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.

I bought a valve and handle, the valve is a standard part that someone had-then I bought a bracket, had some hoses made at a shop, and I've been happy. Not hard.

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.

For the non-reversing applications, I have my hoses tagged as to which is which, and a nut/bolt through the "not allowed" slot.

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

I know Rol Farrar (Magnum RT) did one with a tcv and has pics of it either at MTF or at the Yahoo site, it looks very professional and looks factory.

Sorry my fault-there's all kinds of crazy fisherman terminology. I should have said winch head. When its turning you loop rope around it and it will haul stuff up out of the water or an anchor line.

Caseman2 Thank you. It would seem my valve would be very similar to the Case TCV.

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?
