FEL not working after picked up by tow truck

[Wayne County Hose]

This is why you don't have a car guy pick up a tractor or a tractor guy pick up a car.

Usually when something like this happens, there is a buildup of pressure in one side of the cylinder. That pressure works it's way back to the valve where it can go no further. Usually the weak point is the valve but sometimes the piston inside the cylinder. I think maybe you broke the spool inside the valve. You can still move it one way when you stroke the lever and pressure may sometimes push it back to neutral. This is my theory as to why you have intermittent control. A broken rod end inside the cylinder will also act like this. Hopefully you get it figured out. BTW, this is just my theory and personal experience. If I'm wrong, it aint the first time and certainly won't be the last.

would it help to put in a "t" and send the pump output to both the FEL and backhoe seperately?

No, You cannot Tee high pressure hydraulic lines, all valve must be in series for them to work. The fluid will always "take the path of least resistance" so when you operate a spool the fluid will flow through the other valve.

You can however Tee low pressure return lines.

Usually the FEL valve is first, then the 3PH and/or backhoe.

Since the the pump output goes to the BH first...I would guess that one of the levers is not centering causing the fluid to go directly back to the sump rather that the FEL valve.

Check to see if the three point control is all the way up or down.

I think you will find sequence is 3ph then loader then back hoe in most tractors.

There is a priority valve and if the 3 point is active (all the way up or down)
it will take priority and no functions on the rest of tractor.

The 3PH valve is locked with a pin and never used. the 3PH hoses in and out, go to the FEL control valve. I have though about just removing it as it isnt used. with a full frame backhoe, there is no more room for attachments.
