JD5400 / JD770 / AC 160
A quick intro before I beg for help! I live in Central Indiana and have a small acreage. I use to landscape, and have a 1992 770 with loader. I bought a 5400 a few years ago with a loader, and a buddy and I have just traded for a 1998 5310 w/ loader for him.

We just traded a guy for a 1998 5310 with 645 hours. The machine has set outside without being used for probably 7-8 years. The previous owner couldn't get any of the hydraulics to work, so he just let it sit. The machine had a big backhoe attachment on the back that kept him from getting to the hydraulic screen when I traded for it. The clutch was froze up, I got that free. No hydraulics would work, no 3 pt., no loader, no steering.

I got the tractor home and drained the hydraulic fluid. There was 2 gallon in the tractor. I pulled the screen and it had a paste-like slime all over it, that nothing was getting through. I soaked the screen and scrubbed it lightly, it is now clean. I dropped the MFWD gearbox, and replaced O-rings and a seal on the output shaft that the Hydraulic fluid was lost from, I think. Changed the hydraulic filter, put the Hy-guard in and I now have steering, the loader works, and the rock shafts raised, where it wouldn't before. I tried to put the 3pt. back down and it won't go. I made sure the rate of fall knob was all the way open, and I think it is, but it doesn't move very freely. I am going to remove the seat and take it out and look at it. Like I said, I think it's all the way open; what other things should I do, if the rate of fall valve is OK?

Also, I noticed the PTO is constantly turning, even if the PTO is off. Not just spinning a little, but it is on. I assume that clutch is frozen, as well. Am planning to put a bush hog on it and hit some thick stuff to see if I can free it, if I can ever get the 3 pt arms to drop to attach a bush hog!

It's a shame this tractor was let go so long, but I think I'm about to bring it back to life. After 3 wasp bites and a bee sting, I think I have killed about all the critters that were living in her. Thanks for any help!

I am guessing the rockshaft valve is sticking. Corrosion or dirt and just needs to be taken apart and cleaned.
Hard to believe someone would just let it sit and not get it fixed, for a low hour machine.

If there were any signs of water in the hydraulic fluid plan on new brakes

Fluid looked rough, not sure what it was. Brakes seem to work well, but I'm worried about them. You think it's the rate of drop control, or the actual control valve for the 3 pt.?

actual valve for three point

Any idea how to free a stuck PTO clutch on this thing? Got to get the 3 pt. to lower first.

And the 3 ph will not move up/down with the tractor off?

Might have to decide just how far you want to go yourself, but I'd start poking into the rockshaft and see if there is something broken or put together wrong such that the rockshaft arms cannot move and let the 3 pt move down.

Once you have the 3pt hitch working you might put a brush hog on and get it up to PTO speed and then push in the clutch and see if the inertia of the brush hog spinning breaks the clutch free.

A little update. I removed the rate of fall valve for the 3 pt. Oil shot out and the 3 pt gradually dropped to the bottom, as it should. The rate of drop valve looked fine, but I reinstalled it and nothing new. Started the tractor and moved the 3 pt. control up a little and the 3pt. raises a little. Raise to the top, it raises to the top. The thing just won't drop. I'm guessing that I need to pull off the selective control valve block and the controls for the 3 pt and clean them. Probably full of the same gunk that the screen was plugged up with.

The PTO is still running all the time, regardless where the linkage is set. Hopefully when I can lower the 3pt, I can put a bush hog or my 3pt tiller on and jar it around some to free the clutch.
