CK2610 vs CK3510 vs CK3510SE--all HST

[Blue Planet]

Loyal Kubota guy here, but Kioti specs on paper are pretty compelling. Almost ready to try/buy a Kioti until I briefly tested a CK2610HST today. The vibration was significant--at any RPM. To the point where after just 5 minutes, got off the tractor and my hands and legs were tingling a bit, though that's somewhat due to some issues I have.

1. Anyone here who's tested both a 2610 and 3510 and can comment on vibration differences, if any?

2. I'm presuming the 3510SE has the same exact engine as the 3510--can anyone confirm?

My Kubota M7040 didn't have anything close to this kind of vibration, but that's apples and oranges. Or should I say oranges and oranges. =) But my old tiny Kubota B7100HST was also wayyyy smoother than the CK2610 I drove today.

Liked the design in general. Only operating nit (didn't test loader) was that it was difficult to change ranges, H-M-L. I believe 3510SE has no clutch at all, so that would be interesting.

I suggest you test each machine... Use the loader and run it like it was yours...
We can only go by our own experiences... You have to make sure it works for you.

CK2610 is a 100ci pre tier 4
Ck3510 is a 111ci tier 4.

I have a 2610hst with 68 hours on it. I will say at idle it is a very mechanical motor....lots of noise. Once throttled up to work at about 2000 rpms everything is very smooth. Can't say I ever felt vibrations that bothered me anywhere?

It does vibrate at idle, but once up to operating RPM the 2610 is very smooth. Never drove a 3510 so I cant comment on that.

Did some more digging.

1. 3510 and 3510SE should be the same exact engine. Makes sense.

2. Another dealer acknowledges difficulty when changing ranges. Says partly because it's new.

3. Supposedly the 3510 is considerably smoother and quieter, per this same other dealer, because it's a different engine--common rail, etc. I stupidly didn't try the 3510 yesterday because they were closing up.

The 2610's vibration is a showstopper for me. Still appreciate any thoughts/experience with this issue!

I'm not sure the difficulty with the range changing goes away? I only have 10 hours on mine. I just leave mine in Medium. It almost seems like it's some sort of an alignment issue when changing, because I'll either have no issue going from High to Medium and no way to get in to Low without moving the tractor forward slightly or vice versa.

The only reason I defended the 2610 on vibration is the way you describe it doesn't sound like any 2610 I've tested. Just wondering if it was that specific tractor or if they were all that way?

Honestly I love my 2610, but often wish I would have got the 3510 since the cost was not really much more. However, the 2610 is already too much tractor for my current use so a 3510 would have been even worse lol...

If it's that difficult to shift, and excessive vibration, then perhaps it's a lemon.
My 2610 has over 70 hours on it, but I have never experienced either. Yes, I sometimes have to ride the pedal into a new range, but the gears have to have to mesh, it's not an automatic transmission. Even in a truck, with an auto magic transmission, the transfer case gears have to mesh. It's no different changing ranges in my old JD 850, except I don't use the clutch to ride in the transfer case I the 2610.

The range selector on the HST 2610 does get easier to engage with use. I sometimes throttle down and clutch to change gears.

 

[3rd Coast]

For what it's worth the owner's manual says to use the clutch when changing range.

Yes. I found throttling down helps esp. going into low range.

 

[cphilip]

Ive not experienced any uncomfortable vibration. Ive owned a big Ford 4cylinder before this one. Find it smooth as that one was. And yes... it was a bit tight the first say 20 hours or so when shifting ranges. But its easier every time now. And you do clutch to do that and yes idling down makes it even easier. Also makes it easier when engaging the PTO for that matter. At about 1800 and above RPM, where you operate almost all the time, everything including noise smooths out and purrs like a kitten.

Thanks everyone.

Interesting--yesterday I tested a NH Workmaster 35. The HST I tested was relatively smooth in terms of vibration--better than the CK2610HST. But then also tried the WM35 gear version--first one vibrated/rattled pretty badly where the dash was visibly shaking; next one was better, third one was pretty smooth. What that tells me is that either tolerances aren't great or that quality control is variable from LS. Changing ranges on the HST version is much better than Kioti.

Also tested a CK3510--if anything at all, I'd say slightly less vibration than the CK2610, perhaps due to common rail/electronic. Started up a couple other CK3510s; same. At least they're consistent! Haha.

I have the 2610 gear version with almost 60hrs on it and there aren't any crazy vibrations. The range selector is getting much better to use after a winter of switching between ranges while plowing and moving snow banks. It is defiantly clattery at lower RPMs but like others have said smooths out at high RPMs.

I still think the 2610 runs pretty darn smooth at 2000rpm's. These machines have yet to break in at under 100 hours.

That's where I plow at. Set the throttle at 2000 rpm and start pushing.

My dealer was adamant that you operate the 2610 at 2000 rpm to keep it running good and clean. It has no regen so you want it burning those deposits off as a normal process of operation. And of course if your using the PTO its at 2400 which is wide open throttle so well beyond that minimum. I tend to move and work at about 2100 or so normally.

I have a CK2610 HST and haven't noticed any excess vibration. Seems very normal to me comparing to my neighbor's 15-20 year old Kubota (38 hp I believe) and my former JD 3320. My Kioti will out lift my neighbor's Kubota, but the JD outlifted both...but my JD outlifted both the Kubota and the Kioti...but the JD was bigger than my current Kioti and about the same size as my neighbor's Kubota. I am not sure of the Kubota model number...but can find out. They all make so many variants.

I was annoyed by the JD's steering hydraulic cylinder locations though...too low to the ground and bent the cylinder one it not once, but twice by bumping into hidden stumps over the years. I also had some front axle leaks on the JD.

My Kioti was selected on the basis of finding the most capable machine I could get (highest capacities) under the umbrella of the most reliable options available. I noticed all manufactures seem to have more issues with DPF and tier IV machines...so I looked for the strongest 25 hp tractor with a good reputation and Kioti won in my research. While I am no tractor expert, I did make a a few videos about my findings.

I now have 130 hours on it. I have done the scheduled maintenance...greasing, 50 hour service, checked loader mount bolts (actually removed them and added loctite and retorqued), etc...and have had no issues what so ever other than puncturing the fuel tank with the handle on a seed spreader that I borrowed that I didn't notice stuck so far out and forward I guess so the operator can reach it when it is lifted up without getting off the seat. Ordered a replacement tank without any issues and it was an easy install.

Very good machine and great price point. I would buy it again. I just wish they had more dealers.

P.S. Please excuse the dogs. I own a K9 and manage a business. The main reason for the tractor is to maintain our 9 acres of training areas.
