When I raise it again it stays up but won’t drop. The hydraulics on the 3-pt work fine, go up and down. Also, when I drained some hydraulic fluid where the line attaches behind the seat I saw water in the line. How can water get into the line? Thanks for your help! [Reply]   [No Email]

Remove the tip on the hose and replace with a new one. There is an Oring that blocks oil from returning to the sump. Joe [Reply]  [No Email]

If it was working properly, when was the last time that it worked, and what has happened to the tractor since then? Is it stored in a barn or garage, or out in the weather? It sounds like the spool valve for the lift cylinder has a clogged port, or the lines aren't hooked up properly. If you found water in the system, then it may be rust in the valve or some other kind of gunk blocking the port in the valve. There are many ways that water could have gotten into the system, most likely culprits are condensation and rain water. Once water is in the system, you will need to drain the entire hydraulics system and flush it out. Best thing to use is a combination of diesel fuel, ATF and rubbing alcohol. The diesel and ATF will help clean any gunk out, and alcohol will help get the water out. It may take several drains and flushes depending on how bad it is. [Reply]  [No Email]

It had a leak on the lever control box and hasn't worked right since. Only had to tighten a plug to fix leak, but I assume air may have been able to get in?? There are two hydrolytic cylinders on the loader, what is and where is the spool valve located? I'll flush the system to remove the water, but I don't think that is causing the problem, do you?

One hose comes from the rear hydrolytic sump and up to the loader control levers. The other hose goes from the ASC to the other side of the loader levers. Rear end sump looks a little cloudy so it could have some water in it. Loader doesn't have its own filter. I didn't bleed it before installing. How do you bleed the oil from loader?

And yes, loader valve lifts boom, but won't drop. But if I loosen hoses and drain the cyl or disconnect hose to sump and push in pin with screwdriver pressure is released and loader drops. Thanks for your help; hope you can diagnose the problem!!! [Reply]  [No Email]

I took the qd off both lines last nigt, pushed the pin in on the male side and fluid came out and loader came down. How do you check the qd? How do you check the female side? [Reply]  [No Email]

Remove both the male and female QD and replace them with a standard coupling adapter. Mark [Reply]  [No Email]
