Rear Hydro Valve Question

[RFB]

Sirs,

I am ordering a Kubota L5740 and specifying 3 rear hydro outlets. The choices given are for "detent" valves or "float" valves.

I also plan to attach (using QA coonectors) a BH to those outlets.

Based upon that intended utilization, what selection should I choose, or does it matter?

Thank you

If you are considering T-N-T, two of the spools should be spring to center, and maybe one of them detent for the BH.

RFB,

I have three remotes on the back of my NH tractor. The outlets I use for my backhoe are dedicated with no control lever connected in the cab, just plug in the back-hoe and go.

The second set of remotes are connected to hoses that run my grapple up front with a centered spring return valve and lever in the cab. The third set have the same type of valve and lever and I use them for my top link on the back of my tractor. Mainly for brush hogging, mowing and raking.

They are position valves that hold the cylinders in position locking them at the point you released the lever.

I can post a pic later today. Just let me know.

brewdog,

Can you explain how you get fluid to the BH through one of the spools on your valve. You say dedicated, but do you not have to activate a lever or something?

No levers to activate. The photo explains it. When the BH is not connected, the power beyond flows back to Hydro tranny case. The connections are jumpered together when the back hoe is off the tractor like you see in the photo.

The Green lever runs my grapple, the blue lever controls the top link.

I can use those same Back Hoe connections for a log splitter that uses the tractor hydraulics and as long a the valve is set up for power beyond. It will plug right in without effecting the Hydro tranny, grapple or top link operation.

I don't see a photo. I knew you had to do something like use a jumper to reconnect the flow. That is what a lot of people are doing instead of a remote valve to run log splitters, and BH.

 

[brewdog]

Sorry, it took a few minutes longer to get it uploaded. Hopefully the photos help. I must say, I really like the entire remote hydraulics arrangement.

The direct connection for the BH helps eliminate additional heat from passing through a valve.

At first I thought the Grapple control might be inconvenient but after having it this way, I really like it. In some ways I believe its better than mounting additional valves on the FEL and buttons on the joy stick.

Mr. Dog,

Kubota lists their remote valves as either detent or float. What one of those choices would you surmise is the "spring to center" type you are using for the lever control options you have attached?

Also, are the two outlets that your BH plugs into specified as remotes or hard plumbed power beyond outlets?

Mr. J,

I do not understand your recommendation re. the top n tilt (which I am getting).

Would you kindly elaborate?



Thank you

T-N-T needs two spools for the operation. One spool for tip, and one spool for tilt. If you only tip, one spool valve will work. If you need any other hyd on the back as in BH, log splitter, then a detent spool valve is good.

Great explanation! I only the Tip cylinder right now. Might be a good idea for RFB to call the Kubota dealer to get that sorted out before his tractor is delivered ASAP. I'm not sure what Kubota typically does for their remotes, I can't imagine they would be any different than NH or the others.

RFB, The one set in the photo that are jumpered together are power beyond remote access outlets. I like having them on the rear for easy access. I had a Ford that I had to crawl underneath below the FEL control to hook up thevback hoe. Not much fun in the winter.

If you get a hoe with a PTO pump from Kubota then you won't need them. For me, I don't need a float valve on the back. The 3pt hitch has a float function built in as does my FEL. I'm not that familiar with Kubota products. Good luck!
