Let's say a guy stumbles along a Case tiller and might be able pick it up cheap, what's the pro's and con's of making up their own PTO valve assemblyand lines rather than to find a orginal Case one?

Both cost and functionality are a concern and I'm not over overly concerned about keeping it orginal but rather fuctional as a tilling machine.

What you need is a motor control valve with detents and they are readily available at hydraulic supply vendors for around $100. You can fabricate a mounting bracket fairly easily and use hoses to connect it. The part that requires a bit of design/fabrication skill is making a lockout so that you don't accidentally engage it in the wrong direction with a non-reversible motor--e.g. a hydravac. If you are just going to use it for a tiller then that is a non-issue.

I've connected several PTO's with hoses--both custom and off the shelf. If you go custom you can get a little neater installation but it will more than double the cost. The trickiest connection is to the travel valve as the hose needs to drop down to clear the frame--a couple of 90 degree street elbows make that easy.

Bart/Group:
Here is a control valve that came off one of my fishing boats. It was used for a cat head. It goes from 0 to full speed and will stay at whatever speed you choose. I think it may be a Gresen. I has K14P and 21 stamped on one side. Wouldn't something like this be nice for a tiller because you could regulate the speed? Would you want to regulate the speed, I don't know.
I also have a Vickers V20 hydraulic pump and Pitts electromagnetic clutch and aluminum hydraulic tank in storage for some future project.

While I hesitate to further display my ignorance, what is a "cat head" ?
Thanks

Maybe it is buried in there, but I did not see mention of a relief valve. There must be a relief valve in the PTO , set to appropriate pressures (around 2200 psi, individual specs across the years) to protect the system.

As a reminder, one flaw of torn down/parted out 3100/4100 series tractors is that the PTO did not have a relief in it. In that tractor, the relief valve is a completely separate component, protecting the whole system.

Brian: That's a good question, I wonder if the valve I posted has one?
