MX6000 Add on Remotes - Float Options?

[MtnViewRanch]

It is rather simple to understand. All float does is allow fluid from one side of the cylinder to pass to the other. On your loader valve, when you push the handle all the way forward, the valve always fluid to flow from port A to port B of that spool. This is internal in the valve.

The same thing would happen if you just put a hose from one end of the cylinder to the other end. Then fluid could move from one side of the cylinder to the other.

That is all the valves I added do. I used electric because of the cab but just a manual hydraulic shut off valve in between the two ports of the same spool would work. Close the valve and the cylinder can be controlled with the remote valve. Open the manual valve and the cylinder can float. You just have to remember to close the valve before trying to adjust the cylinder with the remote valve.

Hope that makes sense.

Based on how I understand what you have done to get float, to get the full stroke in float mode both directions, you would have to have the rod fully retracted to gain the full capabilities of the float feature. If the rod is extended any amount, this limits how far the rod can retract.

You need to have the system connected to the tank also to be able to open the valve in any position and have full capability of the said float feature.

Been there, done that for a guy with an LS tractor.

The sad part of this is that Kubota somehow changed things around where only a single float featured valve in the #2 slot will work. I had a previous customer with an MX5200 that had #2 & #3 valves with the float feature. Maybe the dealer just installed what the customer asked for, not what Kubota said could be done. :confused3:

For the OP, good luck. :thumbsup:

It is sad, and it may well be unnecessary. I'd love to have access to an MX, a couple float style valve slices and an afternoon to mix and match. My gut tells me three valves with float can be made to work but I'm not going to advocate somebody spending the extra cash and prove me wrong. Probably the worst that would happen is the lever wouldn't move far enough to enable the float function.

Brian,

It has worked great all summer for my ditch bank flail. No issues whatsoever and the head follows the ground nicely.

I do understand what you are saying but I personally do not ever have a need to go into float with a cylinder fully extended. Some people may and yes that would present a issue. Depending on where I tied back to tank, I would have the opportunity for air to be introduced into the system.

I agree. On my Branson 4815C the issue would be the lever. There is not a lot of room for anything on this tractor. If it had the float feature, I would not have had the room to add my position control stop. There was not any room for error fabricating the slide. :confused3:

Very helpful discussion...take away is making sure to use accurate terms for the double acting valves and the double acting valves with float.

Having only 1 remote with Float may be less than ideal - but way better than turn buckles, and not a show stopper!

Plan of action:
1. Check the MX with respect to lever travel, specifically slot 2 compared to 1 and 3.

Assuming the footprint is the same for each of the valve slices, I can increase lever travel by metal fabricating with my 4 inch grinder!!!

2. Investigate with the parts/service team a bit more regarding their experience adding a second valve slice with Float on an MX6000, along the line mentioned by Brian with the previous customer with the MX5200 ... "Has something changed?"...

3. I "think" I captured the logic on how adding the solenoid after the fact works...still turning that around in my head.

Always amazed how things become clearer as you start gathering and building related pieces of information together.

Thank you Gentlemen!

Looked more closely at the MX.

Guessing the photo reflects where the levers for the new remotes will go.

The existing 3PH lever is marked on the photo.

Not sure how Kubota numbers the other open slots.

The objective is to determine if slot length is the only thing preventing (2) valves with Float to be installed?

The slot marked 2 on the photo is the middle slot. Rick mentioned this was the slot Kubota indicated to use for the valve with Float.

The slot marked 3 on the photo looks to be about 3/4 of an inch shorter than 2.

It appears to be easily extended with very minimal effort...to make it the same length as slot 2...tagged with a yellow mark in the photo.

At any rate, today I asked the gentleman I'm working with at Messick's to kindly order in (2) valves with Float.

Full speed ahead into the fog!

Please let us know how this works out.

I believe that the slot you have marked as #1 is for the optional draft control.

The 3rd lever should be in line so that there are 3 levers side by side similar to what I have pictured.

It looks like either the PTO button position has been changed or I have this picture labeled wrong. :confused3:

Follow up from Messick's...

Only (1) remote valve with Float is technically supported based on detailed investigation by their shop guys and hydraulics pros...from a "factory install" perspective.

The constraint is the size of the Float valve slice which limits the single instance.

And they confirmed as RickB mentioned about slot 2 as the location.

So, I capitulated...pulling the trigger on (3) remotes, only 1 with float.

Tractor goes on the operating table Monday morning. As mentioned earlier, I might be able to pull off the surgery...but absolutely sure it would be less than what they will do.

I have a glass half full outlook, so 3 Remotes, and TnT with only 1 float will be light-years ahead of the current no remotes and "turnbuckle twist"!

Brian, the MX6000 has the PTO switch moved up on the right fender moulded into the grab bar, so no longer mounted down by the lever plate.

Agree with your comment, believing the longer open slot labeled "1" on the original photo is for draft.

And should Santa be in a Christmas mood...I'll be ready for the Fit Rite TnT magic by end of next week!

Interesting. We have an MX waiting for a PDI slot that includes 2 remotes. I'll be sure to check the available room around the valve stack during the install. Apparently the clearance issue concerns the detent housing. The rest of the valve slice occupies the same space whether with or without float.
