A member asked me to follow up a comment on the lift circuit selector that I have set up on the demo Ingersoll we keep.

A lot of Case/Ingersolls are set up with a fairly simple mechanical valve, which selects between 2 output circuit to allow selective control of the mid-lift cylinder or an aux cylinder, such as the 3 point hitch.

Some time back, I located a very nice, compact 3 circuit electric poppet valve and applied that to our Ingersoll to demonstrate some of the versatility of the machine. Before you ask, no I don't know where you can find this valve now ... it appears to be obsolete from the source I had ... but read on.

This set up is simply an electric poppet valve ... actually a gang of 3 poppet valves in a single block ... used to turn on or turn off various circuits. In my application, the electric poppets have 1 normally open (the mid lift) and 2 normally closed (front and rear aux) poppets.


In one photo, you can see two red switches lit up under the steering wheel. The 3rd switch is hiding off to the right, in the black ...

All the switches turned off ... the mid lift functions independently.

Turn the center switch on, and all the hydraulics are turned off. Turn the outboard switches on and the front and rear aux are operating in parallel.

With the electric control, you may operate any combination of the circuits simultaneously ... not necessarily a highly useful feature, but I think the statement illustrates the function of the 3 independent poppets.

Switches conveniently located in front of the operator, with wiring well protected up inside the chassis and steering tower.


An aux circuit runs to the front ... nominally to operate the hydraulic angled snow blade ... no getting off for switching around while plowing.

An aux circuit runs off the back to the 3 point hitch, which hangs a big rear blade for the winter. I keep the 3 point hydraulics on flat face, zero leak quick connects for easy removal.


The main valve block is mounted directly under the RH foot rest. Leaves plenty of clearance height, even with decks fully lifted. This location might be a bit too tight for a 200/3000 series clearance height.

The lines from the TCV lift circuit simply feed the front of the valve block and the 6 lines going off are 2 each for the 3 circuits.

To operate the lift or aux circuits, you just set the switches select your circuits, then use the standard lift lever to control the lift side of the TCV.


All the hoses are tucked up neatly in the chassis and the chassis close out panel is still installed under the tractor, to properly manage the cooling air flow in this 'backward engine' 4000 series.



As I noted ... I don't know where to source this specific valve presently. However, Surplus Center sells economical, simple electric poppet valves which achieve the same result when run in a gang of 2 or 3 ... if with a slightly more complex package of running the lines.


One reason I love this product and support the brand is the extent of versatility in a real hydraulic system ... that and the 'still build them like they used to' 40 year ruggedness, that just keeps going and going when well maintained.

That's an interesting set up "Bee", but were all old school guys here, were used to A lot of Case/Ingersolls set up with mechanical valves.
Mid-lift cylinder or an aux cylinder, like a 3 point hitch.

This set up would be usefull for a lot of us for sure, but I bet ya there would be a hefty price tag attached to that?

(what size hydraulic hoses run troughout this tractor, they look small to me?)

The single poppet valves are about $60 each. Not overboard. Certainly the hoses and fittings add up. You can control the cost or the amp up the utility and installation neatness ... Then just a couple of toggle switches.

The hydraulic lines are mostly 1/4" ... really no need for more in these little cylinder circuits.

60 bucks for a single valve. :fing32:

What could someone do with just one? can it be plumed to replace a selector valve that is used to seperate a lift and angling cylender on a rear 3 point hitch grader blade? :trink39:

do you have any picture of the valve in question?

I like it!! :fing32:

This I will definitely keep in mind when I start working my project tractor.

And a hearty 'Thank You' for sharing with us, sir.

A lot of Case/Ingersolls are set up with a fairly simple mechanical valve, which selects between 2 output circuit to allow selective control of the mid-lift cylinder or an aux cylinder, such as the 3 point hitch.

Would this valve also be called a 'lock-out' valve?

Some time back, I located a very nice, compact 3 circuit electric poppet valve and applied that to our Ingersoll to demonstrate some of the versatility of the machine.

The reason I ask this: Another make popular on this forum has this discussion come up fairly often, where an owner with a new GT runs into the roadblock of having multiple implements on the machine, with the need for 3 circuits. For instance, a snowblower with hydraulic lift, (one circuit gone) and hydraulic spout rotation. (there goes the final circuit available) Now, what to do with the rear blade? Lock it up, and manually change it when needed.

Well, we will tolerate that no longer. I googled 3 cylinder electric poppet valve, but hardly understand what I'm looking at. But after I read your post another 5 or 6 times, and do some research, I might have the basic concept down.

Thank you for sharing this, Brian. It is much appreciated. And since you've got this done, what to do for the rest of the day?

Here is a good example of a true electric selector valve, set up for 2 circuits. Could easily be ganged to have 4 ...

http://www.surpluscenter.com/item.asp?catname=hydraulic&qty=1&item=9-5117

I'm not presently finding the true on-off single poppet valve, which I thought Surplus was carrying.

A "lock valve" is something entirely different ... can't say I've heard of a 'lock out' valve.

The JD guys use a lockout valve. It's just a needle valve installed in line. I added one to my 446 three point so the hitch can be locked in the up position and then the deck will function as normal. If I'm using the three point the deck is off so the cylinder can cycle and not hurt anything.
On the Deere's the midlift cycles first then the front ports so even if the deck is off they have a delay on the blade angling.

Your setup is a little more sophisticated and way cool Brian. :fing32:

Yeah. I realy like this concept of the electric poppet valve. I could select front curl cylender, or rear 3 point hitch lift cylender in one flick of a switch.

AND return the entire loader plumbing back to the way I had it before. It seemed to work very good. ONly now I would have a 3rd function I was looking for.

Brian, youre a Good man. You gave me a new project for this spring.
