Rear Remote Hydraulic Valves

[AGTtactical]

Hi guys. I am ordering an L6060 with 3 remotes, all three float detent double acting valves, and a TNT kit. All ordered and installed by Kubota, probably at the dealership.
Two guys on a another thread have had major leak problems with their valves, and leaks/fitment problems with the TNT. Have any of you had the same problem?

I have three remotes and TNT. Not a Kubota tractor, but no problems.

I don't think you want all three valves to have float detent. usually the first is no detent the second is powered detent and the third can be float detent if you want. I am pretty sure you want atleast one valve that is powered detent or else you will need a bunch of bungee cords to hold the lever into place if ever you want to run a log splitter.

Kubota no longer offers the powered detent in the Grand L series tractors.

Kubota has only two valve offerings in the L Series: 1) A "double acting valve" and 2) a "float detent valve". This is exactly the way they are listed on their website, and the only two options listed there. Someone please correct if I am wrong, but I don't think you lose anything by having a float detent valve; in other words, there is no reason (other than saving the extra $60 for the float detent option) to ever buy only a plain old doubling acting valve without the float option. This is because the float detent valve works like a standard double acting valve, i.e. the float option only works if you push past the stop (resistance point) to the detent position, which then removes pressure. If only for the depressurization option, the float detent is handy so that you can change implements without shutting the tractor down to bleed pressure off before removing the hose. As mentioned by the ever informative MtnView, I don't think there is a powered detent offered...

I am considering skipping the TNT from Kubota though. I'm concerned about it bleeding down while using it. I'm not sure how MtnView solves this problem, but he seems to have good results.

Something to keep in mind, is that is seems like not all the valves have the internal leakage problems. :confused2: You would think that they either would always leak (poor specs), or would not (good specs and quality control). From the feed back that I get, I would say that 15-20% have issues. This is not a precise figure, simply off the top of my head based on my customers that have given me feed back.

What I do know is that Kubota Corporate knows about it and yet will not warranty the problem. If you have a great dealer, either they are absorbing the lost costs or they know how to word things properly that it gets through corporate and they get reimbursed.

But as Fallon has reported, he has had both an improved valve installed and another valve that was no better than was replaced. This shows poor quality control in the manufacturing process of these rear remote valves. A real shame because their loader valves seem to be among the best used in the utility tractor market.:thumbsup:

With an open station tractor, it is relatively easy to mount 3rd party valves. Now they by no means look as nice as the factory units all tucked away under the sheet metal, but in reality they "can actually be more ergonomic and a far better quality valve for less money" than the OEM units.

The other option is always the DPOCV on each cylinder, but then you loose the float feature capabilities that can make life so much better depending on the task and end result that a person is trying to achieve.

I recently bought a new Kubota tractor with a cab. I got the 3rd function for my loader mounted grapple. Also got a 4th and 5th function with rear remotes. I ordered one of the valves to include a float feature and the other without. I wanted to have the float feature for my 3 point disk and have the ability to adjust or let it float....all on the fly.

I got a hydraulic top link WITHOUT a check valve on the cheap from Agri Supply.....and when I used it....it constantly would change positions allot when using my landscape rake. It didn't seem to work very well in float position with my 3 point disk either. When I got around to putting my PAT's EZ Change Quick Couplers on.....it turned out that my cylinder was a bit too short to use in conjunction with the PAT"S.......which I really like.

Anyway.....I decided to bite the bullet and get another cylinder....this time from the Surplus Center.....and I got one with the check valve. Seems to work far better for my needs. ( I gave the "short" hydraulic top link to my son-in-law.....and it will work for him).

The 5th function valve from Kubota turned out to be defective....and I had to take the tractor back to the dealer to get it fixed. Now it works ( they didn't check it before delivery....DUH! My dealer's service department is a bit lacking....IMO.). I was not able to hook up my Woods Stump Grinder this fall.....which was my purpose for wanting the 5th function. It will be ready in spring.

So far I have ground over 2000 stumps out of my property using my old John Deere 3320......where I would use the loader's joystick to operate the stump grinder. I didn't want to go thru that process anymore (although it worked quite nicely) on this new tractor....therefore the extra hydraulic connections.

Not sure how I could have done so many stumps without a good set up for hydraulics. Most of that need is passed me now....but I still have the need for my stump grinder each year....if only for a few stumps here and there. I do like the ability to adjust my top link without stopping and wrenching....as you won't always do that.....and it can be very important to proper operation of some implements. Life is good. .

Maybe my terminology is not correct but I'm pretty sure you can still get a remote valve that will detent into the pressurized position so that if you hook up a log splitter you can actually use it without a bungee cord on the lever. I just priced one from messicks this summer.

I'm sorry but if I buy a 70,000 dollar tractor I sure as **** am not putting a bungee cord on the lever to run my splitter.

Not saying that the valve is not available on a $70,000 tractor. Just not a Grand L. And that is not to say that parts would not have it for a previous model. But currently, a plain detent rear remote valve is not available to be ordered on any Kubota Grand L model.

Relax Francis (name that movie). Read the thread...we were talking about the L series. MtnView is correct as usual. And M Series tractors do instead have Self-canceling Detent Valve option...not offered for L Series. This is a valve where you can put the lever in the up or down position and it will stay there UNTIL the cylinder completes its cycle. Then the lever will return to neutral. It also will have the detent for float in it.
