything hydraulic-wise is hooked to the tractor correctly. Could it then be a problem with valve priority and power beyond?

Just an example:
I have a steering valve that uses the power beyond port to feed the FEL valves. If I crank the steering valve all the way to one side or the other, I loose FEL operations until I back off the steering just a hair. It's because the steering valve has priority over the FEL.

Back to the OP's backhoe and how it's laying:
Could one of the cylinders be at such an extension that it's refusing to allow fluid to pass to the next one(s) down the line because it has priority over anything past it?

I'm not sure if that's possible. I understand if the valve is forcing a cylinder into bypass that you might lose power to everything else. But I don't think physical forces that are pushing a cylinder to maximum stroke would do the same thing?

Where's MadRefferree when we need him?? LD1 might also be able so shed some light.

I think it's already been clarified that there's only two hoses. I think he's not hooked up right at the tractor. Would have to stand there looking at it and studying it to figure it out. I'm slow that way.

Richard you are correct. The cylinder being fully extended would not cause loss of other functions unless the valve is still held open.

However, if pressure is on the cylinder, and the backhoe valve has been cycled, there could be enough pressure on the lines making it difficult to connect to the tractor. Possible that the OP has the hoses in the correct spot but has not fully seated the connections.

Also, it has been 15 days since we have heard from the OP. He may have found a solution.

Yes, I agree. Meant to mention your concerns about connection earlier and forgot.

Funny, I hadn't paid any attention to the timelines of the posts. Good catch. He's solved it or gave up by now!!!

4 gallons of fluid went somewhere, is there a cut hose or leak under the BH?

On a John Deere compact the power beyond is in the same circuit as the 3 point lift. If it lifts the hoses are connected correctly. If it won't they are not. The connectors suck. Mine look connected and either the Back hoe or the 3 point wont work. It's always the connectors are not correctly seated. If I install the hoe and it won't work I try and raise the 3 point. It won't raise and I know to disconnected and reconnect the fittings until it works. Did I mention they suck? They can connect to the point of being locked and still not release 1 of the fittings. Take the male fittings and force the tip against solid part of the unit and make sure the ball goes in. If there is pressure in the backhoe the ends of it's hoses may not be releasing. Hook them back together on the tractor and see if the 3 point raises. If it dose the tractor is good. Again it is possible for them to lock in even without pushing the balls on both halves of the connection. Normally when it happens to me pushing the male end against the edge of the backhoe frame releases a lot of pressure. And then all is well. On the tractor you can release the pressure by cycling the joy stick. That won't work on the backhoe as its pressure is contained in it. And yes both fittings will do the improper connection thing if there is a lot of pressure in the backhoe. they really are lousy fittings.

The OP hasn't been on TBN since October 11, so I guess we just wait and see if he comes back with some news.

I am hoping he is well. He did not strike me as the type to leave us hanging.

Yeah, me as well.
