Hi all, it has been awhile since I posted here. Hope all is well.
I have a IH1000 loader on my little cub tractor, I would like to add another hydraulic cylinder to the circuit to run the rear rock shaft on my tractor. Basically relieve the touch control unit of those duties.
I'm not by any means a hydraulic pro, so I'm stumped on how to plumb in the third valve body. Do I put it in parallel with the current loader valves (tee into the inlet and outlet lines)? Or do I run it in series ( run a line from the outlet of the loader valves to the inlet of the new valve, then run a line from the output of the new valve back into the bypass block?
Do I need an open center valve?
The last thing I want to do is dead head the system, so you see my dilemma.
Thanks for any and all help,
Herb

As long as they are both open system valves (spools) dead heading won't be an issue. The second option you presented would be the simplest and probably the cleanest way to do it, either before or after the loader valves. Without some sort of proportioning valve I don't think there's an advantage to a parallel circuit.

Re: another hydraulic question, and it's a doozy.
Herb, is your rear rockshaft hooked to the TC system currently and you just want to change to a separate cylinder? When installed as it was designed, the IH 1000 loader works independently from the front rockshaft on the TC.
Do you have the loader manual? If not, the owners manual and parts manuals are available above.

Re: another hydraulic question, and it's a doozy.
You need an open center valve.
Plumbing is real simple:
Mount the new valve somewhere convenient.
Remove the hose from the OUT port on the loader valve. Connect it to the OUT port on your new valve.
Connect a hose between the OUT port on the loader valve, and the IN port on your new valve.
Pressures aren't high enough to worry about "power beyond" or anything like that.
Like others have said though: Does your Touch Control work normally now, with the loader installed?
If you have to chain the touch control arm in place to allow the loader to work, you don't have the proper bypass block installed.

Follow the link in my sig line to my Splitter Project - you will find the solution right there... rather easy as I ain't no hydraulics guru -- but Rick and a few others are and they helped me figure it all out.

Re: another hydraulic question, and it's a doozy.
Awesome, Thanks Guys, I thought hooking it up in series was going to be the way to go.
My touch control unit is working, and the rear rock shaft is hooked up to it, I was just looking for more lift power.
The front end loader is very strong, the rear lift, not so much. By my estimation, about 300 lbs. is its limit. It's always been that way even before adding the loader. Maybe my touch control is a little weak, or maybe I'm trying to push the limits of something designed to lift a one bottom plow. I want to expand on my rear carry all and the first step is to upgrade the lift.
thanks,
Herb

Re: another hydraulic question, and it's a doozy.
I feel like i read somewhere that 300 lbs is what the TC was designed for. mine struggles to lift the fast hitch disc with 2 cinder blocks... I don't know much about hydraulics, but I always thought it was the pump that lacked in strength, not the cylinder. my reasoning was that it lifts more when the engine rpm is higher.

250 to 350 is about the weight limit .. from the GSS-1024 - Farmall Touch Control Serviceman's Handbook
The added valve should be able to operate the rear rockshaft separately ... but I am still thining on it .... there is something not quite right .. I will get it eventually... I want to be able to do the same thing - operate front/middle and rear rockshafts separately.
I wouldn't take the TC out of the equation. It is quite capable of doing the work you need it to do so no need for an extra hydro unit. What I am thinking is that it the rear rockshaft is disconnected from the TC then the loader will only react then the stock TC lever is activated. With the secondary cylinder plumbed through the by-pass block and it's own O/C valve - then the secondary cylinder will operate the rear rockshaft independantly of the front. .... just runnin me brain here and trying for some exercise ... trying to visualize.
With my splitter project I did not separate the rear rockshaft - which is something I should look at doing. Probably another valve needed - good thing I have a few more of em hanging around
