Why float valve for Boxblade tilt?

[KTM300]

I have a B3030 with one Double Acting rear remote installed used mostly for a top link. I'm interested in a hydraulic tilt link and have been reading posts. From the Kubota catalog, in the second position I can install either another DA or a Float Detent Valve.

I've heard posters mention wanting the float valve for a tilt cylinder. What's the advantage there?

Wouldn't the boxblade then follow the contour of the ground without cutting in at either edge?

Wouldn't that make it difficult to initially cut a ditch if the side wouldn't maintain the angle it's set to?

Does the Float valve only float in detent?

Does it stay put when not in detent?

I would think the DA valve would ensure the boxblade would maintain the angle set by the operator so it would cut in.

If a Float valve would maintain it's position when NOT in detent, then follow the contour when IN detent then I can see that being useful.

What part of this am I getting wrong?

Thanks,

And, the float valve does just that. Just like on a loader.

You have nothing wrong, this is what you want. If you are smoothing a surface, and your intentions are to only smooth out a surface and not change the grade, putting the side link in float mode works very well. You CANNOT do this with a cylinder that has a check valve mounted on it. (dpocv)

So the trade-off is a FLoat valve will allow you to follow a contour in detent but may not hold a non-detent position as good as a Double-Acting valve with a check valve.

Does the Kubota Float Detent valve have a detent at each end so the box blade can follow a contour at either the left or right extreme, or is the detent in the center of the lever throw?

The float is only in the forward movement of the lever. I only have the float detent on the top part of top and tilt. I had not thought about using it for the tilt function but I use it all of the time on the top function.

Well ... Your loader holds position well when not in float doesnt it? Thats what you could expect with the auxilliary valve too. In most cases leakage when the valve is in centered position is very slight so any short term position holding is excellent.

This is what I have found on my "TnT" sets and I have no check valves. On my Mahindra 3215, I have 2" diameter cylinders, after an hour or so of none use (implement is just up and I am using the loader) I notice that the cylinders have moved a bit. Normally this is not a problem because I very rarely have an implement in one position for very long. Normally when I am using an implement on the 3pt I am constantly adjusting it. My Mahindra 7520 has 3" cylinders and I have not noticed any movement with those.

I appreciate all of the replies. I have a much better understanding now. It sure is nice to be able to think about thinks and ask follow-up questions rather than stand in front of the dealer and try to understand everything on the spot. My follow-up questions usually don't come to me until I'm half-way home.

We offer a product you should take a look at: HydrauLink. Its patented design offers some benefits like you are describing here plus a few more that competing designs simply can't match.

Now I'm really confused. :confused2: In what way does your top link have anything to do with a side link? :confused3: I understand that you are trying to push your product here,:thumbdown: but I think that you should call it for what it is and nothing else. It is not a replacement for a hydraulic, it is an alternative type of top link with some different characteristics. It surely is not to be used as a side link.
