Would this work ?

[Biggreenavalanche]

I have a Mahindra 2012, 4035 PST, came from the factory with one remote, I have the kit for a second remote, I want to also have a 3rd/4th remote who's sole purpose is for hydraulic top and tilt...would this valve/spool work for that pupose ? And, could it be further plumbed for true third function on the loader ? (for future root rake grapple) I do like the idea of top and tilt associated with a joystick...

Surplus Center - 2 SPOOL COMPACT 10 GPM JOYSTICK CONTROL VALVE

I understand that if this is the correct valve/spool, I'll need hoses and a good mounting point...but will I need anything else ?

Would I plumb this through/from the existing remote ?

If you haven't figured it out I'm a total hydraulic novice !!:laughing:

thanks in advance for any advice...

Does the valve that controls the existing remotes have a 'Power Beyond' port? if so then you install a plug and plumb the new valve from the PB port on the existing valve...the return line can be Tee'd to the existing return...

/pine, I'll have to check this afternoon...don't know the answer off the top of my head..."the return line can be Tee'd to the existing return"...do you mean the return to the existing remote, tee'd in before the return gets to the remote, right ? sorry for what appears to be stupid questions but I really don't know diddly about hydraulics...lucky to spell it correctly...instead of tee'ing in to return, could the power beyond from this new valve/spool be utilized for the third function and then returned to system somewhere else ?

Thanks for ya patience !

The return (low pressure) line gets tied back into the (any) return line going back to the tank...

You get pressure from the PB port on the existing valve...i.e.,:

plumb PB port on existing valve to the "IN" or "pressure" port on the new valve

The return or "tank or OUT" port gets teed into the return on the existing valve

You will need the power beyond "plug" for the existing valve (this allows the fluid to go to the new valve instead of returning to the tank)

The power beyond port on the new valve would only be used if you need to add an additional control valve...

The member "J_J" will be able to advise you on the best valve etc...(he watches this forum and will reply)

 

[/pine]

just to clarify...

The "remotes" (ports) are the (2 for each spool) working ports (usually w/quick disconnects)...these are separate from the In and Out ports on the valve body...

If you already have one set of remote QD's and you add a 2 spool valve (for T&T) your original remote set will be your 3rd function use...

If you want to use a joystick for your next 3 remote outlets, why not just install a bank of 3 diverters and use the FEL control valve? That way you would have control of 5 functions all from your loader joystick. My understanding is that John Deere does this exact thing on some of their tractors.

 

[Biggreenavalanche]

ok, think I've got the gist of it...basically, everthing starts at tank and eventually returns to tank, nothing will end at valve/spool, last spool goes to tank or return line...so from existing "qd", remove pb plug, replace with pb sleeve to high pressure side of new valve, from low pressure side, pb sleeve to either the next valve in line or return to low pressure on previous valve...either way, end up at a low pressure point or tank ?

Rich

 

[Biggreenavalanche]

mtview...nope, just the joy stick for T&T...looking at an install for the valve/spool on left side of tractor, behind/beside seat...for the third function, i want to use a simple push button toggle, one button to push (and hold down) to close, one button to push (and hold down) to open...or something along those lines...want to install the button on the existing joystick for one hand operation of the grapple...

I know, picky picky picky... LOL

Each valve will need a return (to tank) line (can be teed together)

The original pressure line comes from the pump (and returns to the tank) PB ports give you access to this pressure

on the new valve you will NOT use the internal plug or sleeve on the PB port...it will just get capped off...

 

[Biggreenavalanche]

ok, gotcha...so for a two spool there will be two return lines from the spool...and those can be tee'd together...

told ya, total newbie at the hydraulic thing...

Thanks

Rich

 

[J_J]

All valves in series should have and use the PB port.

You can use that joystick valve as the T-N-T valve and one of the spools will have float.

For your grapple, use a diverter/selector valve. and the default will be the tilt.

Press the button and you now have grapple. The switch can be momentary or lock on for continuous grapple work.

No there will only be one return (Tank) port on the valve body regardless of how many spools...but the return from the new valve can be teed into the existing return on the existing valve...

 

[Biggreenavalanche]

/pine - ok, got it now...thank you so much for the patience !!

J_J, do you have a recommendation for the diverter/selector valve ? I assume for that I would utilize the PB port on the joystick valve ?

Thanks,

Rich

 

[J_J]

NO NO, the selector valve goes to the tilt hyd circuit, and here is the valve that most people use.

Your joystick valve will operate the lift , tilt, and grapple using the selector valve.


Surplus Center - 12 VDC 13.2 GPM SAE 8 DOUBLE SELECTOR VALVE

You remove the hoses that go to the tilt circuit and connect them to the IN port of the selector valve, and then connect the tilt cyl hose to circuit one, and the grapple to circuit two.

Default mode with no voltage is tilt.

 

[Biggreenavalanche]

J_J...ok got it now...thanks and thanks for the recommendation on the valve...

I know this will sound redundant but here goes...so from my existing remote I will utilized the PB to the input side of the joystick valve, from output of joystick valve I will go and tee into return, from joy stick tilt (high and low) to diverter P1 and P2, from diverter to C1/C2 for tilt, C3/C4 for grapple, then add power and switch of choice...? I think I've got it right...again, please excuse my ignorance !! Plus, go to hydraulic hose shop and have them make up correct hoses with appropriate terminal fittings...

Rich

 

[Biggreenavalanche]

just re-examined the diagram, it appears C1 and C4 are together and C2 is with C3...

 

[J_J]

Let me make sure You do have a loader now, correct.

You also have one remote and want to add a joystick valve for another remote?

If all that is true, then after adding the joystick in series with the one remote, you can use either joystick valve with the one selector/diverter valve.

The loader valve would be the easiest to run hoses.

Let me know if what I said is correct. I may have to advise otherwise.

 

[Biggreenavalanche]

yes, correct, have a loader, planning on adding the grapple

I have one factory remote, and have a kit from Mahindra to add a second "factory" remote...just have not added it yet...

I want the ability to do hydraulic top and tilt and like the idea of T&T controlled by joystick...

Rich

 

[Biggreenavalanche]

took me a second...I understand you now...you're saying I can add the diverter valve to the factory joystick, putting the diverter up front by the factory loader valve, shorter and easier to route hoses...if I've got that right then for my add on T&T it would be in from PB, out to return, with appropriate T&T connections...also, the diverter would be different, correct ?

Rich, a couple of questions.
Are you going to be doing very much grading?
What type of terrain?
Are you going to do any rough cut mowing?
What type of terrain?

You may want to have the float function for both of the "TnT" cylinders. Depends on just what you will be doing and your conditions.

Something to think about.
