stuck 3 point

Postby brokentractordean » Sat Apr 25, 2020 8:08 am

I have a yanmar us 31d tractor. It has 105 hours and sat for awhile. The three point hitch is stuck up and the hydraulics are at full pressure causing engine to load up. Fluid had water so I changed it and filter. THREE POINT STILL WONT LOWER EVEN AFTER MONTHS WITH LOAD ON IT.I can pull hose to lift and let it flow in bucket and engine runs fine. I removed flow control valve and fluid srayed out and valve shot out three point dropped. I cleaned and reistalled and three point lifted and stayed engine still loaded up . It doesnt matter if valve is open or closed.
