I think I have my first issue.....CK2610

Question, I thought only the lift cylinders float? Not the curl.

That is true.

When you are dumping the bucket, the weight of the bucket plus the rock pushed the fluid out faster than the pump can refill the back side of the cylinder causing cavitation within the cylinder. So when you put it on the ground to back drag there is not enough fluid in the backside of the cylinder to hold it in place. You have to push to dump the bucket to get more fluid in the bucket cylinders to make is steady.

In float position there is no down pressure. If you back drag with down pressure and the bucket curled forward there's a good chance you'll bend the cylinder rams for the bucket.

Well, maybe in an extreme case where you're moving fast backward and slam the bucket into, say, a hidden stump. But I respectfully disagree with this as a general statement. Back dragging with down pressure even with the bucket at full dump is an accepted technique to position material when working a pile of dirt, gravel, etc. Don't have a CK, but knowing how stoutly Kioti builds their machines I can't imagine that series is not up to that. :thumbsup:

Threepoint I made this statement from experience In the past I've bent curl arms a few times and know of a few others who have don the same thing. I've not done it with the Kioti. It does happen when the bucket is at full curl and you hook something and try and pull it.

My loader and I think all of the CK's have float (if you want to call it that) on the curl when you push the lever all the way to the right. If you only push it half way it will power it, then past that point it floats. Try putting your bucket flat on the ground then proceed to dump the bucket, going halfway it should raise the front end, if you go further it should float back to level or where ever weight takes it. the loader arms have the same function just that it has a detent to hold it in the float position.

Agree completely, have never bent or broke anything and I've done a lot of backdragging with my CK.

I've never tried that. Will that work on the DKs also?

 

[TBDonnelly]

When cylinder rods are fully extended, like when the bucket is fully curled and angled toward the back of the tractor, the cylinder rods are at their most vulnerable position.

I think that's what we would call "fast dump" or "regenerative bucket dump circuit" on a Kubota, but I haven't heard it described the way you are describing it. Normally it's used so that you don't get a floppy bucket when dumping a load (since in that situation, gravity can pull the bucket down faster than the hydraulics can keep up). Fluid is pumped into both sides of the cylinder, under pressure, but the net direction is still dumping due to volume differences across the cylinder and piston, and gravity.

Float on the lift arms is a little different in that it simply connects both cylinder hoses together so that fluid can freely flow in both directions as the cylinder moves in and out. No pressurization in that case.

If I would use the "fast dump" I might not get the floppy bucket for back gragging, but I rarely seem to use it for some reason.
If I remember I'll try it next time.
