weird issue with fel valve

[J_J]

You might also remove the loader relief valve, and inspect and clean if necessary.

yeah, swapping hoses wil be my next troubleshooting task. Thank you.

In a similar thread I posted in the Kubota forum we were speculating there may be some small chance the spools have been switched. I don't know if that could make any sense of the problem or not.

JJ, I'm glad you said that. There isnt a relief valve on the control valve, it must be somewhere else on the tractor. Any thoughts on where?

Yep, look under the right side foot rest for a hyd block. Some tractor relief are located on the hyd block.

Has anyone worked on the tractor or moved any hoses?

In an open center hyd system, there is a path for the fluid to flow until it is redirected by a valve.

That is assuming that all hoses are connected and all vales are working as the should.

Now, if everything is connected correctly, and things don't work as expected, then something is broken or not operated right.

Your hyd block may look similar to this.

Yeah I have a hydraulic block like that. I'll check on it too. The hydraulics have been worked on. I don't know when or by who but a bradco 511 was added. It has a t fitting that attaches it into the return line and you swap it's line onto the pb port at the loader valve (there's quick connects One for 3pt hitch, one for backhoe)

With no BH installed, your hyd path should be like this.

Pump to hyd blk, then to FEL, FEL OUT back to hyd blk PB to 3pt, then to tank.

All return hoses should go to tank unimpeded.

If BH installed, then the PB out of the hyd blk would go to the IN port of the BH, and the BH OUT hose would go to a return hose.

You probably would not use the 3pt with BH connected.

The bolt on the bottom of the hyd blk, is the tractor relief.

You might check the relief pressure.

Yeah. That is all correct and that is how it is plumbed
