Three point arms won't go down. Please help.

[marcjewell]

Sometime during the process of shimming my hydraulic pressure relief valve I managed to screw something up with my three point arms. They appear to be in the max up position at the arms. My control lever does nothing to move them. When I pull the three point lever about 80% up I can hear them activate and I hear a small/regular load sound on the engine. But like I said before they are already all the way up.

I turned the decent relief knob all the way out, stood on the arms and they still won't budge a mm. I even took the decent knob all the way out, and nothing.

The loader works perfectly fine. There is no lever to choose loader or three point on my tractor. I have a 1986 Kubota B700 HST.

Thx in advance.

They have no down pressure , you might need to have someone stand on the arms whie you pull the lever, to get them started down

Go back to your other thread as you have messed up the valve, what you shimmed was not the relief valve.
Running it as you have with a messed up valve can damage the pump and the system.

I noticed immediately...and took out the shims...also, I wouldn't think that would have anything to do with the arms simply releasing down. No pump required I would think...thx
