3-Point Hitch Ck2610 HST - Jumpy 3PH

[bvajgrt]

I have a 2018 CK3510. I have been using the crap out of the york rake and I have not had any bounce issue at all. I have used the rake in two modes, one with the solid top bar, and I have gone up and down with the rake to grade, and the other mode ( if you will ) I put a chain on the top bar, and use it in a float mode, witch works well around the yard.
Just throwing out what I have, and what its doing and not doing. Hopefully you can get this worked out, nothing worse than spending a ton of money on something only to have it not operate to specifications.

Yeah it does suck, but its not a huge deal because not often are you feathering a 3PH slowly up. Just wanted to make sure that it wasn't something I should be worrying about and taking it back to dealer to look at. But based off the responses I've seen so far in this thread it is a common issue that many of are having to deal with. :duh:

​Tindall07,
Thanks for your input, I'm guessing you noticed it as well? If I can give you an example I've had? My Flail Mower (PTO driven) actually scrapes the PTO guard if you raise it up fully (my CK 4010 did this and the dealer fixed it by cutting a notch in the guard for the shaft :-( It's never a good idea to lift a PTO driven implement fast to full height (as Kioti suggest to stop the bouncing) with the shaft running - the increased angle puts excessive stress on the u joins, bearing on the implement, shaft and tractor. So when I'm using my flail and I get in a rough spot I lift the mower a couple of inches (this happens pretty regular with smaller HP PTO tractors (maybe not the 100HP stuff, but definitely with our tractors) so the options are:
1. Stop the PTO and wait for it to run down, then lift it up fast, then lower it again but stop it a couple of inches higher than you had it when it bogged down then restart the mower.
2.Feather it up with the shaft running (like almost everyone else does without thinking about it) but the shaking IMHO is just as detrimental, as it is transferred from the bouncing mower through the running shaft to the tractors bearings.
It's this scenario (PTO Operation that I'm most upset with) Box blades etc you can work around it. But for those of us with PTO driven Equip a $3000 flail with a running PTO shaft bouncing around each time it's moved up is unsettling to me. Sorry for the Long winded story, I appreciate you taking the time to contribute.​

Tindall07,
Thanks for your input, I'm guessing you noticed it as well? To me it's a quality control issue, like buying a new car and them not including the spare tire or donut (on purpose to save money)- not often you have to use it but it does suck when you need it and you thought you paid for it. Cheers

Who knows, maybe one day well see Kioti come out and acknowledge the fact that this was a design oversight and they offer a replacement part up that mitigates the jumping issue. One can hope :laughing: But at this point I wouldn't bring it up to my dealer unless it needed to go back for any other major maintenance.

10-4 thanks

2019 Kioti CK3510SE HC, I have 15 hours on it now, it went in at 3 hours for a faulty control valve. Then noticed 3 point jumps like you wouldn't believe. Kioti won't do anything, talked and emailed them numerous times. Dealer can't do anything because they don't have the parts that would fix it under warranty. Kioti told me that the valve is an on or off valve and you can't "feather" it. Don't know what their R&D was thinking, but they need to be fired. I'm working with dealer now to see if Kioti will reverse the warranty inception so the dealer can sell it as a new tractor if I trade it in. If the manufacture won't stand behind there product, I sure as heck won't own it. Big hit in the wallet, but now it's a principle thing. And now the control valve is going bad, if you try to raise the FEL slowly it starts to go down before the fluid catches up, same rolling the bucket back. 219 Kioti CK351SE HC jerking - YouTube Attached the link to show you what it does.

Holy smokes!!! That is terrible. That looks like the valve or the mechanical linkages are really sticky. I wonder if that could be debris in the valve spool? I have tech data on most pre -10 models but not on the -10 models and I don't know how they differ. The service manuals on the EX models are pretty thorough. The fact this started after some normal behavior indicates (to me) that something failed, which could include debris in the oil fouling the valve. Nobody should have to tolerate this on a new tractor.

The first time I used the 3 point, it did that.

It's not dirt or any impurities in the hydraulic system it's working as designed - it was intended to do that. I'm talking about the bounce and jump in the 3 point hitch. Kioti Korea thought if it was good enough for the Korean built tractors it would be good enough for the Korean designed American Built tractors. I've already gone through this with at least seven dealerships I have polled, some say they've never heard of it but others put the blame squarely on Kioti. Kioti USA they say they are helpless and at the mercy of Kioti Korea, got this from a frustrated dealer. I'm a bit sour as well because my tractor was $50,000 and it bounces and jumps on the 3PH hitch as well. It too is a matter of principle for me

The exposed knob below the front of the seat only controls how fast the 3-pt lowers. In fact, it is common for this knob to get turned accidental (by feet) to the point the 3-pt will not lower at all. But sensitivity for raising the 3-pt is adjusted by a screw on the MLS valve. Some models have a removable plate to access this screw but others require the seat to be removed. See the video in post 4.

Added: If Kioti has truly switched to an inferior, poor-performing MLS valve on the -10 models, disregard all after the lowering discussion. I don't have a -10 model. I don't want a -10 model. And I don't know that much about them.

Hmmm. Sounds just like the older Kubota 2800, 3400, 3700 "Standard L " series. The higher priced Grand L's are butter smooth going up or down, but the "Standard" tractors all had that exact problem. Including the one I owned. One of the reason's I traded it off for the present Kioti. Kubota's stated (by the area rep) solution was if you don't like the "standard" series 3 point, buy a Grand L. So I bought a Kioti. But I bought a top of the line (at the time) Kioti.
