deere 755 3 pt not working

[somanytractors]

I have a 755 I got not running and don't know it's history.
It has the levers and quick couplers for a loader but no loader.
It runs and drives great and the power steering works great.
If you move the lever for the loader it will bog down like it should.
The 3 pt does nothing at all. No bog no lift, nothing.
I was told that on the 755 if you remove the loader you need a jumper to get fluid to the 3 pt.
This makes no sense to me as the loader only has 4 hoses 2 for lift and 2 for tilt I would think.
Anyway, if I do need to jump it I dont know where to put the jumper.
The couplers for the loader are numbered 1, 2, 3, and 4.
Do I need a jumper or is it something else?
I've attached a few pics. I'm not at all familiar with these little deeres so I really need it spelled out.

Any help is greatly appreciated.
Thanks
John

Your tractor is really a Yanmar. Either ask in the Deere section or the vintage Yanmar section.

The TM1360 Technical Service manual can be found for free on the YTOG site. This will show you the typical hydraulic plumbing with the Yanmar loader on the JD755.

If the directional control valve stays with the tractor when the loader is removed it should not require a jumper for the 3 point to work.

How many lines connect to the control valve including the four for the loader? 6 or 7?
