Tmod, welcome to the forum. I read your blog on your website. When you write that Kioti says this condition is normal, or that they designed it that way, I'm curious who you spoke with? Was it someone at a dealership? A technician at Kioti U.S. in Wendell? A regional tech support rep? I certainly would not accept that this is "normal" for a brand new CK3510SE HST. And it is nuts that a new owner would have to modify the hydraulics with a flow control valve in order to achieve proper balance in the circuit!
Is Kioti corporate actually saying that air is entering the curl/dump cylinders as you dump because the pump can't keep up? If so, is it because air is leaking past the gland seals every time you dump? Seems to me that this is a covered warranty issue, and that there's got to be more to this story. :scratchchin: You are certainly entitled to more than a DIY workaround mod that might conceivably even jeopardize your warranty coverage later on.

As I mentioned earlier in the thread, I have a 2018 CK3510SE HST, as does one of my neighbors. Both tractors have the same KL4030 loader that's on yours. I am
unable to replicate the condition you describe on
either tractor. No slop in the dump/curl function, either at the cylinders or the wrist pins. No slop or loss of position when back-dragging with the bucket or a grapple.
And that is what I tried to explain to Kioti is others don't have the issue so if it was designed that way how can mine function like it does as well as several others I have talked to but yet 60% of the owners don't have this issue. I talked to three techs at Kioti Wendell and my dealer and another dealer in Oregon.
There is quite a bit of slop in the arms and pins on the loader as well, This is on a new 2019 CK3510 and I know they changed the lift control valve for the 3ph and who knows what they did with the loader hydraulics.
Very disappointed with Kioti in regards to the bucket issue and the extremely jerky 3ph. They just say normal as designed so that leaves me no recourse.
Below you will read actual replies from Kioti and they are saying all the tractors do it I just never noticed it, BS reply but if Kioti states it is normal even though we know it is not it sort of ties one hands for a resolution.
What I sent in first,
"Hi, I had purchased this tractor due to a neighbor having the same tractor but his is a few years older then mine. He has no issues that I have.
The 3 point will judder now and it didn't when it was new, Here is a link to a video showing what i have to go through when I raise my rear 3 point implement.

Now on to the FEL, Seems this thing cavitates when rolling the bucket down, I have tried at 2600 rpm and it still creates cavitation even if I move the bucket a few inches, Almost like the down roll side of the hydraulics has a restriction in it or the pump is not flowing what it should.

So my question would be why did the 3 point not jump when it was new but now with 20 hours it jumps?
Had issues day one with not being able to back drag as the bucket will roll flat.
At this point in time I am very dissatisfied with the tractors performance and feel like I wasted 30K on something that does not perform the way it should."
Kioti Reply
"Thank you for your email. The valve on your 3-point is either open or close. You have to revat high RPM raise up then lower. To eliminate the cavitation tilt the bucket down until it stops this will get the air out of the cylinder.

Reply to that statement from Kioti,
"Hi,
I can raise the rpm to 2600 rpm and roll the bucket down and then back up a little bit and it will cavitate and still have air in it, Basically even at high rpm it will cavitate after fully rolling the bucket up and down.
If the 3 point valve is either opened or closed why did it not judder when it was new? Seems like a contradiction that it is normal if I had no judder when new and now I do. Normal doesn't work that way."
Kioti Response to that,
"You might not have noticed it. All of the smaller tractors do this.
