We got a C that we want to do some plowing and such with but it requires a hydraulic port to plug the line in. I think I've seen people put ports on C's before in pictures but havn't actually done it myself. Can someone explain what actually needs to be done. This C has been sitting for 9 years and were anxious to go out and do some plowing! Thanks!

Thanks for the responses. Hopefully I can put her plowing!

Do you need to use the Touch Control at the same time? If not, here is the quick way to hook up a remore valve.

Hook a hose into the high pressure tap on the Touch Control manifold (same place everyone else is talking about). Run this to the inlet of a valve. Run the return from the valve into the filler of the Touch Control reservoir. Hook your cylinder to the valve in the usual fashion.

Run one of your Touch Control arms all the way to one end or the other of its stroke. Take a piece of chain and tie the arm in place. Move the control handle for that arm all the way the other way and leave it there.

More than one way to skin a cat (or hook up a hydraulic remote). Your plan would certainly work as long as you did not want to use the Touch Control Rockshafts.

Here's a link to some of my photo's showing how the remote hydraulics hooked up for my new 3 pt hitch.

Clyde, thanks for posting those pictures again. I looked and looked trying to find the post and never did find it.

A while back someone posted pictures of the set up they got from Saginaw County Tractor with their 3 point hitch for the C. I suppose you could buy just the hydraulic parts from Saginaw. I believe the post said the cost was $100 plus shipping. The setup included a machined block that mounts between the hydraulic manifold (the pipes from the touch control to the pump)and the touch control. They also include a spool valve. You have to supply the hoses and fittings and couplers. Once the block is in place, you take the rear plug(has a 1/4 inch socket head plug in it) out of the manifold. That is the supply to the spool valve. The return from the spool valve goes to the new block. I've thought about investigating and getting one of these. I did take out the plug out of the manifold and stuck a gage in there to see how much pressure. My C makes max of 1500 psi, which I think is about the specification.

A person could build their own adapter from a 3/4" thick steel block about 2" x 5". Its only purpose is to allow hookup for a remote return line. The pressure line hooks up to the 1/4" test hole in the original block. The adapter just needs staight thru holes for the bolts and supply/return lines. The return hole in the block is tapped at a right angle to hook up the remote return line. I wondered if the 1/4" test hole would have enough flow out to the new cylinder on my hitch, but it moves the 3 pt up and down as fast as any hitch I've seen. Another option would be to put tees in the steel lines between pump and tc unit. You need tees to keep the original tc unit in the spool for a reservoir. Besides you can still use the orginal tc for belly mount implements. I suspect tapping the steel lines might be more expensive than the adapter though. Besides that does something to the original tractor you can't undo.

I've not seen the block that is added, but I would think the pressure side of the block could not have a hole straight through. The suction side of the block needs to have a hole straight through. The pressure side would need to have a hole drilled part way through from the Touch Control unit side and then another hole at right angles which comes out for you to attach the return from the remote valve. That way all the flow from the pump goes through the remote valve all the time, but the Touch Control still has the same supply it always had except when you operate the remote valve.

Haas.....I recently bought a newly manufactured block (that goes between the manifold and Touch Control unit). The pressure side hole WAS drilled all the way throught the block. The supply hole was also drilled all the way throught the block and each of these holes had a seperate hole drilled into it from a right angle so that you could tap the new hydraulic lines into the new block. That arrangement seemed kind of strange to me cause it meant, like you were saying, that the new remote hydraulic valve that I wanted to add would be in paralell with the Touch Control unit and I wasn't sure that would work. So, I drilled/taped and capped the pressure hole at the inside of the manifold. I removed the pressure line cap on the outer side of the manifold and used that outer side manifold hole to supply pressure to the new valve. I then connected the new valve's return line to the right angle hole in the new block at what WAS the pressure hole. (and I just capped the new block's orginal right angle return hole) It works fine and I can always remove the new block and manifold cap if I ever want to return the tractor to orginal condition.

Thought I knew what I was talking about till I read your message so I'm trying to remember. But as I recall both lines went straight thru the new block. The original flow and controls work in parallel with the new ones. You can use them both at the same time at least with no load. But I'd be surprised if that little pump could power both at the same time under full load.

If the hole is drilled all the way through, the only way you could use the remote would be if you use both the remote and the touch control at the same time. If the touch control is not active( that is moving the rockshaft arms) there is no pressure at that port. I've had a gage on there and pressure is only made when the rockshaft arms are under a load, causing resistance. Of course there will be pressure all the time if your touch control is out of adjustment and you have the levers fully retracted, but that will be evident with load on the engine and eventual overheating of the hydraulic system. You can't operate like that for long without some problems due to overheating. If you are going to use the touch control as a back pressure and set it so it creates back pressure all the time, then you would have to run the return from your remote valve to the other side of the manifold, which is the suction side of the pump.

After thinking about my setup and taking another look at the tractor, gotta admit you're right Haas. Here's how the Saginaw adapter is setup. The return line on the new adapter goes straight thru and has no other connections to it. The pressure side of the adapter doesn't go all the way thru. It is open on the tc block side of the adapter and has a right angle connection for the new open center spool valve. In other words with neither system being used the flow is from the pump via the test hole on the manifold block out to the new center open valve and back to the pressure input hole of the tc block. Instead of parallel the new system is in series with the pressure side of the original system. I was thinking both went straight thru because the gaskets Saginaw supplied were original style with holes for both. As you can see I know just enough about hydraulics to be dangerous.

Haas has it right. The pressure hole cannot be drilled clear through or it might as well not be there.

In the owner's manual on the SC with fast hitch it shows an optional quick coupler to the fast hitch cylinder. You pin the drawbar in a staionary position and uncouple the hitch cylinder, then use the hook up to power a remote cylinder on a plow or disc, etc., but this requires the fast hitch. Just a thought, I know a straight C dosen't have fast hitch.
