Yanmar fx255
All of a sudden, the 3-point hitch hydraulics on my tractor stopped working, but everything else is fine. Does anyone have a diagram? Any help would be greatly appreciated.

Do you have a loader or any other hydraulic accessories on the tractor? Does the "UFO" tilt system still work?

The three point hitch on that model is entirely "fly by wire". There is no mechanical connection between the lever and the valve so, if the other stuff is working, the first thing I would check is the fuses and be sure all of the electrical connections are still plugged in. Also be sure the potentiometer on the three point control handle is still connected and moving.

Thanks for replying. The other components are still working fine. From what I checked, it looks like the two solenoids that open and close are bad. I tested the voltage, and it’s coming through correctly, so the problem seems to be with the solenoids themselves. Do you know where I could get replacement solenoids?

I think it would be pretty unlikely that both solenoids would fail at the same exact time. My guess is that something else is going on there. Maybe a bad ground?

I don't see anyone selling that Yanmar solenoid part number but I doubt that it is a Yanmar exclusive part. Are there any part numbers or a brand on the solenoid or valve anywhere?
