Two Cylinders with 1 Remote

[JoshJ]

We have a Ford 5610 with only 1 hydraulic remote off the back. Looking at getting a grain drill with two cylinder circuits on it. (One for drill, one for the thing in front that works the dirt a little bit, dont know what its called).

Here's my thoughts, any suggestions would be greatly appreciated:

1. 'T' the "up" and "down" lines from each cylinder into the respective ports on the tractor. This will work OK b/c depth can go to a preset position, and the cylinders moving more or less together is doable. What does a 'T' for this look like? Do they have QD 'T's? Or whats the way to do this?

2. Buy a spool/stack valve and run it from that. I'm assuming this hooks into the remote, and you put QD's on it, and go to work. We would need one with detents so you can just pull it and it pops to neutral when it strokes. As far as options, seems like open center is the way to go, and maybe get power beyond as well so we leave the front end loader hooked up? i dont think the loader circuit has PB.

3. Speaking of the loader, we could put QD's on the joystick, pull the loader off, mount the joystick on the tractor, and use that. that would be OK, but it'd require hold the lever all the way until it raised/lowered, which doesnt seem ideal to me, plus it has to relief or stall so you know its there.

Anyway, I've done some looking, ebay, surplus center, and on the forum - not really sure where to go now.

Any words of wisdom?? Thanks

If the cylinders are placed in parallel with a "T", the fluid will flow where the least load is, so if one cylinder is under a lot of load, when you feed pressure, it mon't move untill the other one gets to a point of matching the load on the first cylinder than they will both move. In some cases, this is desireable, such as dual grapples on a bucket and trying to pick up odd shaped loads such as a stump. In your case, why not just put in a simple 2 spool open center valve with the supply and return lines hooked to the remotes on the tractor and the work ports on the new spool valve going to each cylinder.

How this would work, is you send fluid to the remote, then use whichever spool valve is needed to work the desired cylinder on the drill. If you want it to automatically stroke to the end then kick the lever into neutral, perhaps a logsplitter valve would work, but that would only provide this feature in one direction. The other direction would have to be held till the desired cylinder position is reached. A dual direction kickout is possible, but with a not so common valve I think.

Thanks for the input Ron.
What i was thinking is that the "T" would raise one first then the other, which would work okay, sorry for not mentioning that.

i saw some 3 positon valves with detents (not float) on Surplus Center, so I am thinking those would be the way to go. anybody know any brands to go for/avoid?

Isn't that how a bat wing mower works, lifts one side then the other.

You could plumb in a manual selector valve, work one cyl. and then move the slector valve and then work the other cylinder.

Good luck Petert

I wasn't sure what the application was exactly and if the 2 cylinders did the same thing only in different places, like lifting batwing mower decks or dual grapple arms.

A standard detent valve won't kick out at the end of the cylinder stroke. you need one specifically designed to do that, like a logsplitter valve is.

 

[JoshJ]

Thanks Peter, I'll look into that.

Ill check out what you said too, Ron. I guess I was thinking to find something like a tractor remote that'll kick out. maybe not all tractors do that, and its more on the ag tractors than on a CUT.

 

[PeterT]

Does the remote control valve on your ford tractor kick out now when the cylinder reaches the end of its stroke? If so then is still would with the slector valve.

Good luck PeterT

Peter-

I think so, not positive b/c i havent used it, but it has detents (to run the FEL) so Im guessing it must.

Have been exploring the T option, as it would be more economical, and at this point we dont have a need for extra hydraulics for other stuff, so it is harder to justify extra valves or selectors.

The other thing is simplicity of operation, especially when coming to an end of a row - easier/quicker/less motion is preferable.

Thanks for the input tho guys. if we have a need for more hydraulic things in the future ill keep this in mind. Greatly appreciate the help

I like ronmar's idea. This is how JD does it when you buy a batwing mower that needs 2 circuits and you only have 1 remote.. IE.. they sell you a 'valve' kit' which provideds 2 cks from the 1... etc.
