I have a Kubota 2350 4x4 tractor. I purchased a John Deere 67 loader. All measurments seem to work out for my tractor. I have welded and installed brackets to carry the loader. What do I need to add to my hydraulic system to make this loader work?

One thing that goes clunk for me is the fact that when you remove a Deere loader you usally leave the hydraulic controls behind on the tractor. When you remove a Kubota loader the joy stick goes with the loader.
So between the Deere loader and the Kubota tractor I bet you don't have a control system. ....

You need to go to a kubota dealer and buy the power beyond port off the hydraulic manifold. The part would be in there loader parts list I believe. ....

Thanks Art. My posts on hydraulics tend to be too long and I would have gotten tripped up anyway. The standard manifold on my Ford is combined with a diverter valve and send/return auxiliary system ports. So, from the factory my mid-80’s Ford is ready to go.
I have a set of in-line valves rather than a joy-stick myself, but the hydraulics are the same. I also have a third control valve section for rear hydraulics. Assuming that the valve assembly is a power-beyond type, there are send and return ports on the manifold that attach to IN and PB ports respectively on the valve assembly. The loader cylinder hoses are attached (usually with quick connects) to the control valve ports. It doesn't really make any difference which hoses go on which side of a control valve as long as both sides of a cylinder go the same valve. Reverse them and the cylinder just works the other way.
There are a couple of things that may not be quite straight-forward. First is to distinguish between the PB and TANK ports. Both are on the outlet section of the valve assembly. The PB line goes back to the manifold while the TANK goes to the sump. Normally there is a plug somewhere on the cases that can be removed to attach the TANK line. The 3ph won't work if they're reversed. If the valve assembly is for a loader, then one control valve probably has a float feature. Unless the assembly also has a valve with a regenerative feature for fast dump, the valve with float probably is longer. The valve with float normally is used for the lift cylinder.
Still too long eh? Darn Tom was off at our camp for a week. I must have missed this because the 'messages as posted' screen now seems to only contain one page so I can't scroll down to where I left off and start again.
