CK4010 RPMs dropping

Your rake bolts onto the bucket sides, from what I can tell about it from the pic you posted.
I'd focus all my energy on getting your tractor fixed and then continue with rakes, and other tools.

Seems to me there is an inherent issue with your tractor's function. It seems both inconsistent and to some extent random. I'd take careful notes detailing ambient temp, how long the tractor can run before it begins acting up, and exactly what it does, and what you were using it for at the time.

What is the current # of hours on the clock? Has it ever done a full regen successfully? What RPMs do you generally run it at when it's NOT messing up?
I just reread your first post. It brings me to ask what EXACTLY did your dealer do to fix your regen around the time of your leg break? What was your tractor doing then, before they 'fixed it' at the time? Did you get to verify the problem actually was resolved, or did you have to let it sit until now?
Have you had any issues with biocide and contaminated fuel with any tractor you've owned? Do you use bio-fuel, ever?

I've been told that trying to keep the RPMs low, by some OPs, causes more issues than it solves. That running them as hard as possible within reason is actually better for the newer models with the DPF system/regen, etc.

I've also heard that some models have needed recalibration of the CPU, and/or replacement, to get the affected tractors running properly. I can't say which models of Kioti, but if its acting up as badly as yours seems to be it could be fuel and another issue combined; though multiple issues concurrently is less likely than one cause/effect, in most driveability situations.

I'd want the Kioti zone rep for your dealer directly involved ASAP and as long as it takes to remedy the issue, or issue a different tractor and take yours back to the barn as exhibit A for them, (Kioti) to solve on their time. You've been patient, but this is getting ridiculous.

I'd start by buying fuel, off road diesel, from a different local supplier, using a brand new container, so you eliminate any possibility that you've contaminated what it seems like the dealer was saying is 'your bad fuel supply'. I'm a little confused by what you said you did recently with your supply of fuel, and are you saying before you added ANY fuel after the dealer drained yours that the hunting RPMs issue showed up again with ONLY their fuel in the tractor?
Sorry for the myriad of questions- but I want to get you off the treadmill and pinpoint accuracy focussed on what the actual problem is so it can be addressed and fixed for good.
You can PM me if you chose to, to answer all the questions, then come back to the forum to continue on, if you prefer.

I知 looking at buying a CK4010 and am in the upstate of SC. I was wondering which dealer youæ±*e working with. Thereç—´ one in Greer I was going to take a look at next week. Thanks and hope you get some good answers on yours. I do wish tractors didn稚 have to have all this extra emissions stuff and could just be new but simple like my Yanmar 3110d from the 80s.

I'm over in Oconee County. Dealer is in Westminster. Thanks for support! They picked it up either late Friday or early Saturday (we were gone) but I'm pretty sure the mechanic is on vacation all week.

Good luck with your visit! We love the tractor, if only we can get past this one issue.

Rake or tooth bar is definitely far from my mind right now!

Seems to me there is an inherent issue with your tractor's function. It seems both inconsistent and to some extent random. I'd take careful notes detailing ambient temp, how long the tractor can run before it begins acting up, and exactly what it does, and what you were using it for at the time.

It is definitely inconsistent.
Ambient temp varies as with any place. When it did it in the fall, temps were in the 80s / low humidity. With my wife a month or so ago, 70s / low humidity. With me last week, high 80s / high humidity.
Runs before acting up again varies. I was on it an hour plus during one occurrence. My wife was on it about 20 minutes. Last week, I was on it 30 seconds. No rhyme or reason.
What is the current # of hours on the clock? Has it ever done a full regen successfully? What RPMs do you generally run it at when it's NOT messing up?
Current hours are about (I知 not home) 38.8 39. The first time I saw the regen light was last week. It came on and stayed on about 15-20 minutes. The odd things about it, which I discussed with my dealer Friday morning, are:
1 - Never 途ev壇 up and down as I致e been told regen will do in order to heat it up.
2 When the flushed the system a few weeks/month back, the cleaned the DPF filter out so it should not have gone into regen for many hours to yet to come.
RPMs I always run them at 2000-2200 whether sitting idle, in gear with PTO engage or not. Only time it is less than that is when I first start it up or when I shut it down (or if the wife comes out and wants to ask me something).

Similar to this, it was dropping RPMs. If memory serves me correctly, they recalibrated the CPU and forced it into a regen. This I believe was around 12-14 hours on the tractor. We were able to get it up and going a few hours before my incident the first of December.


Have you had any issues with biocide and contaminated fuel with any tractor you've owned? Do you use bio-fuel, ever?
I am not a long time tractor owner (ie, experienced). Had a L2800 for about 10 years and had zero issues with fuel. Never used bio-fuel. Always used off-road in the L2800 but have been told by my Kioti dealer to use either but they prefer and sell them with on-road diesel.

I've been told that trying to keep the RPMs low, by some OPs, causes more issues than it solves. That running them as hard as possible within reason is actually better for the newer models with the DPF system/regen, etc.

I've also heard that some models have needed recalibration of the CPU, and/or replacement, to get the affected tractors running properly.

I totally agree. He was there (dealer) and hands on with the cleaning of the fuel system (to my knowledge) and seemed as perplexed as my mechanic was. I pointed out to my dealer on Friday that this will be the 3rd time so I will definitely be pushing for something to happen if it doesn't leave there this time fixed.

I'd start by buying fuel, off road diesel, from a different local supplier, using a brand new container, so you eliminate any possibility that you've contaminated what it seems like the dealer was saying is 'your bad fuel supply'. I'm a little confused by what you said you did recently with your supply of fuel, and are you saying before you added ANY fuel after the dealer drained yours that the hunting RPMs issue showed up again with ONLY their fuel in the tractor?

Yes the issue occurred again with only their fuel in it. I bought a new container, different fuel source, and added that only AFTER it had begun doing the RPM thing again. I was adamant on Friday that it isn稚 a fuel issue in my opinion based on that.

Sorry for the myriad of questions- but I want to get you off the treadmill and pinpoint accuracy focussed on what the actual problem is so it can be addressed and fixed for good.

No worries! I appreciate you taking the time to read and have input. I'll be sure to post updates once they begin working on it again.

You can PM me if you chose to, to answer all the questions, then come back to the forum to continue on, if you prefer.
