Bucket/Loader for JD 650 revisited

I had posted before about adding a loader/bucket to my 650. I was properly warned that the hydraulics are pretty wimpy and that I may not have the proper hydraulic block.

But... I found this. This is the hydraulic block under the seat. (see pictures) The lines come in from the pump and operate (I assume) the 3-point lift. There are a couple extra outlets.

Like I had said before - I really want a bucket for some very lightweight duties around the house like relocating some gravel from the bottom of the driveway to the top. Are these hydraulic ports where it would go? Or is that for something else completely?

(and by the way... hour meter is currently at 375 hours :shock

If you like, I can get some pictures of how the
loader on my 750 is plumbed. They're essentially
the same tractor.

I'll check back in the morning.

I would like that very much. I took a closer look and those two ports in the left side of the picture are labled "I" and "O" which seems like a good indicator.

The two ports you see are the ones where the loader valve was plumbed into. The steel line you see is the high pressure line. I think the ports are: top pressure and bottom return. This is by memory. So it is worth what you paid for it. LOL

The picture is of a JD 650 with a 67 loader on it. IF you look real close you can see the hydraulic lines. The more common loader is the JD 60 loader.

That helps a lot. Back in this thread http://ytforums.ytmag.com/viewtopic.php?t=930989&highlight= you had said,

It may not even have external hydraulics on it. It was an optional kit on the 650/750. I don't just mean the SCV valve. It could not even have a way to plumb the loader in with an external valve. It was a separate block.

Is it safe to assume from my photos that I do have the means to plumb an external valve?

You'll have to forgive my dumb questions. I grew up restoring old tractors with my Dad, but we never really dove into modifications or the hardcore tech. If it had hydraulics, we used them. If it didn't, we didn't. Its funny that I have so much experience with tractors, but so little actual knowledge about the deeper stuff.

.... and not that anyone asked, but here are two photos that you might enjoy. The first one shows the whole tractor with a Bolens/Sears fixed bucket that fit on the front like it was designed for a 650. I slapped it on there to run the brush hog since I need some weight up front and I can drop some concrete pavers in there for ballast.

The second one shows the hour meter. Yep. Not bad for a FREE tractor

The problem is that the factory setup was a whole bunch of stuff that all had to work together. They installed a pressure relief valve in the two loader valve supply lines. This valve was different if you had power steering or not. So if you accidentally ran the tractor without hooking the return line back up it would not blow a line. Then there where three different Hydraulic valves used that I know of. Where you find them in the parts system now it is on computer is beyond me. I helped a parts guy look for a half an hour and we never did find them in the computer. He went and got the old Microfiche cards out.

I don't have the service manual on this tractor. I would need to look at the hydraulic flow chart to make sure you can get a external valve to work without any problems. The issue is that the hydraulic system on this tractor is a open center one. Meaning that the oil has to flow all the time. So when you tie into it you have to do it right or you can make something be blocked or have an open circuit in it where nothing will work.

Have you even found a loader yet that will fit??? You luck out and find one that came off of a JD 650. But then the valve may have stayed on the tractor.

There is a Compact tractor parts yard in western Kentucky. I have gotten parts from them before. They may have the complete setup for a JD 650.

You will need an open center loader control valve with a power beyond port. In one of those 2 openings behind those plugs there is a small allen headed pipe plug goes into it to block off the oil flow,then you run the hoses to the valve and the power beyond back in so as to run the 3 point. The return goes into the tranny case.

jdparts.com may show some of the routing under the loader models and possibly under the tractor model aux. hyd. control valve kit.

Woods or other companies likely still offer a loader and valve package to fit this tractor. I doubt Deere has anything to fit them anymore ?

Mike I have to dis-agree. The oil has to be returned to the other port right here or the three point does not have any oil flow. If you look at the pictures I posted earlier you can see that. This tractor has an open center system on it. You have to keep all the hydraulic valves in line or any down stream from where you dump of the oil will not work.

To my knowledge they never made a power beyond for these little compact tractors.

Please reread where I said run the power beyond back in to get the 3 pt to work.

And yes the John Deere valve made for these is a power beyond type valve.

Thanks for the tips. I guess my next step is to contact my old buddy who used to run a JD dealer. He might remember since they did a lot of compacts back in this era.
