Grapple hook ups

[Guesseral]

The valve you linked to is a closed center valve, and will not work with your open center system.

When the hyd pump is pumping with this system, the hyd fluid is flowing through all valves in neutral.

The first valve can take all of the pump fluid and leave none for the other valves.

If you use the above open center valve and feather the FEL, then you can activate the grapple at the same time.

You can't tee into a hyd series flow as the fluid will take the path of least resistance.

I wasn't the original poster I was only asking the question. I had also given the OP a new part number for the same unit with an open center I guess I should have stated that before I asked the question oops.

So the same question (not with tee but in series) if he used the valve with the open center he should be ok right? I am asking because I was looking at the same valve and had the same idea, but I am also looking at the diverter valve and using the curl circuit it seems way easer!

Yes that valve is OK for a 3ed function, but if you wanted to use a diverter valve, then you could use one of these.

Surplus Center - SAE 8 6 GPM DOUBLE SELECTOR VALVE 12 VDC P15544-2

or

Yea the 9-7852 valve is the one that I had printed out.

I am just trying to justify if doing all of the extra work and spending the extra money is worth it to go the other route. I really can't see any benniffett to going with anything else for a regular Joe homeowne. If I were doing commercial landscaping maybe maybe not. Just how many times would a person need to curl and clamp the grapple at the same time, heck I am not even sure if I am talentated enough to do both at the same time! :laughing:

I agree, waaaaaaaay easier. With my grapple, I have not found one single time that I would have been better off being to be able to curl and close the grapple at the same time. It just is not that big of a deal IMO.

I agree Brian...its just not that big of a deal.

The valve you linked will not work. And if by "tyeing" in you mean to add Tee's that won't work either, all valves must be added in series.

Why would this valve not work?

I assume you where trying to quote me?

It is Closed Center, I know we have already established that and corrected that error-but I was the first to respond. It is also limited to 5 GPM, and according to TractorData the OP's tractor has a flow rate of 9.5 GPM.

And, I believe that style of valve requires power all the time to one of the spools since it's a "spring return to center" type valve. If a fuse blew or a coil failed the flow of oil would be stopped-that could cause overheating and/or other damage if it was not noticed quickly.
