I have a Yanmar 1500 and just got done changing the transmission/hydraulic fluid and filter and went t o raise and lower the 3 point hitch. It went up but would not go down. I didn't have an attachment on it so at first i thought it wouldn't go down because it didn't have any weight on it. I put my weight on it with the lever in the lower position but it didn't budge. Could I have somehow got it stuck in the up position because I operated it without an attachment on it? Could there be air in the system from when I drained the fluid? Dump valve failed?
3 point hitch won't go down

Welcome to TBN...........
Have you checked the control valve below your seat? Usually there is a knob the controls how fast the 3 pt will drop. If the knob is fully clockwise the valve is closed and won't let the 3pt. go down.

Trace from the knob back...rod connections,maybe build up on arms.
Its working now. When I started looking into it a little more, I noticed that it looked like the actuator piston wasn't coming out enough to dump (it was sticking). I sprayed a little WD-40 around the actuator piston area and cycled the 3 point lift a few times. It works great now!
